Maltodextrin in Skincare: The Starch-Derived Ingredient Stabilizing Your Moisturizer

Maltodextrin is better known as a food ingredient than a skincare one — it appears in sports drinks, processed foods, and dietary supplements as a carbohydrate and thickening agent. In cosmetics, it serves a different but equally useful set of functions: stabilizing, encapsulating, and protecting sensitive ingredients, while contributing mild skin-conditioning properties of its own. Its presence on the Everyday Hydration Cream's ingredient list is a formulation story more than a skin benefit story.

Maltodextrin is a polysaccharide — a chain of glucose units — produced by the partial hydrolysis of starch, typically from corn, wheat, rice, or potato. The hydrolysis process breaks down the long starch chains into shorter, more soluble oligosaccharides. The result is a white, mildly sweet powder that is highly water-soluble, rapidly digestible (in food applications), and chemically versatile.

In cosmetics, maltodextrin is used in two primary contexts: as a film-forming and encapsulation agent, and as a mild skin conditioner. Its polysaccharide structure makes it effective at forming protective matrices around sensitive molecules — trapping them until they reach the skin surface, where they can be released. [1]

In the Everyday Hydration Cream, maltodextrin likely serves as an encapsulation and stabilization agent for one or more of the formula's sensitive actives — most probably Totarol or the botanical extracts, which can be susceptible to oxidation or degradation in complex water-based formulas.

• As an encapsulant, it forms a protective carbohydrate matrix around sensitive ingredients, shielding them from oxidation, pH fluctuations, and interactions with other formula components that might degrade their activity across the product's shelf life. This is particularly relevant in a formula with as many botanical actives as this one. [1]
• As a film-former, it leaves a thin, breathable film on the skin surface that contributes to a smooth application feel and mild moisture retention.
• As a skin conditioner, its hydrophilic polysaccharide chains attract and hold water at the skin surface, contributing modest humectant activity alongside the formula's primary humectants. [2]

Protects formula actives

Maltodextrin's most important contribution to the skin experience is indirect: it helps ensure that the formula's botanicals and actives remain potent and stable across the product's shelf life. A moisturizer whose botanical actives have degraded by the time the jar is half-used is not delivering what it promises. Encapsulation with maltodextrin is part of how complex botanical formulas maintain their efficacy. [1]

Smooth skin feel and mild film-forming

The thin film maltodextrin leaves on skin contributes to a smooth, comfortable skin feel after application — part of the overall texture experience of the cream. It also provides a modest barrier effect that supports surface moisture retention. [2]

Mild hydration support

As a polysaccharide humectant, maltodextrin contributes to the formula's overall hydration profile at the skin surface — a minor but additive contribution alongside glycerin, aloe, and the other humectants in the formula. [2]

Maltodextrin has an excellent safety record across both food and cosmetic applications. EWG rates it 1 out of 10 with no identified hazards. Not classified as an endocrine disruptor. No reproductive or developmental toxicity concerns. No sensitization data of concern.

Its derivation from food-grade starch sources gives it a natural origin profile, and its long history in food science provides a safety data set that goes well beyond what most cosmetic ingredients have. [3]

One note for completeness: maltodextrin derived from wheat contains trace gluten proteins in its raw starch source, though the hydrolysis process significantly reduces protein content. For individuals with celiac disease or severe gluten sensitivity, topical exposure to wheat-derived maltodextrin is generally not considered a concern — the skin barrier does not absorb intact proteins — but individuals with severe sensitivities may prefer to verify the starch source with the brand.

Maltodextrin is in the Everyday Hydration Cream because a formula this botanically rich benefits from encapsulation technology that protects its most sensitive ingredients. The combination of Cranberry Fruit Extract, Moringa, Neem, Totarol, Lilac Leaf Cell Culture Extract, and Copper Lysinate/Prolinate in a single water-based formula creates real stability challenges — maltodextrin helps address those challenges without adding any complexity or concern to the safety profile.

As covered in Functional Skincare Ingredients 101, thickeners and texture agents contribute to formula consistency and stability. Maltodextrin sits at the intersection of texture agent and formulation stabilizer — a quiet but useful ingredient in a complex formula.
