Waterproofing Agents in Mascara: Can Aculyn 33 be used?

For making waterproof mascara, the main ingredient that provides waterproofing is a group of substances called Film Formers. These substances create a film coating on the eyelashes, making them resistant to water and moisture.

Based on the information found, several Film Formers are used in eye products and mascaras, including:

• Resist Film (Styrene/Acrylates Copolymer): This product is explicitly stated to create a strong film with high waterproof performance, suitable for mascara formulas.
• Polyacrylate-21: This is a water-based Film Former commonly used in mascara, providing gloss and flexibility, which helps with wear resistance.
• Allianz OPT (Acrylates/C12-22 Alkyl Methacrylate Copolymer): This is an Acrylates Copolymer polymer that helps create a film, offering water and long-lasting wear resistance.

Regarding the question of whether Aculyn 33 (Acrylates copolymer) can be used for waterproofing in mascara, Aculyn 33 is a type of Acrylates copolymer, but it is generally used as a thickener or stabilizer in water-based formulas. It is not primarily designed to form a film for waterproofing like the other Film Formers mentioned above. Therefore, if you specifically need waterproofing properties in mascara, it is better to use a Film Former specifically designed to create a waterproof film, such as Resist Film or Polyacrylate-21.
