Description

Kumquat essential oil hydrolat mask and preparation method thereof

Technical Field

The invention relates to the field of daily skin care cosmetics, and particularly relates to a kumquat essential oil hydrolat mask and a preparation method thereof.

Background

Kumquat (Kumquat), also known as Kumquat, cukul shell, luofu, milk orange and the like, is a good variety of Kumquat (fcragasifolia) seeds of Kumquat (Auran) of citrus subfamily (Rutaceae) and fortunella (fortunella swing), and is a common fruit used as both medicine and food. The kumquat fruit contains rich vitamin A, and can prevent pigmentation, improve skin luster and elasticity, slow aging, and prevent skin from loosening and wrinkling. Kumquat also contains vitamin P, which is an important nutrient for maintaining the health of blood vessels and can strengthen the elasticity of blood vessels. The kumquat peel contains abundant vitamin C, and has health care and beauty treatment effects. The kumquat flower is rich in aromatic factors, can sooth liver and regulate qi, and has slight relaxing effect on the central nervous system. Therefore, kumquat is a resource with great development potential.

Saffron is rich in carthamin, and has effects of nourishing blood, promoting blood circulation, increasing blood oxygen supply, improving blood microcirculation, and supplementing blood oxygen, water and nutrition of skin cells, so as to make skin more delicate, glossy and elastic. In addition, the effects of promoting blood circulation and removing blood stasis can accelerate skin metabolism, thereby relieving skin pigmentation.

The mask is a carrier of beauty care products, is applied on the face for beauty functions such as moisturizing, whitening, anti-aging and grease balancing, is a cosmetic which is widely and frequently used in the cosmetic industry nowadays, and is popular with consumers. However, most of the facial masks in the market lack core active ingredients or the concentration of active substances does not reach the standard, the using effect is good, and even part of the facial masks contain fluorescent agents, hormones and the like, which can cause adverse effects on the skin. The facial mask which takes pure natural aromatic plant essential oil as a main effect and an aromatic additive and does not use chemical components such as artificial spice, pigment, preservative and the like has the characteristics of natural plant essential oil, easy penetration and absorption and strong effect, can meet the idea of pursuing nature and harmony of people, can fully play the effects of protecting the skin and regulating the mind and body of the essential oil, and integrates multiple effects. Therefore, the safe and effective natural essential oil mask has good market prospect.

The pH value, heat resistance, cold resistance and centrifugal stability of the facial mask liquid were measured according to the general test method for national standard cosmetics, and the obtained results are shown in Table 3

TABLE 3 results of physical and chemical index measurements

In the table, "+" represents normal and "-" represents abnormal

(3) Moisture retention rate measurement

Placing cumquat essential oil hydrolat masks prepared in examples 1-6 and comparative examples 1-3 of the invention into weighted beakers respectively, placing the cumquat essential oil hydrolat masks uniformly attached to the walls, naturally drying the masks, weighing the masks after 0.5h, 1h, 2h and 4h respectively, and calculating the moisture retention rates of different mask solutions;

the moisture retention rate is defined as the weight of water after leaving/the weight of water before leaving × 100%, and the results are shown in the following 4:

table 4 determination of moisture retention of cumquat essential oil hydrolat mask (%)

As can be seen from the above table, firstly, all of the 9 facial mask liquids have a certain moisturizing effect, and the moisturizing effects of examples 1 to 6 are better than those of comparative examples 1 to 3, especially within a time period of 0.5 h. Secondly, in examples 1 to 6, the moisturizing rate was positively correlated with the increase of kumquat essential oil.

In contrast, in comparative example 1, in which no cumquat essential oil was added, in comparative example 2, and in comparative example 3, in which no cumquat essential oil and no hydrolat were added, the moisture retention rate decreased, and in comparative example 3, the effect was the worst.

(4) Clinical trial

100 facial mask skin protection enthusiasts are selected, all of the facial mask skin enthusiasts have skin problems of high skin allergy and excessive skin melanin deposition in different degrees, after the kumquat essential oil hydrolat facial masks prepared in the invention examples 1-14 and the comparative example 1 are randomly used, five items of the quality of the facial mask used, including smell, texture, comfort level, application degree and whitening effect, are evaluated, the full score of the facial mask is 10, the high score is better, and the result is shown in the following table 5

The specific use is as follows: the cumquat essential oil hydrosol facial mask prepared by the invention is applied to the face 3 times a week after the face is cleaned, and is cleaned after 10-15 minutes and continuously used for 3 months, and other skin care products are not used during the use period.

TABLE 5 clinical evaluation results (points) of the mask

And (4) analyzing evaluation results:

(1) and (3) quality evaluation score: examples 1 to 6 were from 40 minutes to 45 minutes. Comparative examples 1 to 3 were 21 to 38 points, indicating that the facial mask prepared by the present invention is good in quality. When the kumquat essential oil is not added in the comparative example 1, the clinical effect of the facial mask is reduced when the kumquat essential oil is not added in the comparative example 2 and when the kumquat essential oil and any hydrolat are not added in the comparative example 3, wherein the effect of the comparative example 3 is the worst, and the effect of the comparative example 2 is slightly better than that of the comparative examples 1 and 3, and the results show that: the cumquat essential oil has a remarkable effect on the quality of facial mask liquid, and the facial mask liquid prepared by blending the cumquat essential oil and the hydrolat can improve the quality and effect of the facial mask, so that the facial mask has better use experience and effect.

(2) Efficacy of cumquat essential oil: examples 1 to 6 with the addition of cumquat essential oil had whitening effect scores of 6 to 8 points for examples 1 to 6 and 7 and 9 points for comparative examples 1 and 3, respectively, as compared to comparative examples 1 and 3 without the addition of cumquat essential oil. The cumquat essential oil has a certain positive effect on whitening products.

(3) Comparing kumquat hydrolat, kumquat flower hydrolat and kumquat freeze-drying water: by comparing examples 1-6, the scores of moisturizing, texture and the like of the product are not greatly different by adding the cumquat hydrolat or cumquat lyophilized water, and the three can be replaced by combining practical conditions and cost.
