Understanding PEG-40 Hydrogenated Castor Oil

PEG-40 Hydrogenated Castor Oil is a modified (polyethoxylated form) of hydrogenated castor oil. Castor oil is very simple to treat with hydrogen in order to make it more solid and stable, and then it is mixed with ethylene oxide, making it a water-soluble, non-ionic surfactant.

This procedure makes it distinctive in the following aspects:

  • Great Solubilizer: Designed to combine essential oils, scents, and other oil-soluble products into water-based products.
  • Consistent Emulsifier: Forms smooth and even textures in creams, lotions, and gels.
  • Skin-Friendly: It is commonly used in skincare and is not very irritating or harsh.

PEG-40 Hydrogenated Castor Oil, in addition to these characteristics, adds to the clarity and shelf life of cosmetic products and provides a rich, soft feel on the skin. In addition to personal care, it is also appreciated in the pharmaceutical and industrial fields due to its flexibility and safety profile. It is a good solubilizer and emulsifier, and thus it is a good ingredient to use in formulation, as it gives consistency, performance, and consumer-friendly outcomes.
