PROPERTIES
Versatile film-formers for formulating of hair styling products. Properties and differentiation are determined by the VP/VAratio in the polymer. The series includes alcoholic (Ethanol, Isopropanol), aqueous and powder products.
• Medium to strong hold; Nonionic, no neutralization required
• Water-soluble or dispersable; Easy to wash out
• Non-forming; Easy to handle; Easy to comb out
• Compatible with ionic (anionic as well as cationic) additives
• Makes the hair shiny; Propane/butane compatibility 20-45%
• DME compatibility>70%
APPLICATIONS
All important hair styling applications, such as aerosol sprays, pump sprays, setting lotions, mousses and gels.Use of copolymers with different VP/VAratios allows formulator great flexibility:
• 37E;37I foranhydrousaerosolandpumphairsprayswithgoodhumidityresistance.
• 55E;55I forhydroalcoholicsettinglotionsandhairthickeners.
73W for styling, wet look gel and for water-based aerosol mousses.
64W; 73W, allow formulation of alcohol-free products.
For products where lower tack and better curl retention are desired, Sunlydone VAcopolymers are particularly suitable.
