Platform 03 · Powder · Double encapsulation
Protects sensitive and volatile active ingredients until the moment of use.
A fine, free-flowing powder made by double encapsulation: SalSphere® units are re-encapsulated inside a larger, moisture-sensitive microsphere. It protects ingredients such as retinol, fragrance and menthol in the formula, extends shelf life, and releases them on contact with moisture.
The problem
Retinol degrades, fragrance and menthol evaporate, and reactive ingredients interact with the rest of the formula. Performance is lost before the product is ever used.
The core
The active ingredient is first encapsulated in SalSphere® microspheres with a solid lipid core.
The second layer
The SalSphere® units are re-encapsulated within a larger, moisture-sensitive microsphere. This double encapsulation is what gives MultiSal® its protection and shelf life. The outer layer can also carry a second ingredient.
The powder
The result is a fine, free-flowing powder. Tight encapsulation keeps the active ingredient in and keeps diffusion minimal, in emulsions and in anhydrous formats such as oils, sticks, powders and soap bars. It withstands hot processing up to 130 °C.
The release
Moisture from water, sweat or wet lips opens the outer layer and releases the active ingredient. The outer layer’s composition sets the pace, from a fast burst to a slower or delayed release, and two ingredients can be released one after the other.
The format
Spherical microspheres that are soft on the skin and easy to work into creams, lotions, serums, masks, sticks and powders.
Why MultiSal®
MultiSal® keeps sensitive and volatile active ingredients intact through processing and on the shelf. It can also combine ingredients, sequence their release, and bring water-soluble ingredients into anhydrous formats.
Shields retinol, fragrance, menthol and other unstable compounds from degradation and evaporation.
Double encapsulation keeps active ingredients intact until the product is used.
Active ingredients are retained through molding, extruding and baking, then released when wet.
A fresh burst on sweat in deodorants and foot care, or on wet lips in balms and lipsticks.
Brings water-soluble ingredients into oils, sticks, body powders and soap bars.
Optionally carries two ingredients and releases them one after the other.

Encapsulating SalSphere® units inside a second microsphere adds a protective layer around sensitive and volatile active ingredients, which improves stability and shelf life.
Moisture. Release intensity depends on water activity and on the outer layer’s composition. Diffusion is minimal and noticeable only with very volatile ingredients at high loading.
Yes. An outer layer made with water-soluble ingredients releases fast, more complex polymers release more slowly, and a less water-soluble blend gives a delayed release.
Yes. MultiSal® is compatible with traditional lipstick and balm bases and releases when lips are wet. It also lets you load a balm with oils without softening it.
MultiSal® protects ingredients up to 130 °C, so active ingredients are retained through molding, extruding and baking.
Retinol, fragrance, menthol or another sensitive ingredient: we design the core, the outer layer and the release around your active ingredient and your format.
