Waterproof Sunscreen Formulation using Water-in-Oil Emulsifiers

MySkinRecipes offers ingredients that can be used to create sweat-resistant and waterproof sunscreens. This is primarily achieved through the use of Water-in-Oil emulsion technology, which provides excellent water resistance.

Key ingredients you can use include:

• Water-in-Oil EZ or Water-Capsule: These are Water-in-Oil emulsifiers that help bind water and oil together, resulting in a waterproof formula. The choice depends on the oil phase percentage in your formula (Water-in-Oil EZ for formulas with over 20% oil, Water-Capsule for formulas with less than 20% oil).
• SPF Protect Ultra: A sunscreen agent that provides high SPF and broad-spectrum protection against both UVA and UVB rays. It is highly stable and can be used in Water-in-Oil sunscreen formulations.

Additionally, other ingredients used in example formulas include LipidSoft Lite (a light emollient for easy spreading), Satin Cream Maker (helps create a gel texture in the water phase), Phenoxyethanol SA (preservative), and Purified Water.

If you are looking for a tinted sunscreen or a BB/CC Cream type, you can add Mica Powder or Sericite Powder for skin coverage.

Here are example waterproof sunscreen formulations from MySkinRecipes:
