Description
Technical Field
The invention belongs to the field of natural polymer materials and cosmetics, and particularly relates to a preparation method of a modified cellulose facial mask base fabric with excellent moisturizing capability.
Background
Natural cellulose is the most abundant biological resource on the earth, and provides thousands of years of use value for human as a multifunctional, low-cost and renewable material; as an unlimited resource, cellulose can be repeatedly produced, decomposed, used and degraded according to the rules of nature; thus, cellulose derived from plants continues to become an energy source and be manufactured as a product as a renewable resource source; in particular, oxidized cellulose obtained by oxidizing such cellulose has an extremely strong ability to absorb moisture and store it, and is an optimum material as a material for the beauty field (e.g., mask base cloth).
As oxidized cellulose subjected to oxidation treatment, carboxymethyl cellulose (CMC) is a cellulose derivative, has recognized safety and efficacy, is simple to prepare, is biodegradable and harmless to a human body, and can replace all common non-woven fabric mask base fabrics appearing in the current market.
In particular, carboxymethyl cellulose (CMC) is a material obtained by reacting lignocellulose with NaOH alkali treatment of monochloroacetic acid (MCA), and has been widely used as a viscosity modifier and additive in the food industry, is safe and non-toxic, and has extremely high biocompatibility and use value.
Most of carboxymethyl cellulose (CMC) obtained by the above-mentioned method is in the form of powder, but when it is expanded to a wider range of applications such as cosmetic and medical uses, it is required to provide fibrous carboxymethyl cellulose such as carboxymethyl cellulose woven fabric, carboxymethyl cellulose nonwoven fabric and the like.
However, the methods for producing carboxymethyl cellulose woven fabrics and carboxymethyl cellulose nonwoven fabrics can only be produced in a laboratory scale, and currently, the total amount of industrial requirements of numerous production departments such as beauty treatment, medical treatment and the like is far from being met, so that the industrial production of carboxymethyl cellulose woven fabrics and carboxymethyl cellulose nonwoven fabrics is a problem which needs to be solved urgently at present.
In addition, in the case where a carboxymethyl cellulose woven fabric and a carboxymethyl cellulose non-woven fabric are used as a mask base fabric, there is no method of gradually releasing a functional active ingredient of a cosmetic onto the skin by uniformly mounting microcapsules of a polymer structure containing the functional ingredient of a skin care product on fibers.
Disclosure of Invention
In order to solve the above technical problems, there is provided a method for preparing a modified cellulose facial mask base fabric having excellent moisturizing ability, the production process of the facial mask base fabric using a technique of gelation of a natural cellulose derivative to prepare a carboxymethyl cellulose woven fabric or non-woven fabric that can be used in direct contact with the skin; the modified cellulose mask base cloth having excellent moisturizing ability is provided in a dry sheet form which is advantageous in maintaining the stability of soluble components in the skin and can be loaded with effective essences at a high content, uniformly disperse the effective essences by physical dispersion force upon contact with moisture and allow the effective absorption by the skin.
The specific technical scheme of the invention is as follows:
(a) the carboxymethyl cellulose woven or non-woven fabric is made of a material having a weight of 30 to 40 g/m2The method comprises the steps of immersing a cellulose woven fabric or a non-woven fabric into an alkali solution and padding for 30-60 min at 20-50 ℃;
(b) after the cellulose woven fabric or the non-woven fabric is completely filled with alkali liquor, curing for 30-60 min at 20-50 ℃ in order to dissociate hydrogen bonds of cellulose molecules;
(c) after the cellulose woven fabric or the non-woven fabric after dissociation is aged, a certain amount of carboxymethylation solution (monochloroacetic acid) is dissolved in a mixed solution of isopropanol and hyaluronic acid, and soaking is carried out for 30-90 min at the temperature of 50-80 ℃; obtaining a carboxymethyl cellulose woven fabric or non-woven fabric with hyaluronic acid load;
(d) after the reaction is completed, washing twice or three times with a water washing solution of isopropyl alcohol and water to remove unreacted substances in the natural cellulose derivative; at this time, phosphoric acid may be added during washing with water to adjust the pH to neutrality; after completion, the wet carboxymethyl cellulose woven or nonwoven fabric may be pressed using an automatic hand shaking and continuously dried at a temperature of 120 ℃ to obtain a dry sheet-like carboxymethyl cellulose woven or nonwoven fabric.
Preferably, the alkaline solution in the step (a) is 15-40% of NaOH, but if the concentration of the alkaline solution (NaOH) is less than 15%, the required substitution degree of the carboxymethyl cellulose cannot be obtained; if it exceeds 40%, the side reaction of NaOH is more and the substitution degree of carboxymethyl cellulose is too high, making it unsuitable for production; when the filling rate is less than 300%, the hydrophobic bond of the cellulose molecule is not sufficiently dissociated by the alkali, and thus the substitution degree of the hydrophilic carboxyl group is low, and when it exceeds 400%, the nonwoven fabric is damaged.
In the step (a), the carboxymethyl cellulose woven or nonwoven fabric of the present invention is composed of a material having a weight of 30 to 40 g/m2The low weight of the natural cellulose of (1) is obtained because if the weight range is out of the above range, gelation occurs upon contact with moisture, the degree is low and the mechanical properties are poor, and the preparation conditions are not preferred.
In the step (b), in order to dissociate hydrogen bonds of cellulose molecules, curing is carried out for 30-60 min at 20-50 ℃; the aging temperature is performed at a lower temperature than the conventional continuous alkali treatment method, in which the reaction is insufficient if the aging temperature is lower than 20 ℃ and the reaction is rapidly and uniformly performed in the production of carboxymethyl cellulose if it exceeds 50 ℃.
Preferably, the ratio of isopropanol in step (c): the volume ratio of hyaluronic acid is controlled to be 99: 1-97: 3, and the MCA content is 20-60%.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a modified cellulose facial mask base cloth with excellent moisturizing capability, wherein a dry film of the modified cellulose facial mask is changed into a semi-gel shape when meeting water; more effective in skin absorption due to excellent hydrogel properties, finely dispersed and dissolved in the skin by physical dispersion force upon contact with moisture; in the preparation process, the hyaluronic acid microspheres are added to the carboxymethyl cellulose woven or non-woven fabric fibers, so that the modified cellulose mask base cloth is endowed with excellent water retention capacity to a great extent; more specifically, the modified cellulose mask base fabric having excellent moisturizing ability of the present invention can ensure the stability and natural decomposition of the skin due to the use of the environment-and human-friendly cellulose material. And due to physical dispersion ability, the carboxymethyl cellulose woven or nonwoven fabric is uniformly dispersed in a state invisible to the naked eye and can be simply removed by washing with running water after use.
