Mixing Glycerin and Oil (10:90 Ratio)

Regarding your question about mixing Glycerin with oil at a ratio of 10% Glycerin and 90% oil, it is not possible to create a stable, emulsified product with this composition.

Glycerin is a water-soluble ingredient and does not mix with oil. To combine oil and water-based ingredients into a stable product like a cream or lotion, an emulsifier is required to form an emulsion. However, a mixture that is predominantly oil (90%) with a small amount of a water-soluble ingredient like Glycerin (10%) is not a system that can be effectively emulsified using standard cosmetic emulsifiers.

Glycerin is typically incorporated into the water phase of a formulation. Attempting to blend 10% Glycerin directly into 90% oil will result in the two phases separating.

Therefore, achieving a stable mixture of 10% Glycerin and 90% oil for a cosmetic formulation is not feasible.
