preparation example Construction

[0034] This embodiment also provides a preparation method of an essence composition with whitening effect, which includes the following steps:

[0035]Step 1: First add the water, EDTA-2Na, dipotassium glycyrrhizinate, and nicotinamide into the emulsification pot, then take a container, weigh sodium hyaluronate and a part of propylene glycol into it and disperse evenly, and add emulsification after the dispersion is even in a pot, set aside;

[0036] Step 2: Take a container, weigh the methylparaben and the remaining propylene glycol into it and heat it to completely dissolve the methylparaben, then add it to the emulsification pot in step 1; stir and heat to fully dissolve each component, and keep warm at one end Cool down after a while and set aside;

[0037] Step 3: Take a container and add methylpropanediol, 1,2-pentanediol, phenoxyethanol\ethylhexylglycerin into it and disperse evenly, then add it to the emulsification pot in step 2, stir evenly, and set aside;

Abstract

The invention relates to the technical field of cosmetics, and particularly relates to an essence composition with a whitening effect and a preparation method and application thereof. The essence composition with the whitening effect comprises the components of, by mass, 0.05% to 0.4% of sodium hyaluronate, 0.02% to 0.1% of EDTA-2Na, 0.05% to 0.2% of dipotassium glycyrrhizinate, 1.0% to 10.0% of nicotinamide, 1.0% to 6.0% of propylene glycol, 1.0% to 5.0% of methyl propylene glycol, 0.5% to 1.5% of 1, 2-pentanediol, 1.0% to 5.0% of citrus peel extract, 0.1% to 1.2% of preservative and 70.6% to95.28% of deionized water. The essence composition with the whitening effect, provided by the invention, is mild in formula and low in irritation, and can be used for uniformly brightening the skin color, improving the dull skin, enabling the skin to be smooth and transparent and improving the skin barrier.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an essence composition with whitening effect and its preparation method and application. Background technique [0002] In today's society, people's pursuit of high-value beauty is becoming more and more prominent. Fair and rosy skin may be the pursuit of most Chinese people. The amount and distribution of melanin content in the epidermis is the main reason for determining the skin color of a person. Melanin is produced by melanocytes. The production and consumption of melanin mainly have the following pathways: tyrosine is produced under the catalysis of tyrosinase Dopa, DOPA is further oxidized and polymerized to form melanin; a part of melanin is transferred to keratinocytes through dendrites, and melanin migrates to the stratum corneum along with keratinocytes, and finally falls off with keratinocytes; another part of melanin migrates to the superficial layer of the dermis, ...
