  • SiSiB® PC19591 can be used in a wide range of silicone personal care applications such as skin care, color cosmetics and sun care and so on.

  • How to use:

  • Slowly add the water phase into the oil phase, and then stir the mixture quickly till uniform.

  • Speeding up the stirring can improve the stability of the emulsion system.

  • Increasing the water proportion can improve silicone oil viscosity of the system.

  • Stir the oil and emulsifier thoroughly before adding water to emulsify.

  • If all the ingredients are liquid, emulsification can be operated at room temperature without homogenizer. Quick stirring can attain stable emulsion.

  • Adding some antifreeze agents such as propanediol and glycerin can improve the antifreeze effect of the finished product.

  • Recommend Dosage:

    The recommended usage level of this silicone transformer oil is 1%-5% when it’s used as major emulsifier, and 0.1%-1.5% as auxiliary emulsifier (according to the total amount of the formulation).
