Reducing Color Transfer from Sunscreen/Foundation with Film Formers

To reduce the problem of Iron Oxide transfer from sunscreen or foundation formulas onto face masks, ingredients that act as Film Formers can help. This group of ingredients creates a film coating on the skin, helping pigments adhere better to the skin and reducing transfer to other objects like face masks.

There are several types of Film Formers that can be used, depending on whether the formula is water-based or oil-based and the desired film properties. For sunscreen or foundation formulas containing Iron Oxide that require durability, reduced mask transfer, and ease of mixing, here are some interesting options:

• Comfort Film (Water Base): A water-based Film Former that provides a comfortable, non-sticky film texture. Suitable for skincare products requiring durability and can be used in makeup formulas. Helps the cream adhere better to the skin. Easy to mix in the water phase.
• Allianz OPT: A polymer Film Former that enhances water and wear resistance for long-lasting sun and color cosmetics formulas. It does not significantly increase formula viscosity, making it suitable for low-viscosity emulsions, spray sunscreens, or gels. It is a white sticky liquid dispersible in water, easy to mix in the water phase.
• Vinyl Film (Medium Wear, Soft) (VP/Hexadecene Copolymer): A Film Former that creates a waterproof film and helps formulas last longer. It also helps disperse pigments well in the formula. Suitable for makeup and sunscreen products. It is a liquid that dissolves in oil and can be mixed with the help of heat.

The choice of Film Former depends on the type of formula (Water-based or Oil-based) and the desired film properties. If the formula is water-based or an emulsion with a significant water phase, Comfort Film or Allianz OPT will be easier to mix.
