Sodium lauryl ether sulfate (SLES), also called AES or sodium laureth sulfate, is the white or light yellow viscous paste in appearance. It is an anionic surfactant, easily soluble in water. It has excellent decontamination, emulsifying, wetting, dispersing, thickening and foaming properties, and at the same time, sodium laureth sulfate is also a good emulsifier. SLES 70% can be used in combination with other anionic, nonionic or amphoteric surfactants. However, due to its anionic character, SLES sodium laureth sulfate should not be used with cationic components such as cationic surfactants, cationic dyes.
As an anionic detergent and surfactant, sodium lauryl ether sulfate (SLES 70) is widely used in many personal care products such as soaps, shampoos and toothpastes due to its broad compatibility, good hard water resistance, high biodegradability and low irritation to skin and eyes. And SLES sodium lauryl ether sulfate 70 can be used in moisturizing formulations, liquid detergents, cleansers, shampoos and laundry detergents. In addition, SLES 70% can be used in many cosmetics for its cleansing and emulsifying properties.

Applications of Sodium Lauryl Ether Sulfate SLES 70%
The SLES 70% liquid has excellent detergency, emulsification and fiamability. So it can be widely applied in hair shampoo, bath shampoo, dish detergents and complex soap. Besides, SLES is also used in wetting and clearer in textile industry.
(1) Personal care products
Shampoo. The sodium lauryl ether sulfate provides excellent foaming and detergency, helping to effectively clean grease, dirt and dandruff from the hair and scalp, making the hair more refreshing and easy to manage.
Shower gel. SLES 70 % can produce rich foam and help remove dirt and grease from the skin surface, making the skin feel refreshed and moisturized.
Facial cleanser. This chemical is also commonly used in facial cleansers. Its gentle and effective cleaning ability helps to penetrate deep into the pores, remove grease, dirt and makeup residue, and keep the skin clean and transparent.
(2) Household cleaning products
Laundry detergent. SLES 70 is widely used in laundry detergent. Its strong detergency can quickly decompose stains on clothes. At the same time, its emulsifying properties make clothes easier to rinse and improve the laundry effect.
Detergent. Sodium laureth sulfate 70% is also the main surfactant in dishwashing liquid. Its excellent degreasing and decontamination performance can effectively clean tableware and kitchen surfaces, keeping the kitchen clean and hygienic.
Floor cleaner. In floor cleaners, SLES 70 can remove stains and grease on the ground while maintaining the gloss and anti-slip properties of the floor.
(3) Industrial use
SLES 70 is used as an auxiliary agent in the textile industry to improve the feel and softness of textiles, and improve the hydrophilicity and antistatic properties of fabrics.
Sodium laureth sulfate can also be used in the formulation of metal cleaners, which can quickly decompose and remove oil, dirt and rust on the metal surface, keeping the metal clean and smooth.
(4) Foam products. Due to its excellent foaming properties, SLES 70 is also often used to make foam products, such as foam hand soap, foam cleanser, etc., providing a rich and delicate foam experience.
Performance Characteristics of SLES 70%
The sodium laureth sulfate (SLES 70) is a surfactant widely used in personal care and household cleaning products. The following is an introduction to the main performance characteristics of SLES 70:
(1) Excellent Decontamination Ability. SLES 70 can effectively break down and remove various oils, dirt and impurities, providing a refreshing and clean feeling to the skin. Its application in personal care products such as shampoo and shower gel enables it to quickly remove oil and dirt from hair and skin.
(2) Excellent Emulsification Performance. As a surfactant, sodium lauryl ether sulfate 70% has excellent emulsification ability. It can mix and stabilize two immiscible liquids, water and oil, to form an emulsion that is easy to rinse. This makes SLES 70 play an important role in products such as skin creams and lotions, helping water and oil to mix better, thereby providing a longer-lasting moisturizing effect.
(3) Good Foaming Performance. SLES sodium lauryl ether sulfate has good foaming performance and can quickly produce rich and delicate foam in water. These foams can better wrap and remove stains, making the cleaning process more efficient. In products such as shampoo and shower gel, the foaming performance of SLES 70 not only improves the product’s usage experience, but also helps to deeply clean the hair and skin.
(4) Hard water resistance. Calcium and magnesium ions in hard water often react with surfactants to form precipitates, which affects the cleaning effect of surfactants. However, SLES 70 has a certain resistance to hard water and can maintain stable cleaning performance even under hard water conditions. This allows SLES chemical to work well under various water conditions.
(5) Good biodegradability. The SLES chemical is a biodegradable surfactant that can be decomposed into non-toxic or low-toxic substances by microorganisms in the natural environment. This feature makes SLES 70 an environmentally friendly surfactant choice that helps reduce the impact on the environment.
(6) Mild irritation. Although SLES 70 may cause slight irritation to some sensitive skin, its irritation is relatively low compared to other surfactants. Through reasonable formula design and product optimization, the irritation of SLES chemical to the skin can be reduced, making it more suitable for sensitive skin.
(7) Excellent compatibility. The sodium lauryl ether sulfate 70% is compatible with a variety of raw materials and additives and has good compatibility. This gives it great flexibility in formula design and allows it to be formulated and optimized according to product needs.
(8) Stable chemical properties. This chemical has stable chemical properties during storage and use and is not prone to decomposition or deterioration. This makes it more reliable and convenient during production and use.
