[1] [2] Other proponents avoid shampoos because they believe some of the ingredients to be harmful. Sulfates like sodium lauryl sulfate can be irritants; [9] [10] sulfate-free shampoos are also marketed based on this concern. [11] There are also pollution concerns with the fungicides in dandruff shampoo. [12] [13]
Sodium laureth sulfate (SLES), an accepted contraction of sodium lauryl ether sulfate, also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent. [1]
Conventional shampoos often contain harsh detergents such as sodium lauryl sulfate (SLS) and ammonium lauryl sulfate (ALS). These detergents strip the hair of its natural oils and cause damage to ...
Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water. The sulfate ingredient acts as a surfactant, trapping oils and other contaminants, similarly to soap. Shampoos are marketed to people with hair.
As a result, the Food and Drug Administration plans to propose a ban on formaldehyde (FA) and other FA-releasing chemicals as an ingredient in hair smoothing and hair straightening products ...
This sparked great interest in the development of synthetic detergents that biodegrade into environmentally friendly byproducts. Such interest has led to the development of the linear carbon chain compounds commonly used today, such as sodium lauryl sulfate and sodium laureth sulfate/ sodium lauryl ether sulfate (SLS/SLES).

‘Best solution is to simply not use these products,’ scientists say
Sodium lauroyl sarcosinate , also known as sarcosyl, is an anionic surfactant derived from sarcosine used as a foaming and cleansing agent in shampoo, shaving foam, toothpaste, and foam wash products. [1] This surfactant is amphiphilic due to the hydrophobic 12-carbon chain and the hydrophilic carboxylate.
