Compatibility of Dimethicone and Glycerin, and Use in Eyeshadow Formulation

Asked by: keepawfashion66 On: June 07, 2017 Product Type: Cosmetics

Question

Regarding the compatibility of ingredients, I understand that `Dimethicone` and `Glycerin` cannot dissolve directly into each other. Can they still be used together in the same formulation, and if so, how?

Additionally, can `Dimethicone` be used in eyeshadow formulations? If yes, what types of `Dimethicone` are suitable, and how should they be incorporated into the formula?

Answer

Mixing Dimethicone and Glycerin

Dimethicone and Glycerin do not dissolve directly into each other. However, they can be included in the same formulation by using an emulsifier to combine the oil/silicone phase (containing Dimethicone) with the water/glycerin phase.

Using Dimethicone in Eyeshadow

Yes, Dimethicone can be used in eyeshadow formulations. Dimethicone is a silicone fluid that helps to improve the texture and feel of cosmetic products, providing a smooth, slippery feel (slip skin feel) and helping to coat the skin. It is often used in oil-based or silicone-based formulas.

Products like Silicone Gel (High Gloss, Dimethicone Base) and Silicone Gel (High Matte, Dimethicone Base), which are based on Dimethicone, are specifically suitable for makeup formulas to improve texture, spreadability, and feel. While these gels are mentioned for lip products, the properties they provide are also beneficial in eyeshadows to help with application, blendability, and feel.

Various types of Dimethicone with different viscosities (e.g., Dimethicone (Light/50, Low-Odor), Dimethicone (Very Light/5, Low-Odor), etc.) can be used depending on the desired texture and feel of the eyeshadow product. They are typically mixed into the oil or silicone phase of the formula.
