Premium raw material offerings backed by ISO-certified manufacturing and full technical support.
n-Dodecanoylsucrose, chemically identified as Sucrose Monolaurate (CAS Registry Numbers 25339-99-5 and 37318-31-3), stands at the forefront of modern carbohydrate-based bio-surfactants. Composed of a hydrophilic sucrose polar head group covalently linked to a hydrophobic 12-carbon aliphatic laurate tail via an ester linkage, n-Dodecanoylsucrose exhibits an exceptional Hydrophilic-Lipophilic Balance (HLB) value of approximately 15. This specific molecular geometry empowers it as an ultra-mild, highly effective non-ionic emulsifier, solubilizer, and stabilizer across cosmetic formulations, pharmaceutical drug delivery matrices, bioprocess membrane extraction, and green industrial applications.
As global regulatory frameworks under EU REACH, US FDA, and China NMPA accelerate the phase-out of ethoxylated surfactants (SLES, PEGs) and harsh sulfates, procurement executives and cosmetic chemists are seeking certified n-Dodecanoylsucrose manufacturers capable of delivering industrial quantities with rigorous monoester purity (≥80% to ≥95%), minimal residual sugar, and low fatty acid impurities. JIMPOCHEM CO., LTD., a leading chemical manufacturer operating a 500-acre smart production complex in Jinan, Shandong, delivers state-of-the-art sucrose ester production leveraging advanced enzymatic synthesis and continuous molecular distillation.
The chemical synthesis of high-purity n-Dodecanoylsucrose requires sophisticated control over regioselectivity. Sucrose possesses eight hydroxyl groups (three primary at C-6, C-1', C-6' and five secondary). Direct chemical esterification with methyl laurate or lauric acid yields a complex mixture of monoesters, diesters, and higher polyesters. Leading manufacturers employ targeted catalytic strategies to maximize monoester yields.
Utilizes immobilized lipases (such as Candida antarctica Lipase B) in non-aqueous green solvents or ionic liquids. Achieves regioselective monoester yields exceeding 92% at C-6 or C-6' positions under mild thermal conditions (40°C - 55°C).
Base-catalyzed reaction of sucrose with vinyl laurate or methyl laurate in polar aprotic solvents (DMSO/DMF) followed by multi-stage solvent extraction and falling-film molecular distillation to strip residual solvents to <1 ppm.
Physical fractioning process separating mono-esters from di- and tri-esters. Essential for high-clarity liquid formulations demanding stable transparent microemulsions across wide thermal spectra.

In modern cosmetic science, n-Dodecanoylsucrose serves as a key active ingredient for clean-label, eco-certified skincare products. Due to its sugar-head structure, it exhibits zero skin-irritation indices in human repeat insult patch tests (HRIPT). Key formulation benefits include:
In pharmaceutical technology, n-Dodecanoylsucrose serves as a non-toxic permeation enhancer for transdermal drug delivery systems (TDDS) and a stabilizer for solid lipid nanoparticles (SLNs) and niosomes:
Approved as a food additive (E473 in Europe), sucrose esters function as effective antimicrobial emulsifiers in beverage stabilization, bakery texture modification, and post-harvest fruit coatings that delay respiration and weight loss. In green agriculture, n-Dodecanoylsucrose functions as a bio-degradable adjuvant for bio-pesticides, reducing spray surface tension while increasing foliar retention.
The global supply chain for sugar-based surfactants has undergone significant restructuring. Escalating raw material costs and stringent environmental regulations in Western nations have driven global buyers toward established Chinese chemical manufacturers capable of delivering vertical integration, regulatory compliance, and price stability.
Founded in 2010 and strategically located within the Chemical Industry Park of Jinan City, Shandong Province, JIMPOCHEM CO., LTD. operates a 500-acre modern production base equipped with fully automated Distributed Control Systems (DCS). With 16 years of continuous R&D and commercial scale-up experience, JIMPOCHEM bridges the gap between raw ingredient synthesis and finished formulation success.
Direct sourcing of non-GMO cane sugar and natural palm-kernel lauric acid ensures stable raw material cost control and continuous production capability even during global supply chain dislocations.
DCS-controlled reactor loops guarantee precise temperature, pressure, and catalyst dosing controls, eliminating batch-to-batch variance and yielding superior monoester ratios.
Every shipment is issued with batch-specific HPLC analysis, GC residual solvent testing, heavy metal ICP-MS records, and micro-organism count reports for full regulatory compliance.
As industrial biotechnology advances, JIMPOCHEM is pioneering next-generation synthetic pathways for sucrose derivatives. The company's 5-year chemical engineering roadmap focuses on three strategic vectors:
Sourcing fine chemical raw materials globally requires complete transparency regarding safety, transport, and international regulatory filings. JIMPOCHEM supports global clients through a dedicated regulatory compliance department:
