Ceteareth-25 is a versatile nonionic emulsifier known for its ability to effectively form oil-in-water emulsions, utilizing its 25-mole ethoxylate composition derived from a blend of cetyl and stearyl alcohols. It presents as a free-flowing microbead and possesses an HLB value of 15-17. When dissolved in water or alcohol, Ceteareth-25 produces a colloid or a clear solution, and it is compatible with various substances such as vegetable and mineral fats and oils, fatty alcohols, fatty acids, mono- and di-stearates, and polyethylene glycols. This emulsifier is particularly advantageous in creating emulsion preparations with a diverse range of polarities, especially when combined with Ceteareth-6 and Stearyl Alcohol to develop creams or lotions. Moreover, Ceteareth-25 enhances the stability of colloids and dispersed systems. At higher concentrations, between 21% and 30%, it functions as a gel-forming agent, enabling the production of gel-like brushable products. Typically, its usage concentration ranges from 1% to 5%.
What is Ceteareth-25 and what is its primary function in formulations?
Ceteareth-25 is a nonionic emulsifier, specifically the 25-mole ethoxylate of a blend of cetyl and stearyl alcohols. It is primarily used to create stable oil-in-water emulsions by helping to mix oil and water-based components in cosmetic and personal care formulations.
Can Ceteareth-25 dissolve in water and other substances?
Yes, Ceteareth-25 can dissolve in water and alcohol to form a colloid or a clear solution. It is also soluble in vegetable and mineral fats and oils, as well as with fatty alcohols, fatty acids, mono- and di-stearates, and polyethylene glycols.
What are the typical usage levels for Ceteareth-25 in product formulations?
Ceteareth-25 is typically used at concentrations of 1-5% in formulations. It can be used in higher concentrations, up to 21-30%, when acting as a gel-forming agent for gel-like products.
How does Ceteareth-25 contribute to the stability of colloids and dispersed systems?
Ceteareth-25 enhances the stability of colloid and dispersed systems, making it an excellent choice for formulations where maintaining the uniform dispersion of ingredients is essential.
What are the preferred combinations for using Ceteareth-25 in creams or lotions?
For creating creams or lotions, Ceteareth-25 is preferably used in combination with Ceteareth-6 and Stearyl Alcohol. This combination helps to achieve an optimal balance of emulsion stability and emollient properties, thereby improving the feel and performance of the product.
Can Ceteareth-25 be used to create gel-like products?
Yes, in higher concentrations ranging from 21% to 30%, Ceteareth-25 can function as a gel-forming agent, allowing the creation of gel-like brushable products with ease.
What are the benefits of using Ceteareth-25 in cosmetic formulations?
Ceteareth-25 offers several benefits in cosmetic formulations, including its ability to create stable emulsions, compatibility with a wide range of polarities, and enhancement of colloid stability. Its versatility allows it to be used across various product types, from creams and lotions to gel-based applications.
