HIVISWAKO MD (Carboxyl vinyl polymer, Carbomer)

Characteristics

superior performance thickeningsuperior performance dispersion stability

HIVISWAKO is a highly safe water-soluble polymer compound comforming to 'carboxyl vinyl polymer', which is listed at 'Japanese Standards of Quasi-drug Ingredients' and 'Japanese Pharmaceutical Excipients'. Having a high affinity for water, alcohol and glycol, it can be dispersed with these solvents. Even in low concentrations one can observe a thixotropic gelling high viscosity body with a good transparency and a high yield value. HIVISWAKO has an superior performance 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 103, 104 and 105 fitted for various purposes of thickening, dispersion, emulsifying and so on.

Application

type

HIVISWAKO 103 MD
  1. the type with the largest thickening effect depending on the additive amount
  2. suitable for the use in need of high viscous and hard gels
HIVISWAKO 104 MD
  1. With the intermediate characteristics between 103 and 105 type, it can produce the gel with good transparency.
  2. suitable to make gels for cosmetics and pharmaceutical products
HIVISWAKO 105 MD
  1. Even by increasing the amount added, its viscosity won't be extremely high and it can make the gel or dispersion liquid with a relatively low viscosity and excellent transparency.
  2. With a wide effective pH range, the stability to the metallic ion and the availablity to compound multi-products, as above this is the type having the widest application range.
