David Craig Ethanol 90% is a high-purity, fast-evaporating ethyl alcohol solution for cleaning, degreasing and general laboratory/surface sanitation. The 90% v/v strength provides rapid drying and excellent solvency for many residues, making it useful in pharmacies, labs, workshops and studios. Use on hard, non-porous surfaces and equipment where water-free cleaning is preferred. Supplied in a sturdy 1 Litre bottle for reliable day-to-day use.

Reasons to Use

• Rapid-cleaning solvent for glass, metal and many plastics

• Surface sanitation on hard, non-porous areas (benchtops, tongs, tools)

• Evaporates quickly leaving minimal residue—ideal where fast turnaround is needed

• Compounding/dispensing environments for general-purpose cleaning, as directed by site SOPs

Reasons Not to Use

• Not for ingestion or use as a beverage; poison/industrial chemical

• Avoid on skin, open wounds, mucous membranes (can cause dryness/irritation)

• Highly flammable—keep away from heat, sparks, static and open flames

• Not for use on delicate coated lenses, acrylics or solvent-sensitive finishes without spot testing

• Do not mix with oxidisers, chlorine bleach, acids or other chemicals

Advantages

• High strength (90%) for fast evaporation and powerful solvency

• Versatile: cleaning, wipe-downs, preparation of lower-strength working solutions

• Large 1 Litre volume offers value for busy environments

Disadvantages

• Flammable liquid requiring careful storage and handling

• Can dry or irritate skin and eyes; use appropriate PPE

• Less ideal than ~70% ethanol for skin antisepsis (evaporates too quickly)

Frequently Asked Questions (FAQ)

Q: Can I dilute this to make 70% ethanol?
A: Yes. To prepare 1 L of 70% v/v from 90%: measure 778 mL of 90% ethanol and add 222 mL of clean (preferably purified) water; mix and label. Always make solutions in a clean, clearly labelled container and follow your site SOPs.

Q: Is 90% better than 70% for disinfection?
A: For hard, non-porous surfaces, both are widely used; contact time and thorough wetting matter most. For skin antisepsis, ~70% is generally preferred due to better penetration before evaporation. Follow your protocol.

Q: Can I use it on electronics?
A: Power off/unplug first. Apply to a lint-free wipe (not directly), use sparingly, and allow to fully evaporate. Check material compatibility; some plastics/coatings may craze.

Q: Is it safe on all plastics and painted surfaces?
A: Not always. Spot test in an inconspicuous area. Avoid known solvent-sensitive materials (e.g., some acrylics, shellac finishes).

Q: What PPE should I use?
A: Use nitrile gloves, eye protection, and ensure good ventilation. For larger tasks, consider a lab coat and local extraction.

Q: How do I store it?
A: Keep tightly capped in the original container, upright, in a cool, well-ventilated area away from ignition sources. Store below the temperature stated on the label and out of reach of children.

Q: Disposal guidance?
A: Treat as flammable chemical waste. Follow local regulations/SDS for disposal; do not pour into drains or the environment.

Q: First aid?
A: Eyes: rinse with water for at least 15 minutes and seek medical advice. Skin: wash with soap and water, apply emollient if dry. Inhalation: move to fresh air. Ingestion: do not induce vomiting; seek urgent medical help.

Q: Is it denatured?
A: Many industrial ethanols are denatured (e.g., with denatonium or ketones) to prevent consumption. Check your bottle for denaturants and use restrictions.
