Sodium Cocoyl Isethionate (SCI) powder is a highly sought-after ingredient for formulators looking to create mild, effective, and aesthetically pleasing personal care products. Its powdery form offers distinct advantages in handling and incorporation, especially for anhydrous (water-free) formulations like solid shampoo bars. NINGBO INNO PHARMCHEM CO.,LTD. supplies premium SCI powder, along with the expertise to guide your formulation process.

Why SCI Powder?

SCI is available in various forms, including flakes, noodles, and powder. The powder form is often preferred for its ease of dispersion and incorporation into solid formulations. It allows for a more uniform distribution of the surfactant throughout the product, leading to consistent performance and a smoother final product texture.

Key Considerations for Formulating with SCI Powder:

  • Anhydrous Formulations (e.g., Shampoo Bars): For solid shampoo bars, SCI powder is often used alongside other solid ingredients like butters (e.g., cocoa butter, shea butter), clays, and essential oils. The process typically involves gently melting the butters and then combining them with the dry ingredients, including SCI powder. The mixture is then pressed or molded into bars. Due to its powdery nature, SCI can be easily blended in without significant clumping.
  • Liquid Formulations: While SCI powder is less soluble in water than some liquid surfactants, it can be incorporated into liquid products. However, it often requires gentle heating (around 50-60°C) and stirring to fully dissolve and create a stable emulsion. Using co-surfactants or solubilizers can also aid in its dispersion.
  • Usage Rates: The recommended usage rate for SCI typically ranges from 3% to 20% for rinse-off products, depending on the desired foaming and cleansing intensity. For solid shampoo bars, higher concentrations (20-60%) are common to ensure adequate lather and cleansing power.
  • Handling Precautions: While SCI is generally mild, it is still a powder and can cause airborne dust. Always use in a well-ventilated area and consider wearing a dust mask and gloves to prevent inhalation or skin irritation during handling.
  • pH: SCI generally works well within a pH range that is friendly to skin and hair (around 5.0-6.5). This means minimal pH adjustment is often needed when formulating with SCI.

Tips for Success:

  • Pre-blending: For dry mixes, pre-blending SCI powder with other dry ingredients can ensure a more homogeneous mixture.
  • Gentle Heating: If heating is required for liquid formulations, avoid excessive temperatures, as this can degrade the surfactant.
  • Mixing Techniques: For liquid products, using a high-shear mixer can help break down SCI particles and create a stable emulsion.
  • Sourcing Quality: Always source SCI powder from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. to ensure purity, consistent particle size, and reliable performance.
