The Basics On Sodium Laureth Sulfate

What is Sodium Laureth Sulfate?

Can be derived from coconut; it is used primarily as a detergent cleansing agent.

What is Sodium Laureth Sulfate used for?

Sodium Laureth Sulfate, also known as SLES, is an anionic surfactant. Its amphiphilic properties make it an ideal detergent. SLES is a very effective ingredient used in many skincare cleaning products as creams and lotions. Acting as a surfactant, it wets body surfaces, emulsifies or solubilize oils, and suspend soil. SLES contributes to foaming and lathering properties in cleansing products and bubble baths.Sodium laureth sulfate has been rated as a moderate hazard risk for use in skincare and cosmetic formulations. It can cause skin irritations for people with sensitive skin1.

Sodium Laureth Sulfate During Pregnancy

What we know about using Sodium Laureth Sulfate while pregnant or breastfeeding

Limited information available.

The CIR Expert Panel recognized that most of the acute oral toxicity, dermal irritation and sensitization, subchronic and chronic oral toxicity, reproductive and developmental toxicity, carcinogenicity, and photosensitization studies have been con ducted on ammonium laureth sulfate and sodium laureth sul fate. There are limited safety test data on most of the other ingredients included in this safety assessment. Sodium and ammonium laureth sulfate have not evoked adverse responses in any toxicological testing, including acute oral toxicity, subchronic and chronic oral toxicity, reproductive and develop mental toxicity, carcinogenicity, and photosensitization studies. These data, however, are considered a sufficient basis Robinson et a! 161S for concluding that the other ingredients are safe in the prac tices of use and concentration described in the safety assess ment because of the fundamental chemical similarities between them and because they all are chemically similar salts (salts are expected to be dissociated in any product formulation independent of whether the salt is sodium, ammonium, magne sium, or zinc) of sulfated ethoxylated alcohols, and they all function as surfactants in cosmetic formulations. Based on these considerations, safety test data on 1 ingredient may be extrapolated to all of them. The CIR Expert Panel also recognized that there are data gaps regarding use and concentration of these ingredients. However, the overall information available on the types of products in which these ingredients are used and at what con centrations indicates a pattern of use that was considered by the Expert Panel in assessing safety. (Were ingredients in this group not in current use to be used in the future, the expectation is that they would be used in product categories and at concen trations comparable with others in the group.) The panel noted that sodium laureth sulfate and ammonium laureth sulfate can produce eye and/or skin irritation in experi mental animals and in some human test subjects; irritation may occur in some users of cosmetic formulations containing these ingredients. The irritant effects, however, are similar to those produced by other detergents, and the severity of the irritation appears to increase directly with concentration.

General safety info about Sodium Laureth Sulfate from CIR

Sodium Iaureth sulfate is a member of a group of salts of sulfated ethoxylated alcohols, the safety of which was evaluated by the Cosmetic Ingredient Review (CIR) Expert Panel for use in cosmetics. Sodium and ammonium laureth sulfate have not evoked adverse responses in any toxicological testing. Sodium laureth sulfate was demonstrated to be a dermal and ocular irritant but not a sensitizer. The Expert Panel recognized that there are data gaps regarding use and concentration of these ingredients. However, the overall information available on the types of products in which these ingredients are used and at what concentrations indicates a pattern of use. The potential to produce irritation exists with these salts of sulfated ethoxylated alcohols, but in practice they are not regularly seen to be irritating because of the formulations in which they are used. These ingredients should be used only when they can be formulated to be nonirritating.

Use this, not that!
