Sodium Coco Sulfate (SCS) - Needles
Description |
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% |
Appearance | White noodles |
Usage rate |
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. |

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. |
Benefits |

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!
