Import Silk Amino Acids — Buy in wholesale FOB from Supplier in China

Zhenyibio Technology Inc. offers a cosmetic‑grade silk amino acids ingredient derived from hydrolysed mulberry silk protein. The product contains an average molecular weight of 90‑100 Da and delivers a total amino‑acid content of 83 %. Additional analytical data list a total nitrogen level of 15 % and a solution pH between 4.5 and 6.5. It is supplied either as a white powder or as a light‑yellow transparent liquid, as indicated in the INCI entry “Silk Amino Acids”. The supplier’s address is No 29 Kejiliulu, Gaoxin District, Xi’an, Shaanxi, China, and it carries a harbour‑level trust tier with no recorded response rate.

In the cosmetics sector hydrolysed silk proteins typically show a purity of at least 95 % and a solubility of roughly 10 % w/w in water at 25 °C, which are considered standard for formulation use. Such ingredients are valued for their ability to form a thin, film that enhances skin moisturisation and hair strength. The molecular weight range of 90‑100 Da is typical for low‑molecular‑weight silk peptides, facilitating deep penetration into the epidermis. Compliance with ISO 22716 Good Manufacturing Practice is a common benchmark for cosmetic raw materials, and many formulators also look for a documented absence of heavy metals and microbial contamination.

Formulators incorporate the amino acids into anti‑age serums, moisturising creams, hair conditioners and scalp treatments to improve elasticity and reduce the appearance of fine lines. Trade negotiations usually involve bulk quantities, with standard packaging of 25 kg drums for powder or 5 L containers for liquid, and incoterms such as FOB or CIF are typical. Buyers should request a Certificate of Analysis, confirm the pH of the supplied batch and agree on payment terms before shipment.

Zhenyibio Technology Inc. is located at No 29 Kejiliulu, Gaoxin District, Xi’an, Shaanxi Province, China.
