Problems solved by technology

[0011] Similarly, although freeze-dried powder technology has its advantages, it also has certain disadvantages, such as the process is relatively complicated, it needs to be frozen, evacuated, and the preparation time is long
More importantly, some freeze-dried powders are difficult to quickly dissolve in pure water and cannot form hydrogels, which affects the effect of skin care

Embodiment 1

[0066] Such as Figure 1-5 As shown, the beauty and skin care product of the present invention includes a packaging body 1, a packaging body 2 and contents, wherein, the packaging body 1 and the packaging body 2 can form a sealed packaging space for accommodating the contents, and when in use Sometimes the packaging body 1 and the packaging body 2 can be at least partially separated from each other by external force; the content is one or several aggregates formed by silk fibroin nanofibers with a diameter between 0.10 μm and 0.70 μm.

Embodiment 2

[0067] Embodiment 2: the preparation of silk fibroin nanofiber

[0068] Prepare the silk fibroin nanofibers used in the cosmetic and skin care products of the present invention as follows:

[0069](1) Preparation of spinning solution: use pure water as solvent, add silk fibroin (purchased from Suzhou SMETE Biotechnology Co., Ltd.), sodium hyaluronate, maltooligosaccharide glucoside, hydrogenated starch hydrolyzate, PEG- 7M, PEG-180, polyglyceryl-10 myristate, pullulanase polysaccharide, preservative, stirred in a constant temperature water bath at 20°C-50°C for 2-6 hours until the solution is uniform and free of particles, and the following Component spinning solution: 18wt% silk fibroin, 0.2wt% sodium hyaluronate, 2.0wt% pullulanase polysaccharide, 2.4wt% maltooligoglucoside, 1.4wt% hydrolyzed hydrogenated starch material, 0.5wt% PEG-7M, 0.3wt% PEG-180, 0.1wt% polyglycerol-10 myristate, and 1.0wt% preservative, wherein the average molecular weight of sodium hyaluronate used ...

Abstract

The invention discloses a dry beauty skin care product. The product comprises a packaging body and a content; the packaging body comprises a packaging body 1 and a packaging body 2, wherein the packaging body 1 and the packaging body 2 can form a sealed packaging space for accommodating the content; and moreover, when in use, the packaging body 1 and the packaging body 2 can be at least partiallyseparated from each other through an external force, wherein the content is a pile body of silk fibroin nanofibers with the diameter of 0.10mum to 0.70mum. The beauty skin care product disclosed by the invention is formed by the dry silk fibroin nanofibers before in use; the stability of each active component can be well maintained; even preservatives are not required; and the beauty skin care product can be quickly dissolved in water to form hydrogel when in use, so that the effects of various active components can be better taken.

Description

technical field [0001] The invention relates to a beauty and skin care product, more specifically, the invention relates to a beauty and skin care product using dry silk fibroin nanofibers. Background technique [0002] The skin is composed of several layers of cells, which can cover and protect the keratin and collagen fibers that make up its structural skeleton, the outermost layer of which is the stratum corneum. Anionic surfactants and organic solvents can generally penetrate the stratum corneum membrane and destroy the surface shape of the skin through degreasing, resulting in a rough feeling, causing the surfactant or solvent to interact with keratin to produce irritation. [0003] It has been found that maintaining a proper water gradient on both sides of the stratum corneum is critical for its function. Most of this water comes from within the body and acts as a plasticizer for the cuticle. If the humidity is too low, such as in cold climates, there is not enough w...
