Is solid perfume harmful to the body?

In our daily life, many people are discussing what perfume is. Everyone's understanding of perfume is not limited to this. The uses of perfume are quite wide. Generally, perfume includes many elements and many types. Some are liquid perfumes, and some are solid perfumes. Solid perfumes can emit a faint fragrance by themselves. The quality of the essence contained in it determines the quality of the perfume, so everyone is very worried about whether solid perfume is harmful to the body.

Main raw materials

Perfume is made by dissolving essence in ethanol solution (alcohol). Its raw materials are flavor, ethanol and water.

The essences and materials contained in perfume have a direct impact on its grade. The fragrance of high-end perfumes is mostly made of natural flower and fruit essential oils and animal spices, forming a blend of floral, fruity and animal scents that lasts long. The essences used in low-end perfumes are mostly made with artificial flavors. The denier content of the essences is generally around 5%. The scent is slightly inferior and the fragrance lasts for a short time. There are roughly the following types of perfume scents: light fragrance, grass fragrance, and floral fragrance. Aldehyde fragrance, floral fragrance, powdery fragrance, moss fragrance, orchid fragrance, and fruity fragrance. Oriental type; tobacco, leather fragrance. Fougere fragrance.

The water used to make perfume must be fresh distilled water or sterilized deionized water. The presence of microorganisms is not allowed. Ordinary tap water or natural water (such as tap water, spring water, etc.) must not be used. Microorganisms in the water will be killed by the added ethanol, but the precipitate formed will affect the aroma of the aromatic substances. Iron, steel and other substances are also not allowed because they can induce oxidation of unsaturated aromatic substances.

Therefore, production equipment, pipelines, and containers should avoid using iron and copper materials, and stainless steel products should be used. If there is no condition to obtain good quality water, it is necessary to add integrators or softeners such as sodium citrate and EDTA to inhibit metal ion pollution of water. It can also increase the anti-corrosion effect. The amount of softener used is about 0.02%-0.05%. It is more effective when used in combination with oxygen disruptors. The general dosage of antimicrobial agents (such as di-tert-butyl ether) is.

02Y.-0. 1%. It is also best to use deionized water for the final wash of the packaging bottle. This can remove all traces of metal ions to protect the aroma components, prevent metal-catalyzed oxidation, and stabilize the color and aroma.

Ethanol has a great influence on perfume and cannot have the slightest smell. Otherwise it will seriously damage the aroma. Generally, perfume uses 95% ethanol. Before use, it must be refined through separation, bleaching, and decolorization. In addition, a small amount of spices should be added to the wine in advance, and then it should be aged for a long time.

The aromatic tips used, such as secret incense balsam, tolu balsam, benzoin resin, etc., are added and are about. .1%; search for Baidang gum, oak moss gum, cyperus root oil, windproof root oil, etc., the maximum number of people added is about. .05 Brother. The most noble perfumes are often made from aged ethanol with natural animal flavors or vanilla beans.

Because the volatilization speed of fragrance molecules is very important to the durability of the perfume's aroma, fixatives are used to slow down the volatilization of fast-evaporating fragrances as much as possible so that all kinds of fragrances evaporate at about the same speed. Plant fixatives include Peruvian gum, balsam gum, benzoin, styrax frankincense, white walnut, vanilla oil, vetiver extract, and linalool; animal fixatives include incense, civet, kelp, and ambergris. Synthetic fixatives include siderocarp, xylene, benzyl benzoate, etc.

Homemade method

1. First, we choose a glass container, drop in a base oil and up to 3 essential oils, and mix them into a scent that you think is ok.

2. Take a small piece of natural beeswax, melt it in a microwave or steamer, and pour in the essential oil prepared previously. The ratio of natural beeswax to essential oil is 1:1. Use a clean wooden stick or spoon to mix it well.

3. Pour the mixed grease liquid into a delicate small box and wait for it to solidify naturally.

How to use

It is common sense to rub it on the pulse. It would be better to rub it on the inside of the elbows or the inside of the knees: because the skin temperature in these areas is high and they are frequently active, they will emit fragrance more efficiently. The inner side of the wrist is also a vein, so the moisture will disappear quickly because of its frequent contact with objects. It is certainly not as good as rubbing it on the inner side of the elbow and knee where there are pulses and which have appropriate external protection. There is no better place than these two places.
