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.
