Elixir is a mid-to-high-end Paris-based cosmetic and pharmaceutical enterprise, whose products are sold in thousands of medical beauty clinics and premium pharmacies across France. Its annual allantoin procurement volume totals 8.6 tons, divided into two customized grades: micro-powder high-purity pharmaceutical grade and low-aldehyde infant & maternal special grade. The client set rigid customized requirements as follows:
1. Purity Standard: HPLC content ≥99.7%, while conventional domestic allantoin complying with national standard only reaches 98.5%~99.2%, failing to meet internal control criteria.
2. Impurity Control: Free glyoxylic acid and amine sensitizing impurities ≤3ppm; heavy metals Pb and As <1ppm. By-products generated by conventional processes exceed the limit and cannot be used in infant formulas.
3. Customized Powder Physical Properties: One grade requires 800-mesh ultrafine powder (for low-temperature dissolution in essence without precipitation), and the other 30-mesh coarse crystals (slow-release substrate for repair creams). Domestic manufacturers only produce standard 200-mesh powder without dedicated screening production lines.
4. Formula Compatibility: The product adopts a weak acid formula with pH 3.2~4.5. Allantoin shall not precipitate and retain over 93% of its active ingredients after 6-month storage in acidic systems, while commercially available synthetic allantoin tends to hydrolyze and lose activity in weak acid environments.
The client previously contacted 3 domestic allantoin manufacturers independently, but all factories only mass-produced standard national standard spot goods and refused to invest in production line transformation and R&D for small-batch customization. Small customized orders bear high R&D costs and low production priority, resulting in outright rejection by multiple manufacturers. If the client continues purchasing European imported raw materials, procurement costs will surge by 42%, bringing heavy pressure on new product pricing. Hence, the client entrusted HiSiaddi to fully manage customized development.
HiSiaddi shortlisted two leading allantoin manufacturers with refined crystal modification capabilities, eliminating mass-production general factories. We collaborated with the client’s R&D department to break down customized parameters and finalized a process combining gradient low-temperature crystallization, multi-stage activated carbon decolorization, and segmented vacuum drying modification. This fundamentally curbs by-product formation and addresses the issue of excessive aldehyde impurities.
· Low-impurity grade for infants & mothers: Optimize raw material inputs by adopting food-grade high-purity glyoxylic acid instead of industrial raw materials; fully enclosed synthesis minimizes free ammonia generation.
· Ultrafine powder grade for essence: Add jet milling and classified screening procedures in the finishing stage, set up independent clean dedicated production lines for small-batch customization, and avoid cross-contamination by separating production from standard bulk materials.
1. First Round Lab Test (500g samples): HiSiaddi coordinated 3 rounds of process adjustments at manufacturers. Each batch came with full SGS test reports, HPLC spectra, and microbial test certificates, which were delivered to the client’s R&D laboratory in France.
2. Pilot Scale-Up (25kg): Resolve the caking issue of ultrafine powder prone to moisture absorption by optimizing drying parameters, limiting loss on drying ≤0.12% to meet storage stability requirements for essence formulas.
3. Terminal Formula Testing: The client incorporated the two customized allantoin grades into repair essence and infant cream respectively. No delamination, precipitation or redness & sensitization issues occurred after 6-month storage under normal temperature and 40℃ accelerated conditions, and all samples passed third-party French safety patch tests.
To meet EU access requirements, 20kg food-grade fiber drums lined with aluminum foil vacuum inner bags were adopted (different from standard PE-lined domestic packaging). HiSiaddi coordinated manufacturers to switch customized packaging materials and established complete production records covering raw material incoming inspection, synthesis & refining, crushing & screening, and finished product delivery for each batch. Each drum was attached with an independent batch COA with full EP Pharmacopoeia test items to satisfy EU import traceability audits.
Restricted by limited capacity of customized production lines, the full 8.6-ton order could not be produced in one batch. HiSiaddi split the order: 4.1 tons of ultrafine powder grade and 4.5 tons of coarse crystal grade, scheduled for monthly production across 5 batches and shipped from Shanghai Port to Le Havre Port via customs clearance.
1. For French premium client Elixir: The comprehensive procurement cost of customized raw materials dropped by 33.7% compared with original German CLR products. The new infant repair cream was successfully launched and ranked among top products in France’s offline infant repair segment within half a year. A 12-ton annual long-term contract was renewed the following year, with additional customized demand for microcapsule coated modified allantoin.
2. For domestic customized manufacturers: Supported by this benchmark European high-end order, manufacturers completed technical upgrading of refined customized production lines, escaped price competition in low-end industrial allantoin, and achieved a 29% export premium for customized grades. Supply chains for multiple Spanish and Italian cosmetic brands were subsequently onboarded.
3. For foreign trade service provider HiSiaddi: We standardized graded customized allantoin services covering full procedures: parameter decomposition → process customization → sample iteration → packaging customization → batched production → export documentation. Subsequent customization entrustments were received from multiple medical beauty raw material brands in Northern Europe and North America.
1. Industry Pain Points: Most domestic allantoin manufacturers focus on mass production of standard national standard spot goods with fixed production lines and low willingness for technical transformation. They generally reject orders involving refined customization of physical & chemical indicators, impurities and particle sizes demanded by overseas mid-to-high-end clients. Raw material parameters required by overseas premium cosmetic brands exceed domestic standards, making localized production difficult without localized supply chain resources.
2. Procurement Logic of Mid-to-High-End Clients: Formula compatibility and product safety are prioritized; clients are willing to pay for customized quality rather than choosing low-cost inferior industrial raw materials.
3. Core Value of HiSiaddi: Leverage supply chain resources to match R&D-oriented manufacturers, coordinate process R&D, sample iteration and production line adjustments as an intermediary, break down barriers between client customized demands and factory mass production transformation, and realize delivery of non-standard customized products.
