MultiSal® Fragrance

PID# MSFR

Encapsulated fragrance technology for skincare, hair care and cosmetic products.

  • Extends fragrance performance and stability
  • Moisture-triggered release for a burst of fragrance upon water activation
  • Powder form for easy handling
  • Fragrance is protected making it suitable for incorporating into hot processes



Introduction

Typical fragrances are liquid, volatile, and require special conditions and equipment to handle. Some fragrances are sensitive to the product base and tend to react and discolor.

MS FR is designed to protect fragrance from premature evaporation, sustain the release, and protect it from the base ingredients. It is designed to transform the liquid into powder to ease handling.

Unique Features

  1. Moisture-Triggered Release: MultiSal® technology is engineered to release a burst of fragrance upon water activation.
  1. Long-Lasting Fragrance:Fragrance is released slowly and continuously over time to extend nFragrance Intensity.
  2. Increased Safety & Ease Of Handling: Suitable for incorporating into hot processes.

 

How The Technology Helps You

MS FR is based on a double-layered encapsulation. The fragrance is encapsulated within hydrophobic, sub-micron spheres that are encased within a larger hydrophilic microsphere. The double encapsulation provides extra protection for the fragrance. Once the outer shell is exposed to moisture and friction, it breaks down and releases the sub-micron spheres containing the fragrance, which then release fragrance via diffusion over a prolonged period of time.

Long-lasting Fragrance Release

Fragrance intensity was evaluated from two deodorant sticks: one containing 1.5% fragrance from MultiSal®, and another with free fragrance. MultiSal® controls the release of the fragrance over the course of 12 hours and maintains a higher intensity over the free.

Evaluation of fragrance intensity over time from a deodorant stick containing 1.5% fragrance from MS FR compared to free fragrance.

Long-lasting Fragrance Release

Fragrance intensity was evaluated on a scale of 0-5 before and after water activation of a dry shampoo containing free fragrance and MS FR at 0.5% fragrance loading. After exposure to moisture, fragrance intensity from the MultiSal® application nearly tripled.

Heat Stability

The structure of MultiSal® is resilient up to 160°C. This qualifies MS FR for use in various hot pour procedures without significant fragrance loss. Thermogravimetric Analysis (TGA) was used to determine at what temperature the MultiSal® system will break down.
