Description

Compound with multiple-effect repairing and anti-aging effects and preparation method thereof

With the improvement of living standard, consumers are paying more attention to the ingredients and efficacy of cosmetic formulations. However, highly active ingredients are often unstable in physicochemical properties, and particularly lose or lose activity very easily under normal temperature and liquid conditions. Because the vacuum freeze-drying technology is carried out in a low-temperature and low-oxygen environment, most biological reactions are stagnant, liquid water is not present in the treatment process, and moisture is directly sublimated in a solid state, so that the damage to the structure and the characteristics of tissues and cells is small, the original structure and the shape of the materials are protected to the greatest extent, meanwhile, the freeze-drying technology effectively retains the original characteristics of components, particularly improves the stability of a plurality of thermosensitive active components, protects and retains the activities of some higher biological activity or easily-oxidized components, and finally can obtain a high-quality dried product with both appearance and internal quality. The color of the freeze-dried powder product is not changed basically after drying, the morphological structure is loose, and the freeze-dried powder product can be quickly dissolved and restored to a solution form after being added with solvents such as water and the like, and the freeze-dried powder product presents the original physicochemical property and biological activity. In addition, in view of the preparation principle of the freeze-dried powder, the moisture content in the freeze-dried powder is very low, so that the stability of the product is greatly improved, the transportation is convenient, and the storage life of the product is prolonged.
CN 114259418A discloses a polypeptide lyophilized powder comprising a peptide and an excipient to which the peptide is easily attached; the peptide comprises 0.1-2 parts by weight of oligopeptide-1, 0.1-2 parts by weight of tripeptide-1 and 0.1-2 parts by weight of oligopeptide-1; the excipient comprises mannitol 4-25 weight parts, disodium hydrogen phosphate 0.5-1.0 weight parts, and sodium dihydrogen phosphate 0.6-1.2 weight parts. The polypeptide freeze-dried powder preparation can be prepared by compounding the freeze-dried powder and solvent liquid. The method effectively protects the stability of the effective components of a plurality of thermosensitive biological products. But the freeze-dried powder adopts single polypeptide component, the used oligopeptide-1 has safety risk, and the development of the freeze-dried powder and the compound preparation with safer and more comprehensive efficacy has good market prospect.

The raw materials of the freeze-dried powder preparation comprise the following components: mannitol, dipotassium glycyrrhizinate, cell complex biological peptide, tripeptide-1 copper, nicotinamide, glycyrrhiza glabra root extract and grape seed extract. The lyophilized powder preparation has four-in-one effects of moisturizing, whitening, relieving and repairing.
Due to the morphological characteristics of the freeze-dried powder, the freeze-dried powder is matched with a solvent liquid for use in application, and the solvent liquid plays a key role in the performance of the functional components of the freeze-dried powder. Patent CN 115212133A discloses a freeze-dried powder solvent, which is prepared from water, glycerol, propylene glycol, 1, 2-hexanediol, p-hydroxyacetophenone, butanediol, saccharide isomers, trehalose and oat peptide.

3. Test of soothing efficacy
The current study considers the occurrence of sensitive skin as a complex process involving skin barrier-neurovascular-immune inflammation. Hyaluronic acid is the component with the largest content and proportion in the extracellular matrix, can maintain the volume of the extracellular matrix, regulate and control the secretion of cell growth factors and cytokines, and influence the adhesion, growth, proliferation and differentiation of cells, thereby playing an important role in maintaining the skin moisture and elasticity, wound healing, angiogenesis and other processes.
Hyaluronidase is an endogenous amino hexose which causes the decomposition of macromolecular hyaluronic acid, has strong correlation with inflammation and allergy, and researches report that various medicines for releasing histamine by fat large cells can regulate the activity of the hyaluronidase, and some antiallergic medicines have strong inhibition of the activity of the hyaluronidase, so that the inhibition of the activity of the hyaluronidase is used as an index for researching the antiallergic effect.
The macromolecular hyaluronic acid is decomposed to generate the N-acetylglucosamine under the action of hyaluronidase, and the activity of the hyaluronidase can be indirectly reacted by measuring the N-acetylglucosamine content in a reaction system. The inhibition of the activity of the hyaluronidase can ensure the normal content and function of the hyaluronic acid, so that whether a test sample has the effect of relieving or not can be judged by utilizing the inhibition rate of the hyaluronidase activity, and the higher the inhibition rate of the hyaluronidase activity is, the stronger the relieving effect of the substance is reflected, and the weaker the relieving effect is on the contrary.
The testing method comprises the following steps:
and (3) taking a proper amount of sample and a solution of hyaluronidase and the like for color reaction, testing absorbance at 530nm, and calculating the inhibition rate (%) of the hyaluronidase activity.
Hyaluronidase inhibition ratio (%) = [ (C-D) - (a-B) ]/(C-D) ×100%;
wherein: OD value of a- (hyaluronidase + sample + potassium hyaluronate) sample solution;
OD value of B- (hyaluronidase + sample + acetate buffer) sample blank;
OD value of C- (hyaluronidase + deionized water + potassium hyaluronate) control solution;
d- (acetate buffer + deionized water + acetate buffer) versus OD value of blank.
The results of the soothing efficacy evaluation of the above examples and comparative examples are shown in Table 5 below.

The sample was used once in the morning and evening by the test person, and data were collected after 4 weeks of continuous use. The change of the melanin content of the skin of the subject before and after the sample is tested is evaluated, so that the whitening effect is determined. The corresponding test results are shown in table 6 below.
Wherein, the melanin content change rate Δmi% = (T n -T 0 )/T 0 Averaging the final result; the higher Δmi% reduction value indicates better whitening efficacy.
Wherein T is n -the melanin content value of the tested area after 4 weeks of continuous use; t (T) 0 -initial value of melanin content of the test area.
