Sodium Laureth Sulfate (SLES) is a common cleansing agent in the cosmetics industry, known for its ability to produce foam. It can be derived from coconut or synthesized. It is a surfactant, i.e. a cleansing agent that can be aggressive to dry, sensitive skin.

Properties and uses
SLES is commonly used in facial cleansers, shower gels and shampoos for its effective cleansing and foaming properties.

Security
Thanks to its ability to modify molecule tension, SLES is effective at breaking down and removing fatty molecules. It has a lipophilic head, which binds to grease, and a hydrophilic head, which binds to water. This duality ensures optimum cleaning action during rinsing.

Effects on the skin
Despite its effectiveness as a detergent, SLES can be harsh on dry, sensitive skin. It causes a significant loss of moisture, far more than other milder cleansing bases. Regular use without care can lead to skin irritation.

Clarifications on Common Confusions
Despite frequent confusion, Sodium Laureth Sulfate is different from Sodium Lauryl Sulfate, which is more irritating.

Physical aspect
In its raw state, SLES appears as a slightly cloudy or clear solution. It is a very common ingredient in cleaning products, responsible for bubble formation.

Sodium Laureth Sulfate is a key ingredient in many cosmetic products, appreciated for its cleansing and foaming properties, especially for those with combination to oily skin.
