A kind of mascara and preparation method thereof

Abstract

The invention provides an eyelash mascara, a preparation method thereof and an eyelash mascara product. The eyelash mascara contains styrene / acrylic acid / methacrylic acid ammonium salt copolymer, di-polyethylene glycol / polypropylene glycol-14 / 14 dimethiconol. Cream of the eyelash mascara of the invention can be uniformly smeared, and has good waterproof effect and lasting cosmetic performance.

Description

technical field [0001] The invention relates to cosmetic products, in particular to mascara and a preparation method thereof. Background technique [0002] Traditional mascara uses Tween or Span as an emulsifier, polyacrylate as a film-forming agent to increase its waterproof performance, and plant-derived carnauba wax to provide its shaping and curling effect. [0003] However, while traditional mascara provides thick curls, it is somewhat lacking in waterproof effect. After a period of time, there will be problems of moistening makeup and poor long-lasting effect. The specific manifestations are as follows: [0004] The makeup effect is not good. The traditional formula has a high content of vegetable wax, generally mainly carnauba wax and candelilla wax, with relatively high melting points, respectively 82°C-86°C and 68°C-73°C, and the paste is relatively thick , and the wax in the formula is not very uniform when the paste is applied, or there is a problem of accumulati...

AI Technical Summary

Problems solved by technology

[0003] However, while traditional mascara provides thick curls, it is somewhat lacking in waterproof effect. After a period of time, there will be problems of moistening makeup and poor long-lasting effect. The specific manifestations are as follows:

[0004] The makeup effect is not good. The traditional formula has a high content of vegetable wax, generally mainly carnauba wax and candelilla wax, with relatively high melting points, respectively 82°C-86°C and 68°C-73°C, and the paste is relatively thick , and the wax in the formula is not very uniform when the paste is applied, or there is a problem of accumulating into particles locally

[0005] The waterproof effect of the traditional formula is not good, because the system of the traditional mascara is an oil-in-water system with Tween or Span as an emulsifier, and the outside is a water phase. The waterproof effect directly depends on the waterproof effect of the film-forming agent, while the traditional film-forming All agents have hydrophilic groups, so the waterproof effect of their products can be imagined. Basically, they are easily wetted by water (external rain) or warm water (tears), which is what people often call makeup;

[0006] The long-lasting effect of traditional mascara is not good, because traditional mascara is shaped by vegetable wax. However, carnauba wax, a vegetable wax, is not flexible. Peel off, the lasting effect is not good;

[0007] Easy to dry material, traditional mascara is filled into the tube, because it is an oil-in-water system, the outside is a water phase, the water is easy to evaporate, and finally the paste thickens and becomes dry material. Although the sealing performance of the tube body can improve this problem to a certain extent, But higher requirements for accessories lead to higher cost and great risk

[0010] The mascara of the water-in-oil emulsification system generally uses Span 80 or Span 85 as the emulsifier, which is generally stable, but if the temperature difference between the inside and the outside changes for a long time, it is easy to break the emulsion, because In the water-in-oil type, the inner phase is the water phase. When the temperature is low, the water will turn into a solid state and the volume will increase, while the outer phase and the oil phase cannot provide enough carrying force to bear the increased volume. water phase, thus causing demulsification and oil-water separation

[0011] 2. Film-forming problem

[0012] Traditional water-in-oil mascara generally uses the effect of wax in the outer phase to form a film, but its toughness is not good, and the wax film will be broken when the eyelashes are bent, resulting in film-forming failure
