Magnesium Hydroxide Powder USP


Magnesium Hydroxide is used as an additive in formulations and acts as an absorbent or as a pH adjuster. It is a fine, white and odourless powder.

Magnesium Hydroxide is soluble in oil and slightly soluble in water.


  • Has effective oil-absorbent properties binding the oil on the skin and from inside the pore lining
  • Widely used as filler and texturizer
  • Can be used to neutralize acids (pH < 7.0) but reacts only slowly. Cannot increase the pH further in products with a pH > 7.0.
