Common Name(s): Glyceryl stearate succinate,glycerol stearic acid and succinic acid (mixed diester) ester
DESCRIPTION
What It Does: Softens and conditions skin with a light, non-greasy feel.
Why It's Used: Used for its amphoteric-tendency emulsifier; succinic acid group adds polarity and mild anionic character at physiological ph emollient properties; suitable for lightweight skin care where non-greasy texture is key.
How It Works: Ester of glycerol (branched or specialty alcohol) with stearic acid and succinic acid (mixed diester); branching reduces crystallinity and greasiness; provides smooth, dry-oil skin feel.
Typically Found In: Lightweight moisturizers,sunscreens,skin serums,body lotions
