Pharmaceutical & Cosmetic products

New thickener with high tolerance against salt. Its strength in resistance against multivalent ions and excellent thixotropic character enable a flexible formulation in functional cosmetics containing minerals and electrolytes. Saltolera creates an innovative gel with excellent dispersion of a water-soluble vitamin C derivative, which makes for an extraordinary smooth and fresh texture.

  • Resistant against multivalent ions and thixotropic
  • Smooth and silky texture
  • Fresh and cool feeling
Product name (abbreviation) Saltolera
INCI (International Cosmetic Ingredient name) Acrylic Acid/Perfluorohexylethyl Acrylate Crosspolymer

Stability against metal ions

In the existence of metal ions, the stability of other water soluble polymer thickeners decreases. This is presumably because the intramolecular repulsion stemming from the ionic charge of the polymer is weakened due to electrical shielding by excessive metal ions. Saltolera, on the other hand, can achieve the desired increase in viscosity by adding salt.

Stability against heat

Thickened liquid made with Saltolera is less likely to decrease viscosity when heated, and its viscosity does not change even if left for many hours at 40 °C.
