Question

I would like advice on formulating a bar soap similar to Cetaphil. I want to know how to make a chemical soap into a solid bar format. The formula is as follows:

Ingredients Cetaphil bar soap:
Sodium Cocoyl Isethionate, Stearic Acid, Sodium Tallowate, Water, Sodium Stearate, Sodium Dodecylbenzene Sulfonate, Sodium Cocoate, PEG-20, Sodium Chloride, Masking Fragrance, Sodium Isethionate, Petrolatum, Sodium Isostearoyl Lactylate, Sucrose Cocoate, Titanium Dioxide, Pentasodium Pentetate, Tetrasodium Etidronate. May Also Contain Sodium Palm Kernelate

Thank you.

How to Make a Solid Syndet Bar (like Cetaphil)

Thank you for providing the ingredient list for the Cetaphil bar soap. These ingredients are typical components used in the production of Syndet Bars, which are soap bars primarily made from synthetic detergents rather than the reaction of oils and lye used in traditional soaps.

Producing a Syndet Bar is different from making Cold Process or Melt and Pour soaps commonly made at home. The manufacturing process for Syndet Bars typically requires specialized industrial equipment and techniques, such as:

  • Mixing and Drying: Ingredients are mixed together and often undergo a drying process to reduce water content.
  • Shaping: The mixture is then formed into bars, potentially through milling and extruding.
  • Hardening and Cutting: The bars are hardened and cut to the desired size.

Key ingredients you see in the list, such as Sodium Cocoyl Isethionate and Stearic Acid, are important components in Syndet Bars:

  • Sodium Cocoyl Isethionate (e.g., BabyFoam™): This is a gentle surfactant commonly used in cleansing products for sensitive skin. It provides good lathering and cleansing properties and is suitable for solid (Syndet Bar) formulations.
  • Stearic Acid: This is a fatty acid that helps give the bar its solid structure and can improve the texture of the soap.

Due to the complexity of the manufacturing process and the need for specific equipment, it is difficult to create this type of bar soap using traditional home soap-making methods.

If you are interested in other ingredients on the list, feel free to ask! I can provide basic information about their properties.
