Embodiment 1

[0075] Embodiment 1: the preparation of tangerine peel extract

[0076] The preparation of tangerine peel extract of the present invention comprises the following steps:

[0077] (1) Weigh and crush Xinhui tangerine peel: weigh 1g of Xinhui tangerine peel, crush and sieve;

[0078] (2) Extraction: add the crushed tangerine peel in step (1) to 20ml of 50% extraction solvent for soaking. The extraction solvent is composed of ethanol and ethylene glycol with a mass ratio of 3:1, and add 0.1 g of citric acid, supplemented by ultrasound, and heated to 55°C for extraction, extracted 3 times, each time for 2 hours, filtered, the filtrates were combined, concentrated under reduced pressure until the amount of extraction solvent was 10%, and the filtrate was obtained;

[0079] (3) Drying: Freeze-dry the filtrate obtained in step (2) to obtain a light yellow tangerine peel extract.

[0080] The determination of the flavonoid content in the tangerine peel extract is to first prepare th...

Abstract

The invention belongs to the technical field of cosmetics, and specifically discloses a composition with whitening function, which can be applied to whitening cosmetics. The composition with whitening function includes: propolis extract, tangerine peel extract and epidermal growth factor, the weight ratio of which is (1-5):(0.5-3):(0.01-0.5). The present invention uses natural and non-irritating substances as the raw materials of the whitening composition, and through the synergistic effect of the ingredients, it regulates and maintains the skin, and has the structure of anti-inflammatory, anti-allergic, strong anti-oxidation, inhibition of tyrosinase activity, and regulation of the stratum corneum , Promote cell regeneration to achieve skin whitening, enhance skin gloss and transparency, and improve people's dry, dull, sallow and dull skin problems.

Description

technical field [0001] The invention belongs to the technical field of cosmetics and relates to a compounded natural composition, in particular to a composition with whitening function, which can be applied to whitening cosmetics.
