Ascorbyl Palminate ●
TL;DR. This ingredient is primarily an oil-phase antioxidant, used to slow rancidity in oils, butters, and emulsions. It can also support antioxidant positioning in skin-care formulas, though its main formulation role is product protection.
What does Ascorbyl Palminate do in a cosmetic formula?
This ingredient is primarily an oil-phase antioxidant, used to slow rancidity in oils, butters, and emulsions. It can also support antioxidant positioning in skin-care formulas, though its main formulation role is product protection.
Is Ascorbyl Palminate clean?
From a clean-beauty perspective, it is generally well accepted, low in irritation potential, and not a common allergen or major restricted-list concern. The main watchpoint is quality control around sourcing and residual processing materials, rather than the molecule itself.
Is Ascorbyl Palminate sustainable?
This material is commonly made from a fermentation-derived antioxidant acid and a C16 fatty-acid feedstock that may be plant-derived, often with palm supply-chain relevance. It is expected to be biodegradable and is not known for environmental persistence.
Is Ascorbyl Palminate COSMOS-approved?
It is generally permitted under COSMOS natural and organic frameworks when the feedstocks and processing route meet standard requirements. Its fit with Green Chemistry is good overall because it can be made from renewable inputs, is used at low levels, and has a favorable biodegradability profile.
How does Ascorbyl Palminate work chemically?
Chemically, it is an amphiphilic, lipid-soluble ester with a reducing lactone head and a C16 alkyl tail, which helps it partition into oil phases and oil-water interfaces. Typical use is about 0.01 to 0.2% for antioxidant protection and sometimes higher in skin-care formulas, with stability improved versus the parent water-soluble antioxidant but still limited by heat, light, oxygen, and higher pH.
