Usage
Dissolution/dispersion:
Usually needs to be pre-mixed with low viscosity silicone oil (such as cyclopentasiloxane, D5) or other solvents to help evenly disperse.
Can be heated to 40-50°C to accelerate dissolution (adjusted according to the specific product properties).
Addition stage:
Add in the oil phase and mix evenly with other silicone oils or greases.
If it is a water-based formula, it needs to be matched with an emulsifier (such as PEG-10 polydimethylsiloxane).
Precautions:
Avoid direct mixing with highly polar ingredients (such as high concentration alcohol, strong acid/base), which may cause precipitation.
Test compatibility with other ingredients in the formula (such as sunscreen, pigment).
