Pharmaceutical & Cosmetic products

HIVISWAKO is a highly safe water-soluble polymer compound conforming to ‘carboxyl vinyl polymer’, which is listed at ‘Japanese Standards of Quasi-drug Ingredients’. Having a high affinity for water, alcohol, and glycol, it can be dispersed within these solvents. Even in low concentrations one can observe a thixotropic gelling high viscosity body with good transparency and a high yield value. HIVISWAKO shows superior performance when compared to the other natural or synthetic water-soluble polymers in terms of thickening, dispersion stability, aging resistance and resistance to bacteria. We offer three types of HIVISWAKO: 103, 104 and 105, which are designed for various purposes of thickening, dispersion, emulsifying and so on.

Product name (abbreviation) HIVISWAKO MD
Chemical name Carboxylvinylpolymer
INCI (International Cosmetic Ingredient name) CARBOMER

type

HIVISWAKO 103 MD ①the type with the largest thickening effect depending on the additive amount
②suitable for the use in need of high viscous and hard gels
HIVISWAKO 104 MD ①With the intermediate characteristics between 103 and 105 type, it can produce gel with good transparency.
②suitable to make gels for cosmetics and pharmaceutical products
HIVISWAKO 105 MD ①Viscosity is not effected by concentration. Designed to make gel or dispersion liquids with a relatively low viscosity and excellent transparency.
②With a wide effective pH range, the stability in the presence of metallic ions and the availability to compound multi-products, as above this is the type having the widest application range.
