Sodium Cocoyl Isethionate (SCI) is a highly valued ingredient in the personal care industry due to its exceptional mildness, luxurious lather, and moisturizing properties. However, like many specialty surfactants, it requires specific handling and formulation techniques to achieve optimal performance. At NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of high-quality cosmetic raw materials, we aim to equip formulators with the knowledge needed to successfully incorporate SCI into their products. This guide provides practical tips for formulators looking to buy and effectively utilize SCI.

Understanding SCI's Properties for Formulation Success

SCI is typically supplied as a powder, flakes, or noodles. Its unique chemical structure, while beneficial for its performance, can present challenges in terms of solubility, particularly in water-based systems. Unlike some other surfactants, SCI is only slightly miscible in water and may require assistance for full dispersion and incorporation.

Key Formulation Tips:

  • Melting and Dispersion: For liquid formulations, it is often recommended to gently melt or hydrate SCI before mixing it with other ingredients. Applying slow, steady heat can help increase its melting rate. Avoid overheating.
  • Use of Co-Surfactants: To improve SCI's solubility and create stable liquid systems, it's highly effective to use it in conjunction with other surfactants. Surfactants like cocamidopropyl betaine or other milder anionic/non-ionic surfactants can act as solubilizers or co-emulsifiers, helping to keep SCI dispersed and preventing recrystallization. This synergy allows for clearer formulations and higher incorporation levels.
  • Solid Formulations (Shampoo Bars, Cleansing Bars): SCI is exceptionally well-suited for solid formulations. In these applications, it often requires less complex processing. The material can sometimes be incorporated without melting, or with minimal heat, often requiring pressing or extrusion to form the final product. Its solid form contributes to the hardness and longevity of the bars.
  • pH Considerations: SCI generally has a slightly acidic to neutral pH in aqueous solutions. While it can sometimes help achieve a skin-friendly pH, it's always advisable to test and adjust the final product's pH as needed, perhaps with a mild alkali like sodium bicarbonate if aiming for a more neutral range.
  • Incorporation Order: In liquid systems, it is often beneficial to add SCI to the surfactant phase, allowing it to hydrate or melt before combining with the bulk of the formulation. Using a high-shear mixer can aid in achieving a uniform dispersion.
