Have you ever wondering is the toothpaste you bought for your kid is safe for used? I am very concerned about this because after my survey, most toothpastes (including kids toothpastes)sold in our Malaysia's local super market consists of Sodium Lauryl Sulfate(SLS). SLS is an important foaming agent used in many personal care cleaning products, such as shampoo, body wash, soap, and mouth wash. Its relative, sodium laureth sulfate (SLES), is sometimes used as a replacement for SLS and claim for less irritating.
I have read from many articles(one of them is Journal of The American College of Toxicology, 1983 (http://www.natural-health-information-centre.com/sls-JACT-report.html)) and get to know the severe effect of SLS and SLES to skin and its toxic accumulation in our lungs, liver, heart and brain. It also causes mouth ulcers(my daughter has suffered from month ulcer very frequently last 2 years when she still used the SLS containing toothpaste).
Immediately, I think about what if our little toddler accidentally swallowed the toothpaste containing the SLS. SLS had an LD 50 (Lethal Dose for 50% of the animals tested) of 0.8 to 110 g/kg in rats. If you toddler weights 15kg, the lethal dose is 12g to 1650g of SLS. Although this is quite a high dose, I would rather choose to avoid toothpaste containing SLS.
I finally found a kids’ toothpaste without SLS in our local market, i.e. PUREEN KIDS TOOTHPASTE, introduced by a dentist when we brought our daughter to repair her 4 pieces of decayed tooth.
