cURL Too many subrequests.

སྔོན་འགྲོའི་དོན་ཚན།:
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.

ཟུར་བཀོད་དོན་ཚན།:
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.

འཕོ་འགྱུར་དོན་ཚན།:
Whether you’re handling textile wetting agents, coating dispersants, or phosphate ester surfactants, proper storage determines product longevity and safety. This guide from དོང་ཧོང་རྫས་འགྱུར་ explains the key factors that cause surfactant decomposition — and how to effectively prevent them in industrial and warehouse conditions.

Why Surfactants Decompose During Storage

སྔོན་འགྲོའི་དོན་ཚན།:
Surfactants are designed for chemical stability, yet several environmental and chemical factors can accelerate their degradation.

ཟུར་བཀོད་དོན་ཚན།:
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

བསྟན་པའི་སྦྱོར་བའི་སྐབས།
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

སྔོན་འགྲོའི་དོན་ཚན།:
The simplest way to protect surfactants is by controlling their environment — temperature, humidity, and exposure.

ཟུར་བཀོད་དོན་ཚན།:
Follow these universal storage conditions for both anionic and nonionic surfactants:

1. Temperature Control

• Ideal storage temperature: 20–40°C.
• Avoid exposure to freezing (<10°C) or overheating (>50°C).
• Install temperature sensors and insulation in large storage tanks.
• High temperatures accelerate hydrolysis and oxidation, shortening shelf life.

2. Moisture and Air Protection

• Keep containers sealed tightly after each use.
• cURL Too many subrequests. nitrogen blanketing for bulk storage to prevent oxidation.
• Avoid storing near humid or wet areas — moisture triggers decomposition.

3. Light Protection

• cURL Too many subrequests. shaded or covered warehouses.
• cURL Too many subrequests. opaque or UV-resistant containers for light-sensitive products.
• Direct sunlight can degrade color and reduce active ingredient concentration.

4. Compatibility and Segregation

Incompatible Substance	Risk
Strong oxidizers (e.g., peroxides)	Fire and decomposition hazard
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

སྔོན་འགྲོའི་དོན་ཚན།:
Even with ideal storage, periodic testing ensures product integrity and prevents unnoticed degradation.

ཟུར་བཀོད་དོན་ཚན།:
Regular quality monitoring helps maintain consistency and provides early detection of chemical changes.

Key Quality Parameters to Monitor:

පරාමිති	Ideal Range	Indicator of Degradation
ལུས་སྟོན	Clear, color ≤30 APHA	Yellowing or haze formation
cURL Too many subrequests.	5–8	Drop indicates hydrolysis
ཨསེད་བརྗེད་ཚད (mgKOH/g)	0.1–0.3 (neutral type)	Increase indicates decomposition
བཞའ་ཚན་(%)	≤0.1	Excess leads to instability
Viscosity	Stable within ±10%	Increase shows polymerization or oxidation
cURL Too many subrequests.	Neutral or mild	Sharp odor signals spoilage

Testing Frequency:
For most surfactants, test every 3–6 months if stored long-term. For high-value esters like TEP or TOP, perform monthly sampling in tropical climates.

Donghong Chemical’s in-house QC laboratories use GC, FTIR, and Karl Fischer titration to ensure stability for every production batch.

How to Extend Shelf Life of Phosphate Ester Surfactants

སྔོན་འགྲོའི་དོན་ཚན།:
Phosphate esters are among the most stable surfactants — but small handling mistakes can still shorten their shelf life.

ཟུར་བཀོད་དོན་ཚན།:
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.

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