The origin, nature and introduction of Ceteareth

Ceteareth is a compound used in the cosmetic and pharmaceutical industries as an emulsifier and surfactant. It belongs to the group of chemical compounds known as ethoxylated alcohols. Ethoxylated alcohols are produced through the ethoxylation process, where ethylene oxide is added to fatty alcohols. This results in the formation of polyethylene glycol ethers of fatty alcohols.

Here’s a breakdown of the origin, nature, and introduction of Ceteareth:


1.Chemical Synthesis: Ceteareth is synthesized through the ethoxylation of cetyl or stearyl alcohol, which are fatty alcohols derived from natural sources like coconut oil or palm oil.

2.Natural Sources: While the base alcohols can be derived from natural sources, the ethoxylation process involves chemical synthesis.

1.Chemical Structure: Ceteareth is a polyethylene glycol ether of cetyl or stearyl alcohol. The number following the “Ceteareth” designation (e.g., Ceteareth-20 or Ceteareth-25) indicates the average number of ethylene oxide units added during the ethoxylation process.

2.Function: Ceteareth acts as an emulsifier and surfactant. In skincare and cosmetic formulations, emulsifiers help blend water and oil-based ingredients, creating stable and uniform products. Surfactants, on the other hand, reduce the surface tension between different substances, allowing them to mix more easily.


1.Cosmetic and Pharmaceutical Industries: Ceteareth is widely used in the formulation of creams, lotions, and other cosmetic or pharmaceutical products where emulsification and stabilization are necessary.

2.Benefits: Its use in skincare products helps improve the texture, stability, and shelf life of formulations. It also contributes to the spreadability and absorption of products on the skin.

3.Regulatory Approval: Ceteareth and related compounds are generally considered safe when used within specified concentrations, and they have received approval from regulatory bodies for use in cosmetics.

It’s essential to note that while Ceteareth is a common ingredient in many cosmetic and pharmaceutical products, individuals with specific skin sensitivities may want to check product labels or consult with dermatologists to ensure the suitability of products containing this ingredient for their skin. Additionally, the sourcing of the base alcohols (cetyl or stearyl alcohol) can impact the overall sustainability and ethical considerations associated with products containing Ceteareth.
