CALCIUM STEARATE

TL;DR. This ingredient is a hydrophobic texture aid used to improve slip, binding, opacity, and anti-caking performance in powders, sticks, and anhydrous formulas. It can also help thicken oil phases and improve water resistance in some formats.

What does CALCIUM STEARATE do in a cosmetic formula?

This ingredient is a hydrophobic texture aid used to improve slip, binding, opacity, and anti-caking performance in powders, sticks, and anhydrous formulas. It can also help thicken oil phases and improve water resistance in some formats.

Is CALCIUM STEARATE clean?

Clean-beauty frameworks generally view it as low concern because it is not a fragrance allergen, preservative, or high-sensitization material. The main quality questions are feedstock origin and trace impurities from industrial-grade material.

Is CALCIUM STEARATE sustainable?

This material is commonly made from long-chain fatty acid feedstocks plus mineral inputs, and the fatty portion may be plant, animal, or mixed-source depending on the supplier. It is expected to biodegrade, but vegetable supply chains may involve palm-derived inputs unless sourcing is specified.

Is CALCIUM STEARATE COSMOS-approved?

It is generally compatible with COSMOS-natural and COSMOS-organic formulations when produced from permitted natural-origin fatty acid and mineral inputs. From a Green Chemistry view, it fits reasonably well because it can be made by simple neutralization or soap-forming chemistry with low solvent burden and good biodegradability.

How does CALCIUM STEARATE work chemically?

Chemically, it is an alkaline-earth metal carboxylate with two C18 saturated fatty-acid carboxylate chains associated with one divalent metal ion, giving a waxy, water-insoluble, hydrophobic solid. Typical use is often below 1 to 5% as a texture, anti-caking, or binding aid, with higher levels possible in powders and sticks, and it is stable under normal cosmetic conditions but can be disrupted by strong acids or strong chelators.
