  • Low-Friction Surfaces Prepared Using a Water-Soluble Amphiphilic Polymer and Its Application in Hair Cosmetics

抄録

<p>The thin-film structure and tribological properties of the dilute solution of a water-soluble amphiphilic polymer, bis-isobutyl polyethylene glycol (PEG)-14/amodimethicone (BIPA) copolymer, confined between mica surfaces were investigated using the surface forces apparatus (SFA). The results showed that BIPA molecules in the solution formed an adsorbed layer on each mica surface and friction between the adsorbed layers was extremely low; friction coefficient of the order of 10-5. This extremely low friction is originated from the fluid-like slippage of monomolecular layer of water confined between the adsorbed layers that constitute a flat and continuous slip plane. BIPA polymer was applied as an additive in hair cosmetics to improve the lubrication properties of human hair in wet condition. Damaged hair tends to tangle easily during shampooing, which is a common and stubborn hair trouble, mainly caused by the stiction between wet hair fibers. BIPA polymer completely suppressed stiction; the shampoo formulation including BIPA exhibited excellent detangling performance during washing.</p>
