What is C9-C11 alcohol ethoxylate
C9-C11 alcohol ethoxylate, also called C9-11 Pareth, is a colorless liquid derived from palm kernel or coconut oil.[1,2]
What C9-C11 alcohol ethoxylate does in our products
C9-C11 alcohol ethoxylate is an emulsifier and a surfactant that breaks the surface tension of water, allowing things to become clean. It can be found in detergents and personal care products, such as styling mousse, hair gel, and other styling products.[3,4]
How C9-C11 alcohol ethoxylate made
Commercial alcohol ethoxylate is a mixture of several homologues of varying carbon chain length and degree of ethoxylation. Homologues that are not ethoxylated are also called aliphatic alcohols or simply fatty alcohols. Primary alcohol ethoxylates are made via ethoxylation of primary alcohols with ethylene oxide, using base catalyzed reaction with potassium or sodium hydroxide. Neutralization with an acid such as acetic or phosphoric acid then occurs. Most commercial alcohol ethoxylates are made and delivered as solids, pastes, or solutions.
Why we use C9-C11 alcohol ethoxylate
We use C9-C11 alcohol ethoxylate as an alternative to ammonia. It has the unique ability to clean a surface and then evaporate without leaving a residue (which is especially helpful when cleaning glass, stainless steel and similar surfaces). Although ethoxylated alcohols may experience 1,4 dioxane contamination as a byproduct of the production process, the EPA considers it safe to consume water with 4 ppm of 1,4 dioxane for one day or 0.4 ppm of 1,4 dioxane for 10 days. A study of workers exposed to 0.006–14.3 ppm 1,4-dioxane for an average of 25 years found no evidence of liver or kidney disease or any other clinical effects, and another study found no differences between observed and expected incidences of cancer among workers at a manufacturing and processing facility. Puracy has signed certifications from our ingredient providers that show no more than 2 ppm of 1,4 dioxane in our most concentrated finished product. We only use these ingredients in cleaners, which are rinsed or wiped away with a cloth rather than applied to the skin.
