Kerax KeraSoy Massage Container 4115 is a special soft, low-melting-point Soy Wax blend from the British manufacturer Kerax, which has been developed for the production of massage candles and candles poured into glass and other containers. The wax is characterized by its soft consistency and low melting point, which make it suitable for making massage candles. When melted, it forms a liquid wax blend that, provided the formulation is suitable and deemed safe, can be used in massage products.
KeraSoy Massage 4115 is made from plant-based raw materials; it is vegan, palm oil-free, and biodegradable. The manufacturer confirms that the wax has been dermatologically tested on humans and that no animal-derived ingredients are used in its production, nor are any animal tests conducted.
The wax is suitable for use with fragrance oils and oil-soluble candle dyes and does not require any additional additives when making standard jar candles.

Using Fragrance Oils
KeraSoy Massage 4115 allows you to use up to 10–12% fragrance oil when making standard jar candles. For best results, the manufacturer recommends choosing fragrance oils that are suitable for use with natural waxes.
The compatibility of the fragrance oil affects the quality of the candle’s surface, its burn, and the diffusion of the scent. An excessive amount of fragrance oil or one that is incompatible with the wax can cause the oil to separate, result in an uneven surface, or lead to burning problems.
When making massage candles, only fragrances that are suitable for application to the skin and permitted at the appropriate concentration should be used (see the IFRA documents for each fragrance oil). The 10–12% fragrance concentration permitted for regular candles does not mean that the same amount would be safe in a massage product applied to the skin.
Pouring and Cooling
The recommended pouring temperature is 45–55 °C, but the optimal temperature depends on the size of the Glass Candle Jars, the fragrance oil used, and the dye. To ensure better adhesion to the sides of the glass, Glass Candle Jars can be preheated to 45–50 °C before pouring.
The wax has been formulated so that, for most container candles, a single pour is sufficient. For larger containers, an additional thin layer of wax may be necessary to achieve a smooth surface.
After pouring, allow the candles to cool evenly, avoiding drafts and sudden temperature changes.
Cure time – candle hardening
The manufacturer recommends allowing the finished candles to cure undisturbed for at least 48 hours before the first test burn. This allows the wax to fully stabilize and provides an opportunity to assess the candle’s burn, the formation of the melt pool, and the wick’s suitability. For scented candles, a longer curing time can improve fragrance diffusion, but the optimal time depends on the specific fragrance oil and recipe.
Frosting and Surface Quality
As with other plant-based Soy Waxes, KeraSoy Massage 4115 may exhibit crystallization (or “frosting”), unevenness, or separation from the glass container.
To reduce these phenomena, the following is recommended:
- Keep the melting temperature consistent
- Avoid excessive and prolonged heating of the wax
- Preheat the Glass Candle Jars if necessary
- Cool the candles slowly and evenly
- Avoid sudden temperature changes
- Test the compatibility of the fragrance oil and dye with the wax
- For minor surface defects, adjusting the pouring temperature by 5–10 °C may help.
Important to know
KeraSoy Massage 4115 is a soft pot wax, which means it is not intended for use on its own to make molded or pillar candles.
Regarding massage candles: if the melted wax mixture is intended for application to the skin, the finished product must be treated as a cosmetic product, and you must ensure that the entire formulation complies with applicable cosmetic product requirements, including a safety assessment.
Using dermatologically tested wax does not automatically mean that the final product made from it is safe for the skin.
For best results, always test the specific combination of wax + fragrance oil + color + wick + Glass Candle Jars.
Store the wax in a dry, cool place, protected from sunlight, moisture, and direct heat.
