Lactic Acid \ Certified Organic ●
TL;DR. This ingredient primarily adjusts pH and also functions as a water-soluble exfoliating acid in skin care. It can support smoother-feeling skin by loosening surface-cell cohesion when used at an appropriately low pH.
What does Lactic Acid \ Certified Organic do in a cosmetic formula?
This ingredient primarily adjusts pH and also functions as a water-soluble exfoliating acid in skin care. It can support smoother-feeling skin by loosening surface-cell cohesion when used at an appropriately low pH.
Is Lactic Acid \ Certified Organic clean?
From a clean-beauty perspective, this ingredient is widely accepted and not a typical restricted-list concern. The main consideration is use level and finished-formula pH, since strong acid systems can sting or irritate sensitive skin.
Is Lactic Acid \ Certified Organic sustainable?
This material is commonly made by fermentation of renewable plant sugars, including it-it feedstocks when specified. It is readily biodegradable and does not raise the same persistence concerns as many synthetic film-formers or silicones.
Is Lactic Acid \ Certified Organic COSMOS-approved?
It is permitted in COSMOS-natural formulas and can fit COSMOS-it formulas when the grade and sourcing meet the relevant certification requirements. It aligns well with Green Chemistry principles when fermentation-derived, using renewable feedstocks and producing a biodegradable, low-residue material.
How does Lactic Acid \ Certified Organic work chemically?
The molecule is a small three-carbon hydroxy carboxylic acid, water-miscible and chiral, with a pKa around 3.86, so its free-acid fraction increases as formula pH decreases. It is often used around 0.1 to 1% for pH adjustment and higher, commonly about 2 to 10%, in exfoliating products, where buffering and final pH drive skin feel and tolerance.
