Dreads Hair and Scalp Health
If you're going to copypaste from somewhere, cite your references. If you do a search on your second and third sentences the exact text is from http://www.t3db.org/toxins/T3D3630
. The reference listed for that section of text is from "W625 - Organic Natural Health (1998). Cancer Causing Toxic Chemical Ingredients in Cosmetic and Skin Care Products. "
. No url to this source is provided and the information gathered from it is not correct, as shown in the first item below.1. "One dubious claim often made by the dozens of anti-SLS websites is that sodium lauryl sulfate is carcinogenic because it produces nitrosamines when it reacts with formaldehyde. Since neither compound contains a nitrogen atom, however, that is chemically impossible." (http://www.treehugger.com/files/2007/07/common_ecomyth_sls.php
)2. Industrial and lab chemicals are of very high purity. Even Chemicals that are harmless in low concentrations become poisonous to the body at these levels and need to be handled with care. SLS is not special.-SLS is an irritant and should not be inhaled. Thus respiratory protection is needed.-The official MSDS (material safety data sheet) lists splash goggles, lab coat, dust respirator, and gloves to be used. For protection in case of large spills, the MSDS lists splash goggles, full suit, dust respirator, boots, gloves, and self-contained breathing apparatus. (I'd say this is equivalent to a 'biohazard suit') [Section 8 http://www.sciencelab.com/xMSDS-Sodium_lauryl_sulfate-9925002
]-Large spills are not a commonplace and biohazard suits are not needed for normal handling.-The amount of SLS in shampoo is nowhere near the amount encountered in such workplaces and is not indicative of its danger in home use. Saying "those who work with SLS's must wear bio-hazard suits" is scary but irrelevant.But before this keeps going back and forth, this needs to be moved to the other thread. This is getting far off topic.Melanie Leontine said:
Sodium Lauryl Sulfate is a nitrosating agent. Once in the body, nitrosamines are activated by cytochrome P-450 enzymes. They are then believed to induce their carcinogenic effects by forming DNA adducts at the N- and O-atoms. Anything carcinogenic has the potential to produce cancer cells. SLS is listed as a poison and those who work with SLS's must wear bio-hazard suits. This doesn't sound like something I want to run into my scalp.
