Description

Technical Field

[0001] The invention relates to the technical field of depilatory wax, in particular to solid depilatory wax and a preparation method thereof. Background Art

[0002] With the continuous development of society and the improvement of living standards, people pay more and more attention to their own image, especially women in the process of social interaction, who need to remove excess hair on certain parts of the body. At present, the main methods of human hair removal are laser hair removal, physical hair removal and chemical hair removal.

[0003] Laser hair removal requires high technical skills and is not effective for melanin-deficient hair growth cycles. It also poses a safety risk of damaging the skin on darker skin and areas with heavy pigmentation. Chemical hair removal uses chemical reactions to soften hair quickly, allowing it to be easily removed, but it cannot remove hair from the root. Long-term use can cause hair coarsening, pigmentation, skin allergies, and roughness. Physical hair removal includes epilators and waxing. Epilators cut hair on the surface, but when hair regrows, it grows thicker and denser, affecting appearance. Waxing uses the stickiness of wax or polymers to remove hair. It is suitable for large-area hair removal and primarily uses cold or hot wax. Cold waxing is expensive and ineffective. Currently available hot wax has a high melting point and can easily cause burns if not used properly. Hair is also removed along with the wax, causing damage to the skin's stratum corneum and inflammation. Summary of the Invention

The present invention uses the above six ingredients in combination to synergistically improve the analgesic and anti-inflammatory effects of depilatory wax, enhance skin immunity, and repair skin barrier. The lack of any of the above components will lead to a significant decrease in its anti-inflammatory and soothing effects.

[0027] In the present invention, the melting point of the depilatory wax is low through the synergistic combination of natural resin, fatty alcohol, natural wax and tackifier, and no high temperature pain is felt after being applied to the skin; at the same time, the solidification and dripping temperatures of the depilatory wax are similar, so that the wax liquid will not drip after being applied to the skin and hair, and has good skin adhesion, can quickly form a wax film on the surface of the skin and hair, and the wax film has good adhesion to the hair, thereby achieving a good depilation effect and a high depilation rate.

[0028] The present invention does not limit the addition amounts of component A and component B. In a preferred embodiment, the mass ratio of component A to component B is 1-2:2-5. Further preferably, the mass ratio of the peppermint oil, purslane extract, golden chamomile extract, houttuynia cordata extract, and scutellaria baicalensis extract is 1:1:1:1:1-2.

[0108] Hair removal rate test: 48 volunteers aged 18 to 35 were recruited and divided into 8 groups, with 6 volunteers in each group (half male and half female). The volunteers were tested with the solid depilatory wax prepared in Examples 1-4 and Comparative Examples 1-4. The test method was as follows: First, skin with evenly distributed hair on the volunteers' calves was selected. A rectangular area (10 cm × 5 cm) with a length and width of 10 cm and 5 cm, respectively, was marked on the skin surface. The melted solid depilatory wax was then evenly applied to the marked rectangular area. After the depilatory wax film formed, it was removed. The 10 cm × 5 cm skin area was then divided into 100 small squares of equal size. Finally, the residual hair in each small square was observed. If no hair remained in the small square, the hair removal was successful. The number of small squares with successful hair removal was counted and the hair removal rate was calculated by dividing the number of small squares with successful hair removal by the total number of small squares (100). The average value was taken. The test results are shown in Table 1.
