|What is it?||Sodium (C14-16) olefin sulfonate is a mild solid anionic surfactant made from coconut oil.|
|INCI||Sodium (C14-16) olefin sulfonate|
|Appearance||Fine white powder|
|Usage rate||The CIR Expert Panel has determined sodium (C14-16) olefin sulfonate to be safe for use in rinse-off products (no upper limit mentioned) and safe at up to 2% in leave-on products.|
|Texture||Dry, fine powder|
|Active Surfactant Matter||88%|
|pH||8–10 (5% in water)|
|Why do we use it in formulations?||Sodium (C14-16) olefin sulfonate can function as a primary or complimentary cleansing surfactant in all kinds of formulations.|
|Do you need it?||No; I would chose Sodium Cocoyl Isethionate (SCI) and Sodium Coco Sulfate (SCS) first. Sodium (C14-16) olefin sulfonate is a good alternative to SCS if you are looking for a sulfate-free alternative.|
|Strengths||Biodegradable anionic surfactant with excellent flash foam that performs well over a wide pH range.|
|Weaknesses||It seems to be harder to find than many other surfactants.|
|Alternatives & Substitutions||You’ll need a solid anionic surfactant; SLSa would be my first choice.|
|How to Work with It||Wear a dust mask! Inhaling solid surfactants is incredibly unpleasant.
Include in the water or surfactant phase of products. Can be hot or cold processed, as needed.
|Storage & Shelf Life||Stored somewhere cool, dark, and dry, sodium (C14-16) olefin sulfonate should last two to three years.|
|Tips, Tricks, and Quirks||Sodium (C14-16) olefin sulfonate is especially floaty—make sure you wear your dust mask! It is fine enough that it can be incorporated into solid detergent products (like shampoo bars) without heating.|
|Recommended starter amount||250g (0.5lb)|
|Where to Buy it||Buy it from an online DIY ingredient supplier.|
