водещ параграф:
Even the most advanced surfactants can lose their performance if not stored properly. Decomposition during storage is one of the most common causes of quality decline in chemical formulations.

откъс от параграф:
To prevent decomposition of surfactants in storage, maintain a cool (20–40°C), dry, and airtight environment, avoid exposure to moisture, strong acids, or oxidizers, and use high-quality packaging materials such as HDPE drums or stainless-steel tanks. Regular testing of acid value, color, and pH helps ensure long-term stability.

Преходен параграф:
Whether you’re handling textile wetting agents, coating dispersants, or phosphate ester surfactants, proper storage determines product longevity and safety. This guide from Donghong Chemical explains the key factors that cause surfactant decomposition — and how to effectively prevent them in industrial and warehouse conditions.

Why Surfactants Decompose During Storage

водещ параграф:
Surfactants are designed for chemical stability, yet several environmental and chemical factors can accelerate their degradation.

откъс от параграф:
Decomposition typically results from hydrolysis, oxidation, microbial growth, or thermal stress. Each mechanism alters molecular structure, leading to color change, odor formation, and reduced surface activity.

Common Causes of Surfactant Degradation:

Cause	Description	Result
Hydrolysis	Reaction with water due to moisture ingress	Acid or alcohol formation, drop in pH
Oxidation	Reaction with oxygen or air exposure	Discoloration, rancid odor
High Temperature	Speeds up hydrolysis and oxidation	Viscosity change, loss of functionality
UV Exposure	Breaks down molecular bonds	Color shift or precipitate formation
Microbial Growth	Occurs in aqueous surfactants	Spoilage and foul odor

Пример:
Phosphate ester surfactants like AEO-3 or NP-10 can hydrolyze if moisture enters the storage container, leading to higher acid value and reduced emulsification efficiency.

Optimal Storage Conditions for Surfactants

водещ параграф:
The simplest way to protect surfactants is by controlling their environment — temperature, humidity, and exposure.

Strong bases or acids	Chemical neutralization or hydrolysis
Reactive metals (iron, copper, zinc)	Discoloration or catalytic breakdown
Water or steam	Promotes hydrolysis and pH drift

5. Recommended Packaging

• HDPE drums or IBC tanks (1000 L) for liquid surfactants.
• Epoxy-lined steel containers for industrial-scale storage.
• Avoid mild steel or uncoated metal tanks for acidic esters.

Monitoring Product Stability

водещ параграф:
Even with ideal storage, periodic testing ensures product integrity and prevents unnoticed degradation.

откъс от параграф:
Regular quality monitoring helps maintain consistency and provides early detection of chemical changes.

Key Quality Parameters to Monitor:

Параметър	Ideal Range	Indicator of Degradation
Външен вид	Clear, color ≤30 APHA	Yellowing or haze formation
pH (разтвор 5%)	5–8	Drop indicates hydrolysis
Стойност на киселинност (mgKOH/g)	0.1–0.3 (neutral type)	Increase indicates decomposition

водещ параграф:
Phosphate esters are among the most stable surfactants — but small handling mistakes can still shorten their shelf life.

откъс от параграф:
Implementing a few preventative measures can extend shelf life up to 24 months or longer under proper conditions.

1. Use Inert Gas Blanketing

• Fill headspace in drums or tanks with nitrogen.
• Prevents oxidation and color degradation.
• Recommended for P204, TBP, TEP, and AEO-3 phosphate esters.

2. Keep Drums Sealed and Dry

• Always close container lids tightly after sampling.
• Use desiccant packs for long-term sealed storage.

3. Maintain Storage Rotation

• Adopt the FIFO (First In, First Out) principle.
• Regularly record batch numbers and storage durations.

4. Avoid Frequent Heating

• Some facilities heat containers for fluidity — this accelerates breakdown.
• Instead, keep products in temperature-controlled warehouses.

5. Add Stabilizers if Necessary

• For sensitive formulations, small doses of antioxidants or chelating agents can extend life.
• Always consult the supplier before modifying chemical composition.

Резултат:
Proper storage can maintain acid value, color, and activity nearly identical to production specifications for over two years.
