How long does SLS exposure last?
Dermal toxicity studies demonstrate that 24-hour exposure to a 1–2% (w/w) solution of SLS can increase the transepidermal water loss of the stratum corneum – the outer most layer of the skin – and cause mild yet reversible skin inflammation.24,25Human patch tests (typically a 24-hour exposure) confirm that SLS concentrations >2% are considered irritating to normal skin.2,26,27Dermal irritation also tends to increase with SLS concentration and the duration of direct contact.2In reality, dermal exposure to SLS in cleaning products is more likely to last a matter of minutes rather than hours.9
How does SLS decompose?
The ability of a chemical to decompose into simple, nontoxic components under ambient environmental conditions within a short period of time (typically 96 hours) means that it is biodegradable. SLS is readily biodegradable under aerobic and anaerobic conditions and, therefore, does not persist in the environment.8,37,45The biodegradation of SLS occurs via hydrolytic cleavage of the sulfate ester bond leaving inorganic sulfate and fatty alcohol. These fatty alcohols undergo oxidation to produce fatty acids, which are degraded by β-oxidation and fully mineralized and incorporated into the biomass.45Thus, the decomposed by-products of SLS are benign to the environment.
What is SLS in cleaning products?
Sodium lauryl sulfate (SLS), also known as sodium laurilsulfate or sodium dodecyl sulfate, is an anionic surfactant commonly used as an emulsifying cleaning agent in household cleaning products (laundry detergents, spray cleaners, and dishwasher detergents). The concentration of SLS found in consumer products varies by product and manufacturer but typically ranges from 0.01% to 50% in cosmetic products1,2and 1% to 30% in cleaning products.3,4SLS can be synthetic or naturally derived. This chemical is synthesized by reacting lauryl alcohol from a petroleum or plant source with sulfur trioxide to produce hydrogen lauryl sulfate, which is then neutralized with sodium carbonate to produce SLS.5
What is aquatic toxicology?
Aquatic toxicity refers to the short-term adverse effects that result from the exposure of aquatic life to a chemical or formulation. This type of toxicity is measured in terms of the median lethal concentration (LC50), which indicates the quantity by volume (typically reported as milligrams of substance per liter of water) required to kill half of the experimental population exposed to that dose. Ingredients or formulations with an LC50of ≥100 mg/L are classified as nontoxic to aquatic life.39
Is sodium lauryl sulfate toxic?
Human and Environmental Toxicity of Sodium Lauryl Sulfate (SLS): Evidence for Safe Use in Household Cleaning Products
Does SLS cause cataracts?
A second erroneous ocular health claim made about SLS is its link to cataract formation.16,17Claims about SLS causing cataract formation tend to cite a 1987 study in the Journal of Biological Chemistry.18This study18– along with several others19–21– uses SLS to model cataract formation experimentally. In a controlled laboratory environment, cataract formation can be induced by immersing the lens of the eye in a concentrated solution of SLS. While concentrated SLS is useful as an experimental irritant, this is not relevant to evaluating human exposure to SLS in household cleaning products. Ocular irritation has been induced in vivousing SLS concentrations equivalent to a rinse-off personal care product containing 20% SLS.17However, this was achieved after the eyes of laboratory animals were repeatedly exposed to 0.5 mL of shampoo for 14 days.17While SLS is useful in studying the formation and repair of cataracts in laboratory settings, studies of this nature are not appropriate for assessing the risk of human exposure to SLS in cleaning products.
Is SLS a raw material?
Like most chemicals, SLS can be irritating to the eye when delivered neat as a raw material or at high concentrations. At concentrations <0.1% (w/w), SLS is nonirritating to the eyes of laboratory animals.1For this reason, it is imperative for consumer product manufacturers to test finished products for ocular irritation. The U.S. Consumer Product Safety Commission (CPSC;16 C.F.R. §1500) requires consumer product manufacturers to perform irritation tests that appropriately characterize the ocular toxicity of the product.12Manufacturers are required to label the product with the appropriate warnings and first aid information according to the mandatory labeling requirements of the CPSC.12
