SODIUM LAURYL SULPHATE 92%
Sodium dodecyl sulfate (SDS)
Sodium lauryl sulfate (SLS) is a widely used surfactant, which means it has the ability to reduce the surface tension of water, helping to create foam and allowing oils and dirt to mix with water so they can be rinsed away.
Chemical Composition:
- Chemical Formula: C₁₂H₂₅NaO₄S
- Structure: SLS is an organic compound made up of a 12-carbon long chain (derived from lauric acid, which is found in coconut and palm oils) attached to a sulfate group (SO₄²⁻), with a sodium ion (Na⁺) to balance the charge.
Common Uses:
-
Personal Care Products:
- SLS is found in many personal care products like shampoos, bubble baths, body washes, and facial cleansers. It’s responsible for the foaming action that helps these products clean effectively.
-
Household Cleaning Products:
- It’s also a common ingredient in household cleaning products such as detergents, dish soaps, and laundry detergents due to its ability to break down grease and dirt.
-
Industrial Applications:
- In industrial settings, SLS is used in various applications including as a detergent in textile and leather processing, as an emulsifier in insecticides, and as a foaming agent in some industrial cleaners.
Properties:
- Foaming Agent: SLS is prized for its ability to create a rich lather, which is why it’s included in many cleaning and personal care products.
- Detergent Action: It is an effective detergent, meaning it can remove oils and dirt from surfaces, including skin and hair.
- Emulsification: SLS helps to mix oil and water, stabilizing the mixture so that the product remains effective and homogeneous.
Health and Environmental Concerns:
-
Skin Irritation:
- SLS can be an irritant, especially at higher concentrations or with prolonged exposure. It may cause dryness, redness, or irritation, particularly for individuals with sensitive skin or conditions like eczema.
-
Potential for Allergic Reactions:
- Some people may have allergic reactions to SLS, though this is relatively uncommon. Reactions can include itching, redness, or rash.
-
Environmental Impact:
- SLS is biodegradable, but there are concerns about its impact on aquatic life when large quantities enter waterways. It can be toxic to fish and other aquatic organisms at certain concentrations.
-
Controversies:
- SLS has been the subject of some controversy and misinformation, particularly concerning its safety. However, it has been extensively studied and is generally considered safe for use in cosmetics and cleaning products at concentrations typically found in consumer products.
Alternatives:
- Sodium Lauryl Sulfoacetate (SLSA): A milder alternative to SLS, often used in natural or hypoallergenic products.
- Sodium Laureth Sulfate (SLES): A related compound that is milder than SLS and is also widely used in personal care products.
Summary:
Sodium lauryl sulfate is a common and effective surfactant used in a wide variety of products for its ability to clean and create foam. While it is generally safe for most people, those with sensitive skin or specific allergies may prefer to use products that are free of SLS or use milder alternatives.
