Common Name(s): Glyceryl dimyristate,glyceryl dimyristate,glyceryl ester,natural glycerol-derived emollient
CAS Number: N/a
DESCRIPTION
What It Does: Provides c14 myristic fatty acid emolliency from the glycerol ester with two of three glycerol positions esterified providing hlb ~3–5, plus gentle glycerol humectancy from the backbone after sc esterase hydrolysis.
Why It's Used: Glyceryl dimyristate is selected for c14 myristic glyceryl ester emolliency — the glycerol carrier provides natural origin, biodegradability, and mild glycerol humectancy co-delivery alongside medium-chain emolliency balanced between laurate lightness and palmitate structure from the c14 myristic fatty acid chain.
How It Works: Glyceryl diester: glycerol backbone → mild humectancy + natural origin; c14 myristic chain → medium-chain emolliency balanced between laurate lightness and palmitate structure; sc esterase hydrolysis → free glycerol + fatty acid metabolites.
