Description
Technical Field
The invention relates to a processing method of talc-free sericite for cosmetics, belonging to the technical field of cosmetic raw materials.
Background
Talcum powder is used as filler, slipping agent and anticaking agent in cosmetics, and is commonly used in honey powder, talcum powder, powder cake, eye shadow, blush and face cream for increasing smooth touch of products. Some talc powders contain asbestos kerosenes, which are prone to lung irritation and risk carcinogenesis (lung, skin, ovarian). Asbestos is reported to be an internationally recognized primary carcinogen. In order to guarantee the safety of consumers, the detection standards of cosmetics issued by regulatory departments of various countries clearly require that asbestos cannot be detected in talcum powder used for cosmetics.
In order to further improve the safety of the products, talc-free products are being used in a step-by-step manner.
Because the wet-process mica powder is non-toxic and harmless, has no peculiar smell, has the characteristics of brightness and lubrication, no precipitate, easy dispersion and the like, a plurality of manufacturers at home and abroad are widely applied to fine chemical engineering and cosmetics, and about gorgeous color is added to the product. The wet mica has the advantages of smooth surface, pure texture, large diameter-thickness ratio, intact crystal face, large surface adhesion, etc.
In the prior art, in the wet grinding mica powder processing process, because the force applying mode and frequency of the crushing equipment to the materials are different, and the combination between subsequent processing technologies, the equipment selection, the optimization of operation parameters and other factors have great influence on the final quality of the mica powder, and the factors mainly include the thickness-diameter ratio, the particle size distribution, the generation and removal of micro colloidal particles, the roughness of the surface of a product wafer, the surface colloidal particle adhesion, the hydrolysis, adsorption and deposition of heavy metal salt and the like. The larger the radius-thickness ratio, the higher the specular reflectivity and the higher the brightness of the product. Therefore, it is an important direction to improve the aspect ratio of the product.
Disclosure of Invention
The invention aims to provide a processing method of sericite for cosmetics without talc, and the sericite powder processed by the method has high purity and extremely perfect flaky crystal form of particles, and is an excellent raw material for cosmetics.
The above purpose is realized by the following technical scheme:
a processing method of talc-free sericite for cosmetics comprises the following steps:
(1) selecting sericite ore, and crushing the sericite ore until the granularity is below 10 mm;
(2) washing the crushed sericite ore with acid and then washing with water to remove mud;
(3) grinding ore by using an edge runner mill, wherein the grinding ore concentration is 25-35% by mass;
(4) sorting by adopting a hydraulic cyclone;
(5) crushing by a jet mill, sieving by a high-frequency ultrasonic vibration sieve to ensure that the granularity reaches 12-25 mu m, performing filter pressing dehydration, and drying by hot air at 85-95 ℃.
The processing method of the talc-free sericite for cosmetics adopts a cone crusher for crushing in the step (1).
According to the processing method of the talc-free sericite for cosmetics, in the step (2), sulfamic acid and/or citric acid with the mass percentage concentration of 5-10% is adopted for acid washing.
The processing method of the talc-free sericite for cosmetics comprises the following steps of (5) grinding parameters of a jet mill: the water flow pressure of the jet mill is 15-25Mpa, and the impact target distance is 5-10 mm.
Has the advantages that:
1. the invention adopts sericite ore as raw material, sericite ore is natural mineral product, has extremely high chemical stability, belongs to complete inert substance, is safe, nontoxic and harmless, and is suitable for the requirements of cosmetics.
2. The invention adopts the process route of the edge runner mill, the hydraulic cyclone classification, the jet mill, the high-frequency ultrasonic vibration sieve and the hot air quick drying, the processed mica powder is fine and smooth, the average particle size (D50) of particles is different from several micrometers to one or twenty micrometers, and the particles do not contain large particles. The mica powder particle wafer is extremely thin, the ratio of the diameter to the thickness of the wafer (the diameter-thickness ratio) is as high as 80 to 120 times, and the covering power is extremely strong. The surface of the wafer is intact and smooth, so the powder has fine texture and smooth hand feeling. The crystal plate has strong pearl luster, especially when the grain size is appropriate, can be used for replacing or partially replacing expensive pearl pigment, and enhances the luster effect of the cosmetics.
3. The mica powder wafer processed by the invention can shield ultraviolet rays and infrared rays, so the mica powder wafer is an excellent cosmetic uvioresistant agent. The mica powder is pure natural, non-toxic and harmless, and has the advantages that the artificially synthesized organic uvioresistant agent does not have. Because the wafer is extremely thin and has extremely strong covering capability, a layer of ultraviolet-resistant protective agent and brightening agent which can not be seen by naked eyes can be formed on the surface of the skin only by a small amount of the products.
