Laureth - 4, with the CAS number 68439 - 50 - 9, is a high - quality product available at the best price. Chemically, it is an ethoxylated alcohol, specifically a polyethylene glycol ether of lauryl alcohol. It usually appears as a clear to slightly yellowish liquid or paste.
The chemical formula of Laureth - 4 can be generally represented as C₁₂H₂₅(OCH₂CH₂)₄OH. It has a relatively low molecular weight compared to some of its higher - ethoxylated counterparts. The product typically has a pH value in a slightly acidic to neutral range, which makes it suitable for use in a variety of formulations. It has good solubility in both water and most common organic solvents, which is an important property for its application in different industries.
Laureth - 4 has a wide range of uses across multiple industries. In the personal care industry, it is commonly used as an emulsifier and surfactant. As an emulsifier, it helps to mix oil and water phases in creams, lotions, and hair care products. This ensures a stable and homogeneous product, preventing the separation of oil and water components over time. As a surfactant, it reduces the surface tension of liquids, allowing for better spreading and wetting of the product on the skin or hair. This enhances the cleansing ability of shampoos, body washes, and facial cleansers.
In the industrial cleaning sector, Laureth - 4 is used in formulations of heavy - duty cleaners. Its surfactant properties enable it to break down and remove grease, oil, and dirt from various surfaces. It can be found in degreasers for machinery, floor cleaners, and automotive cleaning products.
It also has applications in the textile industry. It can be used as a wetting agent during the dyeing process, ensuring uniform color distribution on the fabric. Additionally, it helps in reducing the surface tension of the dye bath, allowing the dye to penetrate the fibers more effectively.
When using Laureth - 4 in personal care formulations, it should be added at an appropriate stage of the production process. Usually, it is added during the emulsification step. The recommended concentration in creams and lotions is typically between 1% - 5%. For hair care products, the concentration can be adjusted according to the specific formulation requirements, but generally ranges from 0.5% - 3%.
In industrial cleaning products, the usage amount depends on the type and severity of the dirt to be removed. For light - duty cleaners, a concentration of around 2% - 5% may be sufficient. For heavy - duty degreasers, the concentration can be increased up to 10% or even higher.
When using it in the textile industry, it is often added to the dye bath at a concentration of 0.1% - 1%. The fabric should be thoroughly immersed in the bath with proper agitation to ensure even wetting and dye penetration.
Case 1: Personal Care - Moisturizing Lotion
A cosmetic company was developing a new moisturizing lotion. They added 3% Laureth - 4 during the emulsification process. The resulting lotion had a smooth texture and did not separate even after several months of storage. Consumers reported that the lotion spread easily on the skin and provided long - lasting moisture, thanks to the emulsifying and wetting properties of Laureth - 4.
Case 2: Industrial Cleaning - Machinery Degreaser
A manufacturing plant was facing problems with removing stubborn grease from its machinery. They formulated a degreaser with 8% Laureth - 4. After applying the degreaser, the grease was effectively removed, and the machinery was restored to its normal working condition. The degreaser was also environmentally friendly compared to some traditional solvents, due to the relatively low toxicity of Laureth - 4.
Case 3: Textile Industry - Cotton Dyeing
A textile mill was dyeing cotton fabric. They added 0.5% Laureth - 4 to the dye bath. The result was a more uniform color on the fabric, with no streaks or uneven patches. The dye penetration was improved, leading to a more vibrant and long - lasting color on the cotton.
