They are essentially the same thing. Formalin is the histologist's term for a solution of formaldehyde stabilized with a small percentage of methanol. In fact any aqueous solution of formaldehyde probably contains trace MeOH. Such solutions would make effective (but very messy) surface disinfectants. Formaldehyde is probably used more often to disinfect equipment in a fumigation-type process, where a closed space is filled with formaldehyde vapor. I think this is done by heat-sublimation of solid para-formaldehyde.

40 percent formaldehyde is called?
40% aqueous solution of formaldehyde is known as Formalin.
What is the composition of formalin?
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.
Is formaldehyde a deadly chemical?
Yes, but so is rubbing alcohol depending on its strength. Formaldehyde for lab work is often diluted with water, and is then called, "Formalin".
What color is formaldehyde?
The color of formaldehyde liquid depends on what other chemicals are added to it. For example, when potassium carbonate is added the solution acquires a violet-blue color.
How do you prepare 200 ppm formaldehyde solution from percent 37 formalin solution?
200 ppm solution means 200 mg/liter 200 mg = (100 *0.2)/37 = 0.540 g of 37% formaldehyde Vol of 0.540 g of 37 % formaldehyde= 0.540/1.09 = 0.496 mL of 37 % of formaldehyde Therefore: 0.496 mL/1 liter.
Is it safe to use shampoo that has a formalin in its ingredient?
Formalin is formaldehyde in an aqueous solution. Some people have a formaldehyde allergy which could be triggered by contact with formalin.
What is the chemical formula for formalin?
CH2O - Formaldehyde
How does formalin attenuate bacterial virulence?
Formalin is a solution of formaldehyde, which is highly toxic. A third of an ounce of formaldehyde can kill an adult human. Formalin kills the bacteria, but leaves it intact enough to be used for vaccines.
What is formalin?
Formaldehyde is a mixture of 40% formaldehyde, 8% methyl alcohol and 52% water.
40 percent formaldehyde is called?
40% aqueous solution of formaldehyde is known as Formalin.
Formalin is 40 percent aqueous solution of which acid?
Formalin is 40% solution of formaldehyde not an acid.
What residue is form when formalin was evaporated to dryness?
formaldehyde

What is molecular formula of formalin?
A 37% aqueous (water) solution of formaldehyde. The molecular formula of water is H2O and of formaldehyde is CH2O.
What is the name of the aqueous solution of formaldehyde that is available commercially as tissue preservative?
Aqueous solutions of formaldehyde are referred to as formalin. "100%" formalin consists of a saturated solution of formaldehyde (this is about 40% by volume or 37% by mass) in water, with a small amount of stabilizer, usually methanol to limit oxidation and polymerization. A typical commercial grade formalin may contain 10-12% methanol in addition to metallic impurities like aluminum (3 ppm), iron (1 ppm) and copper (1 ppm).
Is formaldehyde a deadly chemical?
Yes, but so is rubbing alcohol depending on its strength. Formaldehyde for lab work is often diluted with water, and is then called, "Formalin".
