NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing clear and accurate information about the chemical ingredients we supply. Among the most frequently discussed surfactants are Sodium Lauryl Sulfate (SLS) and Sodium Lauryl Ether Sulfate (SLES), particularly when it comes to their suitability for sensitive skin. While both are effective cleansing agents, SLES 70% offers distinct advantages, especially for formulations targeting individuals with sensitive skin or scalps. This blog post aims to clarify these crucial differences.

The fundamental difference between SLS and SLES lies in their manufacturing process and, consequently, their properties. SLS, while a powerful surfactant, is known for its strong degreasing action and potential to strip natural oils from the skin and hair. This can lead to dryness, irritation, and for some individuals, exacerbate conditions like eczema or psoriasis. In contrast, SLES is produced by ethoxylating SLS. This process introduces ethylene oxide groups, which significantly modifies the molecule, making it considerably milder and less irritating than SLS. This makes understanding the difference between SLS and SLES vital for product developers.

The lower irritation potential of SLES 70% makes it an excellent choice for a wide array of personal care products. In shampoos and conditioners, it provides effective cleansing without stripping the scalp of its natural protective barrier, which is essential for maintaining scalp health. For body washes and facial cleansers, SLES 70% ensures a gentle yet thorough clean, leaving the skin feeling refreshed rather than dry or tight. This milder profile also extends to eye irritation, where SLES is generally considered less problematic than SLS.

When formulators are developing products for specific consumer needs, understanding the nuances of surfactants is key. For example, brands looking to create baby care products, hypoallergenic cleansers, or products aimed at individuals with sensitive or compromised skin will find SLES 70% to be a superior choice over SLS. The ability to buy SLES 70% knowing its gentler nature provides formulators with the confidence to create products that are both effective and well-tolerated by a broader consumer base. This focus on mildness does not compromise the essential cleansing and foaming capabilities.

It is also important to address some common misconceptions. While some online discussions might erroneously link SLES with harmful side effects, extensive scientific research and regulatory reviews have consistently affirmed its safety for use in cosmetic and personal care products when manufactured and formulated correctly. The key is the ethoxylation process, which transforms SLS into the milder SLES. By choosing a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD., you ensure access to high-quality SLES 70% that meets rigorous safety and performance standards.

In conclusion, for formulators seeking effective cleansing agents, particularly for products designed for sensitive skin, SLES 70% is the preferred option over SLS. Its gentler nature, derived from the ethoxylation process, provides a balance of cleaning power and mildness that is crucial for a positive user experience. We at NINGBO INNO PHARMCHEM CO.,LTD. are proud to offer SLES 70% as a key ingredient to help you create successful and consumer-preferred products.
