Solid depilatory wax and preparation method

Abstract

The invention relates to solid depilatory wax and a preparation method thereof. The solid depilatory wax is prepared from raw materials including the following ingredients in parts by weight: 5-15 parts of a film-forming agent, 60-80 parts of a tackifier, 10-20 parts of wax, 1-10 parts of a functional agent and 0.5-5 parts of a filler. The functional agent includes hydrogenised coeonut oil and hydrogenated styrene-butadiene block copolymer, and the film-forming agent includes ethylene-vinyl acetate copolymer and ethylene-vinyl acetate-vinyl alcohol terpolymer. The melting point of the solid depilatory wax is low, an excellent depilatory effect is exerted under a low melting point condition, and a depilatory effect on fine hair (such as lip fine hair) is great.

Description

technical field [0001] The invention relates to a depilatory wax, in particular to a solid depilatory wax and a preparation method thereof. Background technique [0002] Due to the needs of human beauty, the human body needs to remove excess hair in some parts of the body. Physical hair removal is a more commonly used hair removal method, which can be divided into mechanical hair removal and wax hair removal. [0003] Among them, the depilatory wax used in the wax-type hair removal is basically cold wax in the current technology, and its main component is sugar raw material, and its appearance is paste. There are also reports of hot wax, but the main components are rosin resin, paraffin, grease (mineral oil or vegetable oil), and the appearance is a paste, and the paste depilatory wax must use depilatory paper to assist depilation, that is: apply the depilatory wax to On the part of the skin with hair, then cover the depilatory paper on the depilatory wax on the skin, then...

AI Technical Summary

Problems solved by technology

The disadvantages of this type of depilatory wax are: first, there must be residual wax, and the residual wax must be processed after depilation; second, the consumption of depilatory paper is relatively large, which increases the cost and is not conducive to environmental protection

In addition, the existing depilatory waxes, no matter cold wax or hot wax, all have the disadvantage that the removal of fine hairs (such as the fine hairs of the lips) is not ideal.

[0004] Chinese patent CN105232359A discloses a solid depilatory wax for the human body, which discloses a solid depilatory wax that does not need to use depilatory paper, and has a good removal effect on hairs that are difficult to treat, such as armpits and bikini parts, but does not provide specific information. The hair removal effect test, especially for the removal effect of fine hair

In practical application, the removal of fine hair is still not ideal

At the same time, the melting point is high (54-58°C), the user is inconvenient to operate, and the comfort is poor when using it.

[0005] Chinese patents CN108379120A and CN1868446A both disclose depilatory waxes with a melting point of 45°C to 50°C and can be used at lower temperatures, but they do not illustrate or provide specific hair removal tests, especially for fine hair removal.

Hot wax relies on melting and solidification to absorb hair, and its depilatory effect is easily affected by low temperature.

[0006] In summary, it is difficult for the existing solid depilatory waxes to have both a lower temperature of use and a better depilatory effect, especially for the removal of fine hairs, such as the fine hairs on the face and lips. In addition, in view of the The sensitivity of the skin also requires that the solid depilatory wax products have low irritation and will not cause skin sensitivity
