The definitive scientific reference for PENTAVITIN® — its botanical origins, molecular binding mechanism, clinical evidence, how it compares to Hyaluronic Acid, and the formulations that use it correctly.
At some point — possibly late at night, possibly after the third week of applying moisturiser that stopped making a measurable difference — you searched for something more specific than "hydrating skincare." You searched for the ingredient itself. What it is made of. How the molecular mechanism works. Whether the 72-hour figure on the label is clinically supported or marketing copy.
This codex is the answer to that search.
PENTAVITIN® is a patented moisture-binding ingredient developed by DSM-Firmenich — one of the world's leading ingredient science companies. It appears on cosmetic ingredient labels under its INCI designation: Saccharide Isomerate. It is a plant-derived carbohydrate complex with a clinically documented ability to bind to the skin's keratin structure and support moisture retention for sustained periods — through daily washing, through perspiration, through the low-humidity conditions of an air-conditioned room at 18°C.
It is not a humectant in the conventional sense. It does not attract water from the atmosphere. It binds to the skin itself. What follows is a complete scientific reference on how, why, and for whom.
What Is PENTAVITIN®?
PENTAVITIN® is a registered trademark of DSM-Firmenich, a global ingredient science company with research facilities across Europe, Asia, and the Americas. It is not a generic ingredient available freely on the market — it is a proprietary technology with specific quality standards, concentration specifications, and clinical testing conducted by its manufacturer. The ® symbol on the label is not marketing decoration. It designates a registered trademark that has passed the clinical and regulatory requirements for that status.
PENTAVITIN® (INCI: Saccharide Isomerate) is a plant-derived carbohydrate complex that functions as a moisture-binding agent in skincare formulations. Unlike conventional humectants such as glycerin or Hyaluronic Acid — which attract and temporarily hold water molecules — PENTAVITIN® works by physically binding to the keratin proteins in the skin's outermost layer, the stratum corneum. This keratin-binding mechanism allows it to support moisture retention for up to 72 hours in leave-on formulations, and up to 24 hours in rinse-off applications, independently of ambient humidity conditions. It appears on ingredient labels as Saccharide Isomerate.
What Is PENTAVITIN® Made From? The Botanical Origin
PENTAVITIN® is derived from plant sources. Saccharide Isomerate is a carbohydrate complex — a family of sugar-derived molecules whose specific molecular geometry enables their affinity for keratin proteins in human skin. The botanical origin carries two significant implications for the formulator and the consumer. First, it places PENTAVITIN® within the category of naturally-derived actives — plant-sourced, not petroleum-derived, and compatible with clean formulation standards that exclude synthetic petrochemical ingredients.
Second — and more structurally important — the carbohydrate architecture of Saccharide Isomerate is precisely what gives it keratin affinity. The molecular geometry of sugar chain structures is complementary to the protein surface of keratin in a way that enables hydrogen bonding between the two. This is not accidental chemistry. It is an engineered molecular relationship: a sugar-derived molecule selected and processed specifically for its structural compatibility with the skin's own proteins.
The manufacturer is dsm-firmenich. Vase Creation® uses PENTAVITIN® as an active ingredient. The keratin-binding technology, clinical studies, and ingredient certification are dsm-firmenich's. The formulation decisions — how PENTAVITIN® is delivered, at what concentration, and in what product format — are Charlotte T.'s.
How Does PENTAVITIN® Work? The Keratin-Binding Mechanism
The mechanism behind PENTAVITIN® requires a clear understanding of what it is binding to.
The stratum corneum is the skin's outermost cellular layer — a tightly packed matrix of corneocytes (flattened, protein-dense cells) embedded in a lipid mortar of ceramides, cholesterol, and free fatty acids. The primary structural protein of corneocytes is keratin. The molecular surface of keratin contains specific amino acid residues — chemical sites capable of forming hydrogen bonds with compatible molecules. PENTAVITIN®'s Saccharide Isomerate molecules interact with these keratin sites through hydrogen bonding. The result is molecular anchoring — the ingredient attaches to the skin's protein matrix rather than sitting in the water phase of the skin or floating on its surface.
