As clean-label regulations tighten globally, food, pharmaceutical, and cosmetic brands are seeking high-stability, sustainable, natural alternatives to synthetic colorants. Water-soluble chlorophyll—primarily in the form of Sodium Copper Chlorophyllin (CAS 28302-36-5)—has emerged as a premium green pigment with outstanding thermal and photostability.
Global enterprises demand Kosher, Halal, ISO 9001, and USP/EP compliance to meet strict regulatory boundaries across FDA, EFSA, and regional food authorities.
Replacing standard green lakes requires sodium copper chlorophyllin that maintains molecular integrity across wide pH arrays and pasteurization profiles.
B2B buyers prioritize manufacturers with large-scale extraction capacity (over 2,000 tons annually) to buffer agricultural harvest volatility.
Unlike fat-soluble chlorophyll which is highly sensitive to heat and acidic media, water-soluble chlorophyll undergoes a precise chemical extraction process known as saponification, followed by copperization. The magnesium ion in the center of the porphyrin ring is substituted with copper, converting the unstable oil-soluble compound into a water-soluble salt. This molecular structure yields a deep green color that remains robust in aqueous solutions.

Industrial scale sourcing of water-soluble chlorophyll involves balancing raw leaf supply chains (typically derived from premium alfalfa or spinach) with high-capacity chemical engineering. Jiangxi Hairui Natural Plant Co., Ltd. addresses the four major procurement bottlenecks:
The essential oil usually extracted by steam distillation or cold compression. The raw materials used in the production of essential oils, food, and cosmetics are the second largest category of our products, such as camellia oil, eucalyptus oil, oregano oil, and peppermint oil. Hairui Natural Plant selects high-quality raw materials with high standards, strictly controlling and supervising the entire production process.

Base oil, also known as medium oil or carrier oil, is usually extracted by cold compression. Single essential oils cannot be rubbed directly on the skin; they must be diluted in a carrier oil before they can be widely used on our body's skin. Many carrier oils have medical properties of their own. We extract a wide variety of premium vegetable oils.

Herbal extract is typically separated by cooling or precise solvent extraction from selected plants. Premium final products come from high-quality raw materials. We boast a 5000+ acre self-owned raw material production base, where the whole process from seed selection, seedling raising, planting, and harvesting is fully controlled.

The conversion of hydrophobic chlorophyll into a hydrophilic state requires a multi-step thermodynamic process. Native chlorophyll consists of a lipid-soluble phytol group and a magnesium-centered porphyrin ring. Saponification breaks the ester linkage, removing the phytol tail and producing water-soluble chlorophyllin.
However, the central magnesium ion is structurally unstable and prone to degradation under low pH or elevated temperature. To address this, our R&D facility utilizes a metal exchange process: the magnesium ion is replaced with a copper ion under controlled temperature (60°C - 80°C) and pressure conditions. The resulting Sodium Copper Chlorophyllin is highly stable, boasting high solubility in water and resistance to light degradation.
Our technical team designs custom delivery systems for various industrial sectors:
Essential oil and botanical extracts usually extracted from the flowers, leaves, seeds, roots, bark, and fruits of plants. Developed for versatile application across key industrial fields.
For example, sweet orange oil is a natural orange peel extract. Derived from nature without residual risk, it has unique advantages in safeguarding ecological systems. Orange oil promotes crop respiration and photosynthesis, enhancing growth. It can be used as an adjuvant or alone as a pesticide, offering wide control over pests and diseases.
Castor oil promotes hair growth and health. Massaging a small amount into the scalp during washing aids absorption, moisturizing the hair and leaving it shiny. Castor oil is also beneficial for preventing and treating minor scalp irritation.
Evening primrose oil contains active components like r-linolenic acid, magnesium, zinc, copper, and vitamins C, E, B6, and B5. The most abundant components are about 70% linoleic acid (LA) and 7-10% gamma-linolenic acid (GLA). It is encapsulated for oral use to support cardiovascular wellness and ease physiological changes.
In 1926, French chemist René-Maurice Gattefossé discovered the soothing properties of lavender oil on skin burns, coining the term "aromatherapy". Natural essential oil molecules stimulate olfactory sensors that link to the limbic system, supporting emotional regulation, stress relief, and overall wellness.
The future of water-soluble chlorophyll lies in nano-encapsulation and emulsion systems. Standard chlorophyllin is sensitive to acidic environments (precipitating out at pH levels below 5.5). Jiangxi Hairui's R&D division is actively testing polysaccharide encapsulation models (using gum arabic and modified starches) to shield the chlorophyllin complex. This innovation allows for stable, natural green coloring in low-pH carbonated beverages and functional yogurts without precipitation.
We work closely with global regulatory consultants to verify that our exports comply with the domestic laws of the importing nations:
Natural chlorophyll is fat-soluble (hydrophobic) and contains a phytol tail and a magnesium core. In water-soluble chlorophyll (Sodium Copper Chlorophyllin), the phytol tail is cleaved via saponification and the magnesium ion is replaced with copper. This modification makes it highly soluble in water and significantly more stable against UV light and thermal processing.
Sodium copper chlorophyllin is highly stable in neutral to alkaline solutions (pH 7.0 to 11.0). In acidic formulations (below pH 5.5), the sodium salt can convert back to its acid form, resulting in precipitation and a slight color shift. For acidic beverages, we recommend utilizing our encapsulated or stabilized variants.
Each batch undergoes comprehensive analysis. We utilize High-Performance Liquid Chromatography (HPLC) to verify colorant composition, Atomic Absorption Spectroscopy (AAS) to ensure free copper limits stay well below regulatory thresholds (typically <0.025%), and ICP-MS for heavy metal profiling.
Yes. All our botanical extractions, including water-soluble chlorophyll derivatives, are certified Kosher and Halal, ensuring clean and compliant labeling for food and supplement products globally.
MOQs depend on product specifications, starting from 1kg to 25kg (drum packaging). Standard products can be shipped immediately, while customized color strengths or formulations have a typical production lead time of 7–14 days.
