Product Introduction

Ceteth-60 is a nonionic surfactant and emulsifier manufactured through the ethoxylation of cetyl alcohol. It is characterized by a polyethylene glycol chain containing an average of 60 ethylene oxide units. This high degree of ethoxylation makes it water-soluble and contributes to its functionality in cosmetic formulations. Ceteth-60 functions primarily to help mix oil and water, stabilizing emulsions, and supporting the dispersion of ingredients, thereby enhancing product texture and application. It is commonly utilized in a variety of personal care and cosmetic products due to its versatility and mildness.

Production Process

The production of ceteth-60 involves the ethoxylation of cetyl alcohol, a fatty alcohol derived from vegetable or synthetic sources. The process begins with reacting cetyl alcohol with ethylene oxide in the presence of a catalyst, typically an alkaline catalyst such as sodium hydroxide or potassium hydroxide [1]. The reaction is carefully controlled by monitoring temperature, pressure, and the ratio of reactants to achieve the desired degree of ethoxylation, specifically 60 ethylene oxide units. After the ethoxylation process is complete, the reaction mixture is neutralized, and purified to remove any residual reactants or by-products, ensuring the final product meets the required purity standards for cosmetic use [2].

Efficacy and Function

Ceteth-60 primarily functions as an emulsifier, helping to stabilize mixtures of oil and water by reducing the interfacial tension between the two phases [3]. Its hydrophilic-lipophilic balance (HLB) value contributes to its effectiveness in creating stable emulsions. It also acts as a surfactant, aiding in the dispersion of ingredients and enhancing the overall texture and feel of cosmetic products. Additionally, ceteth-60 can act as a solubilizer for certain oil-soluble ingredients, improving their incorporation into water-based formulations. Its mildness and low irritation potential make it suitable for use in a wide range of personal care products.

Application Scenarios

Ceteth-60 is utilized across diverse cosmetic and personal care applications including creams, lotions, cleansers, and hair care products [4]. In creams and lotions, it aids in creating stable emulsions, providing a smooth and consistent texture. In cleansers, it functions as a surfactant, assisting in removing dirt and oil from the skin. In hair care products like conditioners and shampoos, ceteth-60 helps to improve the product's consistency and facilitates even distribution. Its versatility makes it a valuable ingredient, for enhancing product performance and consumer experience.

Packaging and Transportation

Ceteth-60 is generally packaged in polyethylene (PE) bags or fiber drums with PE liners to prevent contamination and maintain product integrity during storage and transportation. The packaging material is chosen to protect the product from moisture, air, and light, which can affect its quality. Transportation should adhere to standard practices for non-hazardous materials, ensuring the product is kept in a cool, dry environment. Proper labeling, including the product name, batch number, and expiration date, is essential. Safety precautions during handling should minimize dust formation and prevent contact with skin and eyes.
