Silk Fibroin Powder
What is Silk Powder (Silk Fibroin Powder)?
TIZAN Silk Fibroin Powder is a kind of macromolecular silk fibroin in powder form, which is made from the silk fibroin degummed under high pressure, requires special craft processing and smash through physical methods. Its molecular weight of is about 250000. It is tasteless, odorless, slightly soluble in water and insoluble in alcohol ether.
The fibroin protein powder consists of layers of antiparallel beta sheets. Its primary structure mainly consists of the recurrent amino acid sequence (Gly-Ser-Gly-Ala-Gly-Ala)n. The high glycine (and, to a lesser extent, alanine) content allows for tight packing of the sheets, which contributes to silk’s rigid structure and tensile strength. A combination of stiffness and toughness make it a material with applications in several areas, including biomedicine and textile manufacture.
Fibroin powder is known to arrange itself in three structures, called silk I, II, and III. Silk I is the natural form of fibroin, as emitted from the Bombyx mori silk glands. Silk II refers to the arrangement of fibroin molecules in spun silk, which has greater strength and is often used in various commercial applications. Silk III is a newly discovered structure of fibroin. Silk III is formed principally in solutions of fibroin at an interface (i.e. air-water interface, water-oil interface, etc.).
Natural Silk Culture and History
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.
Natural Silk is the Oldest Pride of China
The earliest example of silk fabric has been found in a neolithic site in Henan, and is dating back 8,500 years. Silk fabric from 3630 BC was used as wrapping the body of a child from a Yangshao culture site in Qingtaicun at Xingyang, Henan.
Legend gives credit for developing silk to a Chinese empress, Leizu (Hsi-Ling-Shih, Lei-Tzu). Silks were originally reserved for the Emperors of China for their own use and gifts to others, but spread gradually through Chinese culture and trade both geographically and socially, and then to many regions of Asia. Because of its texture and lustre, silk rapidly became a popular luxury fabric in the many areas accessible to Chinese merchants. Silk was in great demand, and became a staple of pre-industrial international trade. In July 2007, archaeologists discovered intricately woven and dyed silk textiles in a tomb in Jiangxi province, dated to the Eastern Zhou Dynasty roughly 2,500 years ago. Although historians have suspected a long history of a formative textile industry in ancient China, this find of silk textiles employing “complicated techniques” of weaving and dyeing provides direct evidence for silks dating before the Mawangdui-discovery and other silks dating to the Han Dynasty (202 BC-220 AD).
UNESCO designated the Silk Road as a World Heritage Site, and with the development of trade on the Silk Road, most people know the natural silk come from China, fostered and enhanced in Europe and America. It is even regarded as valuable treasure by Japanese in modern times.
Silk as fiber nearest to human skin in the world
Silkworm is a kind of insect belonging to the order Lepidoptera. After peeling off their skin four times, the larva of silkworm would eject silk from mouth and fix it on the ground before put up the false work, which was used as the framework of cocoons, and the project of making cocoons need two to three days. Each mature silkworm has a pair of silk gland which consists of more than 900 gland cells.
At first, the silk protein which was secreted by the silk gland was liquid, and then hardens to silk fiber as soon as it exposes to air from the silk tube.
The silk fiber consist of inside and outside organizations–fibroin (about 75%）and sericin ( about 25%).
The fibroin itself still possesses 35% interval from the volume and the sericin outside also has the Amino Acids that is a hydrophil lateral chain, which make silk has a great function of absorption of moisture and still keep its comfort and coolness in spite of torridness.
Silk fiber can bear 35-44Kg/cm² pulling force in a unit of cross-sectional area and it can still restitute after elongating the 1/7 length of itself, which has excellent flexibility and is light, soft and fluffy.
Silk Powder Silk Fibroin Powder Benefits
Skin care effect
- It has the functions of natural moisturizing and skin nourishing
- Possessing the action of inhibiting melanin production,
- Promoting the regeneration of skin tissue, guard against chapping and chemical damage
- Inhibiting the skin cancer
- Silk protein also possesses the function of antioxidant
Hair-caring, hair-nourishing and hairdressing effect.
Silk protein’s hair-caring function depends on the absorbency, absorptivity, film-forming ability and moisturizing type it received by hair. Compared with other protolysates (collagen, bone collagen, glutin and so on), the biggest feature of fibroin is that it is easy to be absorbed by the hair.
The Nutritional Function of Fibroin Food
Silk protein contains 18 types of amino acid, over 90 percent of which can be absorbed by human body. Its percentage of amino acids which are necessary to human body reaches more than 17 percent, higher than normal food. Therefore, it is a very good way of amino acid supplements to add the fibroin into the food. Japan began the research of turning silk into food as early as 1983. Like silk cake, biscuits, noodles, soba noodles, jelly glues, ice cream, candies, porridge, drink, soy and other kinds which contain components of silk, such as mushroom, tea, capsule, tablets and so on, they have appeared in the market, and are very popular among customers, which become the new generation of healthy food and nourishment in Japan.

Silk Powder Silk Fibroin Powder Main Functions
- Natural Silk Powder Silk Fibroin Powder is an excellent natural moisturizing factor because of the presence of hydrophilic gene in the structure of silk. It can attach a very thin silk powder layer to the surface of skin, which can absorb or release water with the change of the temperature and humidity of skin. This has certain preventive and therapeutic effects on skin protection, preventing and curing various skin diseases caused by moisture and drying.
- The crystalline structure of silk powder can reflect part of ultraviolet ray, and the hollows formed by the spiral structure can again absorb part of ultraviolet ray, so it will make the better sun-screening effect by using the compound of silk powder and sun-screening agent in sunscreen products.
- It has a unique ability of keeping the oil, which makes it more suitable to be used in cosmetics for oily skin.
- The structural features of silk powder can help reduce the reflected light. When being used in cosmetics in which the mica powder is taken as substrate, it can reduce the reflected light and make the skin show vivid and soft colors naturally. Compared with talcum powder and titanium dioxide, it has excellent air permeability, users would feel particularly smooth after applying cosmetics containing silk powder.
