Combining Natural Oil and Glycerin for Skin Nourishment

To combine Natural Oil and Glycerin in a skin nourishing formula, you will generally need an emulsifier, as oil and glycerin (which is water-soluble) do not naturally mix.

As suggested in the forum reply, if you use Double Glycerin (PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin), it may dissolve in the oil phase without needing an additional emulsifier, depending on the specific oil and concentration.

However, if you are using regular Glycerin, an emulsifier is necessary to create a stable mixture or emulsion.

Based on available information, several emulsifiers can be suitable for combining oil and a water-soluble component like glycerin. These often function as water-in-oil emulsifiers, helping to disperse the glycerin within the oil phase. Some options include:

• Oil Blender™ (Polyglyceryl-3 Diisostearate): This acts as a water-in-oil emulsifier and oil blender, suitable for combining various oils and potentially incorporating a small water phase like glycerin.
• Light Lotion Maker: An emulsifier that can create light-textured emulsions and can be used in a cold process.
• Polyglyceryl-10 Pentastearate: Used as a water-in-oil emulsifier.
• Polyglyceryl-4 Oleate: Also functions as a water-in-oil emulsifier.
• Polyglyceryl-2 Sesquioleate: Another water-in-oil emulsifier option.
• Polyglyceryl-4 Isostearate: Used as a water-in-oil emulsifier, particularly noted for water-drop formulations.

The best choice of emulsifier will depend on the desired texture, stability, and the specific ratio of oil to glycerin in your formula. It is recommended to test different emulsifiers to find the one that provides the best result for your specific application.
