Sodium lauryl sulfate (SDS) 98+%, powder, extra pure

Sodium lauryl sulfate has various applications in different fields due to its cleaning and foaming properties. Here are some of the top uses by field:

1. Personal care:

   • Shampoo and conditioner: SLS is often used as a cleanser and foaming agent in hair care products.
   • Toothpaste: It is used to foam toothpaste and to remove dirt and plaque.
   • Shower gel and soap: SLS helps remove dirt and oil from the skin and provides lather.
   • Shaving cream: It is added to shaving foam to create a rich lather.

2. Pharmaceuticals:

   • SLS can be used in some pharmaceutical formulations for oral use as a surfactant to help disperse and dissolve drugs.

3. Household cleaning products:

   • SLS is often used in cleaning products such as dish soap, floor cleaners and all-purpose cleaners because of its ability to remove dirt and grease.

4. Industrial applications:

   • In industry, SLS is sometimes used as an emulsifying agent or a foaming agent in various processes, such as in the production of polymers and plastics.

5. Textile industry:

   • SLS can be used in the textile industry as a wetting agent or a surfactant in certain dyeing and processing processes.

6. Research and development:

   • In laboratories, SLS is sometimes used as a reference material or a standard in chemical and physical studies.

It is important to note that while SLS has many uses for its cleansing properties, some people may be sensitive for SLS and may experience skin irritation with prolonged or repeated contact. Therefore, alternative surfactants are available to products that are considered gentler on the skin.

What are the chemical properties of Sodium Lauryl Sulfate?</p >

Sodium lauryl sulfate (SLS) is a surfactant with various chemical properties. Here are some of the key chemical properties of SLS:

1. Hydrophilic and hydrophobic moieties: SLS has a hydrophilic (hydroattracting) sulfate group (-SO4Na) and a hydrophobic (water-repellent) long hydrocarbon chain (lauryl chain with 12 carbon atoms). This dual nature makes SLS effective at emulsifying water and grease, which explains its cleaning ability.

2. Foam Forming: SLS is known for its excellent foam forming characteristics. It can trap air in water to create foam, which is why it is used in products such as shampoo, soap and toothpaste.

3. Solubility: SLS is good soluble in water, which is important for personal care and cleaning product applications, where it helps remove dirt and oil.

4. Surfactant properties: SLS has surfactant properties, meaning it can reduce the surface tension of liquids and bind to both water molecules and oil molecules. This allows it to loosen dirt and grease from surfaces, making them easier to rinse away.

5. Ionic nature: SLS is an ionic compound and consists of positive charged sodium ions (Na+) and negatively charged sulfate ions (-SO4). This makes it an electrolyte, meaning it can dissociate into these ions in water.

6. pH dependence: The surfactant properties of SLS are pH dependent. It is most effective at a neutral or slightly alkaline pH. In acidic conditions it may be less effective.
