Ingredient review
Multi-Acid Glycerides Complex
INCI: Myristic/Palmitic/Stearic/Ricinoleic/Eicosanedioic Glycerides
A gentle emollient blend that helps soften and smooth skin without heavy greasiness.
In plain English
This ingredient is a mixture of fats (glycerides) made from several fatty acids, including myristic, palmitic, stearic, ricinoleic, and eicosanedioic acids. In skincare, it works as an emollient, meaning it fills in the tiny gaps between skin cells to make your skin feel softer and smoother. It also helps other ingredients spread more evenly and can improve the texture of creams and lotions. Because it's a blend, it's generally well-tolerated and unlikely to clog pores.

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 complex mixture of glycerides (fat molecules) created by combining glycerol with a specific set of fatty acids. These fatty acids are commonly found in natural oils like palm oil, castor oil, and shea butter, but here they are synthesized or purified for consistent performance.
How it works
When applied to the skin, the glycerides form a thin, non-occlusive film that reduces water loss and improves skin softness. The different fatty acid chain lengths allow it to absorb at different rates, providing both immediate and longer-lasting moisturization without a heavy feel.
Pros
Gentle on skin
The blend of fatty acid glycerides is designed to be non-irritating and suitable for sensitive skin types, making it a safe choice for daily moisturizers.
Improves product feel
It helps creams and lotions spread smoothly and absorb quickly, so you get the moisturizing benefits without a sticky or greasy residue.
Cons and cautions
Sourcing concerns
Some of the fatty acids may be derived from palm oil, which has environmental and sustainability issues. Look for brands that use certified sustainable sources.
Limited research
While the individual fatty acids are well-studied, there is less published research specifically on this exact blend, so its unique benefits are based on formulation experience rather than clinical trials.
Best for
- People with dry or normal skin looking for a lightweight moisturizer
- Those with sensitive skin who tolerate simple emollients well
Use caution if
- Individuals with a known allergy to any of the component fatty acids (rare)
Usage tips
Safety summary
Generally recognized as safe for topical use. Low irritation and comedogenic risk. No significant safety concerns reported in cosmetic concentrations.
