Glutaraldehyde
Glutaraldehyde · GDA
A candidate non-oxidizing ingredient for industrial recirculating water, papermaking and oilfield water. Purchasing should be supported by validation under actual fluid and contact conditions; industrial grades and formulated products dedicated to medical equipment must be considered separately.
Product uses
An industrial non-oxidizing biocidal ingredient with defined uses.
Bring an existing model or purchasing specification directly into the discussion.

- Chemical identity / CAS
- 111-30-8Glutaraldehyde active ingredient ↗
- Physical form / Type
- Industrial products are commonly aqueous solutions; confirm color and formulation components for the specific product.
- Key purchasing comparisons
- Active ingredient and formulation compositionpH, temperature and contact conditionsOilfield polymers and other additivesOccupational exposure and metering conditions
- Packaging and delivery
- Confirm liquid packaging, closed-transfer connections, container materials and residual-liquid management; purchasing documents must distinguish single-active aqueous solutions from blends.
Identity and physical form identify the product; specific concentration, grade, packaging and uses are governed by mutually confirmed formulated-product documents.
01 / Product and applications
Uses and product form
Chemical identity / Technical type
Glutaraldehyde, a dialdehyde compound; blends containing quaternary ammonium compounds or other ingredients require complete-formulation evaluation.
Appearance and delivery form
Industrial products are commonly aqueous solutions; actual color, content and components must match supply.
Identity note
Glutaraldehyde is also called glutaral or pentanedial. The CAS identifies the dialdehyde compound; industrial solutions and quaternary ammonium blends still require full SDS composition checks. A blend is not pure glutaraldehyde.
02 / Specification selection
Key purchasing parameters
| Items to confirm | Relevance to purchasing and use |
|---|---|
| Active ingredient and formulation composition | Distinguish single-active products and blends. |
| pH, temperature and contact conditions | Evaluate achievable efficacy. |
| Oilfield polymers and other additives | Avoid disrupting fluid preparation, demulsification and reinjection. |
| Occupational exposure and metering conditions | Implement actual SDS requirements in the facilities. |
Include parameters, test methods and acceptance checkpoints in purchasing requirements to compare specifications.
03 / Applications and limits
Applications and conditions of use
These are starting points for conditional verification. Specific product suitability still requires joint confirmation through product documents, operating conditions and destination requirements.
Additional checks before use
- Industrial grade is not automatically suitable for medical-device disinfection.
- Biocidal capability must not be described as solving every SRB or biofilm problem.
- Purchase validated blends; this page does not authorize on-site mixing.

06 / Frequently asked questions
Purchasing FAQs
Can it be used in all oilfield water?
No. Validate salinity, temperature, composition and target organisms using actual water samples.
Is industrial glutaraldehyde equivalent to medical disinfectant?
No. Product uses, composition, quality and equipment requirements differ.
When should a blend be considered?
When a single-active product does not meet objectives and complete-product evidence exists, compare efficacy and fluid compatibility.

Operational troubleshooting
Water microbial counts fall after glutaraldehyde treatment: why do pipe-wall problems recur?
Water samples and pipe walls represent different targets. Recurring slime or corrosion requires checks of attached layers, stagnant sections and recontamination; one water count cannot establish system recovery.

Limits of use
Why cannot industrial glutaraldehyde and medical disinfectant products be purchased by matching concentration?
The same active ingredient does not imply identical product uses, auxiliary components or validation procedures. Industrial water and medical equipment require their respective evidence, which is not interchangeable.
