从China供应商批发进口8d Sodium Hyaluronate — FOB条款

Shan Dong Li Young Biotechnology Co., Ltd. supplies an 8D sodium hyaluronate cosmetic raw material as a transparent liquid at 99 percent purity, CAS registry numbers 9067-32-7 and 9004-61-9. The '8D' nomenclature denotes eight distinct molecular-weight fractions, a formulation strategy that positions different hyaluronate chain lengths at varied skin depths to mimic native tissue distribution. The Shandong-origin product is offered under the Liyoung Biotechnology brand name with cosmetics-grade certification. Buyers should note that molecular-weight distribution data, endotoxin limits, and microbial specifications are not provided in the source and must be requested directly.

Sodium hyaluronate, the sodium salt of hyaluronic acid, exhibits moisture-retention capacity proportional to molecular weight: high-MW fractions (1,000-2,000 kDa) form surface films, while ultra-low fractions (under 10 kDa) may penetrate deeper but carry inflammatory risk if impure. An 8D system typically blends very high, high, medium, low and oligo-HA categories to achieve time-release hydration. The 99 percent purity figure likely refers to assay by carbazole or ELISA method relative to total solids, yet this is not specified. Standard cosmetics-grade HA should carry endotoxin levels below 0.05 EU/mg and total aerobic microbial counts under 100 CFU/g per ISO 21149; buyers must confirm whether Li Young tests to these thresholds.

This raw material targets formulators of toners, facial masks, serums and moisturisers in the cosmetic and dermocosmetic industries. Application rates in finished products typically range 0.01-2.0 percent w/w depending on MW fraction and desired viscosity build. The liquid presentation suggests pre-dissolved aqueous solution rather than dry powder, which affects preservative load and cold-chain requirements. No MOQ, lead time or packaging format is listed in the source data. Shan Dong Li Young Biotechnology is located in Sishui County, Jining City, Shandong Province, and holds harbour trust-tier status with no recorded response-rate history.

Shan Dong Li Young Biotechnology Co., Ltd. is headquartered south of Xiquan Yinlu, Shenghe Road, Economic Development Zone, Sishui County, Jining City, Shandong Province, China. The harbour trust-tier designation indicates baseline platform verification without premium audit status. Response-rate and average-response-hour metrics both show zero, which may reflect a newly listed account, seasonal closure, or data-capture gap rather than operational incapacity. Buyers should initiate contact through multiple channels and allow generous time for reply.

The company operates under the Liyoung Biotechnology brand and focuses on cosmetic-grade biotech raw materials. No manufacturing-scale information, GMP certification status, clean-room classification, export license details, or client portfolio appears in the provided profile. The Shandong location places it within China's significant chemical and biotechnology manufacturing corridor, yet proximity to industrial zones does not confer quality assurance. Buyers should request the business license, cosmetic raw material production permit, and any ISO 22716 (GMP for cosmetics) or ISO 9001 certificates before sample procurement.
