Asparagine ●
TL;DR. This ingredient is primarily a skin-conditioning and humectant component, used to support water binding in the stratum corneum. It can also contribute to a softer feel in hair and skin formulas.
What does Asparagine do in a cosmetic formula?
This ingredient is primarily a skin-conditioning and humectant component, used to support water binding in the stratum corneum. It can also contribute to a softer feel in hair and skin formulas.
Is Asparagine clean?
From a clean beauty perspective, it is generally low-friction, well tolerated, and not a common listed allergen. It does not carry the restricted-list concerns associated with many preservatives, silicones, UV filters, or fragrance materials.
Is Asparagine sustainable?
This material is commonly produced by fermentation or protein hydrolysis, with a relatively favorable sourcing profile when made from plant or biotech feedstocks. It is water soluble and expected to biodegrade readily, with low concern for environmental persistence.
Is Asparagine COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when sourced through allowed natural, fermentation, or approved processing routes, with supplier documentation confirming compliance. Its Green Chemistry profile is strong because it is biodegradable, useful at low levels, and can be made from renewable feedstocks.
How does Asparagine work chemically?
The molecule is a polar, proteinogenic amino acid with both amino and carboxyl functionality plus a neutral amide side chain, giving it strong water-phase compatibility. It is typically used at low levels, often below 1%, and is most stable in mildly acidic to neutral formulas, while high heat or alkaline conditions can promote gradual deamidation.
