Fragrance Fixative for Shampoo with Sodium C14-16 Olefin Sulfonate

Question

Hello. I would like to inquire about fragrance fixatives for a shampoo formulation.

Primary Surfactant: Sodium C14-16 Olefin Sulfonate

Answer 1

For a shampoo formula using Sodium C14-16 Olefin Sulfonate as the primary surfactant, enhancing fragrance longevity (fixation) can be achieved using specific additives designed to help the scent adhere to the hair even after rinsing.

Recommended Fragrance Fixatives

Flora Fix™ (long lasting fragrance):
- This is a specialized fixative designed to extend the "dry-down" period of fragrances. It helps distribute the scent more evenly and makes it last longer on the hair.
- Usage: Typically used at 0.1% - 1.0% in hair care products.
Flora Solve™ Clear (Fragrance Solubilizer):
- While primarily a solubilizer, ensuring the fragrance is perfectly incorporated into the surfactant system is the first step to stability. It helps create a clear and stable micellar structure for the fragrance within the shampoo.
- Usage: Mix with fragrance at a ratio of 2-5 parts Flora Solve™ Clear to 1 part fragrance before adding to the main surfactant base.

Formulation Tips for Sodium C14-16 Olefin Sulfonate

Compatibility: Sodium C14-16 Olefin Sulfonate is a strong anionic surfactant. The fixatives mentioned above are compatible with this system.
Order of Addition: It is generally recommended to mix the fragrance with the fixative (and solubilizer if needed) first, then slowly incorporate this mixture into the surfactant base to ensure maximum stability and scent retention.
Alternative Base: If you are looking for a complete system, SweetWash™ Hair is a shampoo base specifically engineered with a built-in fixative to solve the common problem of fragrance washing away in rinse-off products.
