  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.
