Ingredients for Long-Lasting Makeup in Mineral Spray

Okay, based on your question about adding ingredients to a mineral spray to help makeup last longer, you are looking for film-forming ingredients. These ingredients create a thin, often invisible, layer on the skin that helps to hold makeup in place and improve its longevity and water resistance.

Here are some suitable water-based film-forming ingredients that can be used in a spray formula:

• Allianz OPT (Acrylates/C12-22 Alkyl Methacrylate Copolymer): This polymer film former is excellent for providing water and wear resistance in long-lasting cosmetic formulas, including sprays and gels. It does not significantly increase the viscosity, making it ideal for spray applications.
• Syntran 5778 and Syntran 5288: These are general water-dispersed film formers used in products requiring long-lasting and waterproof properties. They can contribute to the durability of makeup when included in a setting spray.
• Flex Film (Water Base): This provides a soft and moderately waterproof film texture, suitable for application on the skin. It can be used alone or combined with other film formers for enhanced effects.
• Gloss Film (Water/Alcohol Base): This creates a very durable and waterproof film. While it provides a glossy finish (which might be desired for a dewy look), it offers maximum longevity and water resistance.

You can experiment with these ingredients, starting with recommended usage rates, to find the best performance for your mineral spray formula.
