Abstract

The invention discloses sepiolite talcum powder and a preparation method thereof, wherein the raw materials of sepiolite powder, borneol, common cnidium fruit, castor-oil plant, ficus tikoua, pseudo-ginseng, oleamide and the like are added into a ball mill for wet ball milling, then are dried and ground to obtain the sepiolite talcum powder.

Description

sepiolite talcum powder and preparation method thereof

Technical Field

The invention relates to sepiolite talcum powder and a preparation method thereof, belonging to the field of skin care products.

Background

Miliaria is a common superficial and inflammatory skin disease in summer or in hot environments. Under the high-temperature muggy environment, a large amount of sweat is not easy to evaporate, so that the cuticle is soaked and swollen, and sweat gland ducts are narrowed or blocked, so that the sweat is retained and seeps out of surrounding tissues to form papules, blisters or pustules which are better developed at the plica parts.

The talcum powder has the functions of absorbing sweat, removing dampness, stopping miliaria and relieving itching, but the talcum powder on the market at present generally contains talcum powder and other chemical additives, so that the talcum powder has fixed irritation to human skin, the traditional talcum powder mainly takes the talcum powder as a raw material, also takes a leading position on the market, and is a mainstream product, the talcum powder is low in price and easy to push , the main component of the talcum powder is magnesium silicate, the talcum powder has good lubricity due to a unique hexagonal flaky crystal structure, the addition amount of the talcum powder in the talcum powder is quite high, the talcum powder is formed by crushing natural ores, natural impurities of the talcum powder are asbestos, the asbestos is carcinogenic substances, and the health of a human body is seriously harmed.

The sepiolite powder has a special porous structure, the average pore diameter of micropores is 20nm, the sepiolite powder is in capillary distribution, the sepiolite powder determines that the sepiolite powder has strong adsorbability and can also be used as a catalyst carrier, the sepiolite has very outstanding adsorbability and has greater adsorbability on organic solutions such as butane, benzene and methanol and harmful metal ions, for example, a tobacco pipe adsorbing material made of the sepiolite has little adsorption of furan polar substances with fragrance in cigarette adsorption, high adsorbability on strong-polarity toxic nitrile substances and high filtering efficiency on carcinogenic fused ring aromatic hydrocarbons, and can obviously reduce tar content, the sepiolite powder has quantitative silicon hydroxyl groups on the surface, the sepiolite powder has higher length-diameter ratio and large specific surface area, and the theoretical value of the specific surface area is as high as 900m²·g^-1And the thermal stability is good.

The research of preparing the sepiolite talcum powder by taking sepiolite powder, borneol, fructus cnidii, castor oil plant, fructus corni, pseudo-ginseng and oleamide as raw materials and adopting a wet ball milling process is not reported at present, the borneol is traditional Chinese medicines with the functions of clearing heat, removing toxicity, relieving itching and inducing resuscitation, the fructus cnidii is traditional Chinese medicines with the functions of killing insects and relieving itching, the castor oil plant is traditional Chinese medicines with the functions of detumescence and relieving itching, the fructus corni is traditional Chinese medicines with the functions of detumescence, detoxification, promoting blood circulation and dispelling wind, the pseudo-ginseng is traditional Chinese medicines with the functions of removing blood stasis, stopping bleeding, detumescence and relieving pain, and the oleamide has no toxicity and excellent lubricity and can be used as.

Disclosure of Invention

The invention aims to provide kinds of sepiolite talcum powder and a preparation method thereof, and the sepiolite talcum powder prepared by the method has good miliaria-relieving, itching-relieving and sweat-absorbing functions.

In order to achieve the purpose, the invention adopts the following technical scheme:

A method for preparing the sepiolite talcum powder, which is characterized by comprising the following steps:

, weighing the following raw materials, namely sepiolite powder, borneol, fructus cnidii, castor oil, fructus kochiae, pseudo-ginseng, oleamide and ethanol in mass ratio of 100 to (1-5) to (2-6) to (1-3) to (1-5) to (1-4) to (1-5) to (100-150), and adding the weighed raw materials into a ball mill to perform wet grinding for 1-2 hours to obtain paste;

and step two, drying the paste obtained in the step to remove ethanol, and then adding the paste into a ball mill for dry grinding to obtain the sepiolite talcum powder.

Compared with the prior art, the invention has the following advantages:

(1) when the sepiolite talcum powder is prepared, a compound preparation is compounded by using the traditional Chinese medicines of borneol, common cnidium fruit, castor oil plant, fructus corni and pseudo-ginseng, so that the prepared sepiolite talcum powder has good miliaria-relieving and itching-relieving functions;

(2) when the sepiolite talcum powder is prepared, the porous property, the large specific surface area and hydroxyl groups with certain quantity on the surface of the sepiolite talcum powder are utilized to adsorb and slowly release the effective medicinal components in borneol, common cnidium fruit, castor oil plant, ficus tikoua and pseudo-ginseng, so that the prepared sepiolite talcum powder has good lasting miliaria-relieving and itching-relieving functions;

(3) when the sepiolite talcum powder is prepared, the prepared sepiolite talcum powder has a good sweat absorbing function by utilizing the porosity, large specific surface area and -defined hydroxyl groups on the surface of the sepiolite talcum powder;

(4) when the sepiolite talcum powder is prepared, ethanol is added into the raw materials for wet ball milling, and the ethanol is used for dissolving and leaching the effective medicinal components in the borneol, the fructus cnidii, the castor oil plant, the fructus corni and the pseudo-ginseng, so that the effective medicinal components are well adsorbed and slowly released by the sepiolite powder, and the prepared sepiolite talcum powder has good persistence of miliaria-stopping and itching-relieving functions;

(5) when the sepiolite talcum powder is prepared by the method, the prepared sepiolite talcum powder has good smoothness by utilizing the oleamide in the raw materials.

Detailed Description

The technical solution of the present invention is further described in step by the following specific examples.

Example 1
