Product Description
Brand owners call us with the same problem: their liquid chlorophyll was vibrant green at production, but by month 4 it's olive brown. The issue isn't the raw material—it's that chlorophyll is the most color-unstable active you can put in a liquid, and most manufacturers treat it like any other ingredient.
We've produced 80+ liquid chlorophyll formulations. The #1 reason brands switch to us: color degradation at month 4-6 that their previous manufacturer couldn't solve.
Why Liquid Chlorophyll Fails—And How We Fix It
The 3 Stability Challenges Unique to Liquid Chlorophyll
Liquid chlorophyll products face three unique stability challenges that most manufacturers ignore or don't know how to handle:
1. Photo-Degradation Control
Chlorophyll is extremely sensitive to UV light. In clear bottles, it can degrade by 40% within 30 days. UV exposure breaks down the porphyrin ring structure, causing the vibrant green to fade and shift toward yellow-brown.
Our solution: Amber glass packaging + UV-absorbing additive + nitrogen blanket throughout production and packaging. Result: 6-month color difference ΔE<2.
2. pH-Stabilized Formulation
Chlorophyllin is stable in alkaline conditions, but when pH drops below 5.0, the color shifts from green to olive-brown. Most manufacturers don't monitor or control pH throughout shelf life.
Our solution: Proprietary buffered system that locks pH at 6.5-7.5, ensuring 12 months without color shift.
3. Preservative Compatibility
Sodium benzoate—a common preservative—reacts with chlorophyllin and causes accelerated green fading. Many manufacturers use it because it's cheap, not realizing the compatibility issue.
Our solution: Potassium sorbate + mild organic acidulant combination. Both preservation efficacy and color stability achieved.

Real Case: How We Solved a 4-Month Color Problem
In 2024, a US supplement brand came to us after their previous manufacturer's liquid chlorophyll product began turning olive-brown at month 4. Their customers were posting comparison photos on social media. After switching to Runxin with our amber glass + buffered formula + potassium sorbate system, their first batch has been on shelf for 14 months with no visible color change. They've since expanded from 2 SKUs to 5.
Frequently Asked Questions
Q: Why does my liquid chlorophyll turn brown after a few months?
A: Two primary causes: (1) Photo-degradation—chlorophyll breaks down under UV light, especially in clear packaging. Even ambient light exposure over time causes cumulative damage. (2) pH shift—when the formula's pH drops below 5.0, chlorophyllin changes from green to olive-brown. We solve both with amber glass packaging + UV additives + pH-buffered system.
Q: What's the difference between chlorophyll and chlorophyllin for liquid products?
A: Chlorophyllin (copper sodium chlorophyllin) is more commonly used in supplements because the copper center makes it more stable than pure chlorophyll. However, chlorophyllin still requires proper pH control (6.5-7.5) and must be protected from UV light. The key is not just choosing chlorophyllin—it's how the entire formulation and packaging system supports its stability.
Q: Can I use a clear bottle for my chlorophyll product?
A: We don't recommend it. In clear PET bottles, chlorophyll can degrade by 30-40% within 30 days under normal lighting conditions. If shelf appeal matters (and it should for a green product), amber glass is essential. If cost is a concern, PET with UV-blocking additives is a compromise—but expect some color shift over time.
Q: How do you prevent color degradation during production?
A: Three measures: (1) Nitrogen blanket throughout production and filling—we displace oxygen that accelerates oxidation. (2) Temperature control—we keep production below 25°C to slow degradation reactions. (3) Light-protected filling lines—our facility uses yellow-safe lighting in production areas and rapid packaging transfer.
Q: What chlorophyll source do you recommend?
A: Depends on your positioning:
- Alfalfa: Most cost-effective, widely accepted, good chlorophyllin content
- Mulberry Leaf: Higher chlorophyllin content, premium perception, often combined with other botanicals
- Spirulina: Strong plant-based story, appeals to clean-label consumers, deep green color
All sources come with Certificate of Analysis per batch, including chlorophyllin content verification.
Q: What is your MOQ and lead time?
A: MOQ is 2,000 bottles per SKU. Sample production takes 5-7 working days. Bulk production takes 15-20 working days after sample approval. For new formulations, expect 20-30 working days for first sample batch.
Q: Can you help with label design and regulatory compliance?
A: Yes. We work with label designers for private label and custom design projects. For regulatory compliance, we provide GMP certificates, COAs, and can support FDA registration documentation. Compliance responsibility ultimately rests with the brand owner, but we provide all necessary manufacturing documentation.
