C12-16 Pareth is a chemical compound frequently found in numerous household products. This ingredient is a synthetic blend of fatty alcohols and polyethylene glycols. It is included in formulations to help different components mix and to enhance product performance.
Understanding C12-16 Pareth
C12-16 Pareth is classified as an ethoxylated fatty alcohol. The “C12-16” in its name specifies that the fatty alcohol component is derived from carbon chain lengths ranging from 12 to 16 carbon atoms. The “Pareth” designation indicates it is a polyethylene glycol (PEG) ether of an alkyl alcohol. The number often following “Pareth,” such as in C12-16 Pareth-9, denotes the average number of repeating ethylene oxide units. This compound is entirely synthetic, not naturally occurring.
The Role of C12-16 Pareth in Products
The primary function of C12-16 Pareth in various products is that of a surfactant and emulsifier. Surfactants work by reducing the surface tension of liquids, which allows them to spread more easily and interact more effectively with other substances. This property is particularly useful for combining ingredients that normally would not mix, such as oil and water, enabling them to form stable, finely dispersed mixtures known as emulsions. This capability stems from the unique molecular structure of C12-16 Pareth, which possesses both an oil-attracting and a water-attracting part. Ultimately, it assists products in cleansing, generating foam, and ensuring that diverse components are well-blended.
Where You Find C12-16 Pareth
C12-16 Pareth is a common ingredient in a wide array of cleaning products and personal care items. Its presence is noted in various formulations such as laundry detergents, dish soaps, and all-purpose household cleaners. Beyond cleaning agents, it is also incorporated into many cosmetic and personal care products. These include shampoos, conditioners, hair treatments, facial moisturizers, and body washes.
Safety Considerations for C12-16 Pareth
Initial Safety & Irritation
When used in typical concentrations within cosmetic formulations, C12-16 Pareth is generally regarded as safe and non-sensitizing for the skin. Regulatory bodies, such as the Cosmetic Ingredient Review (CIR) Expert Panel, have evaluated similar compounds, finding them safe when properly formulated to prevent irritation. Assessments often leverage data from analogous chemicals, considering that larger molecules like C12-16 Pareth are less likely to deeply penetrate the skin. While skin irritation is generally uncommon, concentrated forms or prolonged contact may lead to dry skin or irritation, and eye contact can also result in slight irritation.
1,4-Dioxane & Environmental Impact
Some ethoxylated ingredients, including C12-16 Pareth, may contain trace amounts of 1,4-dioxane as a byproduct of their manufacturing process. This substance is considered a potential carcinogen, though some manufacturers employ methods like vacuum-stripping to reduce its presence. Overall safety assessments for ingredients like C12-16 Pareth consider its concentration and the product’s intended use. Regarding environmental impact, surfactants broadly can affect aquatic organisms if released into waterways.