This distinction has direct functional consequences. Most hydrating skincare ingredients — including glycerin, propylene glycol, and sodium hyaluronate — function as humectants. They attract and hold water molecules in a gel-like matrix. They are effective, well-studied, and widely formulated. But they are present in the skin's aqueous phase: subject to evaporation, to perspiration, to rinse-off, and to the atmospheric humidity conditions that govern how much water is available to attract.
PENTAVITIN® is not in the aqueous phase. It is attached to the protein matrix. It does not evaporate. It is not removed at the same rate as surface humectants when the skin perspires or encounters water. It continues to support moisture retention because it is bound to the structure that retains it — not to the water that moves through it.
Binding vs. Coating — The Critical Distinction
The most persistent misconception about moisturising ingredients is that hydration means surface occlusion: a layer of something sitting on the skin and preventing water from leaving. This is coating. It is a legitimate and functional mechanism — many emollients and occlusives operate this way — but it is fundamentally a surface intervention. Remove the coating layer and the barrier returns to its previous state.
Binding is a different category of mechanism. An ingredient that forms hydrogen bonds with the skin's keratin structure is not removed by the same means as one that coats its surface. It persists through daily activities — through perspiration, through water contact, through the natural desquamation cycle of the stratum corneum — at a rate governed by the molecular bond rather than by evaporation or mechanical removal.
The 72-hour claim associated with PENTAVITIN® refers specifically to the duration of this binding under clinical conditions — not to the duration of a surface film. It is a measure of molecular attachment, not of topical coating.
PENTAVITIN® vs. Hyaluronic Acid — What Changes in Tropical and Air-Conditioned Environments
This is the comparison that ingredient-conscious consumers in Singapore, Kuala Lumpur, and urban Southeast Asia search for most specifically. It deserves a direct, complete answer. Both PENTAVITIN® and Hyaluronic Acid are widely used hydrating actives. They are not interchangeable. They operate through different mechanisms, perform differently across humidity conditions, and serve different formulation objectives.
Hyaluronic Acid
Hyaluronic Acid (HA) is a glycosaminoglycan — a large, naturally occurring sugar-protein molecule present in skin, joints, and connective tissue. As a topically applied humectant, it is capable of holding significant amounts of water relative to its own weight. In high-humidity conditions — outdoor tropical heat at 80-90% relative humidity — this capacity is meaningful. HA draws moisture from the surrounding atmosphere and holds it at the skin's surface, creating an immediate and perceptible hydration effect.
The humidity-dependent limitation: in low-humidity environments — sealed air-conditioned offices and bedrooms at 40-50% relative humidity, aircraft cabins, climate-controlled retail and commercial spaces — the atmospheric moisture that HA requires to perform optimally is substantially reduced. Under these conditions, the humectant mechanism functions with less efficiency. The moisture-drawing gradient may shift toward the skin's own deeper layers rather than the environment — a consideration particularly relevant for skin already experiencing barrier compromise.
PENTAVITIN®
PENTAVITIN® does not draw moisture from the atmosphere. It binds to the keratin layer of the stratum corneum and supports the skin's own moisture retention from within the tissue structure. It does not require atmospheric humidity to function. Its performance in a sealed, air-conditioned office at 18°C and 40% relative humidity is not significantly different from its performance in outdoor tropical conditions at 32°C and 80% humidity.
For consumers whose daily environment involves frequent movement between outdoor tropical temperatures and air-conditioned interior spaces — the thermal shift that defines daily life in Singapore, Kuala Lumpur, Penang, and other urban SEA centres — this humidity independence is a practical advantage.
The Rational Conclusion
HA excels in humid outdoor conditions. PENTAVITIN® performs consistently across humidity ranges. A well-formulated skincare routine for tropical climate with significant air-conditioning exposure may incorporate both — HA addressing immediate surface hydration in humid contexts, PENTAVITIN® serving as the consistent moisture anchor regardless of ambient conditions. They are not competing ingredients. They are complementary mechanisms.
