Micromolecular hyaluronic acid stock solution and preparation method thereof

Abstract

The invention relates to a micromolecular hyaluronic acid stock solution. The micromolecular hyaluronic acid stock solution comprises the following components in parts by weight: 8-10 parts of a skinconditioning agent, 3-5 parts of a skin repellent, 8-10 parts of a hydrating agent, 1.5-2.5 parts of an antioxidant, 0.05-0.15 part of a chelating agent and 70-80 parts of a solvent. The invention also discloses a preparation method of the micromolecular hyaluronic acid stock solution. The preparation method comprises the following steps of S1, cleaning equipment; S2, heating the solvent and the hydrating agent to 80-90 DEG C, and performing heat insulation; S3, performing vacuum homogenizing; S4, performing vacuum constant-temperature defoaming; S5, performing cooling to 45 DEG C, adding theskin conditioning agent, the skin repellent, the antioxidant and the chelating agent, and performing vacuum and uniform stirring; S6, performing cooling to 38 DEG C, performing half-part inspection, and discharging qualified products; and S7, performing filling to obtain finished products. The micromolecular hyaluronic acid stock solution disclosed by the invention has the advantages of being simple in technology, convenient to use, safe and reliable, and free from substances harmful to human bodies; and besides, natural extracts are massively used, so that using safety can be well guaranteed,damage to human bodies and skin can be reduced, and the micromolecular hyaluronic acid stock solution has the effects of regulating skin fat secretion, keeping moist and tenderizing and whitening skin.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a small molecule hyaluronic acid stock solution and a preparation method thereof. Background technique [0002] With the growth of people's age and the influence of nutrition, sunshine, environment and other factors, the ability of the human body to synthesize hyaluronic acid (hyaluronic acid) HA gradually decreases, and the content of hyaluronic acid (hyaluronic acid) HA in the skin will gradually decrease. The content of hyaluronic acid (hyaluronic acid) HA in the body is the highest, and it gradually decreases after birth. If the relative content of hyaluronic acid (hyaluronic acid) HA in a human body at the age of 20 is positioned at 100%, then it will drop to 65%, 45%, and 25% at the age of 30, 50, and 60, respectively. When the hyaluronic acid (hyaluronic acid) HA content in the skin is lower than a certain level, the water content of the skin surface will gradually decr...
