Azlok Ethanol 99.9% (Denatured) is a high-purity, colourless alcohol used mainly as a solvent and cleaning agent. It is denatured, which means additives have been mixed in to make it unfit for drinking — so it is meant for laboratory, industrial, cosmetic and DIY use, never for consumption. At roughly 99.9% purity, it has very little water, which makes it fast-evaporating and effective for jobs where residue and moisture are a problem.
What denatured ethanol actually is
Ethanol is a flammable alcohol found in many everyday products. The word "denatured" simply tells you that a small amount of a bittering or toxic agent has been added so the alcohol cannot be misused as a beverage. This does not affect its performance as a solvent. Because this grade is nearly anhydrous (very low water content), it behaves differently from the 70% or 95% dilutions you may have seen, dissolving oils and resins cleanly and drying without leaving watermarks.
Common uses
- Surface cleaning and degreasing: Cuts through oily films on glass, metal and electronics-adjacent surfaces, evaporating quickly.
- Laboratory and research work: A reliable solvent for reactions, sample preparation and general lab cleaning.
- Cosmetics and perfumery: Used as a carrier and solvent base in fragrances, sprays and formulations (in denatured, non-ingestible products).
- Extractions and tinctures: Popular in DIY and craft work for pulling out botanical resins, oils and colours — for external or non-food formulations only, since this grade is denatured.
- Thinning and dissolving: Helpful for dissolving shellac, certain dyes and some adhesives.
- Fuel applications: Ethanol can serve as a clean-burning fuel in suitable burners and stoves.
How to use it
For cleaning, apply a small amount to a lint-free cloth rather than pouring directly onto surfaces, and always test a hidden spot first — high-strength alcohol can strip some paints, plastics and finishes. For extractions or cosmetic bases, follow a tested recipe and measure carefully; more alcohol is not always better. Work in small batches until you understand how quickly it evaporates.
Safety and handling
Ethanol at this strength is highly flammable, so treat it with respect.
- Keep it away from flames, sparks and heat. Do not use near a gas stove, candle or anything that could ignite the vapour.
- Ventilate well. Use it in an open or well-aired space to avoid breathing concentrated fumes.
- Wear gloves and eye protection for extended handling; it can dry and irritate skin.
- Do not drink it. Denatured ethanol is toxic if swallowed. Keep it firmly out of reach of children and pets.
- Wipe up spills promptly and store the container tightly closed.
If you have sensitive skin, do a small patch test before using any homemade formulation on your body, and never assume denatured alcohol is food-safe.
Buying and storage tips
Buy the quantity you will realistically use — the 1000 mL Azlok bottle suits hobbyists, small makers and lab users without leaving stock sitting for years. Store it upright in a cool, dark place away from direct sunlight and heat sources, with the cap sealed to slow evaporation and prevent it absorbing moisture from the air. Check that labels stay legible so anyone in the house knows the contents are flammable and not for drinking. For most casual users, a single well-sealed bottle stored responsibly will last a long time.
FAQ
Can I drink denatured ethanol?
No. Denatured ethanol has additives that make it toxic and unpalatable. It is strictly for external, laboratory, industrial and DIY use, never for consumption.
What is the difference between 99.9% and 95% ethanol?
The percentage refers to purity. At 99.9% there is almost no water, so it evaporates faster and leaves less residue — useful for cleaning and moisture-sensitive work. 95% and 70% dilutions contain more water and are often preferred where a slower evaporation or milder strength is wanted.
Is it safe to use on electronics or glass?
It works well on glass and many surfaces because it dries cleanly. For anything delicate, test a small area first and ensure the item is unplugged and completely dry before use, since the liquid is flammable.
How should I store it at home?
Keep it in a cool, dark, well-ventilated spot, tightly closed, away from heat, flames and children. Store the bottle upright to avoid leaks.
Can it be used for herbal tinctures?
It can be used for external or non-ingestible extractions, but because this grade is denatured it is not suitable for anything you plan to consume. Use a food-grade product for edible preparations.
