It’s a term that is becoming more popular.
There is valid reason for not including certain ingredients in personal care products.
But none more so than sulfates.
During the 1960s, a lot of these sulfate surfactants were brought to the attention of the government.
This is due to the environmental and health problems associated with using them.
Many were taken off the market and an emergence of new and innovative sulfate free shampoo formulas appeared.
For more information on this subject, you may find the article, “The Best Body Wash Ingredients“, useful.
SODIUM LAURYL SULFATE
This is a chemical compound often known by its abbreviated name, SLS.
This ingredient is often used for its corrosive properties and its ability to break down grease.
It is an ingredient that is commonly used as a detergent, and is found in many household and industrial products, such as floor cleaners and de-greasers for engines.
Surprising then, that it is also used in many cosmetic preparations, including shampoo products, body washes, and toothpaste.
Because it is very corrosive, SLS can strip the lipids from our skin; drying it out and breaking down the cellular membrane, allowing it to penetrate even further into our body.
These compounds then enter the bloodstream, and can build up over time in the internal organs such as the heart, lungs, and kidneys.
Alarmingly, according to a material data sheet written by the FDA, long-term exposure to SLS can cause headaches, eye damage, allergies, and nausea.
Clinical studies have found that SLS can actually mutate cell structure and DNA, in some cases causing cancer!
SODIUM LAURETH SULFATE
Label regulations allow companies to say that SLES is derived from coconut; unfortunately, this allows manufacturers to include the term “natural” in their labelling.
Sodium laureth sulfate is a cheap and readily available ingredient, which is why so many manufacturers love to use it in their product.
The fact that it is allowed to be labelled as natural, is completely misleading to the customer.
The manufacturing process that this ingredient has to go through involves a chemical reaction, where the end product – once a coconut-based structure – becomes part vegetable, part petroleum.
This process involves using ethylene oxide, which has been known to cause both kidney and liver damage.
Yes, there is the argument that using only minuscule amounts in formulas doesn’t cause long-term damage; nevertheless, I prefer to err on the side of caution and avoid the use of these controversial ingredients in our formulas.
After all, with so many other lovely sulfate free shampoo ingredients to get sudsy with, why wouldn’t I?
