Suppose you are familiar with the beauty products used in everyday life. In that case, you are sure to come across sodium Laureth sulfate, a detergent and surfactant found in various personal care products. Read the points below to hone your knowledge.

  • Sodium lauryl sulfate or SLS may cause skin irritation, has low aqueous solubility, and cannot make the cosmetic formulation thick.
  • Due to the limitations of SLS, it has now been taken over by SLES or Sodium Lauryl Ether Sulfate.
  • SLES is one of the most noted ingredients of several household products, from shampoo to dishwashing liquid. 
  • SLES does not cause as much skin irritation as SLS or shows less insensitivity to hard water. 
  • The compound has reasonably good properties, is affordable, and is readily available everywhere. 
  • For manufacturing household products, SLES 70 is the more prominent option to use.
  • SLES comes from SLS through ethoxylation, making the former safe for body care products and bathing ingredients.
  • Compared to sodium lauryl sulfate, SLES is more suitable for foaming, cleansing, and emulsifying and leaves the skin feeling soft, nourished, and smooth. 
  • The combination of SLES with other skin-friendly ingredients produces high-quality skincare and personal products. 

When Exploring the Features of SLS or SLES, You Need to Note the Following.

  • Soap
  • Shampoo
  • Washing liquid
  • Toothpaste
  • Mouthwash
  • Bubble bath
  • Moisturizer
  • Sun creams and several other personal care products. 

Manufacturing SLES:

SLES is prepared or manufactured through ethoxylation of dodecyl alcohol and industrially produced from coconut or palm kernel oil. The ethoxylate that forms converts into half ester in sulfuric acid, which neutralizes through the conversion to sodium salt. The surfactant SLS or sodium lauryl sulfate follows the same steps except for the ethoxylation step.

Manufacturing Liquid Detergent:

The liquid detergent is a synthetic cleaning agent but different from liquid soap. There are several different ingredients required in liquid detergents. The SLES detergents are highly popular due to their capacity to cut grease. 

  • You need to take hot water in a bowl and dissolve SLES until it dissolves fully.
  • You need to add betaine, EDTA, citric acid, and preservatives to prepare a mixture.
  • After this, you need to add salt and leave the mixture overnight for the suds to clear.
  • In the final step, add color and fragrance to the taste. 
  • Pour the liquid detergent into the container. 


The SLS and SLES are two of the most important ingredients of personal care products. Typically, SLES is a less harsh version of SLS and manufactured through a process called ethoxylation. Both are foaming agents, produce many bubbles and foam, and are popularly used in bathroom products that require foam. For instance, bubble bath and shaving foam are some of the products requiring SLES. 

Benefits and industry applications:

SLES has reasonably good solvency, favorable hard water resistance, and is biodegradable. It also eases the production of a formulation. 

  • It is widely used in personal and home care products, such as bubble baths, face wash, liquid detergent, and hand wash. 
  • Besides, it is also used for the petroleum and leather industry as a lubricant, cleaner, dyeing agent, and foaming agent. 
  • You can contact SLES 70 suppliers to procure high-end products. 

SLES is an ingredient used for manufacturing detergent and cosmetic products for the market. You are sure to come across SLES 70 manufacturers catering to the mass market. Various manufacturers and suppliers are offering a wide range of products of different grades. SLS and SLES are primarily used in personal care items, but they may be available in various other products that may not target a mass audience.
