Abstract
The invention discloses preparation and application of a novel permanent agent glyceryl monmercaptoacetate. The glyceryl monmercaptoacetate disclosed by the invention is synthesized by taking a mercaptoacetic acid and glycerin as main raw materials through an esterification reaction method. The glyceryl monmercaptoacetate disclosed by the invention is obtained by esterifying and modifying the permanent agent mercaptoacetic acid; first purposes are the improvement of the moisture-holding performance of the permanent agent and the reduction of the damage of the permanent agent on the hair so that the hair subjected to the permanent maintains certain moisture without being sere; second purposes are the improvement of the boiling point of the permanent agent and the reduction of the volatility of the permanent agent, thereby reducing the odor of the permanent agent and improving the use performance of the permanent agent; and a third purpose is the reduction of the pH value of the permanent agent so that the permanent agent can be used under the conditions from weak acidity to neutrality.
Description
Technical field
The present invention relates to the preparation of a kind of novel agent for permanent hair waving-single Thiovanic acid glyceryl ester, this compound has good hair-waving and moisture-keeping functions, can be used as the humidity-preserving type agent for permanent hair waving and is applied in the hairdressing cosmetic.
Background technology
Beautifying hair is a kind of important cosmetic art, also is that people ask beautiful a kind of fashion most.The staple of hair is a Keratin sulfate; Account for 95%, Keratin sulfate is made up of amino acid, and wherein Gelucystine accounts for 14%; These amino acid are pressed long axis direction and are combined so that acid amides is strong in hair; Form peptide chain, and peptide chain is fixed through the disulfide linkage in the Gelucystine, ionic linkage and hydrogen bond formation key bridge each other, makes hair be certain shape.Hair-waving is exactly to open the key bridge, arrange again, fixedly hair style, constitute new key bridge again, make hair keep the hair style of solid shape.Utilize the method opened disulfide bond that heats and be aided with alkali lye, be called blanching; Utilize chemicals at normal temperatures the method for opened disulfide bond be called cold wave.Blanching is bigger to the damage of hair, not too uses at present.Popular is the cold wave method in the market.Employed chemical agent was called agent for permanent hair waving when cold wave was sent out.
Thiovanic acid is present the most frequently used agent for permanent hair waving functional component.The Thiovanic acid reductive action is more intense, has extraordinary hair-waving effect.But also there are some obvious defects in the Thiovanic acid agent for permanent hair waving.On the one hand, Thiovanic acid need be under the stronger condition of alkalescence (about about pH9.5) use the competence exertion effect of perming preferably, and alkaline condition is bigger to the damage of hair, after hair-waving, it is withered that hair seems, have in addition cause that scalp scratches where it itches.On the other hand, the Thiovanic acid boiling point is not high, and volatilization has unpleasant stink easily, makes troubles for the manufacturing and the use of hairdressing cosmetic.So the agent for permanent hair waving that low volatility was used, had to exploitation neutrality to slightly acidic scope has caused the very big interest of people.
Summary of the invention
The objective of the invention is to Thiovanic acid is carried out molecular structure alteration, carry out the synthetic single Thiovanic acid glyceryl ester of esterification with glycerine.
The synthetic starting material of using of single Thiovanic acid glyceryl ester of the present invention, by weight percentage, form by following material:
Another object of the present invention be with single Thiovanic acid glyceryl ester as the effective constituent of hairdressing cosmetic, make stable in properties, hair-waving is respond well and has the hairdressing cosmetic of good humidity-holding effect.
Compare with Thiovanic acid, have two hydroxyls in single Thiovanic acid glyceryl ester molecule of the present invention, have humidity-holding effect preferably, make the hair after the hair-waving can keep certain moisture, can improve the withered problem of hair; On the other hand, the boiling point of single Thiovanic acid glyceryl ester is more much higher than Thiovanic acid, and smell is very little, improves its use properties; The 3rd, single Thiovanic acid glyceryl ester just has good hair-waving effect in slightly acidic to neutral (pH4-7) scope, overcome the defective that Thiovanic acid must use under alkaline condition.Have a good application prospect.
Embodiment
Below come the present invention is further described through specific embodiment, but these embodiment are not limitations of the present invention just in order to explain.
One, Thiovanic acid glyceryl ester is synthetic
The preparation of embodiment 1 single Thiovanic acid glyceryl ester (sulfuric acid monohydrate hydrogen sodium is made catalyzer)
In the reactor drum that whisking appliance, TM, reflux condensing tube and water trap are housed, add Thiovanic acid, feed nitrogen, under agitation slowly add glycerine, band aqua and sulfuric acid monohydrate hydrogen sodium (making catalyzer).Slowly heat up, remain a constant speed and stir until beginning backflow.Insulated and stirred backflow 1-8h generates until no longer including water, and reaction finishes.Be cooled to room temperature then, underpressure distillation is removed and is obtained behind band aqua and the unreacted Thiovanic acid colourlessly to weak yellow liquid, is single Thiovanic acid glyceride compounds of the present invention.
The preparation (tosic acid is made catalyzer) of embodiment 2 single Thiovanic acid glyceryl ester
In the reactor drum that whisking appliance, TM, reflux condensing tube and water trap are housed, add Thiovanic acid, feed nitrogen, under agitation slowly add glycerine, band aqua and tosic acid (making catalyzer).Slowly heat up, remain a constant speed and stir until beginning backflow.Insulated and stirred backflow 1-8h generates until no longer including water, and reaction finishes.Be cooled to room temperature then, underpressure distillation is removed and is obtained behind band aqua and the unreacted Thiovanic acid colourlessly to weak yellow liquid, is single Thiovanic acid glyceride compounds of the present invention.
The preparation (thionamic acid is made catalyzer) of embodiment 3 single Thiovanic acid glyceryl ester
In the reactor drum that whisking appliance, TM, reflux condensing tube and water trap are housed, add Thiovanic acid, feed nitrogen, under agitation slowly add glycerine, band aqua and Sulphanilic Acid (making catalyzer).Slowly heat up, remain a constant speed and stir until beginning backflow.Insulated and stirred backflow 1-8h generates until no longer including water, and reaction finishes.Be cooled to room temperature then, underpressure distillation is removed and is obtained behind band aqua and the unreacted Thiovanic acid colourlessly to weak yellow liquid, is single Thiovanic acid glyceride compounds of the present invention.
