Lactate ●
TL;DR. This ingredient is primarily used as a humectant and pH buffer, helping formulas hold water while supporting the skin’s natural moisturizing factor profile. It can also contribute mild smoothing in lower-pH systems.
What does Lactate do in a cosmetic formula?
This ingredient is primarily used as a humectant and pH buffer, helping formulas hold water while supporting the skin’s natural moisturizing factor profile. It can also contribute mild smoothing in lower-pH systems.
Is Lactate clean?
It is generally well accepted in clean-beauty frameworks, with no major restricted-list issues. Irritation potential is usually low at humectant or buffering levels, though stinging can increase in low-pH or higher-level formulas.
Is Lactate sustainable?
This material is commonly produced by fermentation of plant-derived sugars and is readily biodegradable. Its sustainability profile is generally favorable, with the main variables being feedstock choice and manufacturing energy.
Is Lactate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when made through allowed processes and paired with compliant counterions where relevant. It fits Green Chemistry principles well because it can come from renewable fermentation, biodegrades readily, and does not require high-concern solvents in typical production.
How does Lactate work chemically?
The molecule is a small alpha-hydroxy carboxylate that is highly water soluble and hygroscopic, which explains its humectant and buffering behavior. Typical cosmetic use is around 0.5 to 5% for hydration support, with performance and skin feel influenced by pH, electrolyte load, and the acid-base balance of the formula.
