Abstract
The present invention relates to a synthetic laundry detergent bar composition containing soap including bitter salt and having improved physical properties. The present invention also relates to a process for manufacturing the compositions.
Description
The present invention relates to contain the laundry detergent composition of soap, said composition comprises having the sal epsom that improves physical properties.This paper also comprises the such method for compositions of preparation.
In the society that mechanical washing machine is not popularized, the laundry detergent bar that contains synthetic organic surface active agent and clean washing assistant is used to the washing of clothes.Technical development in the laundry detergent bar field has related to the soap bar that clothes is washed in preparation effectively; This soap bar has satisfied bubbling character in hot water and cold water and hard water and soft water; This soap bar has the satisfied use rate of wear, hardness, weather resistance and sensation; This soap bar has low smearing property; Have pleasant smell and outward appearance with this soap bar.The method of making laundry detergent bar in the art also is known.The prior art of soap bar and the manufacturing laundry soap bar method of openly doing washing comprises: the United States Patent (USP) 3178370 (0kenfuss) of promulgation on April 13 nineteen sixty-five; Philippine patents 13778 (Anderson) with promulgation on September 23rd, 1980.
In soap bar physical properties side and a common issue be the soap bar crystallization.Without being limited by theory, crystallization comprises the salt crust that formation is sand-like, forms little solid and forms transparent crystallization on the soap bar surface.After soap bar is aging out-of-date, crystallization occurs, wherein form and cause the soap bar cracking on the soap bar surface.
Sal epsom has been used as structural agent, and with improvement hardness, and the siccative/absorbent material that is used as in the detergent for washing clothes (is seen disclosed BR8705030 on May 24th, 1988; On September 19th, 1989 disclosed BR8900268; With disclosed PH28991 on January 31 nineteen ninety-five; On December 3rd, 1991 disclosed US5069825).Also referring to disclosed US2988511 on June 13rd, 1961, and CN1034219.
Therefore the clothing detergent bar composition of soaping that contains that has been found that the mixture that contains synthetic surfactant and soap and about 7% sal epsom of about 1-now also also makes consequential soap bar cracking minimum provide in the remarkable improvement aspect the physical properties by making soap bar crystallization minimum.

Other insoluble filler comprises mineral substance, for example, talcum, the mineral substance of the magnesium silicate of wilkinite and hydration, wherein with this silicate and other mineral substance, for example old parent rock such as rhombspar mix.
The soap bar physical properties
Laundry detergent bar of the present invention has level and smooth and uniform outward appearance.The adding of sal epsom helps to keep this outward appearance and the crystallization and the cracking that prevent on the soap bar surface.Crystallization generally is the white mass that occurs on the soap bar surface when aging and by the water-soluble inorganic salt that is present in this laundry soap bar, filler, soap, other component composition of synthetic surfactant and trace.Although do not wish to use one theory, it is believed that it mainly is into to cause in the environment owing to the mobile of moisture in soap bar with owing to it tends to overflow that crystalline forms.In this process, what bring into the moisture of process mainly is that water miscible but nonvolatile material and these electrodeposition substances are on the soap bar surface.Along with this process continues, the balance in soap bar is further upset, and the cohesive force of soap bar component weakens, and the cracking beginning develops on the soap bar surface.
The laundry soap bar keeps the stability experiment in its level and smooth and uniform at least 2 weeks of outward appearance, and this requirement of experiment will be exposed in the environment under low temperature (about 10-20 ℃) and the relative humidity (about 30-60%) less than the soap bar that encapsulates.If abundant encapsulation divides loss to prevent water, same soap bar so of the present invention keeps it level and smooth much longer with the no crystalline outward appearance time, even after being exposed to this soap bar under the temperature and humidity condition identical with the aforementioned stable experiment.Observed the time that soap bar of the present invention keeps its no crystalline outward appearance even also grew than 6 months.
With penetrometer measure and the soap bar hardness represented with 1/10mm in the scope of 35-50.This mensuration is to carry out after preconditioning is spent the night after aging 3 days and in the constant relative humidity environment of 26.7 ℃ constant temperature and 80%.Final bar composition contains and is low to moderate 5%-up to 30% moisture.In order to control hardness better, preferably, moisture content should be between 15-25%.Can measure moisture content by methods known in the art (its example is a Carl Fischer moisture titration method).
Additional clean component
