Abstract

A formula and method for rapid neutralization of formaldehyde solutions and vapor is provided. The invention comprises a matrix or medium upon which a mixture of urea, acid, calcium chloride and water is applied and dried. When the treated matrix or medium comes into contact with formaldehyde solution or vapor, the hydroscopic nature of the calcium chloride dried on the medium quickly absorbs and neutralizes the formaldehyde, irreversibly changing the formaldehyde molecules to a nonhazardous and nontoxic polymer. This reduces the risk of exposure to formaldehyde solution and vapor by the technician handling the material.

Claims (6)

1. A composition of matter for rapid neutralization of formaldehyde solution and vapor comprising:

a mixture of urea, acid and calcium chloride, whereby said mixture will rapidly neutralize formaldehyde solutions and vapor.

2. The composition of matter of claim 1 , wherein the mixture is applied to a matrix or medium and dried.

3. The composition of matter of claim 1 , wherein a varied type of acid can be combined with urea and calcium chloride.

4. The composition of matter of claim 1 , wherein calcium chloride is used as a formaldehyde neutralizing accelerant.

5. The composition of matter of claim 1 , wherein calcium chloride is used as a hydroscopic agent.
