I. Core Basic Information, Production Processes & Grade Dividing Standards

1.1 Basic Identification & Core Properties

· Full Name: (4S)-2-Methyl-1,4,5,6-tetrahydropyrimidine-4-carboxylic acid; Common Names: Ectoine

· CAS No.: 96702-03-3; EC No.: 431-910-1; Molecular Formula: C₆H₁₀N₂O₂; Molecular Weight: 142.16

· INCI Name: Tetrahydromethylpyrimidine Carboxylic Acid; National Standard: T/CSBM 0061-2025 (Medical Device Grade); International Certifications: USP, EP, REACH, GHS, CosIng

· Source: Biosynthesis via fermentation of halophilic bacteria (the only compliant natural production route); No mature mass chemical synthesis processes; all pure-grade products on the market are extracted via fermentation

· Chiral Critical Standard: Only S-Ectoine delivers moisturizing and skin-repairing activity; R-isomer is an inactive impurity, strictly limited to 0.1% / 0.2% under global regulatory standards

· Physicochemical Properties: White crystalline powder; highly soluble in water; pH of 1% aqueous solution ranges from 6.0 to 8.0; Specific Rotation [α]ᴰ²⁰: +139.0° ~ +145.0°; Melting point: decomposes at 280℃; resistant to light, heat and acid-base conditions; compatible with sodium hyaluronate, ceramides and plant extracts without incompatibility issues

1.2 The Only Mainstream Production Process (Primary Judging Criterion for Sourcing: Huge Differences in Compliance & Impurity Levels)

Standard compliant industry route: Halophilic bacteria fermentation → bacterial milking → cation exchange → two rounds of low-temperature recrystallization

1. Fermentation: Halomonas bacteria synthesize ectoine under hyperosmotic induction; hypoosmotic "milking" releases products intracellularly with minimal residual bacterial protein

2. Purification: Deproteinization → desalination → ion exchange impurity removal → ethanol recrystallization → activated carbon decolorization → vacuum drying

3. Grade Differentiation: Medical/medical device grade requires additional three rounds of chromatography, sterile filtration and endotoxin removal procedures; cosmetic grade only undergoes two rounds of recrystallization; crude industrial materials skip advanced chromatography, leading to high ion impurities and bacterial residues

1.3 Four Mandatory Product Grades (Non-interchangeable & Non-substitutable with Clear Indicator Thresholds)

2. Falsified Purity & Activity Risk: Products only labeled "Ectoine" with concealed fermentation / rough filtration processes, HPLC purity, R-isomer range and conductivity; end-product moisturizing & repair efficacy drastically reduced, failing CosIng/FCC minimum standards leading to port detention and full-container destruction overseas

3. Photo-Oxidation Degradation & Activity Loss Risk: Transparent drums without vacuum nitrogen-filled light-proof lining stored for 3–6 months lead to powder yellowing and browning, over 15% loss of active ectoine; finished serums and masks develop spots, stratification and off-odors triggering mass consumer complaints and compensation claims

4. Cross-Border Compliance Deficiency Risk: Missing FDA GRAS, EU Organic, REACH and special PAH test reports leading to prolonged overseas port detention and unmarketable products; pesticide residues on corn fermentation raw materials violate REACH regulations in multiple countries resulting in full product removal from shelves

5. Raw Material Supply Volatility Risk: Corn starch serves as fermentation carbon source with annual production cycles; seasonal capacity fluctuations, environmental production restrictions and tight supply of recrystallization ethanol resin cause supply shortages and sharp price hikes for organic high-purity ectoine during peak demand seasons

6.2 Standardized Mitigation Measures

1. Rigid Source Process Control: Contracts must explicitly stipulate "fresh corn starch controllable halophilic bacteria fermentation + two rounds of low-temperature salting-out recrystallization deep purification" as mandatory delivery standards; each batch must be accompanied by complete chiral HPLC chromatograms with full refund & compensation clauses for non-compliance

2. Lock Rigid Thresholds for Purity & Chirality: EU export food grade minimum HPLC purity ≥98.5%, high-end pharmaceutical grade ≥99.0%; maximum R-isomer thresholds written into compensation clauses with full batch return for non-compliant test results

3. Mandatory Vacuum Nitrogen-Filled Light-Proof Aluminum Foil Packaging: All standardized high-purity products with 98.0–100.5% purity adopt double-layer light-proof vacuum aluminum foil drums; moisture and cold-water turbidity testing mandatory upon incoming; batches with moisture ＞0.5% / turbidity ＞0.1NTU prioritized for consumption to avoid long-term storage activity loss

4. Full Pre-Shipment Compliance Verification: Complete verification of FDA GRAS, full REACH registration, PAH and ethanol test reports prior to export; organic raw materials require full-year soil & water quality test records; only high-priority testing tool-verified data can adjust standard thresholds

5. Dual-Supplier Diversified Stocking Mechanism: Split orders between two compliant leading manufacturers for organic high-purity and general crude food grades with physical warehouse separation; maintain 1–1.5 months of safety inventory; sign annual long-term contracts to lock purchase prices

6. Pre-Batch Accelerated Stability Verification: Complete 3-month 40℃ accelerated aging test before bulk ordering; only proceed with procurement after confirming no significant purity loss, browning or intensified off-odors

Three core principles for global Ectoine sourcing: Prioritize controllable halophilic bacteria deep fermentation + two rounds of low-temperature salting-out recrystallization deep purification processes; strictly separate four purity tiers: 99.0 USP sterile medical grade with three rounds of chromatography / 98.5 fermented cosmetic export standard grade / 98.0 general industrial grade / ＜98.0 crude waste grade; enforce triple indicator controls of HPLC dry-base purity + chiral R-isomer content + conductivity; ensure full set of international REACH/GHS/CosIng/COA compliance documentation.

Two-recrystallization low R-isomer fermented cosmetic grade ectoine is a mandatory market access standard for EU organic, maternal & infant, medical beauty and high-end oral sectors and cannot be substituted with low-cost crude industrial waste. The 99.0% three-chromatography sterile high-purity grade fits low-dosage ophthalmic / injectable / organic special medical food applications; the 98.5% two-recrystallization fermented grade serves global food & cosmetic export mainstream; the 98.0% single-recrystallization grade is limited to domestic low-end industrial use; crude waste ＜98.0% is strictly prohibited from human export channels with no cross-tier substitution allowed. EU REACH imposes strict controls on R-isomers, organic solvents and ionic impurities; full fermentation + two-recrystallization process traceability reports must be provided for all exports.

1. Organic cross-border maternal & infant care, sterile eye drops, post-procedure medical beauty dressings and high-end oral repair sectors must adopt 99.0–100.5% three-chromatography fermented high-purity ectoine powder with complete USDA/EU Organic, FDA GRAS, E1105, REACH and PAH full-item international compliance COA test documents; prioritize 200 mesh cold-water soluble ultra-fine powder for children’s oral liquids and mucous membrane skincare formulations with strict control over turbidity and microorganisms

2. Domestic mass-market washing & care products, general canned food and Southeast Asian low-cost industrial bulk procurement can select standardized single-recrystallization 98.0% industrial grade ectoine with prominent cost advantages, limited to domestic sales and banned from EU / Japanese export channels

3. Strictly isolate crude industrial raw materials with high R-isomer, ethanol and ionic impurities to prevent diversion into human food, cosmetics and cross-border health supplement sectors; avoid three major hidden losses: false raw material labeling violations, insufficient repair efficacy, turbid/stratified beverages & serums and full-container detention overseas
