Embodiment 1

[0025] Example 1: Compound whitening and freckle removing cream

[0026] This example discloses the formula of compound whitening and freckle-removing cream and its preparation method, and its formula is shown in Table 1.

[0027] Table 1

[0028]

[0029] Wherein, the raw material percentage by weight of the active part extract of the traditional Chinese medicine is: 20% of grape seed, 20% of Rhizoma Chuanxiong, 10% of Peony, 20% of Cortex Mori, 12% of Hibiscus, and 18% of Glycyrrhiza glabra.

[0030] The preparation method of the compound whitening and freckle-removing cream of the present embodiment is realized in this way:

[0031] (1) The extraction and purification method of the active part extract of traditional Chinese medicine is as follows:

[0032] Mix and pulverize the raw materials of grape seed, Chuanxiong, Peony, Morus alba, Hibiscus, and Glycyrrhiza glabra into coarse powder, soak in 40% ethanol according to the ratio of 1:8 drug to solvent, soaking time...

Embodiment 2

[0038] Example 2: Compound whitening and freckle removing cream

[0039] This example discloses the formula of compound whitening and freckle-removing cream and its preparation method, and its formula is shown in Table 2.

[0040] Table 2

[0041]

[0042] Wherein, the raw material weight percent of the active part extract of the traditional Chinese medicine is: grape seed 18%, Chuanxiong 18%, Peony 10%, Morus alba 20%, Hibiscus 15%, Glycyrrhiza glabra 19%.

[0043] The manufacturing method of the invention described in the embodiment of the present invention is basically the same as that of Example 1, the difference is: the ethanol concentration used to soak the medicinal powder in the step (1) is 60%, and the active part extract raw material of the described Chinese medicine is mixed with ethanol The ratio is 1:10, the soaking time is 20 hours, and the concentration of ethanol used for elution is 75%.

Embodiment 3

[0044] Example 3: Compound whitening and freckle removing cream

[0045] This example discloses the formula of compound whitening and freckle-removing cream and its preparation method, and its formula is shown in Table 3.

[0046] table 3

[0047]

[0048] Wherein, the raw material percentage by weight of the active part extract of the traditional Chinese medicine is: grape seed 15%, Chuanxiong 23%, Peony 15%, Morus alba 20%, Hibiscus 12%, Glycyrrhiza glabra 15%.

[0049] The manufacturing method of the invention described in the embodiment of the present invention is basically the same as that of Example 1, except that the ethanol concentration of soaking the medicinal powder is 50%, and the soaking time is 30 hours. The type of macroporous resin used for purification was AB-8, and the concentration of ethanol used to elute from the macroporous resin column was 70%.

Abstract

The invention specifically discloses composite whitening and banishing essence and a preparation method thereof. The composite whitening and banishing essence comprises the following raw materials in percent by weight: 1 to 25 percent of Chinese herb active site extract, 0.1 to 10 percent of ethylhexyl ferulate, 0.1 to 5 percent of vitamin C ethyl ether, 0.05 to 3 percent of nicotinamide, 10 to 40 percent of grease, 1 to 6 percent of emulsifier, 1 to 15 percent of moisturizing agent, 0.1 to 1.5 percent of preservative, 0.1 to 0.5 percent of essence and the balance of deionized water. By virtue of the composite whitening and banishing essence, the activity of tyrosinase can be effectively inhibited, oxygen free radicals are efficiently eliminated, forming of melanin is prevented, and the formed melanin is decomposed and faded; meanwhile, an endocrine system of a human body can be regulated, and injuries to the skin caused by chemical components such as hormone are repaired, so that effects of treating both symptoms and root causes comprehensively and quickly are achieved.

Description

technical field [0001] The invention relates to a compound whitening and freckle-removing cream, in particular to a compound whitening and freckle-removing cream and a preparation method thereof. Background technique [0002] Everyone has a desire for beauty, but many women are troubled by freckles and melasma on their faces.
