Both are SLS and SLES are common ingredients, which create foam and bubbles, and are found in most shampoos, cleansers, shower gels and bubble baths. They are cosmetic detergents that degrease and remove oil from the hair and skin. As consumers, we expect our shampoos and cleansers to foam and so the manufacturers add these unnecessary ingredients simply to meet that expectation. Check the label of any of your existing products to see if they contain SLS or SLES ingredients.
SLS is considered a benchmark ingredient for irritancy and is used in patch test studies as a "Positive Control” substance of known irritancy.
“The ingredients have been shown to produce eye and/or skin irritation… irritation may occur in some users of cosmetic formulations containing the ingredients" the report continued. "The irritation effects are similar to those produced by detergents and the severity of irritation increases with concentration.”
Firstly, we are pleased that the irresponsible rumors have been addressed. Our concern is simply that these ingredients are too irritant for sensitive or reactive skin. We believe that SLS or SLES are best avoided given their extreme harshness. Besides, foam and bubbles are not necessary to clean.
