Embodiment 1

[0040] Embodiment 1: A kind of skin whitening composition, it comprises A phase and B phase, and described A phase comprises the component of following parts by weight: 2 parts of licorice root extract, 28 parts of methyl propylene glycol, 1,3 - 60 parts of propylene glycol; the phase B includes the following components in parts by weight: 10 parts of hexyl resorcinol, 30 parts of 1,3-propylene glycol, 30 parts of polyethylene glycol, and 0.014 parts of hydroxycinnamic acid. The preparation of described A phase comprises the following steps:

[0041] Step 1: Take corresponding parts by weight of 1,3-propanediol and 1 / 2 of methylpropanediol and mix them evenly, then heat to 50°C;

[0042] Step 2, adding the licorice glabra root extract in corresponding parts by weight, stirring at a constant temperature, the stirring speed is 700rpm / min, the stirring time is 0.5h, and the temperature is maintained at 45°C;

[0043] Step 3, lower the temperature to 35°C, add the corresponding 1...

Embodiment 2-7

[0057] Embodiment 2-7: A skin whitening combination, the difference from Embodiment 1 is that each component and its corresponding weight parts are shown in Table 1.

[0058] Each component and parts by weight thereof in table 1 embodiment 1-7

[0059]

[0060]

Embodiment 8

[0061] Example 8: A skin whitening combination, the difference from Example 1 is that in the preparation step of Phase A, Step 2 is specifically set as: adding 0.02 parts by weight of phloretin and corresponding parts by mass Several Glycyrrhiza glabra root extracts were stirred at a constant temperature, the stirring speed was 700 rpm / min, the stirring time was 0.5 h, and the temperature was maintained at 45°C.

Abstract

The invention discloses a skin whitening composition and a preparation process thereof, mainly relates to the technical field of skin care products, and solves the problem that overall whitening effect is poor as the effects of whitening components in the existing skin care products are single. The skin whitening composition comprises a phase A and a phase B, the phase A comprises, by weight, 0.05-2 parts of glycyrrhiza glabra root extracts, 20-28 parts of methylpropanediol, 60-70 parts of 1, 3-propylene glycol, 0.02-2 parts of phloretin, 0.01-0.2 part of ethylhexylglycerin and 1-5 parts of 1,2 parts of pentylene glycol. The phase B comprises, by weight, 1-10 parts of hexylresorcinol, 25-30 parts of 1, 3-propylene glycol, 30-60 parts of polyethylene glycol-4 and 0.08-0.014 part of hydroxycinnamic acid. The phloretin has good inhibition effect on activity of tyrosinase, and the tyrosinase inhibition ratio of the skin whitening composition can be greatly increased when the phloretin, theglycyrrhiza glabra root extracts and the hydroxycinnamic acid are compounded, so that the skin whitening composition has good whitening effects.

Description

technical field [0001] The invention relates to the technical field of skin care products, more specifically, it relates to a skin whitening composition and a preparation process thereof. Background technique [0002] Melanin is a protein present in the basal layer of everyone's skin. The irradiation of ultraviolet rays will change the melanin to produce a substance that protects the skin, and then the melanin moves through the layers of cell metabolism to the epidermis of the skin, forming skin problems such as spots and uneven skin tone that we see. [0003] In the prior art, such as a Chinese patent with the patent notification number CN106580755 proposes a nano composition containing moisturizing and whitening ingredients and its preparation method, which includes the following components in mass percentage: liquid lipid 0.1-10%, 0.01-2% of resorcinol derivatives, 0.01-10% of vitamins and their derivatives, 0.1-15% of surfactants, 0.1-10% of co-emulsifiers, 0.1-15% of p...
