Cetyl Lactate ●
TL;DR. This ingredient is an emollient and skin-conditioning ester that improves slip, softness, and spreadability in creams, lotions, makeup, and lip products. It can also reduce a greasy feel in oil-rich formulas.
What does Cetyl Lactate do in a cosmetic formula?
This ingredient is an emollient and skin-conditioning ester that improves slip, softness, and spreadability in creams, lotions, makeup, and lip products. It can also reduce a greasy feel in oil-rich formulas.
Is Cetyl Lactate clean?
From a clean-beauty perspective, this ingredient is generally low-friction, with no major restricted-list profile and low irritation potential in typical leave-on use. Sensitivity is uncommon, but any ester can feel rich or occlusive for some acne-prone users depending on the full formula.
Is Cetyl Lactate sustainable?
This material is commonly made from a C16 fatty alcohol and lactic acid, which can come from plant, fermentation, or mixed supply chains depending on the supplier. It is expected to be biodegradable, while sourcing quality depends on whether the fatty alcohol feedstock is responsibly managed and traceable.
Is Cetyl Lactate COSMOS-approved?
It can fit COSMOS-natural formulations when the feedstocks and esterification process meet the standard’s criteria, so supplier documentation matters. Its Green Chemistry profile is favorable when made from renewable inputs through simple ester chemistry and when it shows ready biodegradability.
How does Cetyl Lactate work chemically?
The molecule is a long-chain fatty ester with both a lipophilic alkyl segment and a small it-derived polar segment, giving it good emollience with a lighter sensory profile than many heavy oils. It is typically used in the low single digits to around 10% in anhydrous and emulsion systems, and like many esters, it is most stable in mildly acidic to neutral formulas rather than strongly alkaline conditions.
