recently, I was horrified to discover that the Ammonium Lauryl Sulfate (ALS) I use for a surfactant in my shampoo uses formaldehyde as a preservative system. I believe in practicing responsible chemistry and I wish to formulate with preservative free ammonium lauryl sulfate.
Does anyone know if it possible to get preservative free ammonium lauryl sulfate? If yes, which vendor can provide this raw material?
if this is not possible does anyone know of a preservative free replacement for this surfactant?
