preparation example Construction

[0046] The preparation method of nasturtium extract is as follows:

[0047] S1. Wash and dry the nasturtium raw material, crush it through a 300-mesh sieve, and obtain the nasturtium powder;

[0048] S2. Take 50 parts by weight of nasturtium powder, add 500 parts by weight of 1mol / L sodium hydroxide aqueous solution, and extract under reflux for 3 times at 80° C., extract for 1 hour each time, cool, and filter to obtain filter residue and alkaline water extract;

[0049] S3. Take all the filter residues in S2, add 500 parts by weight of 60wt% ethanol aqueous solution, reflux extraction at 60°C for 3 times, each time for 1h, and cool and filter to obtain an ethanol extract;

[0050] S4. After adjusting the pH value of the alkaline water extract to neutrality with 2mol / L hydrochloric acid, combine the ethanol extract, concentrate under reduced pressure at 55°C to 1 / 20 of the volume of the alkaline water extract, filter, and dilute the filtrate with 5BV The flow rate of / h passe...

Embodiment 1

[0065] Freckle-removing and whitening essence, composed of the following raw materials: 5wt% glycerol, 2wt% 1,3-butanediol, 2.5wt% plant active substances, 1wt% erythritol, 0.35wt% trehalose, 0.55wt% spearmint Geranium oil, 0.3wt% dioctyl succinate sodium sulfonate, 0.4wt% glyceryl monocaprylate, 0.3wt% hydroxylecithin, 0.3wt% behenyl alcohol, 0.35wt% hydroxyethyl cellulose, 0.25wt% % betaine, 0.03wt% O-cymene-5-ol, 0.02wt% chlorphenesin, 0.35wt% raspberry ketone, 0.15wt% phenylalanine, 0.2wt% Scrophulariaceae extract, balance for deionized water.

[0066] The preparation method of the freckle-removing and whitening essence comprises the following steps: mixing the raw materials according to the formula, homogenizing in a homogenizer for 50 minutes after uniform stirring, with a homogenizing pressure of 25 MPa; cooling and discharging after passing the inspection to obtain the product.

[0067] The plant active substance is composed of 10 parts by weight of nasturtium extract...

Embodiment 2

[0110] Basically the same as Example 1, the difference is only that the preparation method of the persimmon leaf extract is as follows:

[0111] X1, wash and dry the persimmon leaves, and pass through a 150-mesh sieve to obtain the persimmon leaf powder;

[0112] X2. Take 50 parts by weight of persimmon leaf powder, add 800 parts by weight of deionized water and mix evenly, heat to 90°C, stir and extract at 600rpm for 6h, filter to obtain a primary filtrate and a primary filter residue, and the primary filter residue is 1g according to the solid-liquid ratio: Add 5mL into 60wt% ethanol aqueous solution, heat to 70°C, stir at 600rpm for 4h, filter to obtain the secondary filtrate and secondary filter residue, combine the primary filtrate and the secondary filtrate, and store in a vacuum of -0.04MPa and a water bath temperature of 70°C Concentrate under reduced pressure to 1 / 10 of the total volume of the primary filtrate and the secondary filtrate to obtain a concentrated soluti...

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a freckle-removing and whitening essence and a preparation method thereof. Background technique [0002] Fair and clean skin not only represents a person's good image, but also reflects their good health. However, with age and the influence of ultraviolet rays and pollutants in the environment, the skin will accumulate metabolites such as melanin to form spots, making the skin condition worse. Current whitening cosmetics mainly include chemical and biological whitening products, among which salicylic acid, arbutin, nicotinamide and other active substances can achieve whitening effect by inhibiting the activity of tyrosinase in melanocytes. In contrast, bio-whitening cosmetics based on natural Chinese herbal medicines are green, safe, mild and skin-friendly, and are very popular. Chinese patent CN105168049A discloses a freckle-removing essence and its preparation m...
