Transition Metal-Induced Oxidation: Implications for Skin Care Products

Transition metals in the skin affect the skin's pro-oxidation response to external stresses, well-known antioxidants and common chelating agents. The chemistry of transition metal-induced oxidation has implications for the development of skin care product

Refractive Index Matching: Principles and Cosmetic Applications

Clear emulsion formulas can be achieved by matching refractive indexes (RI) of water phase and oil phase. The match is achieved by varying the ratio of water and glycols, as show in several skin and hair care formulas.

Low-Energy Emulsification: Beyond Energy Conversation

The quality of emulsions manufactured with low-energy emulsification can be equal or even superior to the same emulsions made by a conventional hot process if conditions are optimized.
