All of our stabilizers have been developed specially for candles. They protect the finished candles and all of their basic components – dyes, fragrances and waxes – from light, heat and chemical reactions, during and after production.
The difference between the various stabilizers has to do with their area of application and their composition.
In addition, we made individual blends for special applications or specifically for dyes, fragrances or waxes, depending on our customers’ needs.

Types of stabilizer
UV-Absorber
Light is composed of waves of different lengths. The energy stored therein can weaken and destroy the raw materials of the candle. UV absorbers are used to protect candles from the light energy found in retailers’ lights and from UV light. These chemicals collect the high-energy UV rays and release this energy as warmth. This prevents the candle from yellowing and fading.
Antioxidants
Candles are generally manufactured with liquid wax that is usually heated during transport, storage and when being processed into candles. Fully refined waxes are extremely heat resistant. Dyes, fragrances and semi-refined waxes are less thermally stable and can be damaged by heat during transport and production.
Antioxidants are used to decelerate the oxidation of dyes, fragrances and waxes. That is why most of our stabilizer blends contain antioxidants.
HALS (Hindered Amine Light Stabilizers)
In the first step, the HALS is activated by the effect of a radical or a hydroperoxide, making it into a radical
The radical produced in this way is then capable of trapping and destroying other radicals in the matrix, thereby creating a chemically stable molecule. The HALS is not used up, but is continuously regenerated.
