DOWSIL(TM) 5225C Formulation Aid

• Provides an excellent delivery system for emollients, moisturizers, sunscreens, antiperspirant actives and pigments
• Gives stable water-in-silicone formulations
• Allows formulation flexibility
• Clear water-in-oil emulsion technology possible

• Delivery systems for both nonpolar and polar ingredients: nonpolar ingredients are dissolved in the external silicone phase and polar ingredients in the internal aqueous phase.
• Can be used in a wide range of personal care applications:
  • Color cosmetics
  • Skin care
  • Sun care
  • Antiperspirants and deodorants
  • Hair care

• Water-in-silicone emulsions can be easily prepared by slow addition of the aqueous phase to the oil phase using a variety of common mixing devices.
• The stability of the emulsions increases with the amount of shear used to form them.
• Since the aqueous phase is the internal phase of these emulsions, increasing the proportion of water will increase the viscosity of a given formulation.

1. Stir DOWSIL 5225C Formulation Aid thoroughly before use.
2. Add the water phase slowly to the oil phase using a high speed mixer.
3. Pass emulsion through a homogenizer (Silverson®, Colloid Mill, Ultra Turrax®) to stabilize the product further.
4. Electrolytes, preferably NaCl at a level of 1 to 2%, should be added to the water phase to ensure long term stability.
5. The emulsion can be made at ambient temperature if the formulation is free from solid ingredients.
