The effectiveness of lactates as moisturizers in rinse-off products is not commonly known. The effects are clearly shown in clinical tests with a base cleanser in which different levels of sodium lactate were used
This cleanser was applied on the face and rinsed off with water after 30 seconds. In time, the hydration of the skin was measured. This test clearly shows that adding 3-5% PURASAL S/60 increased skin moisturization for up to 4 hours after use.
Another clinical test (same set-up) was performed to compare commonly used moisturizers with lactates. Frequently used moisturizers are glycerin, sorbitol and sodium-PCA. The test proved both that sodium and calcium lactate are comparable to glycerin and are better than sorbitol and sodium-PCA.
