Sodium Lauryl Sulphate (SLS) is found in most shampoos and
toothpaste. It is a known skin irritant and is absorbed through
the skin and retained in the heart, liver and brain for long
periods of time. It can cause damage to the eyes, even when
absorbed through the skin. Exposure can Lead to coughing,
headaches, nausea and vomiting. It is an ingredient of great
concern for scientists, especially when children are exposed to
it. Oddly, Skin Deep only rates this ingredient a 3. Sodium
Laureth Sulphate(SLES) is a milder version of SLS with an added
ether chain and is regularly found in cleansers and shampoos. It
is added to thicken and give a richer consistency. It can cause
skin irritation, and should be kept away from children. Ammonium
Lauryl Sulfate(ALS) is also commonly used in shampoos and
cleansers. It can irritate eyes, skin and lungs but is much
milder and safer than SLS. The Environmental Working Group's
Skin Deep Database rates this ingredient 1-2. Sodium Lauryl
Sulphoacetate(SLSA) sounds very similar
