Cosmetics process and equipment packaging

Cosmetics as a fashion product, its direction of development is increasingly inclined to natural, curative and versatile. Taking science and technology as the guide, adopting new technology and new equipment to rapidly introduce new products is a major trend in the development of the international cosmetics industry in recent years. Cosmetics process, equipment and packaging containers have made considerable progress in recent years. A total of medium-low energy emulsification method is currently a popular international production process.
The low-energy emulsification method is an emulsification effect using a mechanical emulsifying device. The use of emulsification instead of chemical emulsification reduces the irritation of human skin by surfactants. Water-oil-water multiphase emulsification is a good production process. The paste made by this method consists of numerous ultra-thin microcapsules. The wall thickness of this microcapsule is only 0.01 micron. When it is used, it breaks instantaneously after being pressed, and the essence and natural additives contained in the microcapsules immediately flow out to moisturize the skin. This paste has strong penetration of the skin, so it can be quickly absorbed by the skin, and can form a layer of liquid crystal protective film on the skin surface, which is safe and unstimulated to the human body.
Supercritical CO2 extraction technology is currently the most advanced cosmetic active ingredient extraction technology in the world, especially for heat-sensitive substances, so that the active ingredients therein are not lost. Japan has successfully extracted linoleic acid and linolenic acid from safflower seeds using supercritical carbon dioxide extraction technology.
In terms of cosmetic formulations, it has been common for foaming agents to be used as hair setting agents, and now foaming products are available for cleansing cosmetics and foundation cosmetics. This product is shaped like a creamy foam, which feels smooth and moisturizes the skin. Utilizing volatile silicone oil, the United States and Japan have skillfully combined pigments with other raw materials and successfully developed lipstick bases that are not suitable to peel off, making lipstick configuration technology a major step forward.
As many cosmetics add natural additives, physiologically active substances, proteins, etc., higher requirements are placed on the preservation of the product. There are currently two trends in the development and application of cosmetic preservatives. First, foreign countries tend to use composite preservatives, of which the most widely used is the complex of Cermail 115 with propylparaben and paraben. The single preservative is bestowed with Dowic 1200 and BronDpol. In recent years, the use of Germail 115 and Kathon complexes and Girdantin has increased rapidly. Another trend is the widespread use of various synergists, in particular phenoxyethanol, propylene glycol, antioxidants and the like. U.S. International Fragrance Research Institute has developed a preservative fragrance that combines excellent antibacterial properties with excellent aromatic characteristics to achieve excellent antiseptic and aromatic effects. The technology is now industrialized.
With the increase in the content of cosmetic technology, production equipment also tends to be computerized. For example, vacuum homogenizers have evolved from a single homogeneous emulsification to computer program control. When the production process is completed, the entire process conditions are input, and the computer automatically controls. The technological process enables the entire process of weighing, feeding, etc. to be completed automatically and accurately. And can automatically record the entire production process of viscosity, conductivity and temperature changes. Filling equipment also realizes computer control, so that bottle feeding, filling, capping, screwing and cartoning are completed once.
As a fashion consumer product, cosmetics need high-quality packaging materials to increase their value. Glass, plastic, and metal materials are the main cosmetic packaging materials currently used. At present, the development of cosmetic packaging containers in the world is focused on the development of new materials and new processing technologies, and the pursuit of new shapes to highlight the novelty and elegance of the products.
Due to the consideration of product safety, the content of cosmetics tends not to be colored, resulting in a significant increase in the use of colored glass bottles. In the post-processing direction, a variety of color technologies such as gold, silver, pearlescent, and the like can be directly printed out and are very popular in the manufacture of cosmetic containers.
Replacing glass with plastic has become a major reform of cosmetic packaging containers, which makes cosmetics more portable and ensures safety. Because of its glass-like luster, PET resin has been rapidly applied to cosmetic containers in recent years and has largely replaced the original glass bottle. Since the newly developed polyethylene stretch blow molding technology overcomes the disadvantage of the low transparency of polybenzene blown bottles, such packaging containers are used in many cosmetic countries. The appearance of the hybrid injection molding machine can inject two different colors of raw materials into the mold at the same time to obtain a two-color mixed pattern. At present, a molding machine capable of producing 3-4 colors has been developed in the country.
Metal plastic is also one of the main materials for cosmetic packaging containers, and is mostly used for the packaging of lipsticks and powder cakes. It has changed from the earlier brass to aluminum, and fewer and fewer metal containers. The development direction of this product is to produce a combination of metal and plastic containers.
