(last edited July 29, 2012) Organic ShampooALES can be derived from animal fats or from natural ingredients such as coconut oil. It is thought that the larger molecules found in ALES mean that it is less irritating to the skin than SLS based shampoos. The reason for this belief is that the larger molecules are less likely to permeate the skin than the smaller molecules found in Sodium Lauryl Sulfate.like thisShampoos that contain Ammonium Laureth Sulfate (ALES) are occasionally sold alongside sulfate free shampoo as an alternative to SLS and SLES products. While ALES continues to be a sulfate, selected companies point out the fact that this is a different sulfate from SLS or SLES. A lot of these producers point to a research performed by the Cosmetic Ingredient Review which identified ALES to be an effective cleansing agent and relatively safe when used discontinuously and after use followed by thorough rinsing of the hair and body. |
