Chemical Description

  • Ethoxylated Hydrogenated Castor Oil (EHO), also known as PEG-40 Hydrogenated Castor Oil, is a non-ionic surfactant obtained by the ethoxylation of hydrogenated castor oil. This process involves reacting hydrogenated castor oil with ethylene oxide to produce a product that is more water-soluble than the original oil, while retaining the unique properties of castor oil.
  • It is characterized by its clear to pale yellow viscous liquid appearance and is known for its excellent emulsifying, solubilizing, and dispersing properties. Due to its versatility, it finds applications across a wide range of industries.
  • In the cosmetic and personal care industry, EHO is widely used as a surfactant, emulsifier, and solubilizer in formulations such as creams, lotions, shampoos, and bath oils. Its compatibility with skin and hair, along with its ability to blend oil and water-soluble ingredients effectively, makes it an essential ingredient in many products.
  • The pharmaceutical industry utilizes EHO as an emulsifier and solubilizer in drug formulations, enhancing the bioavailability of medications and facilitating the creation of stable emulsions.
  • As a non-ionic surfactant, it is used in the manufacturing of detergents, cleaners, and other surfactant-based products where gentle, yet effective cleaning is required. Its ability to reduce surface tension makes it ideal for applications that require the removal of oils and greases.
  • In industrial applications, EHO serves as a lubricant and release agent due to its excellent lubricating properties and compatibility with various materials. It is also employed in the production of textiles, inks, and coatings where its emulsifying and stabilizing actions are beneficial.
  • In the polymer and plastics industry, Ethoxylated Hydrogenated Castor Oil acts as a plasticizer and dispersing agent, aiding in the processing of polymers and enhancing the properties of final products.
  • EHO is explored for its role in environmental technologies, particularly in water treatment and soil remediation, due to its ability to emulsify and solubilize hydrophobic contaminants.
  • Its biodegradability and low toxicity profile make it a preferred choice for applications requiring environmentally friendly solutions.
