Abstract
Abstract Grapefruit pulp is reacted with an alcohol or ketone, preferably a polyhydric alcohol such as propylene glycol or glycerin, in the presence of a free radical initiator such as ultraviolet light to produce a stable reaction product useful as an ingredient in various cosmetic products and for other purposes. The product is also highly effective as an antibacterial and antifungal agent.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
32 words
A process for preparing an organic composition which comprises contacting the pulps of grapefruit with a non-toxic polyhydric alcohol to form a reaction product and separating this product from the pulp residue.
Claim 2
Dependent Claim
32 words
A process for preparing an organic composition which comprises contacting the pulps of grapefruit with a non-toxic polyhydric alcohol to form a reaction product and separating this product from the pulp residue.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein the polyhydric alcohol is selected from the group consisting of propylene glycol and glycerin.
Claim 4
Dependent Claim
24 words
The process of claim 2 wherein the grapefruit pulp is the inner pulp of fresh grapefruit having a pH of about 2.5 to 5.0.
Claim 5
Dependent Claim
32 words
The process of claim 2 wherein the grapefruit pulp is contacted with the polyhydric alcohol at a weight ratio of about 1:2, and the reaction is carried out at an elevated temperature.
Claim 6
Dependent Claim
14 words

Claim 7
Dependent Claim
13 words
The process of claim 1 wherein the grapefruit pulp is contacted with glycerin.
Claim 8
Dependent Claim
67 words
A process for forming an organic composition which comprises contacting fresh grapefruit pulp having a low acid content, as shown by a pH of about 2.5 to 5.0, with an excess of propylene glycol or glycerin at a temperature of about 90° to 140° F. for a period of about 6 to 24 hours to form a reaction product and separating the product from the pulp residue.
Claim 9
Dependent Claim
67 words
A process for forming an organic composition which comprises contacting fresh grapefruit pulp having a low acid content, as shown by a pH of about 2.5 to 5.0, with an excess of propylene glycol or glycerin at a temperature of about 90° to 140° F. for a period of about 6 to 24 hours to form a reaction product and separating the product from the pulp residue.
Claim 10
Dependent Claim
29 words
An organic composition comprising the product obtained by contacting grapefruit pulp with a non-toxic polyhydric alcohol to form a reaction product, and separating this product from the pulp residue.
Claim 11
Dependent Claim
29 words
An organic composition comprising the product obtained by contacting grapefruit pulp with a non-toxic polyhydric alcohol to form a reaction product, and separating this product from the pulp residue.
Claim 12
Dependent Claim
14 words
The composition of claim 8 wherein the polyhydric alcohol is propylene glycol or glycerin.
Claim 13
Dependent Claim
21 words
The composition of claim 8 wherein the grapefruit pulp is fresh grapefruit pulp having a pH of about 2.5 to 5.0.
Claim 14
Dependent Claim
12 words

Claim 15
Dependent Claim
35 words
The composition of claim 11 wherein an excess of propylene glycol is contacted with the grapefruit pulp at a temperature of about 90° to 140° F. for a period of about 6 to 24 hours.
Claim 16
Dependent Claim
23 words
The composition of claim 8 wherein the polyhydric alcohol is contacted with the grapefruit pulp in the presence of a free radical initiator.
