Science
Mechanism of Action
This hydrolyzed casein derivative primarily functions by conditioning the skin, contributing to its overall well-being. Its bioactive peptide content is believed to impart additional physiological benefits, including potential antimicrobial properties and a reduction in facial pigmentation through the mitigation of Advanced Glycation End Products (AGEs) accumulation.

The Formula
Formulation
Stability
Stability is acutely pH-dependent. Casein's isoelectric point at approximately pH 4.6 signifies reduced stability, risking flocculation. Formulations should avoid pH below 3.0 due to a high risk of chain hydrolysis. Optimal conditions for deamidation are observed at pH 6.0, while maximum solubility for casein protein hydrolysates occurs at pH 10.0. Emulsion stability is maximized within the pH 6.0-8.0 range.
Safety
Safety Profile
Direct cosmetic safety assessments by CIR, SCCS, or FDA for STEARDIMONIUM HYDROXYPROPYL HYDROLYZED CASEIN are not available. However, a structurally similar compound, Hydroxypropyltrimonium Hydrolyzed Casein, is categorized with 'LOW' concern for allergies, immunotoxicity, and developmental/reproductive toxicity by EWG Skin Deep®.
