Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
The milky perfume of the present invention includes transparent glass and liquid perfume, and the liquid perfume is set inside the transparent glass bottle. The liquid perfume comprises the following components: essence, ethanol, deionized water, ethylene diamine tetraacetic acid disodium, butylated hydroxytoluene and styrene acrylate copolymer. The texture of the mixture liquid obtained by mixing ethanol, deionized water and styrene acrylate copolymer has a very thick state, especially in the case of observation through a clear glass bottle, and enables the resulting liquid perfume to be improved in a continuous stable state.
The invention is further described below by way of examples.
Example 1:
this example was prepared using the following steps:
step 1: detecting the used raw materials;
step 2: weighing qualified raw materials according to a formula, rechecking and then feeding;
and step 3: adding 3g of essence, 70g of ethanol, 30g of deionized water, 0.03g of disodium ethylenediamine tetraacetic acid and 0.05g of butylated hydroxytoluene at normal temperature, and mixing and stirring uniformly to obtain a liquid perfume mixture;
and 4, step 4: uniformly stirring the mixture obtained in the step 3, and then aging for 24 hours to obtain an aged mixture;
and 5: freezing the aged mixture at-5 deg.C, and vacuum filtering;
step 6: returning to normal temperature for inspection after the suction filtration is finished;
and 7: and after the liquid perfume is qualified, adding the liquid perfume into a transparent container.
Example 2:
this example was prepared using the following steps:
step 1: detecting the used raw materials;
step 2: weighing qualified raw materials according to a formula, rechecking and then feeding;
and step 3: adding 3g of essence, 70g of ethanol, 30g of deionized water, 0.03g of disodium ethylenediamine tetraacetic acid, 0.05g of butylated hydroxytoluene and 0.1g of styrene acrylate copolymer at normal temperature, and mixing and stirring uniformly to obtain a liquid perfume mixture;
and 4, step 4: uniformly stirring the mixture obtained in the step 3, and then aging for 24 hours to obtain an aged mixture;
and 5: freezing the aged mixture at-5 deg.C, and vacuum filtering;
step 6: returning to normal temperature for inspection after the suction filtration is finished;
and 7: and after the liquid perfume is qualified, adding the liquid perfume into a transparent container.
Example 3:
this example was prepared using the following steps:
step 1: detecting the used raw materials;
step 2: weighing qualified raw materials according to a formula, rechecking and then feeding;
and step 3: adding 3g of essence, 70g of ethanol, 30g of deionized water, 0.03g of disodium ethylenediamine tetraacetic acid, 0.05g of butylated hydroxytoluene and 0.2g of styrene acrylate copolymer at normal temperature, and mixing and stirring uniformly to obtain a liquid perfume mixture;
and 4, step 4: uniformly stirring the mixture obtained in the step 3, and then aging for 24 hours to obtain an aged mixture;
and 5: freezing the aged mixture at-5 deg.C, and vacuum filtering;
step 6: returning to normal temperature for inspection after the suction filtration is finished;
and 7: and after the liquid perfume is qualified, adding the liquid perfume into a transparent container.
Example 4:
this example was prepared using the following steps:
step 1: detecting the used raw materials;
step 2: weighing qualified raw materials according to a formula, rechecking and then feeding;
and step 3: adding 3g of essence, 70g of ethanol, 30g of deionized water, 0.03g of disodium ethylenediamine tetraacetic acid, 0.05g of butylated hydroxytoluene and 0.3g of styrene acrylate copolymer at normal temperature, and mixing and stirring uniformly to obtain a liquid perfume mixture;
and 4, step 4: uniformly stirring the mixture obtained in the step 3, and then aging for 24 hours to obtain an aged mixture;
and 5: freezing the aged mixture at-5 deg.C, and vacuum filtering;
step 6: returning to normal temperature for inspection after the suction filtration is finished;
and 7: and after the liquid perfume is qualified, adding the liquid perfume into a transparent container.
The difference between the 4 examples is whether there is a styrene acrylate copolymer and the styrene acrylate copolymer is present in different amounts, and the perfume model with the styrene acrylate copolymer is visually thicker and heavier, and the perfume is thicker and heavier when the styrene acrylate copolymer is present in a higher amount.
The milky perfume prepared in the 4 examples above was tested.
The test method comprises the following steps: the perfume sample plates obtained in 4 embodiments are sprayed on the wrists of office workers in a daily working environment, testers do not know each other and avoid communication, the fragrance of the wrists is smelled again every 30 minutes until the fragrance is completely volatilized, and the final fragrance remaining time is recorded.
It is known that styrene acrylate copolymers can also affect the length of perfume stay and the skin feel, the higher the styrene acrylate copolymer content the longer the perfume stay and the more sticky the skin feel.
Example 5:
this example was prepared using the following steps:
step 1: detecting the used raw materials;
step 2: weighing qualified raw materials according to a formula, rechecking and then feeding;
and step 3: adding 15g of essence, 60g of ethanol, 25g of deionized water, 0.03g of disodium ethylenediamine tetraacetic acid, 0.05g of butylated hydroxytoluene and 0.1g of styrene acrylate copolymer at normal temperature, and mixing and stirring uniformly to obtain a liquid perfume mixture;
and 4, step 4: uniformly stirring the mixture obtained in the step 3, and then aging for 24 hours to obtain an aged mixture;
and 5: freezing the aged mixture at-5 deg.C, and vacuum filtering;
step 6: returning to normal temperature for inspection after the suction filtration is finished;
and 7: and after the liquid perfume is qualified, adding the liquid perfume into a transparent container.
The difference between the embodiment 5 and the embodiment 2 is that the proportion of the essence, the ethanol and the deionized water is adjusted, the content of the essence is increased, and the content of the ethanol and the deionized water is reduced, because the proportion of the styrene acrylate copolymer to the ethanol and the deionized water is high, the texture of the perfume is slightly thicker and heavier, the fragrance-retaining time of the perfume is slightly increased, the skin-feel viscosity is slightly increased, the proportion of the essence to the ethanol and the deionized water is high, and the fragrance of the perfume is stronger.
The texture, the fragrance-retaining duration and the skin feeling of the perfume are influenced by the proportion of ethanol, deionized water and styrene acrylate copolymer, and the perfume effect of the example 2 is finally seen at present.
As described above, the present invention can be preferably applied to practical production. The above-mentioned embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, i.e., the present invention is claimed in the appended claims with all equivalent variations and modifications.
