research The adsorption behavior of cationic surfactant onto human hair fibers 42 citations , January 2009 in “Colloids and Surfaces B: Biointerfaces” A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.
research Effect of a non-ionic surfactant on skin-retention of cationic minoxidil microparticles suspended in an anionic surfactant solution 2 citations , November 2009 in “Korean journal of chemical engineering” Adding Brij 78 to minoxidil microparticles in a certain solution helps them stick to the skin better and prevents clumping.
research Influence of anionic surfactants on coacervation with cationic guar gum for hair care applications September 2025 in “International Journal of Cosmetic Science” A balanced mix of cationic guar gum and anionic surfactants improves hair conditioning and protection.
research Novel amino acid‐based surfactant for silicone emulsification and its application in hair care products: a promising alternative to quaternary ammonium cationic surfactants 12 citations , July 2017 in “International Journal of Cosmetic Science” N‐AOHPA is a promising alternative to traditional surfactants for better hair conditioning.
research Marangoni effect in the water wetting of surfactant coated human hair fibers 10 citations , November 1984 in “Journal of Colloid and Interface Science” The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
