Tea Saponin

Description

Noksoul operates a GMP-, ISO- and HACCP-certified production base in the Hongjiang High-tech Zone of Hunan Province, a region rich in Camellia oleifera (oil-tea) resources. We specialize in Tea Saponin, a natural triterpenoid saponin mixture isolated from oil-tea seed (Camellia oleifera Abel. seed) through controlled water extraction, foam/resin enrichment, chromatography and low-temperature spray drying. Our production workflow isolates and standardizes tea saponin to 60%, 80% or 90% by HPLC, delivering consistent natural-surfactant material for agrochemical adjuvant formulators, daily-use chemical and cosmetic manufacturers, concrete and gypsum foaming-agent producers, aquaculture suppliers and pharmaceutical intermediate developers worldwide.

Why Choose Noksoul Tea Saponin

• Natural Plant-Derived Non-Ionic Surfactant.  Tea saponin is a well-characterized triterpenoid saponin mixture with natural emulsifying, foaming, wetting and dispersing activity. Sourced from Camellia oleifera seed, it is a biodegradable alternative to synthetic surfactants, suitable for eco-positioned detergents, shampoos, cosmetics and agrochemical formulations.
• Controlled Water Extraction Preserving Surface Activity.  Manufacturing applies optimized water extraction, resin enrichment and low-temperature spray drying. This route preserves saponin foam and emulsifying activity, in contrast to harsh high-temperature processing that hydrolyzes glycosidic bonds and lowers surface activity.
• HPLC-Driven Batch-to-Batch Standardization.  Every production lot is quantified by HPLC for tea saponin content (60%/80%/90%), alongside foaming height and stability testing. Multi-analyte documentation gives formulators full batch traceability to support product positioning and quality consistency.
• Controlled Impurity and Residual Management.  Our quality system monitors residual solvents (in compliance with ICH Q3C), ash, moisture and microbial load. Each batch is controlled for processing-related contaminants to meet customer specifications.
• Heavy-Metal and Microbiological Compliance.  Each lot undergoes ICP-MS heavy-metal screening, full microbiological panel testing and critical safety parameter verification before commercial release, in line with our established ISO / GMP / HACCP quality system.
• Complete Export Documentation.  COA, MSDS, HPLC assay, heavy-metal test report and batch-traceability records accompany every shipment. With over two decades of industry expertise and local oil-tea resource integration, our materials serve customers across the Americas, Europe, Southeast Asia and beyond.

What Is Tea Saponin

Botanical Source and Composition

Tea saponin (CAS 8047-15-2, C57H90O26, ~1191 g/mol) is a triterpenoid saponin mixture naturally accumulated in the seed of Camellia oleifera Abel. (oil-tea tree). As a natural non-ionic surfactant, it produces rich, stable foam and exhibits emulsifying, wetting, dispersing and solubilizing properties. It also exhibits documented anti-inflammatory, analgesic, anti-fungal and insect-repellent activities, which underpin its broad use across agrochemicals, daily-use chemicals, cosmetics, construction foaming agents, aquaculture and pharmaceutical intermediates.

Standardized Tea Saponin vs. Crude Oil-Tea Seed Powder

Crude oil-tea seed powder / defatted seed meal contains tea saponin alongside large amounts of oil, protein, polysaccharide, fibre and pigments; saponin content typically ranges only around 10–15% and varies widely with seed origin, storage and processing. Standardized tea saponin produced via water extraction, resin enrichment, chromatography and low-temperature drying is highly concentrated to 60%, 80% or 90% by HPLC, enabling predictable foaming/emulsifying performance and reliable batch-to-batch consistency for finished formulations.

Production Process

Incoming Camellia oleifera seed raw material is inspected for botanical identity, initial saponin content, heavy-metal levels and microbiological status prior to manufacturing.

• Raw-Material Pretreatment — Dried oil-tea seed is cleaned, crushed and defatted to remove residual oil, then screened to obtain a uniform defatted seed meal. Botanical identity is confirmed before extraction.
• Water Extraction — Defatted meal undergoes controlled hot-water circulation extraction to solubilize saponins, maximizing saponin yield while limiting co-extraction of proteins and polysaccharides.
• Clarification and Concentration — The extraction liquor is clarified by filtration and centrifugation, then concentrated by low-temperature vacuum evaporation to obtain a crude saponin extract.
• Resin / Column Chromatography Enrichment — Crude extract is loaded onto macroporous adsorption resin or chromatographic resin for selective adsorption and elution, separating tea saponin from sugars, pigments and other impurities.
• Low-Temperature Drying for Final Standardization — Purified saponin solution is concentrated and low-temperature spray-dried to obtain a light yellow to yellow-brown powder, assayed to the target 60% / 80% / 90% HPLC grade.
• Quality Release and Packaging — Dried powder is assayed for saponin content by HPLC, foam height and stability, moisture, ash, residual solvents, heavy metals and microbiological safety. Qualified material is packed into double-layer PE inner bags with desiccants, then sealed within light-proof, moisture-barrier fibre drums.

Functional Properties & Benefits

• Natural Surfactant: Emulsifying, Foaming, Wetting.  Tea saponin produces rich, fine and stable foam, and acts as a natural emulsifier, wetting agent and dispersant. It is mild on skin and biodegradable, making it a preferred green alternative in shampoos, body washes, facial cleansers and natural detergents.
• Agrochemical Adjuvant Activity.  As a natural wetting and spreading agent, tea saponin improves the coverage and adhesion of agrochemical sprays, and exhibits mild insect-repellent and anti-fungal properties, supporting eco-friendly pesticide and fertilizer formulations.
• Anti-Inflammatory and Skin-Soothing Support.  Tea saponin shows documented anti-inflammatory and analgesic activity, and is used in skin-soothing and anti-irritant cosmetic formulations due to its mild, plant-derived cleansing profile.
• Foaming Agent for Construction.  Stable foam-generating performance makes tea saponin widely used as a natural foaming agent in aerated concrete, gypsum and light-weight building materials.
• Aquaculture and Other Industrial Uses.  Tea saponin is used in aquaculture pond management (fish detox, snail and pest control) and as a natural emulsifier and dispersant across textile, leather and environmental applications.

Applications

• Natural Cosmetics and Daily-Use Chemicals.  Supplied as a natural foaming, cleansing and emulsifying raw material for shampoos, body washes, facial cleansers, soaps and shower gels, positioned for plant-based, mild and biodegradable lines.
