Silk originates from silkworm cocoons and is the secretion of silkworms. Its main components are silk fibroin and sericin. It has a usage history of over 5000 years in China. Silk fabric is a textile woven from silk. The skin feel of silk fabric is comfortable, soft, and smooth. Silk belongs to natural protein molecules and has excellent biocompatibility with the human body. When the human skin comes into contact with silk fabric, it will have a unique soft texture. Silk fabric also has good moisture absorption and breathability, which can absorb sweat secreted by the body and keep the skin comfortable.

Silk powder is processed by a special process and then cut by airflow to form a particle size of 5-10 μ M's silk protein powder (silk fibroin). Silk powder maintains the natural luster and structural characteristics of silk, while retaining its skin affinity, smoothness, and breathability. The protein structure characteristics of silk make its skin feel very similar to human skin, and this protein structure gives silk powder a smooth skin feel like its own skin. In the electron microscope photos, it can be clearly observed that the silk powder presents a very ordered porous structure, which endows the silk powder with powerful water retention, moisture absorption, and breathability properties.

Silk powder is odorless and odorless, slightly soluble in water and insoluble in alcohol and ether. It has excellent dispersibility, excellent breathability, and the ability to absorb oil, making it very suitable for use in cosmetics for oily skin. The hydrophilic groups and crystalline structure present in the structure of silk powder give it a natural and excellent ability to regulate humidity. It has a certain preventive and repairing effect on skin care, preventing various skin problems caused by moisture or dryness. In addition, silk powder can absorb and block radiation and ultraviolet rays, making it particularly suitable for sun protection products.
