Ingredient review
Glyceryl Dihydroxystearate
INCI: Glyceryl Dihydroxystearate
A mild, plant-based emollient that improves product texture and skin feel without clogging pores or causing irritation.
In plain English
Glyceryl Dihydroxystearate is a gentle ingredient made from glycerin and a fatty acid found in castor oil. It helps creams and lotions feel smooth and silky on your skin, not greasy or heavy. It also helps keep the product's texture stable so it doesn't separate. Because it's non-irritating and unlikely to clog pores, it's a popular choice for sensitive and acne-prone skin formulations.

What it is
Glyceryl Dihydroxystearate is a diester of glycerin and dihydroxystearic acid, a fatty acid derived from castor oil. It is a semi-synthetic ingredient that functions primarily as an emollient and emulsion stabilizer in cosmetic products.
How it works
It works by forming a thin, non-occlusive film on the skin's surface, which helps soften and smooth the skin while reducing water loss. In formulations, it helps stabilize oil-in-water emulsions, preventing separation and giving the product a rich, creamy texture that spreads easily.
Pros
Gentle for sensitive skin
Glyceryl Dihydroxystearate has a low irritation profile, making it suitable for formulations designed for sensitive or reactive skin types.
Non-comedogenic texture
It provides emollience without clogging pores, so it works well in products for acne-prone or oily skin.
Cons and cautions
Limited moisturizing power alone
As a lightweight emollient, it may not provide enough hydration for very dry or dehydrated skin without additional humectants or occlusives.
Less researched than common emollients
Compared to ingredients like glycerin or shea butter, there is less published research on its long-term skin benefits.
Best for
- People with sensitive or reactive skin
- Those with oily or acne-prone skin looking for a lightweight moisturizer
Use caution if
- Individuals seeking a very rich, occlusive moisturizer for severe dryness
