1,3-Butanediol plays a crucial role in cosmetics and personal care products. It is mainly used as a moisturizer, which can effectively absorb and lock in moisture, helping the skin stay moist and soft. In addition, butanediol also has good solubility, which can dissolve various active ingredients such as vitamins, antioxidants, etc., thereby enhancing the efficacy of the product. In skin care products, butanediol is often used to make face cream, lotion, essence and other products to provide lasting moisturizing effect for the skin. In cosmetics, such as lipstick and eye shadow, butanediol is used as solvent and thickener to help adjust the texture and stability of products.
In the field of medicine, butanediol also has a wide range of applications. It is often used as a solvent and carrier for drugs, helping them to be better absorbed and utilized by the human body. Meanwhile, butanediol also has certain antibacterial and preservative effects, which can extend the shelf life of drugs. In local medication, such as ointment and gel, butanediol can be used as a matrix to help the drug penetrate the skin better and play a therapeutic role. In addition, butanediol can also be used to prepare some special pharmaceutical preparations, such as injections, oral liquids, etc., providing strong support for the development of the pharmaceutical industry.

Sodium Laureth Sulfate 1EO refers to sodium lauryl ether sulfate, a common anionic surfactant, where 1EO indicates that the lauryl hydrophobic chain in its molecule is connected to one ethoxy (-CH₂CH₂O-) unit. Basic Structure and Properties Chemical Structure: Its general structural formula is:CH3(CH2)10CH2(OCH2CH2)1OSO3Na. It consists of three parts: Hydrophobic group: Lauryl group (C12 alkyl chain) Connecting group: 1 ethoxy unit Hydrophilic group: Sodium sulfate ester group Core Performance Excellent surface activity: It can significantly reduce the surface tension of water, and has strong emulsifying, detergency, and foaming abilities, producing rich and stable foam. Improved water solubility: Compared to sodium lauryl sulfate (SLS) without ethoxy groups, the introduction of one ethoxy unit improves its water solubility, making it less likely to precipitate at low temperatures. Optimized mildness: It is slightly less irritating than SLS, but still belongs to the category of moderately irritating surfactants, suitable for cleaning products. Hard water resistance: It has stronger hard water resistance than SLS, maintaining good cleaning performance in water containing calcium and magnesium ions. Compatibility: It can be compounded with nonionic, cationic (caution is needed to avoid precipitation), and other anionic surfactants. Main Application Areas Personal care products: Used in shampoos, shower gels, facial cleansers, hand soaps, etc., playing a core role in cleaning and foaming. Due to the low number of EO units, it has strong detergency and is often compounded with mild surfactants (such as cocamidopropyl betaine) to reduce irritation. Household cleaning products: Used in laundry detergents, dishwashing detergents, hard surface cleaners, etc., utilizing its emulsifying and foaming abilities to improve cleaning efficiency. Industrial field: It can be used as an emulsifier in pesticide and paint formulations, and also as a wetting agent in the textile industry and a degreasing agent in the leather industry. Differences from similar products Product Eo Number Water-Soluble Mildness Detergency SLS 0 General Lower Strong SLES-1EO 1 Better Moderate Stronger SLES-2EO/3EO 2-3 Very Good Higher Moderate Precautions: At high concentrations, it can be irritating to the skin and eyes. The proportion added to formulations needs to be controlled (usually 5%-15% in personal care products). Avoid high temperatures and strong acidic environments during storage, otherwise hydrolysis may occur, reducing its activity.
