This is my third and final Oprah Earth Day rant. On a recent show, Oprah’s guest featured a collection of products deemed Earth-friendly. One such product was made without Sodium Lauryl Sulfate. What was the beef with Sodium Lauryl Sulfate (SLS)? According to the guest, it disrupted hormones, and was used in products such as antifreeze.
This, in my opinion, was an extremely irresponsible, not to mention untrue, statement. SLS is in everything from shampoo to toothpaste. If it lathers or foams, SLS is probably in there. Is this due to a government plot to kill us all slowly, leaving corpses with inordinately clean hair? Not hardly.
SLS is derived from natural sources, such as coconut oil or palm oil, and SLS does not disrupt hormones. In fact, the Oprah show was the first time I have ever heard that it did. The allegation made against SLS is that it causes cancer. These rumors were spread via email in true urban legend fashion. In fact, Snopes.com has a section debunking the rumor. The American Cancer Society has also written an article debunking the myth.
SLS may cause skin irritation if you have sensitive skin, and if you are prone to mouth sores the SLS in toothpaste can exacerbate the problem. For most, however, SLS is a perfectly safe and gentle product.
If you do find that you are sensitive to SLS, many alternatives exist. For one, many of our handmade soaps do not contain SLS. As always, we are very careful to disclose the ingredients of our products; it is easy to choose products that suit your particular needs.
Another favorite ingredient we use provides deliciously thick foam and is known to be gentler than SLS. Sodium Lauryl Sulfoacetate is a free-flowing white powder that bubbles like nobody’s business. My kids love it, and it stands up to the ‘hair do’ test–when my daughter gives her baby brother a hair do, it doesn’t sting his eyes. 
So how do we navigate the constant barrage of products that are going to kill us, products that are going to save us, and the fact that these ‘findings’ seem to change on a daily basis? My personal opinion is that common sense, a careful assessment of facts, and just our own inner sense as mothers, fathers, or just people are what can serve us best. Most of the chemicals people are up at arms about have been used for decades. Most of us have used some of them our entire lives and have lived to tell the tale. Take a deep breath, relax, and make your decisions. The good news? There are always alternatives to any questionable product ingredient out there.
