Silkworm Chrysalis Protein supplied by Zhenyibio Technology Inc. is an animal‑derived protein powder used in specialised formulations. The product is listed with the INCI name SILKWORM CHRYSALIS EXTRACT and appears as a light yellow to brownish yellow powder. Analytical data show a total nitrogen content of at least 12.8 % and a pH range measured between 5.0 and 7.0. The extract is derived from silkworm chrysalis material processed in China.
The extract contains a complete amino‑acid spectrum with eight essential amino acids present in balanced proportions, a characteristic typical of silkworm protein. Zinc is reported at 19.025 mg per 100 g, which is higher than many plant‑based proteins and supports its use in skin‑care actives. In the broader industry, silkworm chrysalis extracts commonly exhibit nitrogen levels between 10 % and 13 % and maintain low moisture (<5 %) to ensure stability; these ranges are considered typical for premium cosmetic ingredients. The powder is usually milled to a fine particle size below 200 µm and complies with standard microbial limits for cosmetic raw materials.
Buyers such as cosmetics formulators, nutraceutical producers and specialised food manufacturers use this protein for moisturizing, skin‑whitening and anti‑ageing effects as well as nutritional fortification in candy or fortified foods. Zhenyibio offers the material in bulk quantities, but the listing does not disclose minimum order quantity, price or lead time, so interested parties should request a formal quotation. Confirm the desired Incoterm, payment schedule and packaging format directly with the supplier before confirming any purchase.

Before placing an order, importers should verify the supplier’s legal registration in China and request a copy of the business licence to confirm Zhenyibio Technology Inc.’s operating status. Obtain a recent certificate of analysis that details nitrogen, zinc, pH and microbial limits, and ask for any available safety data sheet. Cross‑check the stated address with third‑party databases to ensure the physical location matches the shipping origin.
Discuss logistics early by agreeing on the Incoterm that best suits your supply chain, such as FOB Xi’an or CIF a destination port. Because the listing does not provide lead‑time, ask the supplier for an estimated production and dispatch schedule, and confirm whether freight can be arranged via sea or air. Clarify the payment method, typical being a T/T advance on sample followed by a balance against shipping documents, and request a draft contract reflecting these terms.
To safeguard product quality, arrange an independent third‑party inspection at the manufacturing site or upon arrival, focusing on compliance with the declared nitrogen and zinc levels and the microbial specifications. Request that the supplier include a full COA, safety data sheet and heavy‑metal analysis with each shipment. Maintaining a clear inspection protocol and retaining all documentation will help meet regulatory requirements in your target market.
