Utilisation et sources d'émission: Agent dispersant LAURETH-23 is classified as : Cleansing; Emulsifying; Surfactant; CAS Number 9002-92-0, COSING REF No: 76947. Chem/IUPAC Name: Poly(oxy-1,2-ethanediyl), .alpha.-dodecyl-.omega.-hydroxy-. Laureth-4 and Laureth-23 are polyoxyethers of lauryl alcohol. They are a clear, colorless liquids. In cosmetics and personal care products, Laureth-4 and Laureth-23 are used in the formulation of a variety of bath, eye, facial, hair, cleansing and sunscreen products. They are also used in cuticle softeners, deodorants and moisturizing products. Laureth-23 is a high HLB emulsifier used in oil-in-water emulsions. Laureth-23 finds use in cosmetic and pharmaceutical products as a surfactant, emulsifier and solubilizer. It is particularly useful in some formulations in light of its chemical inertness to hydrolytic decomposition. Laureth-23 is a nonionic surfactant prepared from lauryl alcohol and 23 moles of ethylene oxide. Laureth-23 contains an average of 23 repeating ethylene oxide units. Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in Laureth-23. The potential presence of this material is well known and can be controlled through purification steps to remove it. Our product has been purified and contains no 1,4-dioxane (0 ppm). The Cosmetic Ingredient Review has reviewed this ingredient and it is declared safe as used up to 6%. INCI: Laureth-23. Description: Solid emulsifier for cosmetic formulations, (white solid, melting point 104°F/40°C, water soluble).

Laureth-23 is a synthetic polymer that is used in many different cosmetics and personal care products as a surfactant and emulsifier. Origin Laureth ingredients are synthesized through a process known as ethoxylation, a chemical reaction in which ethylene oxide is added to a substrate. In this case, the substrate is lauryl alcohol. Lauryl alcohol is obtained from lauric acid, a saturated fatty acid with a 12-carbon atom chain that can be found in palm kernel oil or coconut oil. The number associated with the laureth (i.e. laureth-23) indicates the average number of repeating ethylene oxide units in the molecule. As the numerical value of laureth ingredients increases, the viscosity increases until they become white, waxy solids. Functions In cosmetics and personal care products, laureth-23 functions as a surfactant and emulsifier. It can be found in bath, cleansing, hair, and sunscreen products. It is also used in cuticle softeners, deodorants, and moisturizing products. As a surfactant, laureth-23 works by lowering the surface tension between two substances, such as two liquids or a liquid and a solid. A surfactant molecule contains one end that is hydrophilic (attracted to water) and one end that is lipophilic (attracted to oil). This allows surfactants to attract and suspends oils, dirt, and other impurities that have accumulated on the skin and wash them away. Due to these properties, laureth-23 can be found in many different cleansers and body washes. Laureth-23 is also an emulsifier with an HLB value of 16.9. The acronym HLB stands for Hydrophile-Lipophile Balance, which is an empirical expression for the relationship of the hydrophilic and lipophilic groups of an emulsifier. An HLB greater than 10 means that the substance is soluble in water. High HLB emulsifiers such as laureth-23 give rise to oil-in-water emulsions. Emulsifiers are necessary when a formulation contains both water and oil components. Mixing water and oil together creates a dispersion of oil droplets in water (and vice versa). However, these two phases can separate if the product is left to settle. To address this problem, an emulsifier like laureth-23 can be added to the system to help the droplets remain dispersed. Emulsifiers improve the consistency of a product, which enables an even distribution of topical skin care benefits.
