Recently the Honest Company was accused of using Sodium Lauryl Sulfate (SLS) in their detergent. SLS may cause endocrine disruption or even cancer. I reached out and asked the Honest Company about the accusations. They said their products contain SCS, a gentler form of SLS that is coconut based. They said they have a study showing this. I asked to see the study. They would not provide it. I have been researching alternative detergents and cleaning products. I came across this site. I have not tried the products yet, but I am going to.
