TLDR PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.
The study investigated the formation of nanoparticles using a random copolymer of 2-methacryloyloxyethyl phosphorylcholine (MPC) and stearyl methacrylate (SMA), known as PMS (Polyquaternium-61), for hair treatment. By diluting PMS in a polyhydric alcohol solution with hot water, nanoparticles with an average size of less than 50 nm were produced. When damaged hair was treated with cationized PMS nanoparticles, X-ray photoelectron analysis confirmed uniform adsorption on the hair surface. Additionally, fluorescence microscopy showed that PMS penetrated and adsorbed not only on the surface but also inside the hair. The treatment also demonstrated effects such as re-hydrophobization of damaged hair surfaces, prevention of cuticle lifting, reduction of surface friction, antistatic properties, and color fading prevention.
