- Chemical Composition: SLES 28 is a sodium salt of lauryl ether sulfate. It is a mixture of various ethoxylated fatty alcohols containing 28% active SLES and 72% water.
- Surfactant Properties: SLES 28 is an excellent surfactant. It has both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, which make it effective at emulsifying, foaming, and cleansing.
- Foaming Agent: SLES 28 is known for its foaming properties. It is often used in shampoos, body washes, and liquid soaps to create a rich lather that helps distribute the product evenly and cleanse effectively.
- Emulsifier: It is also used as an emulsifying agent in cosmetics and personal care products. It helps mix oil and water-based ingredients to create stable and uniform formulations.
- Cleaning Agent: SLES 28 is used in various household cleaning products, including dishwashing detergents and laundry detergents, to remove grease, stains, and dirt from surfaces.
- Skin and Hair Care: In skincare and haircare products, SLES 28 can help remove sebum, dirt, and pollutants from the skin and hair, leaving them clean and refreshed. However, it can be drying for some individuals, so it’s often used in combination with other milder surfactants and conditioning agents.
- Safety Considerations: SLES 28 is generally considered safe when used as directed in cosmetic and cleaning products. However, some people with sensitive skin may experience dryness or irritation with products containing high concentrations of SLES. In such cases, it’s advisable to use products with lower concentrations or choose sulfate-free alternatives.
- Environmental Impact: The production and disposal of SLES 28 can have environmental implications. It’s important for manufacturers to use sustainable sourcing practices and for consumers to dispose of products containing SLES properly.
- Regulation: SLES 28 is regulated in many countries, and its use in cosmetics and cleaning products is subject to various safety and labeling requirements.
- Labeling: When listed on product labels, it may appear as “Sodium Laureth Sulfate” or “Sodium Lauryl Ether Sulfate.”
In summary, SLES 28 is a versatile surfactant commonly used in personal care and cleaning products due to its foaming and cleansing properties. While it is generally safe for most people, individuals with sensitive skin may want to be cautious and opt for products with lower concentrations or sulfate-free alternatives. Always follow the usage instructions on product labels for the best results and safety.
