GABA ●
TL;DR. It is used as a skin-conditioning and humectant active, usually positioned for smoothing and comfort in leave-on formulas. Its role is not preservation, cleansing, UV filtering, or emulsification.
What does GABA do in a cosmetic formula?
It is used as a skin-conditioning and humectant active, usually positioned for smoothing and comfort in leave-on formulas. Its role is not preservation, cleansing, UV filtering, or emulsification.
Is GABA clean?
It has a low irritation and sensitization profile and is not a common clean-standard restricted-list ingredient. The main clean-beauty caveat is claims discipline, since topical wrinkle-relaxation claims are often stronger than the clinical evidence.
Is GABA sustainable?
It can be made by fermentation from carbohydrate feedstocks or by synthetic routes, with fermentation-derived grades aligning better with renewable sourcing. It is water soluble and expected to be readily biodegradable, with low concern for persistence or bioaccumulation.
Is GABA COSMOS-approved?
It can be compatible with COSMOS-natural or COSMOS-organic when produced from allowed natural or fermentation feedstocks and processed with permitted methods, while fully synthetic grades may not qualify. From a Green Chemistry view, it scores best when fermentation-derived, water-processed, and biodegradable.
How does GABA work chemically?
The molecule is a small zwitterionic amino-acid-type compound with high water solubility, so it fits best in the aqueous phase of serums, gels, toners, and creams. Typical cosmetic use is often around 0.1% to 2%, with good compatibility in mildly acidic to neutral formulas and limited oil-phase solubility.
