Description

Technical Field

[0001] The invention relates to the field of daily chemicals, in particular to a colorful mosquito repellent perfume combining a decolorizable dye with a mosquito repellent component and a preparation method thereof. Background Art

[0002] In modern life, with the improvement of people's living standards and the pursuit of quality of life, perfume has become one of the cosmetics used in daily life. It can not only enhance personal temperament, but also has a certain emotional expression function. There are many kinds of perfume products on the market, and most colorful perfumes are cleverly designed to echo specific themes and emotional atmospheres. For example, girl fragrances often use pink tones (such as Lancome Miracle), green fragrance perfumes prefer green (such as Balmain Green Wind, Chanel No. 19), marine fragrance perfumes tend to be blue (such as Bulgari Water Energy), and floral fragrance perfumes may use red (such as Berlin Girl), pink (such as Suzhou Peony) or purple (such as Light Rhyme). However, the pigments used in traditional colored perfumes are non-fading pigments. Even if the colors are designed to be elegant, it is inevitable that they will leave difficult-to-remove marks on clothes or skin during use, affecting the user's wearing beauty and personal hygiene, especially when used on light-colored clothes. This defect undoubtedly limits the free use of colored perfumes, especially in formal occasions or outdoor activities where clothes need to be kept clean. In addition, with the increasing popularity of outdoor leisure activities, mosquito bites have become an important factor affecting the comfort and safety of outdoor activities. The existing mosquito repellent products on the market are in various forms, from sprays, pastes to bracelets, but these products are often incompatible with perfumes. Users have to face the inconvenience of carrying multiple products, which increases the burden and complexity of travel. Especially for modern consumers who pursue a simple lifestyle, this incompatibility between products is obviously a pain point that needs to be solved urgently.

[0003] There are many perfume formulas disclosed in the prior art, such as CN201710843588.0, CN201811283281.0 and CN201711462458.9, etc. They have their own characteristics, but none of them involve the combination of color and fading technology. At the same time, although CN202310310962.6 involves a colored mosquito repellent composition, its focus is on the hydrogel system and the long-lasting moisturizing mosquito repellent effect, and does not involve the color design and fading characteristics of the perfume.

[0004] The present invention proposes a colorful mosquito repellent perfume that combines beautiful colors, mosquito repellent function and easy fading characteristics, and a preparation method thereof. By using a specific proportion of natural plant essential oils as mosquito repellent ingredients and combining innovative fading dye technology, the present invention not only solves the problem of traditional colored perfumes that easily leave marks, but also cleverly integrates the mosquito repellent function, meeting the user's dual needs for outdoor protection and personalized expression while enjoying the pleasure brought by the perfume, achieving a major breakthrough in product functions and a significant increase in market value. Summary of the invention

[0005] The invention aims to provide a colorful mosquito repellent perfume and a preparation method thereof, wherein the perfume can achieve the effect of rapid fading when in contact with water while maintaining good fragrance and mosquito repellent effect.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A colorful mosquito repellent perfume comprises the following components, calculated by mass percentage: 5% to 20% of a perfume base (including alcohol, water and spices); 0.5% to 5% of a mosquito repellent ingredient; 0.01% to 0.1% of a decolorizable dye; 0.1% to 1% of a color developing aid; 0.8% of an auxiliary ingredient; and the balance of deionized water.

[0007] As a preferred embodiment, the components of the colorful mosquito repellent perfume are, by mass percentage, 10% to 15% of perfume base; 1% to 3% of mosquito repellent ingredients; 0.05% of decolorizable dye; 0.5% of color development aid; 0.8% of auxiliary ingredients; and the balance of deionized water.

[0008] The mosquito repellent component can be selected from one or more natural plant essential oils such as lemon eucalyptus oil, citronella oil, lavender oil, geranium oil, etc., so as to ensure the mosquito repellent effect while reducing the stimulation to the human body.

[0009] The decolorizable dye can be red ck-16, yellow LBC-71, green LBC-25, etc., ensuring that it can fade quickly after encountering water vapor and is harmless to human skin.

[0010] The color development auxiliary agent can be selected from oxalic acid, salicylic acid or their derivatives to optimize the color development and fading process of the dye, and maintain the bright color of the perfume and the rapidity of fading.

[0011] The auxiliary ingredients include pH adjusters (such as sodium hydroxide solution), stabilizers (such as xanthan gum), preservatives, etc.

[0012] A method for preparing a colorful mosquito repellent perfume comprises the following steps: 1) Prepare the perfume base by mixing alcohol, water and selected spices to ensure the scent is harmonious.

[0013] 2) Add mosquito repellent ingredients into the perfume base in proportion and stir evenly.

[0014] 3) Add the predetermined proportion of decolorizable dye and continue stirring until completely dissolved.

[0015] 4) Add color development aids to ensure that the dye is stable and easy to fade.

[0016] 5) Add auxiliary ingredients such as pH adjusters, stabilizers, preservatives, etc.

[0017] 6) Add the remaining amount of deionized water, stir thoroughly and filter to remove impurities to obtain the colorful mosquito repellent perfume.

[0018] Compared with the prior art, the invention has the following beneficial effects: the colorful mosquito repellent perfume prepared by the invention is not only bright in color and pleasant in fragrance, but also has a highly efficient mosquito repellent function, especially quickly fades after encountering water vapor, which not only meets consumers' dual pursuit of beauty and practicality, but also embodies the concepts of environmental protection and innovation, and has broad market prospects.