The Clinical Evidence — What the 72-Hour Claim Is Based On
The 72-hour moisture binding figure associated with PENTAVITIN® is derived from clinical in vivo studies conducted under controlled conditions. In vivo means the testing was performed on human subjects — not in laboratory cell culture or on artificial skin models.
The specific measurement instrument is corneometry — an instrument that measures the electrical conductance of the stratum corneum, which correlates directly with its moisture content. A corneometer reading taken at the point of application, then at 24, 48, and 72 hours subsequently, provides a time-series measurement of how long the moisturising effect persists across the keratin-bound ingredient.
Under clinical conditions, PENTAVITIN® in leave-on formulations demonstrates measurable moisture retention at the 72-hour mark. This is the basis of the claim — not marketing extrapolation, but instrument-measured data from human skin testing conducted by dsm-firmenich.
PENTAVITIN® in Rinse-Off Formulations — The 24-Hour Evidence
Rinse-off applications — shower gels, body cleansers, cleansing oils — present a different clinical context. The ingredient is applied to wet skin and rinsed away before the full binding process has had time to complete at maximum depth.
Clinical in vivo studies on PENTAVITIN® in rinse-off formulations confirm that the keratin-binding process initiates during the wash contact period and continues to support moisture retention for up to 24 hours after rinsing — including under conditions of daily showering. The mechanism is the same keratin affinity: even partial binding during the minutes of wash contact is sufficient to establish a moisture-retention effect that persists beyond the shower.
Charlotte T., Lead Chemist and co-founder of Vase Creation®, confirms this clinical basis in the context of Vase Creation's own rinse-off formulations: "Clinical in vivo studies confirm PENTAVITIN® continues to hydrate even with frequent daily showering, preventing the tight, dry feeling post-wash."
Which Skin Types Benefit Most From PENTAVITIN®?
PENTAVITIN® is appropriate for all skin types. Its binding mechanism does not interfere with sebum production, does not alter the skin's pH, and does not carry a comedogenic risk that would make it contraindicated for oily, combination, or acne-prone skin.
That said, specific populations derive disproportionate benefit:
Sensitive and Eczema-Prone Skin
For skin with a compromised barrier — from atopic dermatitis, chronic sensitivity, or cumulative cleansing damage — the ability to support moisture without relying on heavy occlusive agents is significant. PENTAVITIN® supports moisture retention through keratin binding rather than surface occlusion, meaning it does not impair the barrier repair processes that occur overnight, does not create the follicular congestion risk associated with heavy wax-based formulations, and does not require the high-molecular-weight emollients that can feel suffocating on reactive skin.
Skin Exposed to Daily Air Conditioning
As established in the Hyaluronic Acid comparison above: consumers whose daily environment alternates between outdoor tropical conditions and air-conditioned interior spaces benefit specifically from a moisture-binding ingredient whose performance is humidity-independent. This includes office workers in Singapore's CBD, frequent travelers between regional cities, and anyone spending significant time in climate-controlled environments.
Dry and Chronically Dehydrated Skin
The distinction between dry skin (lipid deficit) and dehydrated skin (water content deficit in the stratum corneum) is clinically relevant here. PENTAVITIN® addresses dehydration specifically — the water retention capacity of the stratum corneum. For true dry skin with a lipid component, a complementary emollient or ceramide-supporting ingredient addresses the lipid deficit while PENTAVITIN® addresses the moisture component.
Frequent Showerers
Clinical evidence specifically tested daily washing scenarios and confirmed that PENTAVITIN®'s moisture-binding effect persists with daily use. For consumers who shower once or twice daily, the rinse-off binding mechanism means the ingredient is continuously reinforced rather than depleted with each wash cycle.
