Abstract

Abstract A process for producing a multi-use cleansing agent basically harmless to human skin from d-Limonene, a natural citrus peel oil derivative. The d-Limonene extract, having the basic formula C10H16 is high in citric acid, carbon, and isopropyl compounds and exhibits similarities in organic structure to turpentine, dipentine compounds. The d-Limonene is mixed with a liquid detergent containing ionic and anionic surfactants in a ratio of two parts detergent to one part d-Limonene. To this mixture is added a fifty (50%) percent mixture of bicarbonate of soda and slaked lime solution in a ratio of three parts soda/lime solution to one part d-Limonene to serve as a buffer for the high acid content of the d-Limonene. Water is then added under pressure in a ratio of three parts water to one part of the total mixture to create turbulence and a complete mixing by surface aeration. This mixture is then allowed to settle out into a top emulsified cream layer and a lower clear liquid layer containing the buffered d-Limonene. The clear liquid layer is decanted off to be used as the cleansing solution. Liquid ammonia may then be added to the clear solution as a drying agent in a ratio of three parts ammonia to one part clear liquid layer.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
A process for producing a d-Limonene cleaning agent, which comprises the following steps: a. providing d-Limonene compound; b. blending said compound with a 2:1 to 3:1 ratio of a liquid detergent selected from anionic and ionic surfactants and mixtures thereof; c. agitating said blended mixture; d. adding a mixture of bicarbonate of soda and slaked lime solution in a range of 2:1 to 3:1 by volume during the agitation of said mixture; e. mixing said agitated mixture with pressurized water at a ratio of 3:1 of water to d-Limonene mixture; f. allowing said hydrated mixture to separate into a top emulsified layer and a bottom clear liquid layer; and g. decanting said clear liquid layer for use as said cleaning agent.
Claim 2
Dependent Claim 121 words
A process for producing a d-Limonene cleaning agent, which comprises the following steps: a. providing d-Limonene compound; b. blending said compound with a 2:1 to 3:1 ratio of a liquid detergent selected from anionic and ionic surfactants and mixtures thereof; c. agitating said blended mixture; d. adding a mixture of bicarbonate of soda and slaked lime solution in a range of 2:1 to 3:1 by volume during the agitation of said mixture; e. mixing said agitated mixture with pressurized water at a ratio of 3:1 of water to d-Limonene mixture; f. allowing said hydrated mixture to separate into a top emulsified layer and a bottom clear liquid layer; and g. decanting said clear liquid layer for use as said cleaning agent.
Claim 3
Dependent Claim 23 words
The process of claim 1, wherein the water added to the agitated mixture is added under pressure for creating turbulence with said mixture.
Claim 4
Dependent Claim 22 words
The process of claim 1, wherein the portion of liquid detergent does not exceed a three-to-one ratio of detergent to d-Limonene extract.
Claim 5
Dependent Claim 27 words
The process of claim 1, wherein said bicarbonate of soda and slaked lime solution additives serve as a buffer for neutralizing the d-Limonene acids within the mixture.
Claim 6
Dependent Claim 38 words
The process of claim 1, further comprising the addition of ammonia to said clear liquid layer for use as a drying agent in a range of 2:1 to 3:1 by volume of ammonia to said clear liquid layer.
Claim 7
Dependent Claim 130 words
A process for producing a d-Limonene cleaning agent, comprising the following steps: a. providing d-Limonene compound; b. blending said d-Limonene compound with a 2:1 ratio of liquid detergent containing a mixture of ionic and anionic surfactants; c. agitating said blended mixture; d. adding a fifty (50%) percent mixture of bicarbonate of soda and slaked lime solution in a ratio of 3:1 by volume of said soda/lime solution to said d-Limonene during said agitation of said blended mixture; e. mixing said blended mixture wth pressurized water at a ratio of 3:1 by volume of water to said blended mixture; f. allowing said hydrated mixture to separate into a top emulsified cream layer and a bottom clear liquid layer; and g. decanting said clear liquid layer for use as said cleaning agent.
Claim 8
Dependent Claim 130 words
A process for producing a d-Limonene cleaning agent, comprising the following steps: a. providing d-Limonene compound; b. blending said d-Limonene compound with a 2:1 ratio of liquid detergent containing a mixture of ionic and anionic surfactants; c. agitating said blended mixture; d. adding a fifty (50%) percent mixture of bicarbonate of soda and slaked lime solution in a ratio of 3:1 by volume of said soda/lime solution to said d-Limonene during said agitation of said blended mixture; e. mixing said blended mixture wth pressurized water at a ratio of 3:1 by volume of water to said blended mixture; f. allowing said hydrated mixture to separate into a top emulsified cream layer and a bottom clear liquid layer; and g. decanting said clear liquid layer for use as said cleaning agent.
Claim 9
Dependent Claim 36 words
The process of claim 6, further comprising the addition of liquid ammonia to said clear liquid layer in a ratio of 3:1 by volume of ammonia to said clear liquid layer for use as drying agent.
