The hair dye can be divided into three categories according to the time color sustains: temporary hair dye, semi-permanent hair dyes, permanent hair dyes. According to the type, the hair dye can be divided into the cream, gel type, hair shampoo, powder, hair mousse, etc. Today there are varieties of commercially hair product available. The permanent hair dyes with oxidation biotin dyes as main component gets the dominant position, especially in Chinese market.
With the continuous development of science and technology, the Japanese chemical industry for the past 10 years also has made great progress. Technical exchange of information is very active. Raw material selection of hair products, a wider range of more channels, domestic and imports are very convenient, so that the quality has improved significantly. Formula design tends to be more scientific, reasonable, and excellent performance under the premise, more focus on human security. Specific to the hair dye used in the main raw material, oxidation dyes, Chinese production of p-phenylenediamine for the past 10 years the quality has reached a high level. From the content. Appearance with the international advanced countries in the production of quality gap. However, the other main component of hair dye required aminophenol between paracetamol and the corresponding derivatives, for example, about dozens of Chinese manufacturers who wish less. And the quality of the existence of a gap. In recent years, large foreign companies optimistic about the hair products market have joined. Many raw materials import channels unimpeded, for Chinese manufacturers to develop new products, more variety, more color to provide a good support, has been greatly developed in recent years, domestic hair products in quality, technology, variety. It has gradually caught up with the level of developed countries' products. Poor quality products have been gradually eliminated, and out of the market from the formulation technology, although there are a lot of information on the mechanism of oxidative dyeing and dye formation, but in fact the factors that affect the hair color process is a lot. For example: the impact of PH value, the complexity of a variety of raw material compound, the intermediate. Therefore, in the formulation process design, experience still plays a very important role. To the preparation of high performance, stability, hair products is not an easy task.
In recent years the rapid development of the cosmetics industry, while promoting further development of the packaging manufacturer. Hair products packaging quality, it has a direct impact on the length of product stability and shelf life. This is particularly prominent. Such as hair dyes commonly used packaging materials: (1) aluminum-plastic composite bag, composite pipe: its thickness, adhesive fastness, opacity, oxygen barrier such indicators. (2) The pros and cons of aluminum tubes: its anti-corrosion coating uniformity, conductivity, tube hardness, thickness, sealing indicators has a direct impact on the quality of the built-in products. In recent years, domestic manufacturers in the development of packaging materials put into larger research strength, its quality has been greatly improved. Such as Shanghai, Guangdong production of packaging aluminum tubes, composite tubes has reached close to the level of imported material.
In 21st century, society will enter into the aging seniors. With the aging of the population, the seniors’ team will gradually grow. Therefore, the hair products market demand is increasing day by day. In addition, the quality of life to further improve the requirements of the United States is more intense, young people's hair color will be as stylish and constantly changing, further illustrates the hair product has a great potential market. Now people advocate natural minoxidil products with the purpose to become more secure. In recent years, France and other countries have successfully developed a natural hair dye with hematoxylin as the raw material. In addition, the hair products which mimic the melanin production process are constantly evolving. Although their research has made significant development, because the process is difficult to control, with low yield and the unstable hair coloring process, it is more difficult for the formation of commodity and it is difficult to penetrate the hair cortex, the. It can be described that the products have a bright future, but the road twists and have many turn points. Source: http:// www.cosprm.com

The situation that coating film’s thickness can be controlled at a predetermined value is called as the film thickness controllability. The state that desired film thickness has several times repetitive reproduction is known as the film thickness repeatability. Because the vacuum sputterin’s discharge current and target current can be controlled separately, so by controlling the target current can control the film thickness. Therefore, the thickness controllability and repeatability of sp... Continue reading...
