Abstract
The present invention relates to preparation method of a crystal soap, which is formed by that disposable batch charging and disposable salting out are used, and a saponifying process is completed at temperature of 85 to 97 DEG C; a small amount of subsidiary material with high efficiency is added to the technology to carry out permeation crystallization in vacuum, full extraction technology is carried out by an extraction agent of mixed alcohol, harmful impurities in a soap are completely separated, and pure soap degree in the soap reaches up above 95%; casting technology is used for the solid forming of the soaps, vacuum sizing is carried out, and finally a transparent crystal soap is obtained. Sources of raw materials used by the method are wide, and quality is not strict, so cost is low. Because saponifying time is short, and thus, production period is greatly shortened. The obtained product has sound quality and high detersive power, and a byproduct of glycerol has large recovery quantity and good quality.
Description
The present invention relates to a kind of preparation method of soap, particularly relate to a kind of preparation method of crystallized soap.
As the soap of people's daily life requisite, the appearance of its product and production technique has a long history.Therefore, soapmaking technology is a kind of quite sophisticated conventional art.Produce the soap series products at present both at home and abroad, all adopt to feed intake gradually and repeatedly feed intake as its technologies such as perfumed soap, washing soap and produce soap base, its advantage is more complete than once finishing the saponified soap base.But shortcoming is: 1, must decide according to production technique and prescription when selecting raw material for use, rather than draft technology and prescription according to raw material properties, thereby raw material selected has limitation.2, saponification time is long, and about 76 hours, thus whole production technology is tediously long.3, gained byproduct glycerol amount is few shoddy.4, all contain the impurity (unsaponifiables) that is unfavorable for human body and fabric in its product to some extent.Simultaneously, for improving the hardness of soap, need outer filled (as diatomite, carclazyte etc.) all to be harmful to the person and fabric.And causing the content of genuine soap (sodium soap) to reduce, pure soap content is the highest to be no more than 85%.In washing soap, what pure soap content was the highest is 70%, and general only contains 45%, thereby washing effect is not good.
At existing problem in traditional soap preparing process, the inventor proposes a kind of brand-new soap preparing process, this technology is not to remove selected raw material according to technology and prescription, but remove selected technology and prescription according to raw material, therefore be not subjected to the restriction of any animal and plant grease and the oil that becomes sour, thereby enlarged raw material sources.This process using is disposable simultaneously feeds intake and finishes the saponified whole process, both saved manpower, shortened the production cycle significantly again, reduced cost widely, improved economic benefit, products obtained therefrom is the transparent crystals shape, and pure soap content is that current domestic and international various soap series products are incomparable up to more than 95%.
Crystallized soap preparation method of the present invention comprise raw material with acid-base neutralisation, saponification, saltout, soap base adds efficient auxiliary material infiltration crystallization, with technologies such as alcohol mixture extraction, casting, Vacuum shapings, its concrete steps are as follows:
Get, Vegetable oil lipoprotein is that raw material is in proportion through chemically examining definite iodine, after acid number and the saponification value, place melting kettle the heating under with acid-base neutralisation to pH8-9, left standstill hydrolysis then 4 hours, after levels impurity is removed in vacuum filtration, be transferred in the saponification still, under constant temperature alkaline saponification 3.5-4 hour, adding NaCl then saltoutd 40 minutes, separate lower floor to reclaim glycerol, in the soap base of upper strata, added auxiliary material vacuum infiltration crystallization 1.5 hours, again with alcohol mixture extraction 40-60 minute, after extraction liquid is limpid, behind vacuum suck filtered and recycled extraction agent, be molded into Vacuum shaping in the mould, get the transparence crystallized soap.
In the aforesaid method, described raw material is the mixture of animal tallow and vegetation fat.Animal tallow is butter, sheep oil, and vegetation fat is soya-bean oil, peanut oil, Viscotrol C, Oleum Cocois, rapeseed oil, palm-kernel oil, and the weight ratio of animal tallow and vegetation fat is 70-85: 15-30 usually, and the acid of fat is situated between and is the 1-50 valency.
In the aforesaid method, the composition of described auxiliary material and add-on are:
Composition is with respect to the % of soap base matter weight
Sodium lauryl sulphate 3-7
Carboxymethyl cellulose 0.3-0.5
Ethylenediamine tetraacetic acid (EDTA) 0.1-0.2
Boric acid 1-2
Oxalic acid 0.3-0.5
Tripoly phosphate sodium STPP 3-7
Water glass 3-25
In the aforesaid method, described alcohol mixture extraction agent is a kind of a kind of other solvent compositions that add in butanols, acetone, ethyl acetate, pentyl acetate, the tetracol phenixin in first, the ethanol, first, ethanol is 99: 1 with the weight ratio of other solvents, and consumption is 30% of a soap base weight during extraction.
In the aforesaid method, described neutralization, saponification, salt eutectoid temperature are 85-97 ℃, and extraction temperature is 78 ℃, and it is 50 ℃ that Vacuum shaping reclaims the extraction agent temperature.
In the aforesaid method, described vacuum filtration, vacuum are crossed the infiltration crystallization, and the pressure during Vacuum shaping is 0.1Mpa.
In the aforesaid method, the material of described melting kettle, saponification still is a stainless steel, and described material of watering mold is an aluminum magnesium alloy.
Method of the present invention is compared with the soapmaking method of routine, has following remarkable advantage:
1, the raw material of method of the present invention is not subjected to any animal and plant grease and the restriction of the oil that becomes sour, and can select concrete technology and prescription according to the difference of raw material, thereby raw material sources is extensive, and is cheap.
2, the inventive method is produced the technology of soap base, adopts best saponification temperature 85-97 ℃, and disposablely feeds intake and finish the saponification process.Both save manpower and materials, significantly shortened the production cycle again.
3, the inventive method, owing to be disposable feeding intake, disposable saltouing, the byproduct glycerol amount of gained is of fine quality greatly.
4, the inventive method is assisted material vacuum infiltration crystallization process because employing adds trace, thereby has guaranteed the practical function of crystallized soap product.
5, method of the present invention will all exclude human body and fabric harmful factors (unsaponifiables, impurity) in soap base and the auxiliary material because of taking full extraction process.The genuine soap degree reaches more than 95% in the soap thereby make, and is that current domestic and international various soap series products are incomparable.
6, the inventive method is owing to taked the solid forming of full extraction process (promptly dissolving extract technology) so soap to adopt casting process, and Vacuum shaping is with the extraction agent recycling.And conventional soapmaking method does not all have this technology.
The following examples will further specify method of the present invention,
