Embodiment 1

[0039] A kind of cellulose nano whisker antibacterial and moisturizing cream type mask, its preparation process is as follows:

[0040] (1) 5 g of microcrystalline cellulose, pretreated with 1% acetic acid at 40°C for 60 min, washed with deionized water until neutral, and then treated with 10 IU of cellulase (Novozymes company model is Cellulase of D) was treated at 60°C for 12 h, then heated at 80°C for 10 min to inactivate the enzyme, and then homogenized at 20,000 psi for 20 times to obtain cellulose with a diameter of 5 nm and a length of 200 nm nano whiskers.

[0041] (2) The cellulose nanowhiskers, chitosan, other functional ingredients and deionized water were mixed according to a certain mass ratio at 40°C at 1000 r / min for 10 min, and then mixed at room temperature at 5000 r / min Emulsified for 30 minutes, and finally degassed at -0.1MPa for 24 hours and then sealed to prepare the cellulose nano whisker antibacterial and moisturizing cream mask. Among them, the mass...

Embodiment 2

[0044] A kind of cellulose nano whisker antibacterial and moisturizing cream type mask, its preparation process is as follows:

[0045] (1) 5g microcrystalline cellulose, be that 2% citric acid aqueous solution is pretreated at 70 ℃ for 10min through mass fraction, wash with deionized water to neutrality, then use the cellulase of 100IU (Novozymes company model is Cellulase of D) was treated at 30°C for 36h, then heated at 80°C for 10min to inactivate the enzyme, and then homogenized 5 times under a pressure of 30,000psi to obtain cellulose nanowhiskers with a diameter of 40nm and a length of 600nm.

[0046] (2) The cellulose nano whiskers, chitosan, other functional ingredients and deionized water were mixed according to a certain mass ratio at 500r / min at 90°C for 30min, and then 10000r / min at room temperature for After 10 minutes of emulsification, it was degassed at -0.1 MPa for 5 hours and then sealed to prepare the cellulose nano whisker antibacterial and moisturizing c...

Embodiment 3

[0049] A kind of cellulose nano whisker antibacterial and moisturizing cream type mask, its preparation process is as follows:

[0050] (1) 5g of microcrystalline cellulose, pretreated with 5% hydrochloric acid at 40° C. for 30 min, washed to neutrality with deionized water, then 50 IU of cellulase (Novozymes company model is The cellulase of D) was treated at 50°C for 2h, then heated at 80°C for 10min to inactivate the enzyme, and then homogenized 10 times under a pressure of 20,000psi to obtain cellulose nanowhiskers with a diameter of 10nm and a length of 500nm.

[0051] (2) The cellulose nano whiskers, chitosan, other functional components and deionized water were mixed according to a certain mass ratio at 60°C at 100r / min for 60min, and then emulsified at room temperature for 5min at 15000r / min. Finally, it was degassed at -0.1MPa for 1 hour and then sealed to prepare the cellulose nano whisker antibacterial and moisturizing cream mask. Among them, the mass ratio of cel...

Abstract

The invention discloses a cellulose nano whisker antibacterial and moisturizing cream type mask as well as a preparation method and application thereof. The cellulose nano whisker antibacterial and moisturizing cream type mask is prepared from the following components in percentage by mass: 1-20% of cellulose nanocrystal, 0.5-3% of chitosan, 1-5% of polyvinyl alcohol, 0.1-2% of sodium alginate, 0.1-2% of propylene glycol, 1-3% of glycerin, 0.1-2% of silicon emulsion, 0.1-1% of aloe extract, 0.5-2% of ethanol and the balance of water. The cellulose nano whisker antibacterial and moisturizing cream type mask disclosed by the invention can solve the problems of in the prior art that the used mask is inconvenient to deal with, the moisturizing effect is not good enough and the whitening is notobvious; the mask has good moisturizing property, realizes deep-layered and fast water supplement, and also has good anti-aging and antibacterial characteristics and can be applied to the applicationfields such as mask materials and daily chemical products.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a cellulose nano-whisker antibacterial and moisturizing cream mask, a preparation method and application thereof. Background technique [0002] The principle of the mask is to use the short time covered on the face to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote the secretion and metabolism of sweat glands, increase the oxygen content of the skin, and help the skin to eliminate epidermal cells. The products of metabolism and accumulated oily substances, the moisture in the mask penetrates into the stratum corneum of the skin epidermis, the skin becomes soft and elastic. At present, commercially available facial masks can be broadly divided into six types, namely mud paste facial masks, peel-off facial masks, jelly facial facial masks, cream facial masks, face patch facial masks and bubble facial...
