ImerCare Opaque

ImerCare® Opaque Your natural solution for a rich, creamy texture in gels and shampoos

  • High opacity and whiteness
  • Natural, eco-friendly
  • One-size-fits-all solution

ImerCare® Opaque is an eco-friendly solution opacifier that imparts opacity and whiteness to gel and shampoo formulations.

Most current opacifying solutions used in cosmetics are based on synthetic ingredients such as styrene/acrylate copolymers, which pose a potential threat to the environment and can be difficult to formulate.

ImerCare® Opaque is a 100% natural kaolin based solution which can be used to replace synthetic cosmetic opacifiers.

Compared to conventional kaolins, ImerCare® Opaque has an innovative particle shape which confers whiteness and a rich, creamy effect to gels and shampoos, giving them a luxurious, wholesome quality.

ImerCare® Opaque is:

  • Neither pH nor ionic-surfactant sensitive 
  • Non allergenic
  • Cold processable
  • A one-size-fits-all solution for a wide range of gels and shampoos 
  • Compliant with industry microbiological standards without the need for irradiation

ImerCare® Opaque can be used in all cosmetic formulations requiring opacity. The recommended loading level is 0.5 to 1 wt% to obtain equivalent opacity performance to oil-derived chemicals.
