70% Isopropyl Alcohol
70% isopropyl alcohol in Lab Grade and Halal-certified USP Grade, in stock and ready to ship.
If you're buying isopropyl alcohol specifically for disinfecting, 70% isn't the weaker option, it's the one built for the job. The water in a 70% solution slows evaporation just enough for the alcohol to penetrate a microorganism's cell wall before it flashes off, which is why hospitals and manufacturers standardize on it instead of 91% or 99%.
Lab Alley carries 70% isopropyl alcohol in Lab Grade and USP Grade, priced and in stock online so you can order without a quote call. USP Grade is Halal certified, with SDS and COA available for both grades, so you can match grade to application whether you're stocking a lab shelf or formulating a hand sanitizer.

70% Isopropyl Alcohol - 2 products About 70% Isopropyl Alcohol
70% isopropyl alcohol is a solution of isopropanol (C3H8O) and water, typically specified as 68.0% to 72.0% IPA by assay, with water making up the remainder. Diluting IPA to 70% doesn't just cut cost; it changes how the solution behaves. The added water slows evaporation just enough for the alcohol to penetrate a microorganism's cell wall before it flashes off, which is the opposite of what most people assume about concentration and disinfecting power. Like all isopropyl alcohol, it's a colorless, volatile, flammable liquid classified as a Class IB flammable liquid with a flashpoint around 12°C (53°F).
COMMON APPLICATIONS
70% isopropyl alcohol is used as a disinfectant and antiseptic agent, a reagent, a general cleaning solvent, and a base for DIY hand sanitizers and disinfectant sprays.
GRADES EXPLAINED
Lab Grade 70% IPA has reasonable purity for general cleaning and disinfecting use, but its exact impurity profile isn't controlled to an official standard, so it isn't suited to drug or medical-device applications. USP Grade 70% meets United States Pharmacopeia purity requirements and carries Halal certification, which is why it's the grade formulators reach for when a product needs a compliance trail behind it.
TYPES & GRADES AT A GLANCE
Is general-purpose 70% IPA for cleaning, disinfecting, and non-critical solvent use.
Meets pharmacopeial purity standards and carries Halal certification for personal-care and pharmaceutical formulation.

Frequently Asked Questions
What's the difference between Lab Grade and USP Grade 70% isopropyl alcohol?
Lab Grade has solid purity for cleaning and disinfecting, but it isn't tested against a pharmacopeial method, so it's not the right call for anything touching a drug formulation or medical device. USP Grade 70% is tested to United States Pharmacopeia requirements and carries Halal certification, which is why it's the grade to use when a product needs a compliance trail behind it.
Why is 70% the standard concentration for disinfecting instead of 91% or 99%?
The water in a 70% solution slows evaporation just enough for the alcohol to get into a microorganism's cell wall before it flashes off. Push the concentration to 91% or 99% and it can evaporate too fast to finish the job on a surface. That's backwards from what most people assume, and it's exactly why hospitals and manufacturers standardize on 70% for hand rubs and surface disinfectants.
Do I need a permit to buy 70% isopropyl alcohol?
No. Isopropyl alcohol was never a beverage-alcohol product, so there's no TTB permit or formula paperwork involved, at either grade.
Is 70% isopropyl alcohol Kosher or Halal certified?
Our USP Grade 70% is Halal certified but not Kosher. Lab Grade 70% doesn't carry either certification. If a label claim matters for your formulation, USP is the one to order.
Can 70% isopropyl alcohol be shipped to a residential address?
No. Like our other flammable chemicals, it can only ship to a business, school, university, or lab address. If a residential address gets used at checkout, we'll remove the item from your order before it ships, so use a commercial address up front to avoid the delay.
Which grade should I use for a hand sanitizer or personal-care formulation versus general cleaning?
For anything that touches skin or needs a documented compliance trail, USP Grade 70% is the safer choice since it's tested to pharmacopeial standards and Halal certified. For general cleaning and disinfecting where cost matters more than a certified purity spec, Lab Grade 70% does the job for less.
How is 70% isopropyl alcohol different from 91% or 99%?
Higher concentrations evaporate faster and leave less residue, which is why 91% and 99% are the ones used for electronics cleaning and moisture-sensitive lab work. 70% trades some of that fast evaporation for better disinfecting performance, since the extra water gives the alcohol more time to work before it flashes off.
Can I buy 70% isopropyl alcohol in drums or totes?
Yes. Both Lab and USP Grade 70% ship up to 55-gallon drums, with 270-gallon totes also available. Contact us through Bulk & Custom Chemicals for volume pricing.
