Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) are commonly used ingredients classified as surfactants. Their main functions are:
Removing dirt and oil from the skin or hair surface
Providing the desired foaming properties in a formulation
For these reasons, they are widely used in cleansing product categories such as shampoos, shower gels, facial cleansers, liquid soaps, and hand washes.
When Is the “SLS/SLES-Free” Claim Meaningful?
If a product has cleansing properties and is intended to be rinsed off after use, such a claim is relevant from a formulation perspective. For example:
The “SLS/SLES-free” claim is valid and informative for a shampoo formulated with alternative, milder surfactants.
In cleansing products specially developed for sensitive or atopic skin, this claim reflects both the product's positioning and its target audience.
Is It Necessary for Every Product Category?
No. If the product is a leave-on formulation such as a moisturizing cream, body lotion, or eye contour serum, which does not have cleansing properties, using the “SLS/SLES-free” claim may be scientifically and commercially misleading. These types of products do not typically include such surfactants in their formulation and do not serve cleansing functions. In this case, a label stating “SLS-free” may create unnecessary concern or mislead the consumer about the product's technical content.
Scientific Consistency and Consumer Trust in Label Claims
Brands that prioritize consumer health must ensure that the claims used on product labels are:
Directly related to the product’s formulation
Appropriate for the target user group
⇒ Under the EU Cosmetics Regulation (EC No 1223/2009), there are specific provisions against misleading labeling.
In compliance with scientific and legal regulations
Why Is This Important for Consumers?
“Free from” claims are especially critical for consumers with sensitive skin or dermatological concerns when choosing products. However, using these claims only when valid and necessary is an ethical responsibility that supports both brand credibility and consumer education.
To build trust with your brand’s target audience and ensure regulatory compliance, you should make “free from” claims only for the appropriate product categories and with valid scientific justification. This approach not only improves consumer satisfaction but also enhances long-term brand value.
