Cosmetics development process and formulation design


At present, cosmetics have become a kind of daily chemical products widely used by people. It plays an important role in people's daily life. Therefore, the quality requirements for products are getting higher and higher. How to provide consumers with high quality products? This needs to start from the development of the product. The cosmetics development process generally has the following links:
The first is to have a product idea. This idea is generally carried out by market marketing personnel and planning departments directly under the leadership of the company's marketing department or general manager. After extensive market research, understand the most popular products in the domestic and international cosmetics market, and make recommendations to the R&D department. At the same time, the R&D department of the company should fully investigate and understand the current technological developments and information of cosmetics at home and abroad. Scientific and technical personnel must collect all kinds of scientific and technological information, research materials at home and abroad, and finally the senior management, scientific research and marketing planners of the company jointly establish new products to be developed by the company in the near future, and further develop the medium and long-term research and development plans of the enterprise. That is to produce a generation, develop a generation, reserve a generation.


In the cosmetic formula design process, the dosage form problem must first be considered. For example, to develop sunscreen cosmetics, first determine the dosage form, whether it is sunscreen, sunscreen or sunscreen gel. After the dosage form is determined, the matrix is determined (the matrix is the form of the drug, and the cosmetic is composed of its matrix and various additives, and the additive plays its functional role in the matrix). If the sunscreen is required to be water resistant, the oil phase material in the matrix should be selected to be hydrophobic. The main additive in sunscreen products is sunscreen. There are many types of sunscreens. Ultrafine titanium dioxide is now the preferred physical sunscreen for advanced sunscreen cosmetics. In addition, it is necessary to select a suitable chemical sunscreen agent, and to select a broad-spectrum compound sunscreen agent that can absorb both UVB and UVA bands, which requires a screening experiment by a developer.


 After the formulation, matrix and additive parts are all designed, they enter the production process design. Cosmetics are not a product of chemical reactions, so the formulation process is not complicated, but there are many principles and experiences of compounding, such as the principle of emulsification, the principle of solvent polarity compatibility and the principle of chemical inertia (ie, avoiding the raw material components in production and long-term During the storage process, chemical reactions occur under the action of light, heat and oxygen. The order of addition of raw materials and the order of dissolution, the temperature of addition and the stirring speed and time will affect the overall quality of the final product. Therefore, the production process is very important. One link cannot be ignored.


 After being formulated to form a product, the product also needs to undergo quality testing, including physical and chemical testing and sanitation testing. (Special-purpose cosmetics also need to pass safety evaluation or even efficacy testing). After passing the qualification, they are filled and packaged (in production and preparation). One pollution should be avoided during the packaging process, and finally the goods are formed into the market.
