Embodiment 1

[0026] (1) Powder-filled hydrogel formula 1: 0.5 g of pearl powder (2000-3000 mesh in particle size), 0.3 g of sodium hydroxymethyl cellulose, and 10 g of deionized water.

[0027] (2) Powder-filled hydrogel formula 2: 0.5 g of pearl powder (particle size 2000-3000 mesh), 0.3 g of sodium hydroxymethyl cellulose, and 10 g of essence.

[0028] (3) Preparation of powder-filled hydrogel: according to the formula amount, the pearl powder is prepared with deionized water and essence as solvents to prepare the pearl powder suspension, and the formula amount of gelling factor sodium hydroxymethyl cellulose is added while stirring magnetically , and continue stirring for 1 hour. Then the hydrogel was ultrasonicated in an ultrasonic cleaner (40KHz) for 20 minutes to obtain a powder-filled hydrogel.

[0029] Stability test: Centrifuge the powder-filled hydrogel in a centrifuge for 10 minutes at a speed of 4000r / min, and observe the degree of stratification.

Embodiment 2

Abstract

The invention discloses powder-filled hydrogel. The powder-filled hydrogel is prepared from, by mass, 0.5 part of powder, 0.05-0.5 part of gelator and 5-20 parts of solvent. The powder is prepared from plant powder for cosmetics, pearl powder and inorganic particles for cosmetics. The gelator is obtained by mixing one or more of sodium polyacrylate, sodium carboxymethylcellulose, carboxymethyl cellulose sodium, polyacrylic acid copolymer, sodium alga acid and Carbomer. The gelator is free of toxicity, safe, low in price and free of pollution and facilitates the application and popularization of the gel product. The powder-filled hydrogel is high in stability, free of delamination, easy to store, easy to absorb and good in smear feeing and can be widely applied to the field of cosmetics.

Description

(1) Technical field [0001] The invention relates to a powder-filled hydrogel, in particular to a powder-filled hydrogel for cosmetics and its preparation and application. (2) Background technology [0002] Pearl powder and natural plant powder have excellent skin whitening effects, and have become more and more popular among consumers. Modern research shows that pearl powder has unique effects in improving human immunity, delaying aging, removing freckles, whitening, and supplementing calcium. "Pharmacopoeia of the People's Republic of China" and "Dictionary of Traditional Chinese Medicine" both specify that pearls have the effects of calming the nerves, calming convulsions, improving eyesight, detoxifying and promoting muscle growth. Whitening natural plant powders include rose powder, aloe powder, angelica powder, poria powder and so on. Rose powder is rich in amino acids, proteins, organic acids, vitamin C, etc. needed by the human body, and contains three rich and rare...
