Di-C12-13 Alkyl Tartrate ●
TL;DR. This ingredient is primarily an emollient and skin-conditioning ester, used to give formulas a smooth, cushiony feel and improve the spread of oils, pigments, or UV filters.
What does Di-C12-13 Alkyl Tartrate do in a cosmetic formula?
This ingredient is primarily an emollient and skin-conditioning ester, used to give formulas a smooth, cushiony feel and improve the spread of oils, pigments, or UV filters.
Is Di-C12-13 Alkyl Tartrate clean?
From a clean-beauty perspective, it is generally a low-irritation synthetic ester with little allergen concern and no major restricted-list profile. The main scrutiny is sourcing and processing transparency rather than routine skin tolerance.
Is Di-C12-13 Alkyl Tartrate sustainable?
This material can be made from mixed fatty alcohol feedstocks that may be plant-derived or petrochemical, so its sustainability profile depends on the supplier. Ester-type materials of this kind are typically more biodegradable than silicone or fluorinated film formers, but public biodegradation data for this exact material is limited.
Is Di-C12-13 Alkyl Tartrate COSMOS-approved?
COSMOS alignment is conditional, since it depends on whether the fatty alcohol portion and manufacturing route meet allowed natural-origin and esterification criteria. It fits Green Chemistry better when renewable feedstocks and efficient esterification are used, but petrochemical-origin grades would have weaker alignment.
How does Di-C12-13 Alkyl Tartrate work chemically?
The molecule is a diester formed from a four-carbon hydroxy dicarboxylic acid and mixed 12 to 13 carbon fatty alcohol chains, giving it oil solubility with some polarity. It is used in anhydrous and emulsion oil phases, is broadly compatible with esters, hydrocarbons, pigments, and many UV-filter systems, and is not typically selected for pH-driven performance.
