Definitions
- This invention relates to the preparation of translucent soap, and particularly to a process for making hard milled soap bars which have a high degree of translucency.
- translucency can be substantially advanced by adding to the soap after saponification and before the soap is spray dried, small quantities of polyethylene glycol and propylene glycol.
- the manner in which these agents act to promote the quality of translucency is not precisely known but we believe that these agents have some effect on the crystal forming characteristics of the soap as it is being cooled during or after the spray drying step.
- translucency of the finished product is further enhanced by employing as the fatty acids to be saponified a special blend of the fatty acids obtained from tallow and coconut oil.
- Another factor found to contribute to the quality of translucency is that of heating the soap containing the above mentioned additives to a temperature which is substantially higher than usual prior to the subjection of the soap to spray drying.
- the first stage in the process may be carried out in the crutcher 10, a piece of equipment which is wellknown in the art.
- the fatty acids to be saponified may be charged into the crutcher. These acids may be a mixture of acids obtained from tallow and coconut oil in the proportion from about percent tallow acids to from 15 30 percent coconut acids. these percentages being based on the total weight of the acids. We have found that best results are obtained using about 80 percent tallow acids to 20 percent coconut acids.
- the alkali material is also charged into the crutcher. This may consist of from about 99 percent sodium hydroxide and from l 10 percent potassium hydroxide, the percentages being based on the total weight of the alkali. We have found that best results are obtained when using about percent sodium hydroxide and 5 percent potassium hydroxide.
- basic ingredients such as fatty acids, alkali and salts
- small amounts of other ingredients such as silicate of soda, glycerine and a clarifying agent also may be included as well as water in the adjustment of moisture.
- the moisture may be adjusted to about 18 percent i l or 2 percent, and on the basis of this amount of moisture salt is included in an amount of about 0.4 percent i 0.1 percent, these percentages being based on the total weight of the saponification mixture.
- Both the fatty acids and the alkali solution may preferably be preheated to about F., and after the acids have been neutralized steam may be opened on the jackets of the crutcher to maintain the neat soap at about F. 200F. Then after adjusting the neat soap for the desired alkalinity there is added to the soap the additives which we have found to be effective in the production of translucency.
- polyethylene glycol and propylene glycol are very effective in the production of translucency.
- Each of these glycols may be added in an amount of from 1 3 percent, based on the weight of the finished soap. Though not essential we perfer that the polyethylene glycol and propylene glycol be added in about the same amounts by weight. Upon addition of these additives mixing may be continued for a period such as 10 15 minutes to ensure uniform distribution of the glycols throughout the soap mass.
- polyethylene glycol and propylene glycol we may also use either polyethylene glycol or propylene glycol without the other if there is added along with the one of these glycols which is selected.
- the glycerine may suitably be in an amount of from I 3 percent based on the weight of the soap.
- the soap may then be passed directly to the spray drier 12, but for best results we pass the mixture first through a 'heat exchanger 11 to raise its temperature to a substantiallyhigher point than usual, suitably to at least about 290F., desirably about 300F.
- the hot soap mixture is passed into the spray drier 12 where it is dried and cooled preferably under vacuum, and as the soap is passed through the plodders 12a of the drier and formed into pellets its temperature may be at, for example, about 80 86F.
- the pellets may first be transferred to the amalgamator l3, and at this point perfume and coloring matter may be added.
- the perfume additives should not exceed 1.0 percent based on the weight of the soap, and preferably there should be added along with the perfume a quantity of polyethylene glycol and propylene glycol of the order of 0.3 0.9 percent of each of these additives, the percent being based on the weight of the soap, with best translucency being obtained when both polyethylene glycol and propylene glycol are added at about the same proportions.
- the pellets After being mixed for about 3 5 minutes in the amalgamator the pellets are passed to the first section 14 of the refining operation where the soap is recycled and then to the next section of the refining operation 15 where the soap is further refined and the temperature has been brought from about 75F. to about 98 100F.
- This refining operation produces a kind of shearing action which is beneficial to the soap.
- the refining and extrusion of the soap is best done under vacuum to prevent striations of the soap.
- the temperature of the soap during extrusion may be about 90 95F. and the slugs produced through the action of cutter 18 may be conditioned at ambient temperature for about an hour before being passed to the stamper 17 where the bars are stamped in the desired shape.
