Abstract

ABSTRACT

The present invention provides a method of manufact-uring soap comprising the steps combining a first mixture of lye, soft water, fat and javel water with a second mixture of vinegar, soft water and sodium bicarbonate, adding to the thereby obtained combination carbolic acid, and a quantity of soft boiled water, and evaporating from the thereby obtained soap emulsion a desired quality of water to obtain a soap.

Description

The present invention relates to the field of soap making, and discloses improvements in the art of soap ma~ing, and the soap produced thereby.

Soap making, which may briefly but accurately be defined as the saponifica-tion of a long chain fatty acid in a alkaline milieu, has been practiced for a long time. In particular, a method of manufacturing soap is disclosed in Canadian Patent No.
197,057, issued February 10, 1920 to ~. Landry. Landry discloses a soap composed of grease, soda, sodium carbonate, bicarbonate of soda, olive oil, water and salt. In the quantities described by Landry, however, an unacceptably salty soap is obtained.
~urthermore, Landry discloses no method of eliminating impurities in the soap making process.

In Canadian Pa-tent No. 1,091,126, issued December 9, 1980 to Duff et al, a method of neutralizing soap solutions during manufacture, by the addition of an acid to the soap i5 shown.
This method, however, is heavily reliant on expensive equipment for its application. The need for expensive equipment in the alkaline neutralization process is substantially eliminated in -the present invention.

The object of the present invention is to overcome the above disadvantages, and provide an inexpensive method of manufacturing a soap from recyclable waste.

Accordingly, the present inventlon relates to (a) a method of manufacturing soap comprising the s-teps of preparing a first mix-ture of substantially one part by weight javel water, two and one half parts by weight lye, ten parts by weight soft water and ten parts by weight fat, (b) prepariny a second mixture of substantially ten parts by weight, relative to the javel water added to said Eirst mixture, of a three to one solution of soft water and vinega.r, and one part by weigh-t, relative -to the javel water added to said Eirst mixture, oE sodium bicarbonate, (c) combining the said -Eirst and second mixtures, and adding thereto substantially one-fourth par-t by weight, relative to the javel water added to said first mixture, of carbolic acid and substantially twenty parts by weight, relative to the javel water added to said first mixture, of soft water, to obtain a soap emulsion; and (d) drying said emulsion at moderate temperatures for at least two weeks to obtain a soap.

The presen-t invention is illustrated by the following examples:

~xample 1 In a large vessel, 20 oz. o~ lye flakes ~ere mixed with one gallon of cold soft water, 1 cup (8 oz.) of Javex~ and 10 pounds of fat, which had been re-cycled from a Erench-fry maker, and sterilized by extended boiling.

4~

In a separate vessel, 40 oz~ of vinegar were mixed with 120 oz~ of sof~ sterilized water and 8 oz. of sodium bicarbonate.
This solution was then adcled -to the resultant admixture, and 2 gallons of soft, sterilized water added afterwards.

The entire mixture was well mixed, and then allowed to dry for two weeks.

The yielcl of the above process was approximately 50 lb.
of a solid soap, substantiall~ free of any bacteriological or mineral impurities, with a desirable sel-buffering property. Due to the exclusive use of soft, sterilized water in the present process, t~e soap obtained is relatively ree of any impurities.
The soap is also very inexpensively produced.

Example 2 The same process as that shown in Example l was performed; however, the quantity of water added was doubled. The soap was dried only to a viscous liquid consistency. The resultant product was a shampoo with the desirable products listed above for the soap of Example l.

Example 3 One quart of the soap of Example 2 was combined with l pound of shortening, l~ pound of bees' wax, 80 o~O of an aqueous solution of vinegar and sodium bicarbonate, and one quart of soEt boiled water.

The thereby ob-tained mixtllre was thorough:Ly boiled to remove impurities. An effec-tive skin moisturizing lo-tion was thereby obtained.

Example 4 The 8 oz. oE soap of Example 2 were mixed with 1 pound oE
shortening, 1/3 pound bees' wax, one cup of oil, one cup of sublimed sulphur and 20 drops of carbolic acid. This mixture was thoroughly blended.

The resultant mixture was found to be an effective skin ointment, useful in the treatment of minor skin irritations.

Claims

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method of manufacturing soap comprising the steps of a) preparing a first mixture of substantially one part by weight javel water, two and one half parts by weight lye, ten parts by weight soft water and ten parts by weight fat;

b) preparing a second mixture of substantially ten parts by weight, relative to the javel water added to said first mixture, of a three to one solution of soft water and vinegar, and one part by weight, relative to the javel water added to said first mixture, of sodium bicarbonate;

c) combining the said first and second mixtures, and adding thereto substantially one-fourth part by weight, relative to the javel water added to said first mixture, of carbolic acid and substantially twenty parts by weight, relative to the javel water added to said first mixture, of soft water, to obtain a soap emulsion; and d) drying said emulsion at moderate temperatures for at least two weeks to obtain a soap.

2. A method as claimed in Claim 1 wherein the said fat is sterilized, recycled frying oil.

3. A method as claimed in Claim 1 wherein the quantity of soft water added in step (c) is substantially 40 parts by weight relative to the javel water added to said first mixture, to thereby obtain a soap of viscous character.

4. A method as claimed in Claim 3 wherein the said fat is sterilized recycled frying oil.

5. A method as claimed in Claim 4, further comprising the steps of adding to the soap shortening, bees wax, vinegar, sodium bicarbonate, and soft, boiled water, to obtain a skin lotion.

6. A method as claimed in Claim 4, further comprising the step of adding to the soap shortening, bees wax, vegetable oil, sublimed sulphur and carbolic acid to obtain a skin ointment.

7. A soap when made in accordance with the method of Claims 1 or 2.

8. A soap when made in accordance with the method of Claim 3 or Claim 4.

9. A lotion made in accordance with Claim 5.
