Acetylglutamine

TL;DR. This ingredient is used mainly as a skin-conditioning and humectant agent, helping formulas support a smoother feel and water-binding performance. It can also appear in hair care for conditioning benefits.

What does Acetylglutamine do in a cosmetic formula?

This ingredient is used mainly as a skin-conditioning and humectant agent, helping formulas support a smoother feel and water-binding performance. It can also appear in hair care for conditioning benefits.

Is Acetylglutamine clean?

It is generally viewed as low concern in clean-beauty screening, with no major allergen or restricted-list profile. The main review point is supplier documentation, since origin and processing route can vary.

Is Acetylglutamine sustainable?

This material is typically made from an amino-acid feedstock followed by acetylation, so its sustainability profile depends on whether the starting material is fermentation-derived or petrochemical-linked. It is expected to be readily biodegradable and is not associated with environmental persistence concerns.

Is Acetylglutamine COSMOS-approved?

It can fit COSMOS-natural formulas when the supplier can document natural-origin feedstocks and a permitted processing route, while fully synthetic grades may not qualify. From a Green Chemistry view, it is favorable when made from fermentation-derived inputs using lower-residue processing.

How does Acetylglutamine work chemically?

The molecule is an acetylated amino-acid derivative with amide and carboxyl functionality, giving it good water compatibility and affinity for hydration-focused formulas. Typical use is often in low percentages, commonly around 0.1% to 2%, and it is best formulated in aqueous systems within a skin-compatible pH range.
