## 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

This invention relates to a composition for preserving animals as specimens. The composition is a three-in-one composition which is prepared by combining Formaldehyde Solution and Alcohol with particles made from Boric Acid, NaCl and Phenol, and it not only soaks and hardens animals entirely, but it also simplifies the process of production by avoiding the procedures of removing skeleton, muscle and internal organs from an animal carcass.

## Claims

### Claim 1

A composition for preserving non-living animal bodies comprising:
A) a particulate mixture of 100% boric acid, NaCl and phenol;
B) formaldehyde; and
C) alcohol
wherein the components A, B and C are present in a ratio of 1:1:1 by weight.

### Claim 2 (depends on 1)

A composition according to claim 1 wherein the formaldehyde is 35% by weight formaldehyde and the alcohol is 98% by weight alcohol.

### Claim 3 (depends on 1)

A composition according to claim 1 wherein the mixture of boric acid, NaCl and phenol is an approximately 1:15:3 by weight mixture.

### Claim 4 (depends on 1)

A composition according to claim 1 wherein the mixture of boric acid, NaCl and phenol is an approximately 1:15:3 by weight mixture.

### Claim 5

A method for preserving a non-living animal body, without removal of muscle, skeleton or internal organs, which comprises:
washing the animal body;
immersing the animal body in a vessel with a preservative composition comprising a particulate mixture of 100% boric acid, NaCl and phenol, formaldehyde and alcohol, wherein the boric acid, NaCl an phenol of said mixture are present in a ratio of 1:1:1 for approximately 36 hours for each kilogram of body weight;
removing the animal body from the preservative composition;
shaping the animal body; and
drying the animal body.

### Claim 6 (depends on 5)

A method according to claim 5 wherein the formaldehyde is 35% by weight formaldehyde and the alcohol is 98% by weight alcohol.

### Claim 7 (depends on 5)

A method according to claim 5 wherein the mixture of boric acid, NaCl and phenol is an approximately 1:15:3 by weight mixture.

### Claim 8 (depends on 6)

A method according to claim 6 wherein the mixture of boric acid, NaCl and phenol is an approximately 1:15:3 by weight mixture.

### Claim 9 (depends on 5)

A method according to claim 5 wherein the drying step takes at least 30 days.

### Claim 10 (depends on 9)

A method according to claim 9 wherein the drying step takes place in a shaded area.

### Claim 11

A composition for preserving non-living animal bodies comprising:
A) a particulate mixture of 100% boric acid, NaCl and phenol;
B) formaldehyde; and
C) alcohol,
wherein the components A, B and C are present in a ratio of 1:1:1, by weight and wherein the mixture of boric acid, NaCl and phenol is an approximately 1:15:3 by weight mixture.

### Claim 12 (depends on 11)

A composition according to claim 11 wherein the formaldehyde is 35% by weight formaldehyde and the alcohol is 98% by weight alcohol.

### Claim 13 (depends on 11)

A method for preserving a non-living animal body, without removal of muscle, skeleton or internal organs, which comprises:
washing the animal body;
immersing the animal body in a vessel with a preservative composition according to claim 11 for approximately 36 hours for each kilogram of body weight;
removing the animal body from the preservative composition;
shaping the animal body; and
drying the animal body.

### Claim 14 (depends on 12)

A method for preserving a non-living animal body, without removal of muscle, skeleton or internal organs, which comprises:
washing the animal body;
immersing the animal body in a vessel with a preservative composition according to claim 12 for approximately 36 hours for each kilogram of body weight;
removing the animal body from the preservative composition;
shaping the animal body; and
drying the animal body.

### Claim 15 (depends on 13)

A method according to claim 13 wherein the drying step takes at least 30 days.

### Claim 16 (depends on 14)

A method according to claim 14 wherein the drying step takes at least 30 days.

### Claim 17 (depends on 15)

A method according to claim 15 wherein the drying step takes place in a shaded area.

### Claim 18 (depends on 16)

A method according to claim 16 wherein the drying step takes place in a shaded area.
