Midnight Eclipse-Kaolin is silane surface treated kaolin designed to provide excellent SPF and PFA boosting properties when used in oil-in-water (O/W) sunscreens.

It enables a drastic reduction of organic UV absorber usage. Our sample formulation utilizing 10% Midnight Eclipse-Kaolin achieved SPF 42 and PFA 18 IN-VIVO, using only 6% organic UV absorbers (2% OMC, 2% Avobenzone, and 2% Octocrylene). Midnight Eclipse-Kaolin is designed to work best in more desirable O/W type sunscreen formulations.
