Great number of allergic reactions to sodium lauryl sulfate (6.4%) was observed." That's 15 people among 242. It is important to remember that the toxicity of a formulated consumer product is dictated by the formulation as a whole, not by the toxicity of an individual ingredient. . Ceftriaxone has a reported hypersens is aberrant immune response to any entity. Allergic reactions or sensitivity to SLS have been associated with scalp itchiness and dry, cracked, itchy or flaky skin. According to Mercola.com, most studies conducted on SLS involve feeding pure SLS to animals or applying it directly to their eyes. It is important to note, however, that potential for cross-contamination during manufacturing exists. Sodium lauryl sulfate is a surfactant ingredient that helps bind together oil and water molecules. Environmental Working Group's Skin Deep Cosmetic Safety Database: Sodium Lauryl Sulfate, Mercola: Sodium Lauryl Sulfate: Facts vs. Fairy Tales, National Institute for Occupational Safety and Health: Sodium Lauryl Sulfate, National Institute for Occupational Safety and Health: 1,4-Dioxane. Permeability. could i be absorbing it. Scientific definition: Ammonium Laureth Sulfate is the ammonium salt of sulfated ethoxylated lauryl alcohol. Lewis MA. SLS is not included on any lists of known or suspected sensitizers.33 Therefore, stating that SLS is a sensitizer is inaccurate. Follow this: Sodium Coco Sulfate is a blend of the fatty acids in coconut oil; Coconut oil is comprised of around 40 to 50% lauric acid* That means that the Sodium Coco Sulfate may actually contain 40 to 50% Sodium Lauryl Sulfate; The bottom line lies in the science. Prior to publication all authors have given signed confirmation of agreement to article publication and compliance with all applicable ethical and legal requirements, including the accuracy of author and contributor information, disclosure of competing interests and funding sources, compliance with ethical requirements relating to human and animal study participants, and compliance with any copyright requirements of third parties. For the surfactant sodium lauryl sulfate (SLS), this has resulted in a misunderstanding of the environmental health impact of the chemical and statements in the media that are not scientifically supported. Symptoms of Sulfite Sensitivity. It's used in a variety of products such as food thickeners, toothpaste, and. one of my symptoms to food allergies is that i have no energy. This ingredient's score is higher if used in products intended for use around the eyes due to increased risk of absorption. The complexity of chemical nomenclature and wide availability of scientific research provide detailed information but lends itself to misinterpretation by the lay person. Use only non-sparking tools. Warne MS, Schifko AD. Mandal K, Chakrabarti B, Thomson J, Siezen RJ. lately i have had no energy. Sulfa vs Sulfate : "sulfa allergy " is a term used to describe adverse drug reactions to the antibiotic group sulfonamide, which include septra and bactrim ( sulfamethoxazole and trimethoprim ). It also acts as an emulsifier or thickener. As far as allergies go, Nazarian says when a patient comes in with a potential contact allergy, sodium lauryl sulfate is one of the ingredients that they will test for, but it's more of an irritant than it is an allergy. 1500) requires consumer product manufacturers to perform irritation tests that appropriately characterize the ocular toxicity of the product.12 Manufacturers are required to label the product with the appropriate warnings and first aid information according to the mandatory labeling requirements of the CPSC.12. The Cosmetic Ingredient Review reports that SLS, SLES and ALS are irritants at concentrations of 2 percent or greater, and recommends that cosmetic products should not contain concentrations greater than 1 percent. Madsen T, Boyd HB, Nyln D, Pedersen AR, Petersen GI, Simonsen F. Environmental and Health Assessment of Substances in Household Detergents and Cosmetic Detergent Products. The biobased content of an ingredient is a primary criterion for formulating sustainable consumer products. The study38 in no way suggests that SLS is responsible for, or contributes to, chronic hair loss. Anionic Surfactants: Biochemistry, Toxicology, Dermatology. Because there are cases (me included) where SLS causes skin irritation, or contact allergy. According to Barbag Dental, a "basic brand of toothpaste contains sodium monofluorophosphate, glycerin, hydrated silica, water, sodium bicarbonate, PEG-12, sodium lauryl sulfate, sodium hydroxide . Dr. Nayla Mumneh and another doctor agree. Several different compounds can be used for foaming effect in SLS-free toiletries. 1500; 2015. Cosmetic Ingredient Review (CIR) Final report on the safety assessment of sodium lauryl sulfate and ammonium lauryl sulfate. Even in large quantities, sulfites usually don't cause problems in people without allergies and asthma. By using our website, you consent to our use of cookies. As of 2015, no scientific evidence has been produced to suggest that dermal exposure to SLS causes hair loss. FUNDING: JLMs work as a scientific writer for this manuscript was funded by Seventh Generation. Consult your doctor for advice regarding any new allergy symptoms. One example of an irritant agent is sodium lauryl sulfate (SLS), a detergent that has been extensively studied with regard to causing irritant contact dermatitis. Lammintausta K, Maibach HI, Wilson D. Irritant reactivity on males and females. Symptoms of an allergic reaction to sulfa drugs include rash or hives, itchy skin or eyes, and