How to Identify PENTAVITIN® on an Ingredient Label
PENTAVITIN® does not always appear by its trade name on cosmetic ingredient labels. All cosmetic products sold in Malaysia, Singapore, Australia, and the European Union are required to list ingredients by their INCI (International Nomenclature of Cosmetic Ingredients) designation — the standardised global naming system for cosmetic ingredients.
The INCI name for PENTAVITIN® is: SACCHARIDE ISOMERATE
Ingredient lists are presented in descending order of concentration — the first ingredient is present in the highest quantity; the last in the smallest. The position of Saccharide Isomerate in the list indicates its relative concentration within the specific formulation.
On Vase Creation® products, Saccharide Isomerate is present in both the Midnight Shikoku Shower Oil and the Skin Elixir Serum Lotion — confirmed on the product ingredient labels of both formulations.
PENTAVITIN® in Vase Creation® Formulations
Vase Creation® incorporates PENTAVITIN® (Saccharide Isomerate) across two distinct product formats — a rinse-off cleanser and a leave-on moisturiser. Each format uses the keratin-binding mechanism in a different delivery context, creating complementary functional roles within a complete body care routine.
The Midnight Shikoku Shower Oil — PENTAVITIN® in a Rinse-Off Context
The Midnight Shikoku Shower Oil is a sulfate-free, soap-free face and body cleanser built on a gentle plant-derived surfactant system. Lauryl Glucoside and Coco-Glucoside — both plant-derived glucoside surfactants — form the primary cleansing backbone, supported by two amphoteric coconut-derived surfactants that improve skin compatibility and reduce the pH disruption associated with conventional anionic cleansers.
Within this formulation, PENTAVITIN® (Saccharide Isomerate) initiates its keratin-binding process during the wash. Clinical in vivo studies confirm that within the contact duration of a typical shower, sufficient binding occurs to support moisture retention for up to 24 hours after rinsing — even with daily use.
The aromatic profile — a citrus character evocative of Japanese Yuzu, softened with mild green tea fragrance notes — is formulated with sensitivity in mind. The product is pregnancy-safe, dermatologically tested, and suitable for sensitive and eczema-prone skin.
Winner of the Beauty Insider Award: Best Body Wash. Available in 330ml and 100ml travel size.
The Midnight Shikoku Shower Oil is available through the Vase Creation store.
The Skin Elixir Serum Lotion — PENTAVITIN® in a Leave-On Context
The Skin Elixir Serum Lotion is a lightweight gel-cream formulation designed for full-body application. In a leave-on format, PENTAVITIN® has the full contact time required for comprehensive keratin binding — supporting moisture retention for up to 72 hours per application under clinical conditions.
The formula combines PENTAVITIN®'s moisture-binding mechanism with Niacinamide (Vitamin B3), which supports ceramide synthesis within the keratinocyte and reinforces the skin's lipid barrier architecture. The combination addresses both dimensions of skin hydration simultaneously: water retention through PENTAVITIN®'s keratin binding, and barrier lipid support through Niacinamide's ceramide-synthesis upregulation.
The serum-lotion format — lightweight, water-continuous, non-greasy — is designed to absorb within seconds and remain compatible with the skin's own sebum output in high-humidity conditions. It does not sit heavily on the skin in tropical heat. It does not create the congested, tacky surface film that heavier emollient formulations produce when combined with elevated ambient humidity and increased sebum production.
Available in 200ml and 40ml travel size.
The Skin Elixir Serum Lotion is available through the Vase Creation store.
The Unbroken Routine — Using Both Together
For those building a complete PENTAVITIN®-active body care routine, the two formulations function as sequential steps in the same ritual rather than alternative choices.
Step 1 — Midnight Shikoku Shower Oil cleanses the skin and initiates the first keratin-binding event of the day. The acid mantle is preserved. The barrier is not stripped.
Step 2 — Skin Elixir Serum Lotion, applied to damp skin within three minutes of the shower, extends the keratin-binding process with the full contact time of a leave-on formulation. Niacinamide reinforces the barrier lipid architecture simultaneously.
