Direct supply of standardized plant extracts, high-purity monomers, and water-distilled bioactive fractions manufactured under audited GMP standards.
An authoritative breakdown of water distillation thermodynamics, aromatic hydrosol separation, and terpene preservation for high-end pharmaceutical and cosmetic applications.
Water distillation (hydro-distillation) is the premier extraction method for heat-sensitive botanicals, delicate floral aromatics, and medical-grade essential oils. By fully immersing raw botanical matrices in ultrapure aqueous media heated under vacuum-controlled conditions, water distillation prevents thermal degradation, thermal burning, and pyrolysis of volatile mono- and sesquiterpenes.
Unlike standard steam distillation where hot steam may channel through raw materials creating uneven thermal pockets, hydro-distillation provides uniform heat transfer via hydrostatic pressure. This guarantees complete release of active aromatic volatile fractions while co-producing nutrient-dense hydrosols (aromatic waters) enriched with water-soluble polyphenols.
Our extraction plants operate specialized stainless steel 316L hydro-distillation units equipped with closed-loop Clevenger-type condensers and micro-fractional column separations. Every batch delivered to manufacturing partners serving the Bangkok and Southeast Asian markets undergoes Gas Chromatography-Mass Spectrometry (GC-MS) and High-Performance Liquid Chromatography (HPLC) testing.
This rigorous monitoring ensures strict adherence to international pharmacological standards, zero synthetic solvent carryover, zero heavy metal contamination, and low pesticide residues below EU and Thai FDA detection limits.

Understanding how water-distilled essential oils and botanical active compounds (such as Sophora Japonica Quercetin) power local B2B commercial manufacturing across Greater Bangkok.
Bangkok stands as the spa capital of Southeast Asia. High-end wellness retreats in Sukhumvit, Silom, and along the Chao Phraya River require 100% pure water-distilled hydrosols and essential oils for aromatherapy, holistic topical massage oils, and natural climate-resilient facial mist sprays that resist tropical ambient humidity.
Bangkok’s dense urban environment drives consumer demand for Anti-PM 2.5 and UV-repair skincare products. Local OEM skincare labs integrate pure water-distilled extracts with potent bioflavonoids like Liposomal Quercetin 50% and Sophora Japonica extracts to formulate topical antioxidants that neutralize free-radical smog damage.
Thailand's functional beverage market is expanding rapidly. Contract beverage bottlers in industrial zones near Bangkok utilize water-soluble botanical fractions and hydro-distilled herbal extracts to create clear, shelf-stable, sediment-free functional drinks, sports recovery shots, and traditional Thai botanical tonics.
For dietary supplement manufacturers supplying pharmacy chains across Bangkok, precise particle mesh size and flowability are non-negotiable. Our high-density Quercetin Dihydrate 98% Granular enables high-speed direct compression tableting with zero die-sticking.
Aligning raw material purchasing with Thailand’s Bio-Circular-Green (BCG) Economic Model and Thai FDA compliance mandates for international B2B buyers.
Thailand’s government policy heavily promotes the BCG economic model in personal care and supplements. Formulators in Bangkok actively migrate away from synthetic chemical ingredients toward solvent-free water distillation extracts, organic Sophora Japonica extracts, and zero-waste botanical processing technologies.
Importing botanical extracts into Thailand requires rigorous regulatory documentation. Every batch we manufacture for distributors and end-users in Bangkok comes complete with batch-specific COAs, GC-MS terpene maps, heavy metal screenings (Pb, Cd, Hg, As), pesticide residue panels, and allergen-free declarations ready for Thai FDA submission.
Speed-to-market is critical. We maintain optimized supply lines directly to Bangkok Ports (Laem Chabang and Klong Toey) and Suvarnabhumi Airport (BKK) cold-chain cargo facilities, offering sea and express air shipments with moisture-proof vacuum packaging to withstand tropical humidity.
A specialized extraction manufacturer delivering fully traceable plant powders, pure monomers, CO2 supercritical oleoresins, and hydro-distilled essential oils.
Founded in 2014, RAAG Biotech Co., Ltd. operates a modern, GMP-audited industrial manufacturing complex spanning primary raw material processing, reflux extraction, column chromatography purification, and automated water-distillation lines.
We do not operate as an intermediary trading firm. Our dedicated team of 80+ employees and in-house analytical chemists oversee contracted GAP (Good Agricultural Practices) planting bases. This ensures every kilogram of botanical raw material—from Sophora Japonica flowers used for high-purity Quercetin extraction to delicate aromatic plants—can be traced directly back to its harvest origin, soil log, and drying parameters.
