A new laboratory in vitro method for the measurement of sunscreen water resistance uses
spectrophotometric analysis of a model skin substitute before and after 80-minute …

The aim of the study was to develop a simple reproducible and reliable in vitro water
resistance (WR) method to assess the sun care products. This paper is the result of a …

Water resistance of sun protection products has been found to be best determined by the
following methods:(1) Tests for determining UVL filter adherence to merino wool; this gives a …

The water resistance of 10 sunscreen products and three day‐care products containing
ultraviolet filters has been assessed using an in vitro method based on transmission …

Background/purpose: Sunscreen products today represent a trend of providing not only
simple sun protection factor (SPF)/protection of UVA (PFA) but also other additional benefits …

Objectives The water resistance of sunscreen products has taken more importance for the
UV protection of consumers involved in water activities and sports. The present work …

A novel ex vivo technique has been used to assess the sand/rub resistance of topical
sunscreens. The technique is based on transmission spectrometry using excised human …

The aim of this work was to develop an in vitro method for testing the water resistance of sun
products. For comparison, we used the in vivo method put forward by the Colipa. Standards …

This study shows the influence of a water‐in‐oil emulsion and an oil‐in‐water emulsion on
