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 air deodorizer and an antibacterial and antifungal agent.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
46 words
A PROCESS FOR PREPARING AN ORGANIC COMPOSITION WHICH COMPRISES CONTACTING THE PULPS OF GRAPEFRUIT WITH A NONTOXIC LIQUID, ALKYL POLYHYDRIC ALCOHOL OR A LOWER ALKYL ETHER THEREOF IN THE PRESENCE OF ULTRAVIOLET LIGHT TO FORM A REACTION PRODUCT, AND SEPARATING THIS PRODUCT FROM THE PULP RESIDUE.
Claim 2
Dependent Claim
46 words
A PROCESS FOR PREPARING AN ORGANIC COMPOSITION WHICH COMPRISES CONTACTING THE PULPS OF GRAPEFRUIT WITH A NONTOXIC LIQUID, ALKYL POLYHYDRIC ALCOHOL OR A LOWER ALKYL ETHER THEREOF IN THE PRESENCE OF ULTRAVIOLET LIGHT TO FORM A REACTION PRODUCT, AND SEPARATING THIS PRODUCT FROM THE PULP RESIDUE.
Claim 3
Dependent Claim
54 words
The process of claim 1 wherein the grapefruit pulp is contacted with an alcohol, selected from the group consisting of propylene glycol, glycerin, ethylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol, tetraethylene glycol, tripropylene glycol, polyethylene glycol, ethylene glycol n-butyl ether, ethylene glycol ethyl ether, diethylene glycol n-butyl ether, and diethylene glycol methyl ether.
Claim 4
Dependent Claim
31 words
The process of claim 2 wherein the pulp reactant comprises the inner pulp of fresh grapefruit having a low acid content as shown by a pH of about 2.5 to 5.
Claim 5
Dependent Claim
39 words
The process of claim 2 wherein the grapefruit pulp is contacted with propylene glycol or glycerin at a weight ratio of about 1:2, and the reaction is carried out at an elevated temperature in the presence of ultraviolet light.
Claim 6
Dependent Claim
14 words
The process of claim 1 wherein the grapefruit pulp is contacted with propylene glycol.
Claim 7
Dependent Claim
13 words
The process of claim 1 wherein the grapefruit pulp is contacted with glycerin.
Claim 8
Dependent Claim
64 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 in the presence of ultraviolet light at a temperature of about 90 to 140*F for a period of about 6 to 24 hours to form a reaction product.
Claim 9
Dependent Claim
64 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 in the presence of ultraviolet light at a temperature of about 90 to 140*F for a period of about 6 to 24 hours to form a reaction product.
Claim 10
Dependent Claim
43 words
An organic composition comprising the product obtained by contacting grapefruit pulp with a non-toxic liquid, alkyl polyhydric alcohol or a lower alkyl ether thereof in the presence of ultraviolet light, to form a reaction product, and separating this product from the pulp residue.
Claim 11
Dependent Claim
43 words
An organic composition comprising the product obtained by contacting grapefruit pulp with a non-toxic liquid, alkyl polyhydric alcohol or a lower alkyl ether thereof in the presence of ultraviolet light, to form a reaction product, and separating this product from the pulp residue.
Claim 12
Dependent Claim
49 words
The composition of claim 8 wherein the alcohol is selected from the group consisting of propylene glycol, glycerin, ethylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol, tetraethylene glycol, tripropylene glycol, polyethylene glycol, ethylene glycol n-butyl ether, ethylene glycol ethyl ether, diethylene glycol n-butyl ether, and diethylene glycol methyl ether.
Claim 13
Dependent Claim
39 words
An organic composition comprising the product obtained by contacting fresh grapefruit pulp having a pH of about 2.5 to 5.0 with a non-toxic liquid, alkyl polyhydric alcohol or a lower alkyl ether thereof in the presence of ultraviolet light.
Claim 14
Dependent Claim
39 words
An organic composition comprising the product obtained by contacting fresh grapefruit pulp having a pH of about 2.5 to 5.0 with a non-toxic liquid, alkyl polyhydric alcohol or a lower alkyl ether thereof in the presence of ultraviolet light.
