Price of transparent white mineral oil #15 food grade How to use: Because it have special and excellent physical and chemical function, it can be used in many different industries: 1. Cosmetic industry for skin care cream, bath gel, shampoo and other cosmetic formulations with excellent softness and silky feel. 2. Rubber, plastic, latex, polyurethane, light industry: as a model release agent, brightener agent and release agent Dosage: Depending on the application conditions, the concentration is from a few PPM up to 100% range. Note: With a high concentration of acid or alkali substances and Lewis acid has a tendency to degrade volatile exposure, the higher the temperature of the reaction is more obvious. Low concentration in contact with strong acid or alkali at high temperatures or prolonged action of the viscosity tends to become larger until cross -linked.
