TLDR Modern shampoos use a mix of surfactants and other ingredients to clean, reduce irritation, and improve performance.
Modern shampoos from 2011 contained a mix of anionic, amphoteric, and nonionic surfactants to achieve various functions such as cleaning, emulsifying, foaming, increasing viscosity, and reducing irritation. Anionic surfactants like SLES and SLS were primarily used for cleaning, while amphoteric surfactants like CAPB were added to reduce irritation and increase viscosity, making them suitable for mild formulations like baby shampoos. Nonionic surfactants such as CME and CDE served as foam boosters and viscosity builders. Additionally, ingredients like alkyl polyglucoside (APG) were favored for their low toxicity and environmental compatibility. Conditioning agents like polydimethylsiloxane (PDMS) and cationic water-soluble polymers were included to enhance conditioning effects. Other components such as chelating agents, pH adjusters, pearling agents, inorganic salts, oils, preservatives, antidandruff agents, and fragrances were also incorporated to improve the overall performance and appeal of the shampoos.
