What is the difference between SLS and SLSA?


Let me clarify the difference between Sodium Lauryl Sulphate (SLS) and Sodium Lauryl Sulfoacetate (SLSA):


  1. Sodium Lauryl Sulphate (SLS):

SLS is a widely used surfactant and detergent found in many personal care and cleaning products. It is known for its foaming and cleaning properties. SLS is an effective emulsifier and helps products to create lather and remove dirt and oils. However, it can be harsh on the skin and may cause irritation or dryness, particularly for individuals with sensitive skin.


  1. Sodium Lauryl Sulfoacetate (SLSA):

SLSA is a milder and more gentle alternative to SLS. It is derived from coconut and palm oils and is considered a safer and less irritating ingredient compared to SLS. SLSA also functions as a surfactant and foaming agent, but it has larger particle sizes, which reduces its penetration into the skin and makes it less likely to cause irritation. As a result, SLSA is commonly used in personal care products such as shampoos, bath bombs, and bubble baths.


In summary, while both SLS and SLSA are surfactants used in personal care products, SLS is known for its strong cleaning properties but can be harsh on the skin, while SLSA is a milder alternative with reduced skin irritation potential.


How to use SLS and SLSA?


To use Sodium Lauryl Sulphate (SLS) or Sodium Lauryl Sulfoacetate (SLSA), you would typically find them as ingredients in various personal care and cleaning products. Here are some common ways they are used:


  1. SLS:

SLS is commonly found in products such as shampoos, body washes, facial cleansers, toothpaste, and household cleaning agents. When using products containing SLS:



- Shampoo: Wet your hair, apply a small amount of shampoo to your scalp, and massage it gently to create a lather. Rinse thoroughly with water.

- Body Wash/Facial Cleanser: Apply the product to a wet sponge, washcloth, or your hands, and lather it onto your body or face. Rinse off with water.

- Toothpaste: Squeeze a pea-sized amount of toothpaste onto your toothbrush, wet it with water, and brush your teeth as usual. Spit and rinse your mouth afterward.



  1. SLSA:

SLSA is commonly used in bath bombs, bubble baths, and other foaming bath products. Here's how you can use products containing SLSA:

- Bath Bombs: Fill your bathtub with warm water. Drop the bath bomb into the water, and it will fizz and dissolve, releasing the SLSA and other ingredients. Enjoy your bath while the product creates a foaming and aromatic experience.

- Bubble Baths: Add the recommended amount of bubble bath product containing SLSA to warm running water as you fill the bathtub. Agitate the water with your hand or a bath sponge to create bubbles.


Remember, everyone's skin and sensitivity levels may vary. If you have any concerns or experience skin irritation, discontinue use and consult a healthcare professional.


SLS and SLSA Mixing ratio explained


When it comes to mixing ratios, it is important to note that the specific ratios may vary depending on the product, its intended use, and the desired outcome. However, I can provide you with some general examples of mixing ratios for certain applications:


  1. Cleaning Solutions:

   - All-Purpose Cleaner: Mix 1 part SLS or SLSA with 10 parts water (1:10 ratio).

   - Dishwashing Liquid: Mix 1 part SLS or SLSA with 5 parts water (1:5 ratio).

   - Floor Cleaner: Mix 1 part SLS or SLSA with 20 parts water (1:20 ratio).


  1. Personal Care Products:

   - Shampoo: Mix 10% SLS or SLSA with 90% other ingredients. For example, for 100 grams of shampoo, you would use 10 grams of SLS or SLSA and 90 grams of other ingredients.

   - Body Wash: Mix 5% SLS or SLSA with 95% other ingredients. For example, for 100 grams of body wash, you would use 5 grams of SLS or SLSA and 95 grams of other ingredients.

   - Bath Bomb: The mixing ratio for SLSA in bath bombs can vary widely depending on the recipe and desired effect. Typically, it ranges from 15% to 30% of the total dry ingredients. The exact ratio will depend on the specific recipe you are using.


It's important to note that these are general examples, and you should always refer to specific product formulations, recipes, or manufacturer guidelines for the most accurate mixing ratios. Additionally, consider performing a patch test or small-scale trial before producing large quantities to ensure the desired outcome and compatibility with your specific needs.