swelling.. SLS that is absorbed into the bloodstream is quickly metabolized by the liver into more water-soluble metabolites that are rapidly excreted through the urine, feces, and sometimes expired breath.1,22,23,37 There is no evidence in the CIR report or in the scientific literature at large that supports the accumulation of SLS in vital organs and associates it to systemic toxicity or vital organ damage.22,23,33 As such, accusations that SLS will bioaccumulate in humans and cause organ damage are inaccurate. If you are concerned about the possible effects of SLS accumulation, look for shampoos, toothpastes and other personal care products marked "SLS free." Few researchers say that products that include SLS have carcinogenic agents, which can trigger cancer. Non-irritant baby shampoos may cause cataract development. Furthermore, it should be noted that the anatomy of the eye renders direct exposure of the lens to SLS impossible, as it is deep within the eye protected by the cornea, and therefore, not vulnerable to exposure through typical consumer product usage.22,23 As such, a causal relationship between SLS in consumer products and cataract formation is not scientifically supported. Firstly, the European Chemicals Agency (ECHA) classifies SLS as: "harmful if swallowed, causes serious eye damage, is harmful to aquatic life with long lasting effects, is a flammable solid, is harmful if inhaled, causes . i am allergic to sulfa and i need to know if my shampoo and body wash are causing me problems. While concentrated SLS is useful as an experimental irritant, this is not relevant to evaluating human exposure to SLS in household cleaning products. You may switch to Article in classic view. would this allergy mean i am allergic to sodium laureth sulfate found in body wash? It is concluded that the use of SLS in cleaning product formulations does not introduce unnecessary risk to consumers or the environment because of the presence of the ingredient, and, if properly formulated and qualified, does not pose danger to human health and safety. Like most chemicals, SLS can be irritating to the eye when delivered neat as a raw material or at high concentrations. If you are allergic to sulfa there is a small cross reactivity to sulfate. Chronic skin ailments like contact dermatitis and eczema can be triggered by repeated use of products that include sodium lauryl sulfate. This ingredient's score is higher if used in products that are inhalable (e.g., sprays, powders) because of respiratory concerns. Exposure of this sort is not ordinarily experienced through normal cosmetic use. From a sustainability and environmental health perspective, sourcing surfactants such as plant-derived SLS avoids incurring the additional environmental and human health impacts caused by the extraction of petroleum and the production of petrochemicals. contact or inhalation, allergy has not been described. Griffith JF, Nixon GA, Bruce RD, Reer PJ, Bannan EA. Sodium Lauryl Sulfate (SLS): . CAMB conceived and designed the review and wrote the first draft of the manuscript. This compound is the sodium salt of the 12-carbon an organosulfate. Topical application of cosmetic products allows these chemicals to penetrate deep into the skin and absorbed by blood stream. When purchased online. International Agency for Research on Cancer (IARC). Piret J, LaForest G, Bussires M, Bergeron MG. Subchronic (26- and 52-week) toxicity and irritation studies of a novel microbicidal gel formulation containing sodium lauryl sulfate in animal models. It sometimes goes by other names, including sodium dodecyl sulfate and sodium laureth sulfate. Other claims denouncing SLS as a carcinogen point to a chemical reaction between SLS and formaldehyde that creates nitrosamines as a by-product.32 However, it is not possible for SLS and formaldehyde to react and form a nitrosamine. According to the Environmental Working Group's Skin Deep Cosmetic Safety Database, SLS is a "moderate hazard" that has been linked to cancer, neurotoxicity, organ toxicity, skin irritation and endocrine disruption. 1216. Sodium Coco Sulfate contains Sodium Lauryl Sulfate. from www.shutterstock.com. In the pharmaceutical industry, it has been used as an excipient in dissolvable dosage forms. This holds true for the use of SLS in food products as well and explains why SLS is listed on the U.S. Food and Drug Administration (FDA) list of multipurpose additives allowed to be directly and indirectly added to food.30 Note, too, that every chemical has a toxic dose, and many common foods can be classified as toxic. "Anything can be an irritant if it's used the wrong way or if it's on the skin too long," she explains. But, can lead to other allergic reactions. You did not describe your type of allergy but i Can you please clarify your allergy. 