O SLES em cosméticos pode causar irritação?
In recent years, the cosmetic industry has witnessed a surge in consumer awareness regarding the ingredients used in personal care products. One such ingredient that has been under the spotlight is Sodium Laureth Sulfate (SLES). As a leading supplier of cosmetic raw materials, Zhengzhou Mahaco Industrial Co.,Ltd (MAHACO) is committed to providing transparent information about the safety and efficacy of SLES in cosmetics. This article delves into whether SLES can cause irritation, explores its uses, and highlights industry trends shaping the future of cosmetic formulations.
What is SLES and Why is it Used in Cosmetics?
Sodium Laureth Sulfate (SLES) is an anionic surfactant commonly found in shampoos, facial cleansers, body washes, and other personal care products. Its primary function is to act as a cleansing agent, helping to remove dirt, oil, and impurities from the skin and hair. SLES is favored in the cosmetic industry due to its excellent foaming properties and cost-effectiveness.
At MAHACO, we understand that consumers are increasingly interested in the science behind cosmetic ingredients. SLES is derived from ethoxylated lauryl alcohol, and its widespread use is attributed to its ability to create a rich, luxurious lather that enhances the user experience.
Can SLES Cause Skin Irritation?
The potential for SLES to cause skin irritation has been a topic of debate among dermatologists and cosmetic chemists. While SLES is generally considered safe for use in rinse-off products at concentrations typically found in cosmetics, some individuals may experience irritation, particularly if they have sensitive skin or pre-existing skin conditions such as eczema.

The irritation potential of SLES is influenced by several factors:
Concentration: Higher concentrations of SLES are more likely to cause irritation.
Frequency of Use: Frequent or prolonged exposure can increase the risk of irritation.
Formulation: The presence of other soothing or moisturizing ingredients can mitigate the irritating effects of SLES.
MAHACO recommends that cosmetic manufacturers adhere to regulatory guidelines regarding SLES concentrations and conduct thorough safety testing to ensure consumer safety.
Industry Trends: The Shift Toward Gentle Cleansers
As the demand for gentle, skin-friendly products grows, the cosmetic industry is exploring alternative surfactants and innovative formulations. Companies like MAHACO are at the forefront of this shift, offering a range of mild surfactants and sulfate-free options to meet diverse consumer needs.
The trend toward “clean beauty” has prompted brands to reformulate products, reducing or eliminating SLES and other potentially irritating ingredients. This movement is driven by both consumer preference and emerging research highlighting the importance of maintaining the skin’s natural barrier function.
Comparing SLES with Sodium Lauryl Sulfate (SLS)
It is important to distinguish between SLES and Sodium Lauryl Sulfate (SLS), another common surfactant. SLES is generally considered less irritating than SLS due to the addition of ethoxyl groups, which make it milder on the skin. However, both ingredients can cause irritation in susceptible individuals.
MAHACO provides both SLES and SLS to manufacturers, ensuring transparency about their properties and appropriate usage. The choice between these two surfactants depends on the application, desired performance, and target consumer demographic.
Regulatory Perspectives and Safety Assessments
Global regulatory agencies, including the European Commission and the U.S. Food and Drug Administration (FDA), have evaluated the safety of SLES in cosmetic products. These agencies have concluded that SLES is safe for use in rinse-off products when used at recommended concentrations.
MAHACO closely monitors regulatory updates and ensures all supplied raw materials comply with international safety standards. Our technical team is available to assist clients with formulation advice and regulatory compliance.
