Sodiumlactate ●
TL;DR. This ingredient is primarily a humectant and moisture-regulating agent, helping bind water in skin and hair products. It can also support pH control and mild buffering in aqueous formulas.
What does Sodiumlactate do in a cosmetic formula?
This ingredient is primarily a humectant and moisture-regulating agent, helping bind water in skin and hair products. It can also support pH control and mild buffering in aqueous formulas.
Is Sodiumlactate clean?
From a clean-beauty perspective, it is generally well-tolerated and does not sit on major restricted lists. At higher levels, it may cause temporary stinging on very sensitive or freshly exfoliated skin because of its water-active, acidic-salt chemistry.
Is Sodiumlactate sustainable?
This material is commonly made through fermentation of plant-derived sugars followed by neutralization, so it can have a renewable feedstock profile. It is readily biodegradable and is not associated with environmental persistence concerns.
Is Sodiumlactate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when produced from approved inputs and processing methods. Its fermentation route, water compatibility, biodegradability, and low residue profile fit well with Green Chemistry principles.
How does Sodiumlactate work chemically?
The molecule is a small, water-soluble organic salt with one hydroxyl group and one carboxylate group, giving it strong water-binding behavior. It is often used around 0.5% to 5% as a humectant, is stable across normal cosmetic pH ranges, and can add electrolyte load that may thin some polymer-thickened gels.
