Bifidus yeast freeze-dried powder composition and preparation method thereof

Abstract

The invention discloses a bifidus yeast freeze-dried powder composition and a preparation method thereof. The bifidus yeast freeze-dried powder composition comprises powder and an aqueous solution, wherein the powder comprises the following raw materials: bifidus yeast fermentation product filtrate, oligopeptide-1, a pH regulator, mannitol and the balance of water; the water aqua comprises the following raw materials: a skin conditioner, a humectant, a chelating agent, an antioxidant, an excipient and the balance of water. The bifidus yeast freeze-dried powder composition provided by the invention comprises the powder and the water aqua, the use effect is prevented from being influenced by mixing and dissolving of powder components and water aqua components through independent packaging of the powder and the water aqua, and when the bifidus yeast freeze-dried powder composition is used, the powder and the water aqua are uniformly mixed and then smeared on the skin, so that the skin is not irritated; test results show that through scientific and reasonable proportioning, the obtained water aqua can promote skin metabolism, improve the skin permeation effect of the active ingredients of the powder and enhance the effects of moisturizing and brightening the skin, and the efficiency of repairing damaged skin is high through the synergistic effect of the water aqua and the active ingredients.

Description

technical field

[0001] The invention relates to the technical field of cosmetics, in particular to a bifid yeast freeze-dried powder composition and a preparation method thereof. Background technique

[0002] Freeze-dried powder is a powder obtained by freezing a liquid into a solid in a low-temperature environment and then drying it, which can avoid the damage of active ingredients by heating to the greatest extent, and was first used in the production of heat-sensitive medicines or biological products. With the continuous development of technology, freeze-dried powder cosmetics have received more and more attention. In cosmetics, lyophilized powder is usually used together with a solvent (such as water), but in such cosmetic preparations with lyophilized powder and solvent, most of the active ingredients exist in the lyophilized powder, and the optimization of the solvent formula is ignored, resulting in The skin repair effect is not significant, and it must be used with ...
