Sodium Cocoyl Isethionate (SCI) is a versatile and highly valued surfactant in the cosmetic industry, celebrated for its mildness and excellent foaming properties. However, like any specialized ingredient, understanding how to best incorporate it into formulations is key to unlocking its full potential. NINGBO INNO PHARMCHEM CO., LTD. offers high-quality SCI and supports formulators with valuable insights.

When working with SCI, formulators often encounter different physical forms, such as powder, granules, or noodles. For solid products like shampoo bars, the physical form can influence ease of incorporation. Fine powders and granules are generally easier to melt and blend, ensuring a homogeneous mixture. For liquid formulations, however, dissolving SCI can be more challenging as it is not readily soluble in water. A common and effective technique is to create a slurry with a liquid amphoteric surfactant, such as Cocamidopropyl Betaine, and gently heat the mixture until a uniform paste is formed.

This paste can then be smoothly integrated into the water phase of a liquid formulation. Using a high-shear mixer can further enhance the process, achieving a silky smooth texture without causing excessive foaming. For larger batches, pre-preparing this SCI-surfactant paste and storing it can save significant time during production. It's also important to note that SCI can hydrolyze in hydrous formulations with a pH below 6, potentially leading to instability. Therefore, maintaining a pH between 6 and 8 in liquid products containing SCI is generally recommended for optimal stability.

For those new to using SCI, starting with recommended usage rates is advisable. Typically, liquid formulations might use 5-15% SCI, while solid bars can incorporate much higher percentages, often starting around 30% and going up to 50% or more, depending on the desired lather and cleansing efficacy. Experimentation with different SCI forms and concentrations, combined with understanding its solubility and stability characteristics, will enable formulators to create outstanding products. NINGBO INNO PHARMCHEM CO., LTD. is a reliable source for SCI, ensuring consistency and quality for your formulation needs.
