Calcium Lactate ●
TL;DR. This ingredient is used mainly as a humectant and skin-conditioning mineral salt, with secondary roles in buffering and supporting water-phase stability. In oral care or barrier-focused formulas, it can also serve as a source of calcium ions.
What does Calcium Lactate do in a cosmetic formula?
This ingredient is used mainly as a humectant and skin-conditioning mineral salt, with secondary roles in buffering and supporting water-phase stability. In oral care or barrier-focused formulas, it can also serve as a source of calcium ions.
Is Calcium Lactate clean?
From a clean-beauty perspective, this ingredient is generally well tolerated, not a common sensitizer, and does not sit on major restricted lists. Irritation risk is low at typical cosmetic use levels, though any mineral salt can feel drying or sting on compromised skin at higher concentrations.
Is Calcium Lactate sustainable?
This material is commonly made from a fermentation-derived hydroxy acid neutralized with a mineral calcium source. The organic portion is readily biodegradable, and it is not associated with persistence or bioaccumulation concerns.
Is Calcium Lactate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulation principles when made from permitted fermentation and mineral inputs. Its profile fits Green Chemistry well because it can use renewable feedstock, simple neutralization chemistry, water-based processing, and has a favorable biodegradation profile.
How does Calcium Lactate work chemically?
Chemically, this compound is an ionic salt made of a divalent calcium cation paired with two small alpha-hydroxy carboxylate counterions, which makes it water-soluble and oil-insoluble. It is typically used in low single-digit percentages, performs best in aqueous systems from mildly acidic to neutral pH, and can form insoluble complexes with phosphates, carbonates, or some strongly anionic materials.
