Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, and in particular to an aromatherapy cup wax and a preparation method thereof. Background Art

[0002] As a product that can create different styles of atmosphere, more and more consumers are beginning to use scented candles as daily consumer goods to improve their quality of life. Therefore, the market has put forward higher and higher performance requirements for scented cup candles. In particular, the requirements for its fragrance are constantly increasing. This requires that a higher and higher proportion of fragrances be added to scented cup candles. However, with the increase in the proportion of fragrances in cup candles, cup candle products on the market often have serious problems such as high-temperature oiling and whitening after oiling. If the general solution is used to increase the proportion of high-melting-point wax in the formula, although the oiling problem can be solved, there are contradictory problems such as low-temperature cracking, poor appearance, and poor combustion.

[0003] At present, most of the cup waxes on the market are directly filled after mixing and melting the raw materials (paraffin wax, plant wax, etc.). The cup wax filled in this way is called solid wax; this kind of wax is generally solid and dense, and the consumables increase, so the cost increases. In addition, due to the large cooling shrinkage during the production process, there are often many non-homogeneous structures such as depressions and tunnels inside. This structure will have an adverse effect on the aroma volatilization and thermal stability of the wax column, such as: unstable flames, incomplete aroma volatilization, and oily appearance during the combustion process.

[0004] Patent CN110591826B discloses a foaming cup wax and its production method, and discloses that the specific ingredients of the foaming cup wax are 10-20 parts of soybean wax; 25-30 parts of palm wax; 5-10 parts of soft wax; 30-40 parts of paraffin wax; 1-5 parts of essence; and specifically discloses that the production method is: the raw materials are melted, mixed, and air is introduced, and foamed in a foaming machine by high shear dispersion to obtain the final product. Although the foaming wax obtained by the above patent can solve the problems of uneven bubbles and improve the appearance, the candles obtained by this foaming wax process have a significantly lower density than ordinary candles, and collapse when burning, which will affect the burning stability of the candles. At the same time, with the increase in the proportion of essence, the problem of oil release when the foaming wax obtained by this process is stored at high temperatures will become more and more serious.

[0015] Step 5: Fill the wax liquid into the cup to obtain cup wax.

[0026] The T5 temperature range is 60-75°C.

[0027] The T6 temperature range is 85-100°C.

[0029] Beneficial effects: The present invention discloses an aromatherapy cup wax and a preparation method thereof. The aromatherapy cup wax is composed of the following raw materials in parts by weight: 75-90 parts of plant wax, 0.1-5 parts of stabilizer, 1-15 parts of essence, 0.5-10 parts of emulsifier or 20-90 parts of plant wax, 0.1-5 parts of stabilizer, 1-15 parts of essence, 0.5-10 parts of emulsifier, 5-75 parts of paraffin wax, and 1-10 parts of soft wax; and discloses a preparation method of the aromatherapy cup wax, wherein the plant wax is melted and mixed with the stabilizer or mixed with paraffin wax, soft wax, and stabilizer to obtain a mixed liquid A, an emulsifier is added to the mixed liquid A, and the mixed liquid B is melted by stirring to obtain a mixed liquid B, and the essence is added and stirred to obtain a wax liquid, and the wax liquid is added to a high-speed stirring and high-shear reactor, stirred at a high speed, and vacuum-exhausted, and filled into a cup to obtain the cup wax. In the process of gradually cooling the wax liquid, the present invention controls the temperature of the wax liquid to keep it in a state of slowly forming crystals, disperses the wax that begins to crystallize into microcrystalline particles by high-speed stirring and high shearing, and uses a non-ionic surfactant as an emulsifier to stabilize the formed wax microcrystalline particles. The emulsifier has the functions of dispersing and stabilizing the gel microcrystalline particles and solubilizing the solvent with higher polarity in the essence, so the scented candle prepared by the present invention is not easy to oil out during high-temperature storage, and avoids cracking at low temperatures. Since the candle is filled at a relatively low temperature when it has already crystallized, the wax body does not shrink significantly and internal cavities are not generated after filling, thereby avoiding the problems of combustion collapse and self-extinguishing caused by adding wax when ordinary filled candles are not cooled enough.

[0101] Table 1 Performance test of Examples 1 to 5 and Comparative Examples 6 to 8

[0102]

[0103] As can be seen from Table 1, in the candles of Examples 1 to 5, nonionic surfactants are used as emulsifiers to stabilize the wax crystal microparticles formed, thereby maintaining uniform and tiny microcrystalline particles, so that the surface of the wax body shows a delicate and silky texture and touch, providing users with a better use experience, and the wax that begins to crystallize and precipitate is dispersed into microcrystalline particles by high-speed stirring and high-shearing. At the same time, the emulsifier has the functions of dispersing and stabilizing the gel microcrystalline particles and solubilizing the solvent with higher polarity in the flavor. Compared with Comparative Examples 6 to 8, the candles prepared in Examples 1 to 5 are not easy to oil out in a high temperature environment and do not crack at a low temperature. Since the temperature in the can is lower than that in the normal can, there is no obvious shrinkage and internal voids after canning, thereby avoiding the problems of burning collapse, poor fragrance effect and self-extinguishing of ordinary canned candles.
