For purchasing managers and product developers, understanding the critical specifications of chemical ingredients is fundamental to ensuring successful formulations and efficient operations. Sodium Lauryl Ether Sulfate (SLES) 70% is a prime example of such an ingredient, widely used for its excellent surfactant properties. As a seasoned manufacturer and supplier of chemical auxiliaries, we aim to provide clarity on what buyers should prioritize when looking to purchase SLES 70%.

The '70%' in SLES 70% refers to its active matter content, meaning it contains at least 70% of the actual surfactant compound. This is a crucial specification because it directly impacts the efficacy and concentration needed in your formulations. High active matter content ensures that you use less product to achieve the desired cleansing or foaming effect, leading to cost savings and potentially simpler formulation adjustments. When you buy SLES 70%, always confirm this active matter percentage.

Another vital parameter is the appearance. High-quality SLES 70% is typically described as a white to light yellow translucent gel or paste. Any significant deviation from this could indicate impurities or improper manufacturing processes. As a supplier committed to quality, we ensure our SLES 70% meets these visual standards, providing a predictable and reliable raw material.

The pH value of a 2% aqueous solution is also critical. For SLES 70%, this typically falls within the range of 6.5 to 9.5. A stable and appropriate pH is essential for product stability and compatibility, especially in personal care and cosmetic applications where skin sensitivity is a concern. An incorrect pH can affect the efficacy of other ingredients or even lead to undesirable skin reactions.

Furthermore, buyers should pay attention to the unsulfated matter and sodium sulfate content. Low levels of unsulfated matter (typically below 3.5%) and sodium sulfate (often below 1.5%) are indicative of a purer product with fewer by-products. These specifications, along with a low Klett color value (e.g., 30 max for 5% aqueous solution), signify a cleaner, higher-quality SLES 70% that will perform better and avoid unwanted side effects in your final products.

When you decide to buy SLES 70%, especially in bulk, partnering with a reputable manufacturer and supplier like us is paramount. We ensure that our products meet all these critical specifications, offering transparency and reliability. Understanding these technical details empowers you to make informed purchasing decisions and source the best possible raw material for your diverse formulation needs, whether for personal care or industrial applications.
