Embodiment 1
[0022] Embodiment 1: freckle-removing and whitening lotion (the weight ratio of Pterotaceae extract and Sclerophyllum extract is 3:1)
[0023] A freckle-removing and whitening lotion is composed of a carrier component and a functional component, and comprises the following components by weight:
[0024] Carrier components: 12 parts of glycerin, 6 parts of butanediol, 6 parts of 1,2-pentanediol, 74 parts of deionized water;
[0026] After the carrier components are weighed according to the dosage, start the stirrer and stir for 30 minutes. When the temperature is lowered to 45°C with circulating cooling and stirring, add the active ingredients while stirring until the mixture is uniform.
Embodiment 2
[0027] Embodiment 2: freckle-removing and whitening lotion (the weight ratio of the extract of Ptera pterygium and the extract of Sepia chinensis is 2:1)
[0028] A freckle-removing and whitening lotion is composed of a carrier component and a functional component, and comprises the following components by weight:
[0029] Carrier components: 12 parts of glycerin, 6 parts of butanediol, 6 parts of 1,2-pentanediol, 74 parts of deionized water;
[0031] After the carrier components are weighed according to the dosage, start the stirrer and stir for 30 minutes. When the temperature is lowered to 45°C with circulating cooling and stirring, add the active ingredients while stirring until the mixture is uniform.
Embodiment 3
[0032] Embodiment 3: freckle-removing and whitening lotion (the weight ratio of Pterotaceae extract and Sclerophyllum extract is 4:1)
[0033] A freckle-removing and whitening lotion is composed of a carrier component and a functional component, and comprises the following components by weight:
[0034] Carrier components: 12 parts of glycerin, 6 parts of butanediol, 6 parts of 1,2-pentanediol, 74 parts of deionized water;
[0036]After the carrier components are weighed according to the dosage, start the stirrer and stir for 30 minutes. When the temperature is lowered to 45°C with circulating cooling and stirring, add the active ingredients while stirring until the mixture is uniform.

Abstract
The invention discloses a plant-extract-based freckle removing and whitening cosmetic which comprises functional components a pterocephalus hookeri heck extract and a potamogeton distinctus extract, wherein the weight ratio of the pterocephalus hookeri heck extract to the potamogeton distinctus extract is (2-4):1. A preparation method for the pterocephalus hookeri heck extract and the potamogeton distinctus extract comprises the following steps: performing hot reflux extraction on dry pterocephalus hookeri heck and potamogeton distinctus with ethanol, combining filtrate, and performing concentration until ethanol smell disappears to obtain an ethanol extract concentrate; diluting the ethanol extract concentrate with water, and performing extraction sequentially with petroleumether, ethyl acetate and water-saturated butanol; dissolving butanol extract in water, performing filtration, enriching active ingredients in filtrate with macroporous resin, and performing spray drying. According to the freckle removing whitening cosmetic, the plant extracts are adopted as the functional components, and the content ratio of the pterocephalus hookeri heck extract to the potamogeton distinctus extract is controlled, so that freckle removing and whitening effects can be maximized. The freckle removing and whitening cosmetic is safe and effective.
Description
technical field [0001] The invention relates to the field of cosmetics, in particular to a freckle-removing and whitening cosmetic based on plant extracts. Background technique [0002] Skin is an important part of the human body, and it is also a symbol that directly expresses the health and aging of the human body. When the skinmetabolism is strong, the blood circulation is smooth, and the nutrition is rich, the skin is delicate, smooth, tender, highly elastic, and less prone to wrinkles and stains. When skinmetabolism is weakened, blood circulation is poor, and nutrients are poor, the skin will become dull, aging, and prone to wrinkles and stains. [0003] According to market research, in the Asian beauty and skin care market, freckle removal and whitening are still the most concerned topics for consumers. Traditional freckle-removing and whitening products are mostly chemical whitening preparations, although the effect is obvious, but the safety is low, the probabili...
