Description
Introduction
SLES paste-Sodium Lauryl Ether Sulfate 70% is a widely used and effective anionic surfactant in the formulation of cleaning products, personal care products, and cosmetics. It is derived from natural or synthetic fatty alcohols and ethylene oxide, making it a popular choice for those seeking plant-based and renewable ingredients.
SLES is known for its exceptional cleansing ability, high foaming capacity, and compatibility with various other ingredients, making it a versatile and essential component in a wide range of cosmetic and cleaning formulations.
SLES is classified as an anionic surfactant, meaning it has a negatively charged hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. This structure allows it to effectively interact with both water and oil, enabling the removal of dirt, grease, and other impurities from surfaces.
SLES is typically produced through the ethoxylation of fatty alcohols derived from natural sources such as coconut or palm kernel oil. The manufacturing process can involve the use of ethylene oxide, which requires careful handling due to its potential hazards.
Sodium Laureth Sulphate is considered SAFE by EWG (Environmental Working Group) as rating it EWG 1-3. Products with this ingredient are allowed for use in EWG VERIFIED but must meet use restrictions and warnings based on EWG review of company data. Only concern is for Industry or government recommendations for safe use: restrictions on concentration, impurities, product types, or manufacturing methods, if any.
SLES is widely regulated and approved for use in personal care and cleaning products by regulatory authorities such as the U.S. Food and Drug Administration (FDA) and the European Union’s Cosmetics Regulation. It undergoes rigorous safety evaluations to ensure its suitability for consumer use.
Regarding its environmental impact, SLES is readily biodegradable under aerobic conditions and is considered environmentally friendly when used responsibly and in appropriate concentrations.
Sodium Lauryl Ether Sulfate 70% is a fast dissolving surfactant & the paste form concentration reduces freight charges and Storage Rent ultimately reduces CO2 emissions. Use for Enzyme stability & stain removing performance is enhanced with the use of SLES in the formulation.

Personal care, Beauty & Cosmetics
SLES is employed in various Personal Care, Beauty & Cosmetics products because of its excellent properties. Products like:
Bubble Baths: SLES is used in bubble baths to create rich and long-lasting bubbles, enhancing the bathing experience.
Liquid Soaps: SLES is a common ingredient in liquid soaps, contributing to their cleansing and foaming properties.
Shampoos and Body Washes: SLES is widely used in shampoos, body washes, and shower gels for its ability to create a luxurious foam, lather and effectively removing dirt, oil, and impurities from hair and skin.
Facial Cleansers: It is utilized in facial cleansers to remove dirt, oil, and impurities from the skin.
Hand Soaps: SLES is a common ingredient in liquid hand soaps for its cleansing and foaming abilities.
Cosmetics: It can be found in certain cosmetics, such as creams, lotions, and makeup removers, for its emulsifying and cleansing properties.
Properties
Foaming and Emulsifying Agent: SLES is highly valued for its ability to create abundant foam, making it ideal for various cleaning applications. The foam helps to lift and suspend dirt particles, improving the overall cleaning efficiency. Additionally, SLES acts as an emulsifying agent, enabling the mixing of oil and water-based ingredients in formulations such as creams and lotions.
Compatibility and Synergy: SLES exhibits good compatibility with a wide range of ingredients, including other surfactants, builders, and preservatives. It can enhance the performance of formulations when combined with other cleaning agents or functional ingredients. This compatibility and synergy make it a versatile ingredient in the development of cleaning and personal care products.
Mildness and Skin Compatibility: Although SLES is an effective cleanser, it can be relatively milder compared to other surfactants like Sodium Lauryl Sulfate (SLS). The addition of ethylene oxide to the fatty alcohol during the manufacturing process increases its water solubility and reduces its potential for skin irritation.
However, it is important to note that individual sensitivities may vary, and certain individuals may still experience mild irritation or dryness with high concentrations or prolonged exposure to SLES.
Precautions
While the SLES paste-Sodium Lauryl Ether Sulfate 70%Â Surfactant is a safe and effective ingredient, it is essential to observe some precautions during handling and use:
- Eye Contact: In case of accidental eye contact, rinse thoroughly with water and seek medical attention if irritation persists.
- Skin Sensitivity: Some individuals with sensitive skin may experience mild irritation. If irritation occurs, discontinue use and consult a healthcare professional.
- Keep Out of Reach of Children: Store the product in a secure location away from children’s reach to prevent accidental ingestion or misuse.
- Storage: Store the surfactant in a cool, dry place away from direct sunlight and heat sources to maintain its stability and effectiveness.
- Compatibility Testing: Before incorporating the surfactant into formulations, conduct compatibility tests with other ingredients to ensure product stability and performance.
Embrace the cleansing and foaming power of SLES in your personal care and cleaning formulations.
