Science
Mechanism of Action
Derived from green tea, PALMITOYL CAMELLIA SINENSIS EXTRACT operates through a multifaceted action. It acts as a potent antioxidant, neutralizing free radicals and mitigating inflammatory processes to protect skin and promote renewal. Its catechin content, including EGCG, confers significant anti-inflammatory and antimicrobial properties, beneficial for sensitive, rosacea, and acne-prone skin. Catechins also help inhibit DNA damage and activate repair enzymes, offering protection against environmental stressors like UV radiation. The palmitoylated form is specifically designed to enhance cellular respiration, re-oxygenate the skin, boost collagen synthesis, and provide defense against pollution, contributing to overall anti-aging effects. It further aids in soothing dry skin, reducing scaling, and improving elasticity and hydration.

The Formula
Formulation
Stability
The active catechins within green tea extract are highly susceptible to degradation by light and oxygen. Palmitoylation aims to significantly enhance both the stability and oil solubility of these compounds. Catechins also exhibit pH sensitivity, undergoing epimerization and degradation at pH 6 and above, with degradation accelerating notably beyond pH 9. While a specific optimal pH range for PALMITOYL CAMELLIA SINENSIS EXTRACT is not detailed, aqueous green tea extracts are typically stable below pH 5.0, suggesting a preference for acidic formulations.
Safety
Safety Profile
The CIR Expert Panel considers Camellia sinensis leaf-derived ingredients, including this palmitoylated form, safe for use when formulated to be non-sensitizing. Specifically, the parent Camellia sinensis leaf extract is deemed safe up to 0.86% in leave-on products and 1% in rinse-off products. Palmitoylated Green Tea Catechins (Oil Soluble Green Tea Extract) hold a 'Generally Recognized as Safe' (GRAS) status by the FDA for use as an antioxidant in food, further supporting its safety profile. No specific SCCS status has been identified for PALMITOYL CAMELLIA SINENSIS EXTRACT.
