Analytical insight into Sucrose Monolaurate: Structural advantages, thermodynamic properties, and high-purity standards.
CAS 25339-99-5, systematically identified as Sucrose Monolaurate (or α-D-Glucopyranoside, β-D-fructofuranosyl, dodecanoate), represents a premier non-ionic, sugar-based ester surfactant. Formed through the esterification of renewable sucrose with lauric acid, CAS 25339-99-5 offers an exceptional combination of biocompatibility, complete biodegradability, zero skin irritation, and potent surface tension reduction.
As global regulatory bodies like the EU REACH and FDA continuously restrict traditional ethoxylated (PEG-based) surfactants due to 1,4-dioxane contamination risks, CAS 25339-99-5 has emerged as a gold-standard substitute for clean-label personal care, pharmaceutical delivery systems, food preservation, and bio-agrochemicals.

Unlike conventional polysorbates (e.g., Polysorbate 20), CAS 25339-99-5 exhibits a high HLB value (~15), making it an extraordinarily potent O/W (oil-in-water) emulsifier. It creates stable nano-emulsions with droplet sizes under 100 nm without requiring high-shear homogenization. Furthermore, JIMPOCHEM’s refined enzymatic catalytic route eliminates residual free sucrose and unreacted fatty acids, yielding a product that retains thermodynamic clarity across broad pH ranges (4.5 to 8.5).
How CAS 25339-99-5 drives formulations in personal care, pharmaceuticals, food systems, and green industrial applications.
CAS 25339-99-5 acts as a mild, non-irritating emulsifier and solubilizer for delicate skin care. It effectively solubilizes lipophilic active ingredients, essential oils, and fragrance compounds into crystal-clear aqueous gels without damaging the natural skin barrier.
In oral liquid formulations, topical gels, and lipid nanoparticles (LNPs), Sucrose Monolaurate enhances the bioavailability of poorly water-soluble APIs (BCS Class II and IV drugs). Its non-toxic metabolic breakdown into sucrose and lauric acid provides safety compliance for parenteral and mucosal applications.
Used as an E-number approved food additive, CAS 25339-99-5 exhibits intrinsic antimicrobial properties against Gram-positive bacteria and yeasts due to the bio-activity of lauric acid esters. It stabilizes dairy emulsions, beverage clouds, and bakery shelf-life enhancers.
As a 100% bio-based wetting agent, Sucrose Monolaurate lowers droplet dynamic surface tension on foliage surfaces, enhancing systemic absorption of bio-pesticides and micro-nutrient fertilizers while leaving zero eco-toxic residue in soil ecosystems.
Because CAS 25339-99-5 generates low-foaming, highly rinsable surfactant matrices, it is increasingly adopted in high-tech semiconductor ultra-pure equipment cleaning and food processing reverse osmosis (RO) membrane foulant removals.
In life science research, CAS 25339-99-5 serves as a non-denaturing surfactant for membrane protein extraction, stabilizing delicate enzyme conformations during chromatographic purification processes.
Why global chemical procurement managers partner with JIMPOCHEM for continuous, cost-optimized, and high-purity supply.
Situated in the Chemical Industry Park of Jinan City, Shandong Province—the core hub of China’s petrochemical and bio-refining infrastructure—JIMPOCHEM enjoys direct access to premium natural fatty acid feedstock and sugar refining plants. This eliminates intermediary transport costs and guarantees baseline cost competitiveness for CAS 25339-99-5.
Traditional chemical esterification produces dark-colored sucrose esters with undesirable byproduct mixtures (di-esters and tri-esters). JIMPOCHEM employs proprietary low-temperature enzymatic catalysis combined with multi-stage thin-film molecular distillation to select monoester fractions up to 85% purity with pristine light color.
Our ISO9001 and ISO14001 certified smart manufacturing plant automates dosing, temperature, and reactor pressure parameters. Every production batch of CAS 25339-99-5 undergoes rigorous HPLC, GC, and ICP-MS testing before packaging. Batch numbers link to stored digital CoA records for total audit visibility.

For smooth customs clearance and regulatory submission, every shipment of CAS 25339-99-5 from JIMPOCHEM is accompanied by standard regulatory documents:
Sucrose Monolaurate is hygroscopic in nature. To prevent moisture absorption and caking during transatlantic transit, JIMPOCHEM employs multi-layer barrier packaging:
To preserve maximum monoester purity and prevent ester hydrolytic cleavage, store CAS 25339-99-5 in sealed original packaging, away from direct sunlight and heat sources (recommended storage temperature: < 25°C). Properly sealed bags exhibit a stable shelf-life of 24 months from the production date.
Expert answers regarding purchasing, technical performance, microemulsions, and factory supply for CAS 25339-99-5.
CAS 25339-99-5 (Sucrose Monolaurate) has a high HLB (Hydrophilic-Lipophilic Balance) value of approximately 15. This high hydrophilic character allows it to function effectively as a primary water-soluble emulsifier and solubilizer, facilitating the creation of stable Oil-in-Water (O/W) microemulsions, transparent cosmetic lotions, and rapid-dissolving pharmaceutical carriers.
Unlike Polysorbate 20, which is derived from ethylene oxide and may contain trace impurities such as 1,4-dioxane, Sucrose Monolaurate (CAS 25339-99-5) is a 100% bio-based, PEG-free green surfactant synthesized from natural sucrose and edible lauric acid.
