In the wave of pursuing efficiency and stability in the cosmetics industry, freeze-dried powder has become the focus of many brands due to its excellent preservation ability for active ingredients. The quality of freeze-dried powder is closely linked to every link of factory processing from the source. From raw material selection to aseptic packaging, careful control at each step is an important guarantee for product efficacy and safety.
Freeze-Dried Powder Processing: A Test of "Precision" and "Cleanliness"
The production of freeze-dried powder starts with the selection and processing of raw materials, which is the cornerstone of quality construction. High-quality raw materials need to be processed in a low-temperature environment to avoid the loss of active ingredients at room temperature. Taking common active peptide raw materials as an example, the whole-process low-temperature cold chain guarantee from harvesting or extraction to transportation and storage can maximize the retention of their biological activity, laying a good foundation for subsequent processing.
Freeze-drying, as the core link of processing, is a double test for technology and equipment. In this process, the raw materials are frozen to an extremely low temperature, and then the moisture is directly sublimated from solid to gas in a vacuum environment. This physical change process requires precise control of parameters such as temperature, humidity and vacuum degree. Different components of freeze-dried powder have different requirements for these parameters. For example, the freeze-drying temperature of some probiotic freeze-dried powders needs to be controlled between -40℃ and -60℃, and the freeze-drying time is maintained between 10 and 24 hours according to the characteristics of raw materials. Precise parameter control can effectively avoid the damage to the structure and activity of heat-sensitive substances caused by traditional thermal drying, allowing active ingredients to be completely retained.
The crushing and sieving link after freeze-drying is related to the user experience of the product. The use of advanced crushing equipment and sieving technology can ensure the uniform particle size of freeze-dried powder. Uniform particle size not only improves the fineness of the product appearance, but also affects its solubility, allowing consumers to enjoy a smoother skin feel when using it.
Aseptic packaging is the last line of defense to protect the quality of freeze-dried powder. The cleanliness of the production area is crucial. High-end freeze-dried powder production lines usually adopt 100,000-level clean areas and local 100-level filling areas to avoid secondary pollution of products during packaging. At the same time, strict testing of the appearance and microbial indicators of the packaged products can further ensure the stability of product quality.
Dongguan Keyan: Interpreting Professional Processing Strength with Standardized Production
In the field of freeze-dried powder processing, Dongguan Keyan Cosmetics Co., Ltd. has become a noteworthy partner with its years of industry accumulation and strict production standards. The company has completed GMPC and ISO22716 certifications since December 2013. These two certifications are important standards in the cosmetics production field, indicating that Keyan has reached an internationally recognized level in production management and quality control.
In the production process, Keyan follows the key points of freeze-dried powder processing. Starting from the strict selection of raw materials, each batch of raw materials undergoes multiple tests to ensure that its purity and activity meet the production requirements. In the freeze-drying link, the company is equipped with advanced freeze-drying equipment, which can accurately adjust various parameters according to the characteristics of different products to ensure the retention rate of active ingredients. The crushing and sieving link adopts automated equipment to realize uniform and controllable particle size and improve the product use experience.
The aseptic production environment is another major advantage of Keyan. The company's production area is strictly built in accordance with the clean area standards. The 100,000-level clean area provides a clean foundation for the overall production, and the local 100-level filling area further ensures the purity of the product during the filling process, effectively avoiding secondary pollution. At the same time, a complete quality inspection system runs through the entire production process. From raw material entry to finished product delivery, multiple inspection procedures check at various levels to provide a strong guarantee for product quality.
With its persistent pursuit of quality and standardized production management, Dongguan Keyan's business has covered the world, providing stable and reliable freeze-dried powder processing services for many brands. In today's continuous development of the cosmetics industry, Keyan empowers the quality of freeze-dried powder products with its professional processing strength and has become a trustworthy choice in brand cooperation.
