Description
Technical Field
The invention relates to the technical field of daily chemical products, in particular to a plant-based perfume and a preparation method thereof, and further relates to a mosquito-repellent and bacteriostatic plant-based perfume and a preparation method thereof.
Background
Mosquito bites are a big problem in summer, and are troubled by the mosquito bites both outdoors and indoors. Meanwhile, the skin can be caused to have reactions such as red swelling, pain and itch, allergy and the like after being bitten by mosquitoes, and more importantly, the mosquitoes are the transmission media of various pathogenic bacteria, and various infectious diseases can be transmitted by the biting of the mosquitoes. Therefore, mosquito repellent products have high demand especially in summer. The mosquito repellent products in the current market mainly take floral water with mosquito repellent function, and mosquito repellent effect is achieved by adding mosquito repellent agents such as deet, anophelifuge and the like. However, as a product for repelling mosquitoes and relieving itching, the odor of toilet water is usually pungent, and the odor is not suitable for daily trips and office use.
With the social development and the improvement of living standard of people, the perfume products are widely used, but the existing perfume products pay more attention to smell and lasting fragrance and generally do not have good mosquito repelling and sterilizing functions. Meanwhile, the perfume product is usually added with chemical essence, which causes certain stimulation to the skin.
Chinese patent application 201310557271.2 discloses a preparation method of mosquito-repellent perfume containing natural plant essential oil, and the used natural raw materials comprise: herba nepenthes, herba schefflerae chinensis, flos Pelargonii Hortori, herba Menthae, folium Eucalypti Globueli, fructus Caricae, rhizoma et radix Valerianae, folium Artemisiae Argyi, herba Gynostemmatis, caulis Aristolochiae Tikouae, herba Trifolii Pratentis, radix Inulae, flos Matricariae Chamomillae, and Cotinus coggygria. The mosquito-repellent perfume provided by the invention adopts natural plant raw materials, does not contain a chemically synthesized mosquito repellent, can repel mosquitoes for more than 6 hours, has unique fragrance and does not stimulate the skin.
Chinese patent application CN201510534419.X discloses a rose fragrance skin-moistening refreshing mosquito-repellent perfume, which comprises the following components in parts by weight: 15-30 parts of essence, 2-10 parts of lily essential oil, 4-8 parts of hyaluronic acid, 3-15 parts of betaine, 3-15 parts of anophelifuge liquid, 5-15 parts of tsaoko amomum fruits, 5-15 parts of eucalyptus oil, 5-15 parts of angelica sinensis, 5-15 parts of rose extract, 5-15 parts of honeysuckle leaf juice, 5-15 parts of radix bupleuri decoction, 5-15 parts of semen plantaginis decoction, 5-15 parts of peach blossom extract, 10-25 parts of pear juice, 10-25 parts of jackfruit essential oil, 4-16 parts of elecampane, 4-16 parts of bergamot essential oil, 4-16 parts of electrolyzed water and the balance of distilled water. The mosquito repellent ester is still required to be added to achieve the mosquito repellent effect, and the essence is added to cause great irritation to skin.
Although the plant-based perfume is more nontoxic and healthy, the fragrance of the plant-based perfume has short duration and poor persistence, and is easy to generate precipitate substances in the storage process. In addition, the research on plant-based perfume is less at present, the selection range of the perfume is narrow, and more products with different high-grade perfumes are required to meet the public demand.
In view of the above, the invention provides the plant-based perfume, which has high-grade aroma for relieving emotion, has good mosquito repelling effect and sterilizing effect, meets the demand of mosquito repelling in summer, and further meets the demand of consumers. Meanwhile, the stability and the volatility persistence of the plant extract are improved, and the fragrance is retained and the storage time is long.

4. Persistence of fragrance
Please refer to 30 female volunteers, aged 18-40 years, without discomfort such as cold, healthy and unobstructed nasal cavity, without smoking, and without using tasty product during testing.
The tested groups are test toilet paper in which 1 drop of C0-C4 perfume is dripped, and the control group is test toilet paper in which 1 drop of purified water is dripped. Standing at room temperature for 2h, 4h, 8h, 12h, and 14h, and making evaluation (smelling or not smelling) by each volunteer smelling the fragrance of the test toilet paper. Wherein, the tested group and the control group need a circular sequence when smelling the volunteers, and the sequence can not be fixed.
M=(N1/30)×100%
Wherein M is the proportion of the number of people smelling the fragrance to the total number of people evaluated (M is more than 50% and M is more than N, namely the duration is judged to have the fragrance retaining effect), N1 is the number of people smelling the fragrance in each test article test, and the test results of the test articles C0, C1, C2, C3 and C4 respectively correspond to M0, M1, M2, M3 and M4. The ratio of the number of people smelling the fragrance in the control group to the total number of people to be evaluated is calculated by the same method and is counted as N. During the test, N is always 0. The variation curves of M0, M1, M2, M3 and M4 are shown in the attached figure 1. It can be seen that C1, C2, C3, C4 all had a fragrance retention of 8h, with C3 having a fragrance retention of 12 h.
According to the results of mosquito repellent effect, bacteriostasis rate and stability, lasting fragrance and the like, the C3 product has better comprehensive performance.