1Research and Development, Seventh Generation Inc., Burlington, VT, USA. Your patch testing results indicate that you have a contact allergy to Sodium Lauryl Sulfate. Here, we review the human and environmental toxicity profiles of SLS and demonstrate that it is safe for use in consumer household cleaning products. The only way to make sure a product contains no SLS is to read the entire ingredient list. Controversy regarding the use of SLS in toiletry products centers upon the potential for allergic reactions, and the presence of certain carcinogenic compounds in products which contain SLS. It is used in industrial strength degreasers, floor cleaners, bubble bath and toothpastes. But does it actually damage the tissue? Therefore, the two cannot react to form a nitrogen-containing nitrosamine. Ocular irritation has been induced in vivo using SLS concentrations equivalent to a rinse-off personal care product containing 20% SLS.17 However, this was achieved after the eyes of laboratory animals were repeatedly exposed to 0.5 mL of shampoo for 14 days.17 While 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. Sulfa allergy and allergy to sulfites found in food or drink aren't the same thing. Science-based formula - Our plant-derived formula is made with sniffing deliciously pure essential oils and USDA certified organic surfactants that clean and protect delicate clothing; Free from Sulfate harsh chemicals, toxins, dyes, phthalates, and parabens. Researchers simply applied some SLS at the concentration found in toothpaste onto someone's gums with a Q-tip for 90 seconds and measured the spike in blood flow to the area, a sign of inflammation, presumably because the detergent was penetrating and irritating the gums, as you can see at 3:06 in my video. They don't list SLS as a cancer risk, however, they do list it as high concern for irritation of the skin, eyes, and lungs; a moderate concern for non-reproductive organ toxicity, and a low concern for ecotoxicology (harmful to the environment). Sodium lauryl sulfate is one such chemical substance, which can irritate your skin. But between 3% and 10% of people with asthma see their symptoms increase after sulfite exposure. Chronic and sublethal toxicities of surfactants to aquatic animals: a review and risk assessment. For this reason, many Sensodyne toothpastes are formulated without SLS, to keep your teeth clean and healthy without causing further sensitivity. SLS may make your skin sensitive even if it wasn't sensitive before. Sodium lauryl sulfate (SLS) is a surfactant, which basically means it has an effect on the surfaces it touches. No Action should be taken solely on the contents of this Website. Additives Sulfates- If you've read the "sulfate-free" labels on shampoo bottles, that is because sulfatessuch as sodium lauryl sulfate (SLS) and sodium laureth suflate (SLES) can be harsh . Sodium lauryl sulfate (SLS) is an anionic surface active agent commonly used in cosmetics. According to Environmental Working Group (EWG) 1 in 5 cosmetic products may contain cancer causing agents. What is the definition or description of: dalteparin sodium allergy? Robinson, et al. ; May/June 2001, Mother Nature Network; Safe Shampoo? A study published in 1998 by the European Journal of Dermatology is also cited as supporting claims that SLS causes hair loss.38 This study investigates the effects of oxidative stress on skin irritation and uses SLS as an experimental irritant. For the surfactant sodium lauryl sulfate (SLS), this has resulted in a misunderstanding of the environmental health impact of the chemical and statements in the media that are not scientifically supported. The functionality is limited to basic scrolling. The findings presented by Green et al.14 do not suggest that ocular exposure to consumer products containing SLS causes blindness or severe damage to the cornea. Where you'll find SLS If you look under your bathroom sink,. Zheng YJ, Chen L, Chen YP, Huang R. Acute toxicity of sodium dodecyl sulfate (SDS) on selected aquatic organisms. Sodium coco sulfate, a coconut derivative, has a foaming action without the potential for formation of the carcinogenic chemical 1,4-dioxane. Dahl M, Trancik RJ. We are experimenting with display styles that make it easier to read articles in PMC. one of my symptoms to food allergies is that i have no energy. All editorial decisions made by independent academic editor. Actives ingredients: Strengthening horsetail, Conditioning coconut oil, Soothing chamomile, Biodynamic nettle for scalp health, Shine-promoting rosemary and Moisture-locking aloe vera juice. A second erroneous ocular health claim made about SLS is its link to cataract formation.16,17 Claims about SLS causing cataract formation tend to cite a 1987 study in the Journal of Biological Chemistry.18 This study18 along with several others1921 uses SLS to model cataract formation experimentally. According to United Nations Environmental Programme, approximately 70,000 chemical are incorporated in daily used cosmetic products. Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. De Jongh CM, Verberk MM, Spiekstra SW, Gibbs S, Kezic S. Cytokines at different stratum corneum levels in normal and sodium lauryl sulphate-irritated skin. Ecotoxicity studies have determined that a surfactant concentration of 0.5 mg/L of natural water would be essentially nontoxic to fish and other aquatic life under most conditions.42 It is suggested, however, that chronic toxicity of anionic surfactants occurs at concentrations as low as 0.1 mg/L.40. Massaging with olive oil, coconut oil or jojoba oil will relieve from rigorous itching. In the study by Birt et al.35, SLS was used as a vehicle to process the agent being tested. It is an anionic surfactant used in many cleaning and hygiene products. A comprehensive safety assessment published in the International Journal of Toxicology deemed that sodium lauroyl sarcosinate was not expected to be potentially toxic or harmful, and had no mutagenic . Material Safty Data Sheet: STEPANOL WA-EXTRA K. Sodium Dodecyl Sulfate (CAS151213) MSDS. But, when sensitive skin people use these chemical ingredient items, substances like SLS can irritate the skin. Ammonium lauryl sulfate, or ALS, is similar to SLS and poses similar risks. 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. Apart from that you must avoid products that have SLS chemical incorporated in it.
