Challenges of Water-Based SPF 60 Sunscreen

Question

Is it possible to formulate a sunscreen with SPF 60 PA+++ that has a clear, liquid, water-based texture?

Answer

Regarding your request for a water-based sunscreen formula with SPF 60 PA+++, achieving such a high SPF with a truly water-based, clear, liquid texture is generally challenging.

This is because water-soluble UV filters, which would be used in such a formulation, typically offer lower SPF and PA protection compared to oil-soluble or dispersed UV filters. High SPF formulations like SPF 60 usually require these more effective, often oil-based or dispersed, UV filters, which result in textures like emulsions, creams, or lotions, rather than clear liquids.

If a light, water-like texture is your priority, you might consider a formula with a lower SPF, or explore formulation techniques that can create a light texture using different types of UV filters.
