Why are potential carcinogens found in liquid soap?

sodium laureth sulphate

Answer:
Sodium laureth sulphate is not a carcinogen. However, during the manufacture of this chemical, (which makes the soap foam and helps dissolve grease and oils) contaminants are introduced. These contaminants are potential carcinogens. But, they are at such low amounts, that the average person would need to be exposed to the soap constantly for 100's of years in order to get cancer.
Consequently, IF there are carcinogens in soap, they are so dilute as to be virtually nonhazardous. As an analogy, radiation is a carcinogen, but you get x-rays from the doctor. The dose is small enough to be considered safe. In fact, you absorb small amounts of radiation on a daily basis.
Sodium laureth sulfate is not a carcinogen, it is a detergent.
There are some consernss regarding liquid soap with germ killing properties, that they will cause germs to become stronger and immune to the antiseptics available.
