Is sodium dodecylbenzene sulfonate toxic?
Detergent. Sodium dodecylbenzene sulfonate is a yellow oil, which can form a hexagonal or rhombic strong flake-like crystal. It has micro toxicity and has been recognized by the international security organization as a safe chemical raw material.
Is sodium dodecylbenzene sulfonate safe?
Abstract. Sodium dodecylbenzenesulfonate is one of a group of salts of alkylbenzene sulfonates used in cosmetics as surfactant-cleansing agents. Dodecylbenzenesulfonate salts are not toxic in single-dose oral and dermal animal tests, and no systemic toxicities were observed in repeat-dose dermal animal studies.
What is sodium dodecylbenzene sulfonate used for?
Sodium dodecylbenzene sulfonate is a cleaning agent, or “surfactant,” that is one of a group of ingredients commonly used in bath products, cleansing products, shampoos and hair conditioners. We use it in our products to remove dirt and deposits.
Is sodium dodecylbenzenesulfonate a disinfectant?
Sulfates. Sulfates are a multi-purpose disinfectant. They consist of potassium peroxymonosulfate, sodium dodecylbenzenesulfonate, sulfamic acid and inorganic buffers. They are typically used for cleaning up hazardous spills, disinfecting surfaces and rinsing equipment.
Is sodium dodecylbenzene sulfonate biodegradable?
Conclusions: Biodegradation of sodium dodecylbenzene sulfonate (DBS), at 10 ppm was measured 75% after 11 days and test temperature was maintained at 20 deg C for 17 days. The sodium dodecylbenzene sulfonate (DBS) could be conclued as readily degradable.
Is SDS toxic?
Toxicity Contains a substance (SDS) which is toxic to aquatic organisms.

All Answers (8) No, SDS is a strong electrolyte and it must not be pH sensitive.
What are the side effects of sodium lauryl sulfate?
The highest risk of using products with SLS and SLES is irritation to your eyes, skin, mouth, and lungs. For people with sensitive skin, sulfates may also clog pores and cause acne. Many products have a lower concentration of SLS or SLES in their formulation.
Does SDS dissolve in water?
This product is soluble in water (200 mg/ml), yielding a clear, colorless solution. SDS undergoes hydrolysis at elevated temperatures, especially in acidic medium.
How do you get 10 SDS?
How to make 10% SDS stock solution
- Weigh out 10 g SDS and add to a 100 mL Duran bottle.
- Measure out 80 mL of distilled water and add to the Duran bottle.
- Add a magnetic flea and place on a magnetic stirring plate to mix the solution.
- Once the power has fully dissolved, top up the solution to 100 mL using distilled water.
What is SDS surfactant?
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is a synthetic organic compound with the formula CH3(CH2)11SO4Na. It is an anionic surfactant used in many cleaning and hygiene products. This molecule is an organosulfate and a salt.
How do you make a 20% SDS?
Also called sodium dodecyl sulfate or sodium lauryl sulfate. To prepare a 20% (w/v) solution, dissolve 200 g of electrophoresis-grade SDS in 900 mL of H2O. Heat to 68°C and stir with a magnetic stirrer to assist dissolution.

What is SDS solution?
SDS Solution (10% w/v) is sodium dodecyl sulfate in distilled, deionized water. SDS is a detergent that is known to denature proteins. It is used in polyacrylamide gel electrophoresis for the determination of protein molecular weight.
How do you create a safety data sheet?
Steps to writing an SDS
- Review OSHA requirements (29 CFR 1910.1200; Guidance for Hazard Determination)
- Use OSHA short form or ANSI format.
- Review Sigma or other manufacturer’s SDSs for similar products.
- Use established Risk and Safety Statements (see Sigma printout).
- Include TSCA R&D exemption wording.
Who can create a safety data sheet?
The MSDS is a detailed informational document prepared by the manufacturer or importer of a hazardous chemical. It describes the physical and chemical properties of the product. MSDS’s contain useful information such as flash point, toxicity, procedures for spills and leaks, and storage guidelines.
What is the difference between SDS and MSDS?
There is no difference between an MSDS and an SDS, as both are generic terms for safety data sheets. A GHS compliant safety data sheet is an SDS but not an MSDS. An SDS can be an MSDS, but an MSDS is not an SDS. And calling a document an SDS does not make it GHS compliant.
