Description

Lasting fragrance kit and application thereof

Technical Field

The invention relates to a balm product in the field of cosmetics, in particular to a set capable of lasting fragrance and application thereof.

Background

Research has shown that aromatic substances can improve the psychological and physiological state of humans. Products with desirable aromas will undoubtedly increase the appeal and competitiveness of the product. Therefore, the essence, spice or essential oil plays an important role in the industries of daily chemicals, furniture, construction, clothing and the like. For the daily chemical field, aromatic products occupy a large proportion, and sales data are rising year by year. The aromatic products for human body mainly comprise perfume and balm. Perfumes can be divided into three different forms, namely alcohol solutions, emulsions and slurries. Generally, the perfume is prepared from essence, spice or essential oil and a solvent. The balm product is mainly prepared by adding solid solvent or thickened liquid solvent into essence, spice or essential oil. And the essence, spice or essential oil has the characteristic of easy volatility. Is easy to volatilize in the using process, and causes the defect of short fragrance-retaining time. Therefore, for the evaluation of a fragrance product, the length of the fragrance retention time becomes one of the key indexes. How to improve the fragrance retention time of the perfume or balm products also becomes the research focus of attention of researchers in the industry.

At present, two main technical approaches for improving the fragrance retention time of essence, spice and essential oil are as follows:

firstly, the method comprises the following steps: and (4) packaging technology. The essence, spice or essential oil is wrapped in the material such as liposome, dextrin, modified starch, polyvinyl alcohol, silicon dioxide, polyacrylate, polyurethane, gelatin or chitosan by a physical mechanical method, a chemical synthesis method, a physical chemical method and the like, and the size of the material is controlled within a nanometer or micrometer scale. The inclusion is then added to the desired formulation. The essence wrapped by the microcapsules is convenient to add in different fields and different formulas, and the operation is relatively convenient. This approach is also the dominant technique employed by various large perfumery companies. However, the complicated previous wrapping process inevitably leads to a relatively high price. In addition, the slow release of the essence is controlled, and the fragrance retention time is enhanced to a certain extent. But does not solve the problem of better locking the microcapsules on the skin, so the persistence of the fragrance is still insufficient.

Secondly, the method comprises the following steps: the adsorption technology uses cellulose and other nano-fiber materials to adsorb the essence. And then added to the formulation. However, such adsorbent materials are difficult to use in a balm product. On the one hand, the additional cost is increased, and on the other hand, the addition amount of cellulose and the like in the balm is limited.

Therefore, there is a need in the art to develop a new technology, which can achieve lasting fragrance retention of essence, perfume or essential oil in a balm product without complicated wrapping technology or adding additional adsorbing material, thereby helping manufacturers develop balm products more simply, economically and conveniently.

Fatty acids are a class of compounds consisting of three elements, carbon, hydrogen and oxygen, and are the main components of neutral fat, phospholipid and glycolipid. Fatty acid metabolism fatty acid radicals can be further divided into the following according to the difference of carbon chain length: short chain fatty acids, also known as volatile fatty acids, having less than 6 carbon atoms in the carbon chain; medium chain fatty acid refers to fatty acid with carbon number of 6-12, and mainly contains octanoic acid (C8) and decanoic acid (C10); long chain fatty acids having a carbon chain with greater than 12 carbon atoms. In a preferred embodiment of the invention, the additive used is a medium-or long-chain fatty acid. In a preferred embodiment, a fatty acid having 8 to 30 carbon atoms is used. In a more preferred embodiment, a fatty acid having 10 to 26 carbon atoms is used. In a more preferred embodiment, a fatty acid having 12 to 22 carbon atoms is used. In a specific embodiment, fatty acids having 12, 14, 16, 18, 20, 22 carbon atoms are used.

Fatty acids can be classified into 3 groups, depending on the difference between saturated and unsaturated hydrocarbon chains, namely: saturated fatty acids, without unsaturated bonds on the carbon to hydrogen; monounsaturated fatty acids having one unsaturated bond in the hydrocarbon chain; polyunsaturated fatty acids having two or more unsaturated bonds in the carbon-hydrogen chain. Saturated, monounsaturated or polyunsaturated fatty acids may be used in the colloidal platinum composition of the invention.

The K value is actually a characteristic value related to the relative viscosity of the aqueous solution of PVP, which in turn is a physical quantity related to the molecular weight of the high polymer, and thus the K value can be used to characterize the average molecular weight of PVP. In general, the larger the K value, the higher the viscosity, and the stronger the adhesiveness.

In a specific embodiment, the composition comprises polyvinylpyrrolidone having a K value within the range of 28 to 34.

Test example 3:

the test method comprises the following steps: olfactive methods: 30 fragrance smelling persons are selected, and the group of fragrance smelling persons are screened by fragrance smelling experiments in advance. They can easily distinguish deionized water, 1% acetic acid by mass concentration and 1% beta-phenylethyl alcohol. The samples were placed in a constant temperature, constant humidity room. The tester entered the room 30 minutes earlier before each test. Firstly, the product of the preparation A is smeared on the required part of the skin, after the product of the preparation A is completely absorbed, the product of the preparation B is smeared on the required area, and the waiting time is 3-10 minutes. Then, the fragrance intensity at each time point was counted. The fragrance was good, the fragrance was weak, the fragrance was + + in the middle, and the fragrance was + + +.

Table 6: fragrance retention test for balsam

As can be seen from Table 6, in comparative sample 1, samples 2 to 5 all had excellent fragrance retention, samples 2 to 3 all had fragrance retention of 8 hours, and samples 4 to 5 had fragrance retention of 24 hours. From the comparison between samples 2-4, the viscosity of the vinyl polydimethylsiloxane has some effect on the final effect. The choice of a relatively low viscosity (10000cSt) or a high viscosity (180000cSt) is relatively disadvantageous for the slow release of the fragrance raw material (essence, fragrance or essential oil). The viscosity is moderate (60000cSt), good spreadability and film forming property can be maintained, and finally the slow release and fragrance retention time are longer. Whereas the addition of silica had a slight effect on fragrance retention at 8h by comparison of samples 4 and 5. Other time periods are not apparent.
