Its ability to reduce irritation while enhancing foam performance makes it an ideal ingredient for facial cleansers and other personal care products. This surfactant exhibits strong synergy when combined with other surfactants, improving overall cleansing effectiveness without compromising skin compatibility.<\/p>\n<p>INCI Sodium Lauroyl Sarcosinate<\/p>\n<p>CAS 137-16-6<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-medium wp-image-1930\" src=\"https:\/\/www.satcotek.com\/wp-content\/uploads\/2018\/11\/Sarcosinlau-PW-300x214.jpg\" sizes=\"(max-width: 300px) 100vw, 300px\" srcset=\"https:\/\/www.satcotek.com\/wp-content\/uploads\/2018\/11\/Sarcosinlau-PW-300x214.jpg 300w, https:\/\/www.satcotek.com\/wp-content\/uploads\/2018\/11\/Sarcosinlau-PW-260x185.jpg 260w, https:\/\/www.satcotek.com\/wp-content\/uploads\/2018\/11\/Sarcosinlau-PW.jpg 329w\" alt=\"\" width=\"300\" height=\"214\" \/><\/p>\n<h3><strong>Unique Amphiphilic Properties<\/strong><\/h3>\n<p>Sarcosinlau PW features a <strong>hydrophobic 12-carbon lauroyl chain<\/strong> and a <strong>hydrophilic carboxylate group<\/strong>, granting it amphiphilic characteristics. The nitrogen atom within its amide linkage remains <strong>neutrally charged across all pH levels<\/strong>, while the carboxylate group, with a <strong>pKa of approximately 3.6<\/strong>, becomes negatively charged in pH environments above 5.5. These properties contribute to its <strong>stability and performance in various formulations<\/strong>, particularly in pH ranges from 5.5 to alkaline conditions.<\/p>\n<h3><strong>Compatibility and Performance in Formulations<\/strong><\/h3>\n<p>This surfactant demonstrates <strong>excellent compatibility with anionic surfactants<\/strong>, maintaining high foamability even in <strong>salty and hard water conditions<\/strong>. It is stable in soap-based products and light acidic facial cleansers, making it highly versatile for different cleansing applications. Additionally, <strong>Sarcosinlau PW enables the formation of pH-sensitive vesicles<\/strong> when combined with cationic or water-insoluble amphiphiles, further broadening its range of uses in cosmetic formulations.<\/p>\n<p>INCI Sodium Lauroyl Sarcosinate<\/p>\n<h3><strong>Enhancing Delivery of Active Ingredients<\/strong><\/h3>\n<p>A unique characteristic of Sarcosinlau PW is its ability to <strong>form micelle-like aggregates<\/strong> when mixed with non-ionic surfactants such as <strong>sorbitan monolaurate (S20)<\/strong>. This property allows it to act as a carrier for small molecules, including <strong>active ingredients and drugs, aiding in their penetration through the skin<\/strong>. These advanced formulation possibilities make Sarcosinlau PW an innovative choice for modern skincare and personal care products.<\/p>\n<p>INCI Sodium Lauroyl Sarcosinate<\/p>\n<p>CAS
