GLYCERYL UNDECYLENATE

TL;DR. This ingredient is used mainly as an antimicrobial preservative booster and deodorant-support ingredient. It can also add light emollience and help stabilize formulas that need a broader preservation strategy.

What does GLYCERYL UNDECYLENATE do in a cosmetic formula?

This ingredient is used mainly as an antimicrobial preservative booster and deodorant-support ingredient. It can also add light emollience and help stabilize formulas that need a broader preservation strategy.

Is GLYCERYL UNDECYLENATE clean?

It is generally well accepted in clean-beauty frameworks because it is a fatty-acid ester with low sensitization concern at typical use levels. Mild eye or skin irritation is possible at higher concentrations, so formulators usually use it as part of a balanced preservation system rather than as a high-dose standalone active.

Is GLYCERYL UNDECYLENATE sustainable?

This material is commonly made from renewable plant-derived feedstocks, often linked to castor-derived fatty chemistry and glycerin. It is expected to be readily biodegradable and does not carry the persistence concerns associated with many silicone or fluorinated materials.

Is GLYCERYL UNDECYLENATE COSMOS-approved?

It is generally compatible with COSMOS-natural and COSMOS-organic formulations when the feedstocks and processing aids meet standard requirements, with supplier documentation needed for certification. Its renewable sourcing, ester chemistry, and biodegradability align well with Green Chemistry principles.

How does GLYCERYL UNDECYLENATE work chemically?

The molecule is a glycerol monoester of an unsaturated C11 fatty acid, giving it both lipophilic character and a polar glycerol head group. It is typically used at low levels, often around 0.1 to 1%, and is commonly paired with organic acids, glycols, or other boosters to improve antimicrobial coverage across the formula.
