Ought to You Keep away from Disodium Laureth Sulphosuccinate?

What is disodium laureth sulfosuccinate?

Disodium Laureth Sulfosuccinate, or DLS, is a cleansing ingredient used to improve the cleanability of skin care products. It is generally considered to be less harsh than other cleaning ingredients such as sulfates.

DLS is a common ingredient in shampoos, detergents, and body washes. This is mainly due to its ability to remove oils and dirt from the skin so that it can be easily rinsed off. DLS also helps improve the foaming of the product and stabilize the product.

DLS is not considered a sulfate, while the name sulfates such as Sodium lauryl sulfateIt is considered to be far gentler on the skin and not irritating.

the good: DLS is a surfactant that helps cleanse the skin, remove dirt, and remove oils so they can be washed off.

not that good: DLS is considered safe and is generally considered to be gentler than other surfactants.

For whom is that? All skin types except those identified as having an allergy.

Synergetic ingredients: Works well with most ingredients.

Keep an eye on: There is nothing to observe here.

Why is disodium laureth sulfosuccinate used?

Disodium laureth sulfosuccinate is a surfactant. Surfactants lower the surface tension between two liquids or solids. This allows oils and dirt to be removed from the skin and easily washed off the skin. For this reason, DLS is mainly used in detergents, soaps, bubble bath products, shampoos and shaving creams.

DLS is considered to be gentler on the skin. This is due to the molecular size, other surfactants have smaller molecular sizes, while DLS has a comparatively larger molecular size. This means that DLS does not easily penetrate the skin where irritation is likely to occur. It’s also a negatively charged molecule that contributes to its milder nature.

You can often find DLS in products that claim to be sulfate-free. Sulfate-free products have become popular with the advent of clean beauty and are often preferred because they can be less irritating. However, without sulfates, detergents and detergents must use a different surfactant to be effective at cleaning. This may mean using a harder surfactant than sulfates to still fit the “sulfate free” label. This is where DLS is a good option as it is not considered a sulfate but is still a milder option when formulating a sulfate-free product.

Is Disodium Laureth Sulphosuccinate Safe?

The security of DLS was supported by the Expert panel for the review of cosmetic ingredients, a group responsible for evaluating the safety and effectiveness of skin care and cosmetic ingredients.

The panel of experts indicated that DLS in its current uses and concentrations is considered safe when formulated as non-irritating. Due to its high molecular weight and negative charge, it does not penetrate the skin and poses little health risk. The panel of experts also noted that DLS is not considered a sensitizer but can cause skin and eye irritation, particularly if the product is not formulated to minimize irritation.
