"The Myth about Sodium Laureth Sulfate (SLES)
Recently, a chain letter was circulated touting the dangers of a common cosmetic ingredient used in hair, bath and body products; sodium laureth sulfate. The chain letter was sent to e-mail addresses throughout the country and has received attention from consumers everywhere. As is typical of such ‘warnings’, the message was unsigned and fails to site any references to support its’ claims. In fact, upon further research, the chain letter has been traced to a host of ‘independent distributors’ for various multi–level marketing companies hawking “natural personal care products”
At L’anza Research International we are committed to informing our customers as to the carefully chosen ingredients used in our products. We are interested in maintaining the highest level of quality and education as to why we use specific ingredients.
We have been in the hair care profession for fifteen years and we are constantly working to enhance and improve the effectiveness of our hair care line. Therefore we would like to address the concerns surrounding sodium laurel sulfate in our products, as well as to provide resources for further information about this safe and effective ingredient.
What is sodium laureth sulfate?
Sodium laureth sulfate (correctly abbreviated SLES) is a common ingredient used in hair products, toothpaste, bath and shower gels. The chain letter confuses this compound with another, sodium lauryl sulfate, which is abbreviated “SLS”. The two substances are related but are not the same.
Why does L’anza use sodium laureth sulfate in its’ products?
Sodium laureth sulfate (SLES) is an effective cleaning agent (surfactant), which has been deemed safe by the FDA. SLES has been used for 40+ years is one of the most popular foaming/cleaning ingredients used in cosmetic products today. L’anza uses SLES at a barely detectable 2-3% concentration level in a couple of our shampoo formulations.
Is sodium laureth sulfate dangerous?
No, SLES is absolutely safe for infants, children and adults.
Is sodium laureth sulfate known to cause cancer?
No. The chemical does not appear on any official list of known or suspected carcinogens. All reputable chemists and public health institutions agree that sodium laureth sulfate does not pose a hazard when used in bath and body products.
How does an issue like this become so sensationalized?
There are several newly founded ‘natural’ cosmetic manufactures that use the Internet as a selling tool. This is an effective means of spreading unfounded claims to generate fear and increase sales. However, there is no official documentation that describes SLES as remotely harmful.

Assuming this is true, which I don't know, they still didn't explain why the addition. How did adding it to their formula make it better? I suspect it may be an attempt to create the product at a lesser expense to their company. What do you guys think? /images/graemlins/ohwell.gif
