Description

Depilatory wax and preparation method thereof

Technical Field

The invention belongs to the technical field of depilatory wax materials, and particularly relates to depilatory wax and a preparation method thereof.

Background

With the continuous development of society and the improvement of living standard, people pay more and more attention to their own image, especially women need to remove the unnecessary hair of some parts of the body in the social process. The main methods for removing human hair include physical depilation, chemical depilation and photoelectric depilation.

Wherein, the physical depilation is realized by external force, so that the hair is pulled out. Mainly including mechanical depilation and wax depilation. Mechanical depilation generally refers to an electric depilator, and the depilation mode has the characteristics of unclean depilation, incomplete depilation, more residues and the like. Whereas wax depilation mainly uses cold wax or hot wax. The cold wax is prepared from saccharide and has a paste shape. The hot wax mainly comprises rosin resin, paraffin and grease. Whether cold wax or hot wax epilation, epilation paper is required as an auxiliary material. It is a practice to apply the depilatory wax to the site with hair, then to cover the depilatory paper on the surface of the depilatory wax on the skin, and then to tear off the depilatory paper quickly. The hairs are removed as the depilatory paper leaves the skin surface.

The Chinese patent application with the application number of 201510747031.8 provides a solid depilatory wax for human bodies, which is prepared from the following raw materials in percentage by mass: 10-70% of tackifier, 1-10% of plasticizer, 0.1-5% of flexibilizer, 0.2-10% of film forming agent, 1-5% of stabilizer, 0.5-5% of perfume, 0.3-3% of pigment and the balance of wax. The preparation method needs to be carried out at the temperature of 180 ℃ or above, and the prepared depilatory wax has the melting point of 54-58 ℃ and the penetration degree of 5-25 (100g, 25 ℃, 1/10 mm). Although a relatively ideal depilating effect is achieved, the temperature of human skin is between 20 and 47 ℃, the skin can generate temperature sense at 35 ℃, the temperature of the human skin is higher than 45 ℃, the human skin can feel heat and have a hot feeling, and when the temperature of the human skin is higher than 47 ℃, the scald pain can be easily generated; beyond 50 ℃, it can scald and form blisters. Therefore, the solid depilatory wax for the human body has good depilatory effect, but the melting point is higher than 54 ℃, so that the depilatory wax is dangerous to scald when being heated and melted and then directly coated on the surface of the human body, and is cooled to below 50 ℃, the coating effect is not good, the tape-casting property is poor, and the depilatory effect can not be achieved, so that the ideal depilatory effect is only the depilatory effect in an ideal state, and other negative effects such as scalding can be brought in practical application.
