Sodium Lauryl Sulfoacetate (SLSa): A Gentle, Sulfate-Free Cleanser for Bath and Body Care

Sodium Lauryl Sulfoacetate (SLSa) is a mild, sulfate-free anionic natural surfactant derived from coconut and palm oils, making it a safe and gentle alternative to harsher surfactants like SLS (Sodium Lauryl Sulfate). Known for producing luxurious, long-lasting foam, SLSa is ideal for formulating bath bombs, bubble bars, shampoo bars, and other foaming skincare products. This biodegradable and eco-friendly ingredient is perfect for creating products that provide gentle cleansing without stripping the skin of its natural oils.

• Luxurious Foam: SLSa creates a rich, long-lasting lather, providing an enjoyable cleansing experience in bath bombs, bubble bars, and other foaming products.
• Sulfate-Free: As a sulfate-free surfactant, SLSa is a safe alternative for those looking for gentle and natural cleansing options.
• Eco-Friendly: Derived from natural sources such as coconut and palm oils, SLSa is biodegradable and does not contribute to water pollution, making it an eco-conscious choice for formulators.
• Versatile Use: SLSa is an ideal ingredient for a variety of formulations, including bath bombs, bubble bars, solid shampoo bars, solid body wash bars, and more.

Suggested Uses

• Bath bombs
• Bubble bars
• Shampoo bars
• Solid body wash bars
• Foaming facial cleansers

Recommended Usage:

• Bath Bombs & Bubble Bars: Use 3% to 10% of the total formulation to create rich, long-lasting foam. For larger bubbles and more luxurious lather, the usage rate can be increased, but typically 3-10% provides excellent results.

• Solid Products (e.g., Shampoo Bars, Solid Body Wash Bars): For gentle, sulfate-free cleansing in solid products, use SLSa at 1% to 5%. In more concentrated products, such as solid bubble bath bars, you can use SLSa at up to 50% to 70%. It is safe and non-irritating at these higher levels, making it ideal for solid foaming cleansers.

• Liquid Foaming Products (e.g., Bath Gels, Foaming Cleansers): Use 1% to 4% in liquid products to boost foaming and enhance viscosity. For foaming bath gels, the rate can be as high as 3% to 8% for optimal foam creation.

• Powdered Products: In powder-based foaming bath products, such as bath salts or foaming bath powders, use 15% to 25% for effective foam production.

General Guidelines: Sodium Lauryl Sulfoacetate is versatile and can be used at different rates depending on the type of product you are formulating. It can be safely used up to 70% in solid and paste-like products due to its mild, non-irritating nature, making it suitable for even sensitive skin.

Why Choose Sodium Lauryl Sulfoacetate (SLSa)?

• Gentle & Safe for All Skin Types: Unlike traditional sulfates, SLSa is much milder and does not cause dryness or irritation, making it suitable for all skin types, especially sensitive skin.
• Natural & Biodegradable: Derived from coconut and palm oils, SLSa is a plant-based surfactant that’s gentle on both your skin and the environment.
• Rich Foaming Action: Known for producing luxurious bubbles, SLSa is perfect for creating bath and body products that offer an indulgent experience.
• Versatile Formulation Ingredient: Whether you’re making bath bombs, bubble bars, shampoo bars, or body wash bars, SLSa’s fine white powder form ensures it disperses easily into your formulations.

How to Use Sodium Lauryl Sulfoacetate (SLSa) in Formulations:

• Bath Bombs & Bubble Bars: SLSa adds bubbly goodness and rich, long-lasting foam to your bath bombs and bubble bars. Use 3% to 10% of SLSa in the formulation to create foam, adjusting the percentage for larger bubbles and more luxurious lather. For bath bombs, you can balance the formulation by using equal parts SLSa and citric acid. In bubble bars, use 15-20% for maximum lather, creating a product that leaves skin soft while providing ample foam.

• Shampoo Bars & Solid Body Wash Bars: Use 1% to 5% of SLSa for a gentle, sulfate-free cleanse that doesn’t strip hair or skin of their natural oils. For more concentrated formulations, like solid bubble bath bars or solid body washes, SLSa can be used at up to 50-70%. This higher usage rate ensures a luxurious, creamy lather and effective cleansing action. Pair with other surfactants or conditioning agents for a balanced formula that’s both cleansing and moisturizing.

• Liquid Foaming Products (e.g., Bath Gels, Foaming Cleansers): In liquid foaming products, use 1% to 4% of SLSa to increase foaming and enhance the product’s viscosity. For foaming bath gels or foaming cleansers, you can use 3% to 8% for optimal foam creation while maintaining a sulfate-free formula that is gentle on the skin.

• Powdered Foaming Products: For powdered bath salts, foaming bath powders, and similar formulations, use SLSa at 15% to 25% to create a satisfying foaming effect while ensuring the product is mild and non-irritating.

Formulation Tips 

• Blend with Other Surfactants: For a balanced formula, combine SLSa with other gentle surfactants like coco-glucoside or decyl glucoside. This helps enhance foaming while maintaining skin softness, especially in shampoo bars or facial cleansers.

• Use in Hot or Cold Processes: SLSa is versatile and can be incorporated in both hot and cold processes. When adding SLSa to heated phases, ensure the powder is fully dissolved to prevent clumping.

• Safety Precaution: When handling SLSa in its powder form, always wear a mask and gloves to avoid inhalation, as fine particles can irritate the respiratory system.

• Adjust Viscosity in Liquid Products: For liquid products like bath gels or foaming cleansers, SLSa not only boosts foam but also increases viscosity, providing a thicker and more luxurious feel to the product. Allow the formulation to sit for 24 hours after adding SLSa for the product to reach its final viscosity.

   

Storage Guidelines

• Storage: Store in a cool, dark, and dry place to ensure that SLSa remains effective. The powder can react with moisture, so it’s important to keep it in a tightly sealed container.
• Shelf Life: 2 years from the date of manufacture if stored properly.

Safety Guidelines

• Always wear a mask when working with SLSa powder to avoid inhaling fine particles, as inhalation can irritate the respiratory system. Gloves and protective eyewear are also recommended. This product is intended for external use only. Avoid direct contact with eyes, and do not ingest. If pregnant or under medical care, consult a healthcare provider before using products containing SLSa. Ensure proper ventilation in the workspace to minimize airborne particles.
