Waterproof Foundation with ReadyMix™ and Mixing ISO-Lite Fast with Ethyl Alcohol

Regarding your questions about formulating waterproof foundation using ReadyMix™ and mixing ISO-Lite Fast with Ethyl Alcohol:

ReadyMix™ in Oil-Based Foundation

ReadyMix™ colors, such as ReadyMix™ White (Polyglyceryl-2 Triisostearate Base) and ReadyMix™ White (Isononyl Isononanoate Base), are pigments (like Titanium Dioxide) dispersed in an oil base. As the staff correctly pointed out, oil and water do not mix. Therefore, when used in an oil-based foundation, the color from ReadyMix™ will not dissolve or run off when exposed to water or sweat.

Mixing ISO-Lite Fast and Ethyl Alcohol

ISO-Lite Fast (C11-12 Isoparaffin) is a type of hydrocarbon oil. Ethyl Alcohol (99.9%) is miscible with oil. This means that ISO-Lite Fast and Ethyl Alcohol can be mixed together to form a clear, homogeneous solution without the need for an emulsifier. The mixture will remain clear and non-viscous, consistent with the properties of both ingredients (ISO-Lite Fast is a light, fast-evaporating liquid, and Ethyl Alcohol is also a liquid solvent).

In summary, you do not need an emulsifier to blend ISO-Lite Fast and Ethyl Alcohol to achieve a clear, uniform mixture.
