|What is it?||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|
|Appearance||You can purchase SCS as a powder or little sticks that look like sprinkles.|
|Active Surfactant Matter||95%|
|pH||7.5–10.5 (1% solution)|
|Why do we use it in recipes?||It offers fantastic, fluffy, super-abundant lather and is a strong cleanser.|
|Do you need it?||It’s very fun (and especially great if you’re making household cleaners), but not essential.|
|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.|
|Alternatives & Substitutions||As a bare minimum you’ll need a different solid anionic surfactant. You’ll also need to watch the active surfactant matter (you will likely need to use a different quantity of the new surfactant to get the same ASM level in the end product as SCS is much more concentrated than most other surfactants). Keep in mind that unless you use Sodium Lauryl Sulfate (SLS) as your alternative surfactant the end product is likely to be lower-lathering and not be as potent of a cleanser.|
|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.
|Storage & Shelf Life||Stored somewhere cool, dark, and dry, SCS should last for two years.|
|Tips, Tricks, and Quirks||Sodium Coco Sulfate (SCS) is made from whole coconut oil, while Sodium Lauryl Sulfate (SLS) is made from lauric acid, an isolated fatty acid that is present in coconut oil. That means SCS will contain some SLS because lauric acid is a component of coconut oil.|
|Recommended starter amount||250g (0.5lb)|
|Where to Buy it||Buy it from an online DIY ingredient supplier or Amazon.|
