## CPC

- A01N 1/00: Preservation of bodies of humans or animals, or parts thereof
- A01N: PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toiletry purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS

## Abstract

An improved non-formaldehyde-based preservative fluid is provided, comprising deionized water, a food-grade preservative, selected from the group consisting of sodium erythorbate and stereoisomers of ascorbic acid; and a humectant, selected from the group consisting of glycerin, glycerol, propylene glycol, glyceryl triacetate, and similar hygroscopic materials. Optional lanolin, dyes, or fragrances may be added as desired. Use of the improved fluid results in a more life-like appearance of the body, better tissue preservation, low odor, and a safer and environmentally sound alternative to conventional preservation fluids.

## Claims

### Claim 1

An improved tissue preservative fluid, comprising:
(a) deionized water in an amount of 5% to 95%;
(b) a food-grade preservative, selected from the group consisting of sodium erythorbate and stereoisomers of ascorbic acid, in an amount of 0.5% to 10%; and
(c) a humectant, selected from the group consisting of glycerin, glycerol, propylene glycol, glyceryl triacetate, and similar hygroscopic materials, in an amount of 5% to 75%.

### Claim 2 (depends on 1)

The fluid of claim 1, further including a lanolin material in an amount of 0.01% to 1%.

### Claim 3 (depends on 1)
