The Dirty Dozen: Sodium Laureth Sulfate

Sodium lauryl sulfate (SLS), a related detergent used in cosmetics, is a skin, eye and respiratory tract irritant and toxic to aquatic organisms. vii. Other ethoxylates may be contaminated with ethylene oxide and 1,4-dioxane. These ingredients usually have chemical names including the letters "eth" (e.g., sodium laureth sulfate). Get price

How does sodium sulfate react in water?

Jun 16, 2018Since H₂O and HOH are equalivent, we see that Na will take the first H's spot and create NaOH and SO₄ will take the spot of OH and create H(SO₄)OH, or H₂SO₄. Thus, the un-balanced equation is: Na₂SO₄ + H₂O -- NaOH + H₂SO₄. Balancing this equation Get price

Membranes

Figure 4 shows the retention of sulfate with a feed concentration of 0.1 mol L −1 sodium sulfate. As can be seen in the performed experiments, the retention of sulfate in aqueous solution was lower than 0.8 for permeate fluxes lower than 30 kg m − 2 h −1. At higher fluxes, the sulfate retention was in the range specified by the supplier. Get price

Why Are Sulfates in Hair Products Bad?

What Are Sulfates? Sulfates are an additive to cleaning products that causes the foaming action commonly associated with soaps. The most common sulfate is sodium lauryl sulfate (SLS), found in most shampoos and conditioners 7.
