Question
Based on the discussion about the differences between Oil in Water (O/W) and Water in Oil (W/O) emulsions, their properties (texture, washability, film formation), and suitability for different applications (general skincare vs. foundation/sunscreen needing water resistance), could you provide examples of emulsifiers that function as Oil in Water (O/W) binders?
Answer
Examples of Oil in Water (O/W) Emulsifiers
Based on the product descriptions, the following are examples of emulsifiers that function as Oil in Water (O/W) binders:
- Ceteareth-10: This is a non-ionic O/W emulsifier with an HLB of 12-13.
- C12-15 Pareth-12: Another non-ionic O/W emulsifier with an HLB of approximately 14.4. It can also function as a solubilizer.
- Beheneth-25: A non-ionic O/W emulsifier suitable for various cream, lotion, antiperspirant, deodorant, and sun care formulations.
- Steareth-10: Acts as an O/W emulsifier, co-emulsifier, dispersant, solubilizer, surfactant, and gelling agent in various cosmetic applications.
These emulsifiers help to create stable emulsions where oil droplets are dispersed in a continuous water phase, resulting in products that typically feel lighter and less greasy on the skin compared to Water in Oil (W/O) emulsions.