- the additives polyethylene glycol and propylene glycol be introduced after saponification and before the spray drying step. We find that if these additives are added before the saponification has been completed good translucency is not obtained.
- the fatty acids to be saponified be selected from mixed tallow and coconut fatty acids and in the proportions herein set forth. Also important is the selection of the alkali containing sodium hydroxide and potassium hydroxide in the proportions prescribed. Another feature of importance is the heating of the soap and additives mixture to a high value prior to the spray drying step in which the soap is cooled. Still another feature is the addition of further amounts of polyethylene glycol and propylene glycol additives with the perfume at the amalgamation stage.
- DIRECTIONS FOR TESTS Use a Color Master colorimeter instrument such as Model V to determine the percent reflectance. Standardization for reflectance measurement should be done first. Then, the method used in measuring translucency of soap involves cutting the bar to a thickness of one-half inch. Place the sample on the left-hand opening, turn the filter switch to the color reading which was selected in the standardization procedure. After adjusting the reflectance control to make the meter read zero, refine the adjustment by depressing the sensitivity switch. Record the reading on the reflectance dial at the percent reflectance.
- EXAMPLE I 5 (Control) A first soap stock was provided from 65 percent tallow fatty acids, 22 percent coconut fatty acids and 13 percent of transcisoleic acid in a 50/50 mixture. 50- dium chloride at 0.6 percent was added to the neat soap. The total batch of fatty acids was neutralized with 100 percent NaOH. No additives were added to the neat soap. The soap was processed into pellets. A mechanical work was put into the soap pellets and raised the temperature to 100 l05F. The translucency of the pellets appeared not to be substantially improved.
- EXAMPLE ll (Control) A 75/25 tallow/coconut fatty acid blend was neutralized with 100 percent NaOH using regular tap water for the dilution of the caustic solution. Salt was added at 0.6 percent, pellet moisture from dryer was about 18 i 1 percent. Before the soap was dried, l percent glycerinc and 3 percent propylene glycol were added to the neat soap after neutralization was completed. The pellets were processed through the simplex refiner to put work into the soap by converting the mechanical energy into heat energy and to cause the rise of the pellets temperature from 85F. to 105 i 2F. Translucency of the pellets was not substantially improved.
- a soap stock was provided from 15 30 percent coconut fatty acids and 85 70 percent tallow fatty acids saponified with 95 percent NaOH and 5 percent KOH. Sodium chloride at 0.6 percent was added to each batch of soap made using the same process.
- the translucency reading was determined by the percent of light reflection on one-half inch thick bar of soap and is given in the following table:
- the /20 tallow/coconut fatty acid batch was repeated using percent NaOH and 10 percent KOH also having 0.6 percent NaCl.
- EXAMPLE V An 80/20 tallow/coconut fatty acid blend was neutralized with 95 percent NaOH and percent KOH using deionized water for dilution of the caustic. The salt content was lowered to 0.4 percent and the soap moisture was 17 18 percent.
- Additives of 50/50 mixture of polyethylene glycol and propylene glycol at 3 percent based on the finished soap were added to the neat soap.
- Citrus perfume at a 0.5 percent level was dissolved in an equal amount of 50/50 mixture of the above additives solution, in addition to a minor amount of Ext. D & C yellow No. 10, were added to the pellets and mixed for 3 minutes.
- the resulting bar showed a very good translucency with about percent light reflection reading.
- fatty acids consist essentially of from 85 70 percent tallow fatty acids and from l5 30 percent coconut fatty acids.
- said fatty acids consist essentially of from 70 percent tallow fatty acids and from 15 30 percent coconut fatty acids, said percentages being based on the total weight of the acids and wherein there is used in said saponification an alkali consisting essentially of sodium hydroxide in a proportion of from 99 percent and potassium hydroxide in a proportion of from 1 10 percent. said percentages being based on the total weight of said alkali. and wherein said soap containing said additives is heated to a temperature of at least 290F. before spray drying.
- a process as set forth in claim 1 which includes the step of adding to said soap after the drying step, a perfume composition in an amount up to L0 percent based on the total weight ofthe soap, said composition containing polyethylene glycol and propylene glycol each in an amount of from 0.3 0.9 percent based on the weight of said soap.
- said fatty acid consists essentially of about 80 percent tallow fatty acid and about 20 percent coconut fatty acid.
- alkali consists essentially of about percent sodium hydroxide and about 5 percent potassium hydroxide.