The outcome is not additive — it is compounding. A cleanse that does not deplete, followed by a leave-on that binds to what the cleanse preserved.
Frequently Asked Questions About PENTAVITIN®
What is PENTAVITIN® made of?
PENTAVITIN® (INCI: Saccharide Isomerate) is a plant-derived carbohydrate complex developed by dsm-firmenich. Its molecular structure consists of sugar-derived saccharide chains processed specifically for their affinity to skin keratin proteins. It is not a synthetic petrochemical derivative.
What does PENTAVITIN® do for skin?
PENTAVITIN® binds to the keratin layer of the stratum corneum and supports the skin's natural moisture retention. Unlike conventional humectants that attract water from the atmosphere, PENTAVITIN® anchors to the protein matrix of the skin — maintaining moisture retention regardless of ambient humidity. In leave-on formulations, up to 72 hours. In rinse-off applications, up to 24 hours. Both figures are supported by clinical in vivo data.
Is PENTAVITIN® better than Hyaluronic Acid?
They perform different functions and are not directly interchangeable. Hyaluronic Acid attracts atmospheric moisture — highly effective in outdoor humid conditions. PENTAVITIN® binds to keratin and functions independently of atmospheric humidity — consistent in air-conditioned environments. For the tropical-urban consumer who alternates daily between humid outdoor air and dry air-conditioned interiors, PENTAVITIN® provides more reliable baseline hydration. Both can coexist in a routine without conflict.
Is PENTAVITIN® safe for sensitive and eczema-prone skin?
Yes. PENTAVITIN® does not alter the skin's pH, does not disrupt the acid mantle, and carries no comedogenic risk. Vase Creation®'s PENTAVITIN®-containing formulations are dermatologically tested and pregnancy-safe. For eczema-prone skin specifically, the moisture-binding mechanism supports barrier hydration without the heavy occlusive agents that can cause follicular congestion or impair overnight barrier repair.
Does PENTAVITIN® wash off in the shower?
Not entirely. Clinical in vivo studies confirm that PENTAVITIN® initiates keratin binding during the wash contact period. Even in rinse-off formulations, the bound fraction remains attached to the stratum corneum's keratin structure and supports moisture retention for up to 24 hours after rinsing — including with daily showering frequency.
Where can I buy PENTAVITIN® skincare in Malaysia and Singapore?
Vase Creation® currently features PENTAVITIN® across both its cleansing and leave-on body care range — the Midnight Shikoku Shower Oil and the Skin Elixir Serum Lotion. Products are available online at vasecreation.com (MYR) with delivery across Malaysia and to Singapore. Physical retail partners in Malaysia include Tsutaya Books and Mano Plus, among 20+ selective lifestyle locations* nationwide.
Can PENTAVITIN® be used every day?
Yes. Clinical in vivo studies on PENTAVITIN® in rinse-off formulations specifically assessed daily use scenarios and confirmed that the moisture-binding effect persists with frequent daily washing. Daily application does not diminish efficacy — the keratin-binding mechanism is reinforced with each application rather than depleted.
What is Saccharide Isomerate?
Saccharide Isomerate is the INCI (International Nomenclature of Cosmetic Ingredients) name for PENTAVITIN®. It is the name that appears on cosmetic product ingredient labels in Malaysia, Singapore, Australia, and internationally. When you see Saccharide Isomerate on an ingredient list, it identifies the presence of PENTAVITIN® technology in that formulation.
PENTAVITIN® is not a claim. It is a mechanism. The 72-hour figure is not a marketing duration — it is a clinically measured binding response. The botanical origin is not greenwashing — it is a structural fact about the molecule's carbohydrate architecture. The keratin affinity is not a metaphor — it is hydrogen bonding between compatible molecular geometries. In a market saturated with hydration claims and humidity-dependent humectants, an ingredient whose efficacy is independent of the weather is worth understanding precisely.
Vase Creation®'s PENTAVITIN® formulations are available through the official store in Malaysia and Australia.
