The world of surfactants can be confusing, with terms like SLS and SLES often used interchangeably, yet representing distinct chemical entities. For formulators and procurement managers, understanding the difference between Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) is vital for selecting the right ingredient for their products. SLES 70% has emerged as a popular alternative due to its milder nature, making it a go-to choice for many applications. If you are considering purchasing these surfactants, this comparison will be invaluable.

Sodium Lauryl Sulfate (SLS) is a potent anionic surfactant known for its excellent foaming and cleaning capabilities. However, it can also be quite harsh and irritating, often stripping the skin and hair of their natural oils, leading to dryness and potential sensitivity. This harshness is why many consumers and formulators seek gentler alternatives. When you aim to buy SLES, you are often seeking a product that retains the effective cleaning power but with a significantly improved skin compatibility profile.

Sodium Laureth Sulfate (SLES) is essentially a modified version of SLS, created through a process called ethoxylation. This chemical modification adds ethylene oxide chains, which increases the molecule's water solubility and reduces its irritating potential. As a result, SLES 70% is much milder on the skin and eyes, making it ideal for a wide range of personal care products, including shampoos, body washes, and facial cleansers. Its ability to produce a rich, stable lather further enhances its appeal.

When choosing between SLS and SLES, formulators must consider the end-user's skin sensitivity and the product's intended application. For products requiring a gentle yet effective cleanse, SLES 70% is the clear winner. If you are looking to purchase this milder surfactant, partnering with a reputable manufacturer in China can provide access to high-quality SLES 70% at competitive prices. Ensuring you buy from a trusted supplier guarantees you receive a product that performs as expected and meets your quality standards.
