preparation example Construction

[0021] A preparation method of modified attapulgite, comprising the steps of:

[0022] (1) Mix attapulgite and sodium hexametaphosphate aqueous solution, stir at 30-70°C at 1000-2000 rpm for 20-60min, stop stirring, let stand for 60-120min, discard the lower sediment, and draw out the upper suspension, Vacuum spray dry the above suspension at 80-100°C to obtain purified attapulgite; the mass ratio of attapulgite to sodium hexametaphosphate aqueous solution is 1: (15-30); the mass concentration of sodium hexametaphosphate aqueous solution is 0.5 -3.5wt%; sodium hexametaphosphate is added to purify attapulgite, and improve adsorption capacity and water retention performance;

[0023] (2) Stir and mix 100 parts by weight of the purified attapulgite, 4-8 parts by weight of D-glucuronic acid, and 1-3 parts by weight of caprylyl glycine at 60-90°C at 800-1500 rpm for 1- After 3 hours, dry at 80-100° C. to constant weight, grind, and pass through a 100-500 mesh sieve to obtain the m...

Embodiment 1

[0033] The preparation method of modified attapulgite:

[0034] (1) Mix attapulgite and water, stir at 50°C at 1500 rpm for 40 minutes, stop stirring, and after standing for 90 minutes, the upper layer is a suspension and the lower layer is a sediment; discard the lower layer of sediment, draw out the upper layer suspension, and put the above The suspension was vacuum spray-dried at 90°C to obtain purified attapulgite; the mass ratio of the attapulgite to water was 1:20;

[0035] (2) 100 parts by weight of the purified attapulgite, 6 parts by weight of D-glucuronic acid, and 2 parts by weight of caprylyl glycine were stirred and mixed at 70°C at 1000 rpm for 2 hours, and dried at 90°C to constant weight , ground, and passed through a 300-mesh sieve to obtain the modified attapulgite.

Embodiment 2

[0037] The preparation method of modified attapulgite:

[0038] (1) Mix attapulgite and 2wt% sodium hexametaphosphate aqueous solution, stir at 50°C at 1500 rpm for 40 minutes, stop stirring, and after standing for 90 minutes, the upper layer is a suspension and the lower layer is a sediment; discard the lower layer of sediment, extract The upper layer suspension is vacuum spray-dried at 90°C to obtain purified attapulgite; the mass ratio of the attapulgite to the 2wt% sodium hexametaphosphate aqueous solution is 1:20;

[0039] (2) 100 parts by weight of the purified attapulgite and 6 parts by weight of D-glucuronic acid were stirred and mixed at 70°C at 1000 rpm for 2 hours, dried at 90°C to constant weight, ground, and passed through a 300-mesh sieve , to obtain the modified attapulgite.

Abstract

The invention discloses a moisturizing cosmetic, a moisturizing mask and modified attapulgite. The moisturizing cosmetic is prepared from 0.2 to 10 weight percent of the modified attapulgite. The moisturizing mask is prepared from the following components in percentage by mass: 1 to 3 percent of glycerinum, 0.5 to 1.5 percent of 1, 3-propylene glycol, 0.2 to 0.8 percent of sodium hyaluronate, 5 to10 percent of modified attapulgite and the balance of water. The modified attapulgite is prepared by the following steps: performing mixing on attapulgite and a sodium hexametaphosphate aqueous solution, performing centrifuging, and carrying out spray drying; and performing mixing on the purified attapulgite, D-glucuronic acid and capryloyl glycine, and performing drying to constant weight. The modified attapulgite prepared by the invention has high adsorption capacity and water retention capacity and excellent antibacterial property, and is particularly suitable for being applied to cosmetics. The moisturizing cosmetic prepared by the invention is excellent in moisturizing performance. The moisturizing cosmetic provided by the invention can be a toner, a whitening lotion, a moisturizingcream, a facial mask, a body lotion, a body lotion and the like.

Description

technical field [0001] The invention relates to a moisturizing cosmetic, a moisturizing mask and a modified attapulgite. Background technique [0002] Attapulgite clay refers to a clay mineral whose main component is attapulgite. Attapulgite is a crystalline hydrated magnesium aluminum silicate mineral with a unique layer chain structure. There is a lattice replacement in its structure, and the help crystal contains a variable amount of Na+, Ca2+, Fe3+, Al3+. It is needle-like, fibrous or fibrous aggregates. Attapulgite has good colloidal properties such as unique dispersion, high temperature resistance, salt and alkali resistance, and high adsorption and decolorization ability. And has a certain plasticity and cohesion. [0003] Attapulgite clay has been widely used in petroleum, chemical industry, building materials, papermaking, medicine, agriculture and other fields due to its special physical and chemical properties and technological performance. The largest domesti...
