Emulsifiers for High Silicone Oil Water-in-Oil Emulsion

Regarding your water-in-oil (W/O) emulsion formulation with a high oil/silicone phase (approximately 87%) and a low water phase (approximately 10%), silicone-based W/O emulsifiers are indeed the correct type to consider.

You asked about the suitability of PEG-10 Dimethicone and Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone based on product descriptions.

• Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone: Based on the product description available, this ingredient is described as a binder for water, oil, and silicone, suitable for W/O emulsions. However, the description specifically mentions that it is typically used in formulas with a water ratio in the range of 70-99% (meaning the oil/silicone proportion is 1-30%). Your formulation has a water phase of only about 10% (oil/silicone phase about 90%). Therefore, based strictly on the recommended usage range provided in the product description, this specific product appears not suitable for a W/O emulsion with such a high oil/silicone content.

• PEG-10 Dimethicone: A product with the exact name "PEG-10 Dimethicone" was not found in the database search. Therefore, I cannot confirm its suitability for your formulation based on product descriptions from the database.

For a W/O emulsion with a very high external oil/silicone phase like yours, you would typically need emulsifiers specifically designed for high internal phase emulsions (HIPE) or a combination of emulsifiers and stabilizers optimized for such systems. While silicone-based W/O emulsifiers are the right category, finding one explicitly recommended for a ~90% oil/silicone external phase is crucial.
