Viscosity (cSt, 25°C)
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.
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).
SiSiB® PC19591 is supplied in 20Kg plastic pail or 200Kg steel drum.
In the original unopened packaging, SiSiB®PC19591 has a shelf life of two years in a dry and cool place at room temperature.
