Problems solved by technology

The traditional decoction extraction method is easy to destroy the small molecular peptides of Dendrobium officinale, and the ordinary grinding method will contain more impurities, which is not easy to separate the small molecular peptides
The efficiency of these conventional methods to obtain small molecular peptides from Dendrobium officinale is too low, so we need to explore new methods

Embodiment 1

[0021] 1. Normal temperature and high pressure pretreatment and compound enzymatic hydrolysis preparation technology

[0022] According to the structural characteristics of Dendrobium officinale protein, high-dispersion Dendrobium officinale pretreatment solution was obtained by using normal temperature and high pressure pretreatment technology The dendrobium was dried (40° C.), pulverized, passed through a 60-mesh sieve, added a certain proportion of water to the obtained powder, stirred evenly, and soaked for 10 minutes to soften. Adjust the upper and lower limit temperature of the low-temperature circulating pump to -10°C to -4°C to ensure that the internal temperature of the homogenizer is at room temperature. Pour the mixed material into a high-pressure homogenizer. The material is first placed under low pressure conditions (5-10MPa), and then the valve is adjusted to 40-50MPa. After the pressure is stable, homogenize several times; the obtained homogeneous solution is ce...

[0027] [Example 2] Preparation of facial mask essence and facial mask packaging

[0028] The composition of facial mask of the present invention is as follows:

[0029]

[0030]

[0031] The nano-gold rods used in the present invention are prepared by the in-situ method, and the modified polysaccharide-based block copolymer SA-PVP is used as a stabilizer, wherein the amount of SA-PVP is 11%, and the seaweed polysaccharide unit in the copolymer SA-PVP has Strong complexing ability, can form complexes with multivalent metal ions, and effectively snatch heavy metal ions from the skin. The prepared nano-gold rods have an average diameter of about 10nm and an average length of about 60nm, and have obvious photothermal effect.

[0032] The preparation method of the facial mask of the present invention is as follows: fully mix the above-mentioned ingredients, stir and homogenize to obtain the mask essence in a transparent or translucent emulsion; send the mask essence for insp...

[0033] [Example 3] Product Quality Inspection

[0034] Microbiology test: The test items include the total number of colonies, fecal coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, mold and yeast. Evaluation criteria: the total number of colonies ≤ 1000cfu / ml (g); the total number of mold and yeast ≤ 100cfu / ml (g); fecal coliforms, Pseudomonas aeruginosa, and Staphylococcus aureus cannot be detected. Any ≥ 1 indicator that does not meet the standard is judged as a substandard sample.

Abstract

The invention discloses a dendrobium officinale small-molecular peptide facial mask based on a gold-nano rod composite material. The facial mask comprises a facial mask fabric and essence, and is characterized in that the essence is prepared from the following components in percentage by mass: 84.05 percent of water, 0.1 percent of Carbomer, 6.0 percent of glycerinum, 1.0 percent of dendrobium officinale small-molecular peptide, 1.0 percent of gold nano-rod, 1.0 percent of polyethylene glycol-32, 0.03 percent of xanthan gum, 0.02 percent of EDTA-2Na, 1.0 percent of glycine betaine, 4.0 percent of hyaluronic acid, 1.0 percent of beta-glucan, 1.0 percent of chondrus crispus, 0.1 percent of triethanolamine, 0.3 percent of PEG-40 hydrogenated castor oil, 0.1 percent of essence, 0.18 percent of 3-Iodopropynyl butylcarbamate and 0.12 percent of dimethylol dimethyl hydantoin. Since dendrobium officinale small-molecular peptide and nano-gold composite material are added, the facial mask can be used for repairing damaged skin, inhibiting bacterium production, keeping skin tight, removing wrinkles, nourishing, moistening and whitening skin and relieving speckles.

Description

technical field [0001] The invention relates to the field of preparation of cosmetics, and in particular discloses a dendrobium officinale small molecule peptide facial mask. Background technique [0002] The mask blocks the contact between the skin and the air, inhibits sebum secretion and sweat evaporation, and makes the skin temperature rise. After the skin temperature rises, it will promote blood circulation, so that the active ingredients in the mask can penetrate into the surface layer or deeper and wider places. [0003] Currently on the market, polysaccharides are mainly extracted from Dendrobium officinale for the preparation of oral medicines, and the extraction and utilization of small molecular peptides is relatively small. The invention extracts the dendrobium candidum small molecule peptide, which is used for preparing facial mask. The traditional decoction extraction method is easy to destroy the small molecular peptides of Dendrobium officinale, and the ordi...
