Specific gravity



  • It's used as a part of oil phase and recommended to heat when using. Usually using with small amount of soluble oil when heating, to prevent crystallizing separation when cooling. If crystallizing happens, the viscosity will increase abnormally when placed at room temperature, even causing demulsification at worst situation. Compatible oil can be added to oil soluble silicone wax to solve this problem, with recommended proportion, silicone wax: oil=10:1~5.

  • Usage:  0.1-20%

  • To replace mineral oil or Vaseline recommended dosage less than 5%.
