Product description

Sodium Laureth Sulfate (SLES) 70% is an anionic surfactant produced from fatty alcohols of natural origin (coconut, palm oil), which is subsequently ethoxylated and sulfonated. It is a highly effective cleansing and foaming ingredient, used mainly in shampoos, shower gels, liquid soaps and cleansing preparations. Thanks to its concentrated form (70% active substance), it is ideal for industrial and artisanal cosmetic manufacturing, where it is diluted and combined with other surfactants to optimize mildness and stability. Dilution is relatively demanding; for easier handling we recommend SLES 26%.

Key benefits:

• Strong cleansing effect – effectively removes grease and impurities.

• High foamability – rich, creamy foam even at low concentration.

• Good compatibility – suitable in combination with amphoteric and non-ionic surfactants (e.g. Coco-Betaine) to reduce irritancy.

• Economical use – the concentrated form (70%) facilitates storage and handling.

• Universal use – widely used in personal care and household care.

Suitable for products such as:

• shampoos, conditioning shampoos

• shower gels, liquid soaps

• bath foams and cleansing foams

• facial and body cleansing gels

• detergents and household cleaning preparations

Use in formulation:

• Solubility: completely soluble in water.

• Dosage (indicative):

  • shampoos, shower gels, liquid soaps: 5–20% (depending on the desired mildness and foamability)

  • household cleaning products: up to 30%

• Incorporation: added to the aqueous phase under stirring; dilution before mixing with other components is recommended.

• Thermal resistance: normally stable up to 80 °C.

SLES 70% is the standard among foaming surfactants and the basis of most cleansing and washing products in cosmetics and household care.

Safety grade of the raw material according to the EWG: 3 – medium risk

FAQ

Is SLES suitable for sensitive skin?
SLES has a strong cleansing effect, so at higher concentrations it can dry out or irritate the skin. In combination with milder surfactants (e.g. Coco-Betaine), its irritancy is significantly reduced.

What is the difference between SLES and SLS?
SLES (Sodium Laureth Sulfate) contains ethoxylated chains, which makes it milder than SLS (Sodium Lauryl Sulfate), which is considered more aggressive to the skin.

Can I also use SLES in baby/children’s cosmetics?
Only at low concentrations and always in combination with milder surfactants. When manufacturing children’s cosmetics, even gentler alternatives are more often recommended.

Is SLES biodegradable?
Yes, SLES is considered readily biodegradable.
