Ingredient review
Diglyceryl Stearate Malate
INCI: DIGLYCERYL STEARATE MALATE
A mild, non-irritating emulsifier that helps create stable, creamy textures while also softening the skin.
In plain English
Diglyceryl Stearate Malate is a helper ingredient that allows oil and water to mix smoothly in creams and lotions. It is made from glycerin (a natural moisturizer), stearic acid (a fatty acid from plant oils), and malic acid (an alpha hydroxy acid found in apples). Because it is gentle and non-irritating, it is often used in products for sensitive skin. It also leaves a light, silky feel on the skin without being greasy.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic emulsifier created by combining glycerin, stearic acid (from vegetable sources), and malic acid. It belongs to the class of polyglyceryl esters, which are known for being mild and biodegradable.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. This prevents a cream or lotion from separating. Additionally, it deposits a thin film on the skin that helps lock in moisture and leaves a smooth, non-tacky finish.
Pros
Very gentle on skin
Diglyceryl Stearate Malate has a low irritation and comedogenic risk, making it a safe choice for sensitive or acne-prone skin types.
Improves product feel
It creates a smooth, non-greasy texture that spreads easily and leaves a soft finish, enhancing the user experience of creams and lotions.
Cons and cautions
Not a treatment ingredient
Its primary function is to stabilize formulas and condition the skin, so it does not provide targeted anti-aging, brightening, or acne-fighting benefits.
Limited to emulsion-based products
It works best in water-and-oil mixtures and is not used in water-free or powder formulations.
Best for
- Anyone with normal to sensitive skin looking for a gentle moisturizer or cream
- People who prefer products with mild, plant-derived emulsifiers
Use caution if
- Those with a known allergy to any of its components (rare, but possible)
