Sodium Coco Sulfate (SCS) - Needles
Also known as Coco Sulfate, Sodium Coco Sulfate (SCS) is a solid anionic surfactant of coconut origin. It is not the same thing as Sodium Lauryl Sulfate (SLS) and is generally accepted as a gentler alternative.
|INCI||Sodium Coco Sulfate|
|Active Surfactant Matter||95%|
The CIR has not declared a maximum usage level for Sodium Coco Sulfate (SCS) in rinse-off products, declaring it “safe for use in rinse-off products”. It is limited to 1% in leave-on formulations (source).
As Sodium Coco Sulfate (SCS) is a very effective cleanser, 1%-15% is generally suitable in liquid formulations. Solid cleansers will generally use quite a lot more as Sodium Coco Sulfate (SCS) is 3%-40% part of the solid-ness. As the CIR has not declared a maximum allowable usage level, let the performance of the formulation be your guide.
|Applications||Shampoos, detergent bars, bubble bath, facial cleansers, baby products, Shaving products|
|pH||7.5–10.5 (1% solution)|
|Why do we use it in formulations?||It offers fantastic, fluffy, super-abundant lather and is a strong cleanser.|
|Strengths||Ample, rich lather and strong cleansing/de-greasing.|
|Weaknesses||It is a stronger surfactant and could irritate very sensitive skin. It also has a higher pH and products made with it typically need to be adjusted.|
|How to Work with It||
Wear a dust mask! Inhaling airborne powdered surfactants is unbelievably unpleasant.
You can dissolve it into the heated water phase for liquid concoctions or stir/mash the powder into blends of butters and/or other surfactants to create syndet bars. It can also be added to the powder phase of bath bombs and other bath products.
Note: If the formulation calls for the powdered version you need to pre-grind it (wear your dust mask!), but the little noodles look really good in shampoo bars as-is, and the fine powder is very flexible!
