Embodiment 1

[0044] A preparation method of rose essential oil microcapsules, the concrete steps are:

[0045] Step 1): Dissolve 10.00g of β-cyclodextrin in 80mL of deionized water to obtain an aqueous solution of β-cyclodextrin, stir it in a water bath at 80°C to dissolve it, and obtain an aqueous solution of β-cyclodextrin, cool to 50°C and keep it warm spare;

[0046] Step 2): dissolving 2 g of rose essential oil in an organic solvent to obtain a rose essential oil solution; the organic solvent is absolute ethanol, and the volume ratio of rose essential oil to absolute ethanol is 1:20;

[0047] Step 3): Add the obtained rose essential oil solution into the β-cyclodextrin aqueous solution drop by drop at a uniform speed, and stir while adding, the β-cyclodextrin contained in the β-cyclodextrin aqueous solution and the rose essential oil solution contained The mass ratio of rose essential oil is 5:1, and the reaction solution is taken out after sealing and embedding in the dark at 50°C f...

Embodiment 2

[0060] Embodiment 2 (sustained release, stability experiment)

[0061] The rose essential oil microcapsules, the test of the slow-release effect under exposure to the air, the specific data of the time and the quality of the fragrance change are as follows figure 2 shown. The experimental results can prove that the overall particle size uniformity of the rose essence microcapsules is high, the mechanical strength is good, and the stability is strong.

Embodiment 3-5

[0063] A shampoo containing rose essential oil microcapsules, calculated by mass percentage, its composition and content are as follows:

[0064] Table 1 Rose-flavored shampoo formula table

[0065]

[0066]

[0067] The preparation method of the above-mentioned shampoo containing rose essential oil microcapsules is:

[0068] 1) Weigh the amount of each component, first add deionized water into the reaction kettle, stir and heat up to 60°C;

[0069] 2) Add preservatives and pearlescent agents to the deionized water in the reaction kettle in step 1), stir and dissolve, and prepare JR-400 aqueous solution (0.1% JR-400 and 9.9% water);

[0070] 3) Add AES, 6501, ammonium oxide and JR-400 aqueous solution to the reactor in step 2) and stir to dissolve;

[0071] 4) Finally add menthol to the reaction kettle in step 3), stir and dissolve, add citric acid to adjust the pH value of the solution to 5.5-6;

[0072] 5) Decrease the reaction kettle to room temperature, add rose e...

Abstract

The invention provides a shampoo comprising a rose essential oil microcapsule and a preparation method thereof. The shampoo comprising the rose essential oil microcapsule consists of the following components by weight percent: 25 to 35 percent of surfactants, 0.5 to 1.2 percent of pearling agents, 0.3 to 0.8 percent of pH adjusting agents, 0.03 to 3 percent of preservatives, 0.04 to 1 percent of traditional Chinese medicine, 0.01 percent of pigments, 1 to 1.5 percent of rose essential oil microcapsules, and the balance of deionized water. The rose essential oil is embedded to be added into theshampoo, so that the shampoo product has the rose fragrance, is cool and comfortable to use, and has a bacteriostatic effect.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and relates to a hair shampoo, in particular to a traditional Chinese medicine type hair shampoo containing rose essential oil microcapsules and a preparation method thereof. Background technique [0002] Essential oils are volatile oils, and some components will volatilize at room temperature or below room temperature, resulting in poor stability and short fragrance retention time, which affects the quality of the product and greatly limits its application. Using microencapsulation technology to embed essential oils is a research hotspot in recent years. Through microencapsulation, the volatilization of the essential oil is suppressed due to the sealing effect of the capsule wall, and the aroma remains intact, thereby prolonging the storage time of the essential oil and improving the stability of use. Therefore, it is necessary to carry out research on microencapsulation embedding technology of r...
