Problems solved by technology

At present, the flavors and fragrances that people use generally last for less than 100 days, and the stability of the active ingredients of flavors and fragrances is poor. There are differences in the aroma characteristics when the fragrance top fragrance evaporates. The volatilization of fragrance is easily affected by the ambient temperature and humidity, resulting in uneven volatilization of fragrance. After adding flavors and fragrances to other products, the fragrance is easy to change and deteriorate.

Embodiment 1

[0024] Embodiment 1: nanoscale jasmine essence

[0025] The preparation method is: 1) Take 20g of deionized water, add 2g of PEG-8 caprylic acid glyceride / polyglyceryl-6 dioleate, then add cetearyl ether-6 (and) stearyl alcohol / PEG-6 hard 5g of fatty acid ester, 1.0g of bis-imidazolidinyl urea, 1.0g of di-tert-butylcresol and stir well for later use; 2) Take another 20g of jasmine essence, add 5g of polyacrylic acid cross-linking resin, mix well, add to the water phase, and stir Complete the primary emulsification; 3) adjust each parameter of the high-pressure homogenizer: pressure 750kg / cm 2 , the time is 10 minutes, the number of times is 3, and the treatment is ready. After testing, the average particle size of flavor and fragrance is 81.90nm, and the uniform and long-lasting release of fragrance can reach 210 days (according to GB / T14454.2-93 standard).

Embodiment 2

[0026] Embodiment 2: nanoscale rose essence

[0027] The preparation method is: 1) Take 20g of deionized water, add cetyltrimethylammonium chloride / polyglyceryl-6 isostearate 2g, then add polyglyceryl-3 distearate / PEG- 75 stearate 5g, bis-imidazolidinyl urea 1.0g, di-tert-butylcresol 1.0g and stir evenly for later use; 2) Take another 20g of rose essence, add 5g of polyacrylic acid cross-linking resin, mix thoroughly, and add to the water phase , stirring to complete the primary emulsification; 3) adjust the parameters of the high-pressure homogenizer: pressure 950kg / cm 2 , the time is 10 minutes, and the number of times 3 is processed. After testing, the average particle size of flavor and fragrance is 81.2nm, and the uniform and long-lasting release of fragrance can reach 210 days (according to GB / T14454.2-93 standard).

Embodiment 3

[0028] Embodiment 3: nanoscale lemon essence

[0029] The preparation method is: 1) Take 20g of deionized water, add PEG-8 caprylic glyceride / octoxynol-112g, then add 5g of lanolin-25 and cetyl ether-25 / PEG-32 stearate , 1.0g of bis-imidazolidinyl urea, 1.0g of di-tert-butylcresol and stir well for later use; 2) Take another 20g of lemon flavor, add 5g of polyacrylic acid cross-linking resin, 0.2g of violet, mix well, add to the water phase, and stir to complete Colostrumization; 3) adjust the parameters of the high-pressure homogenizer: pressure 1050kg / cm 2 , the time is 10 minutes, the number of times is 3, and the treatment is ready. After testing, the average particle size of flavor and fragrance is 80.96nm, and the uniform and long-lasting release of fragrance can reach 210 days (according to GB / T 14454.2-93 standard).

Abstract

The invention relates to a nanometer grade essence perfume manufacturing method. The manufacturing material is mixed by perfume, surfactant, and cosurfactant, composite emulsifying agent, water, and option component in proportion. The option component includes thickener, antioxidant, stabilizer, antiseptic, and colorant. Its manufacturing method includes the following steps: adding oil phase into water phase to form start emulsifying; distributed processing; its parameters are as follows: room temperature low adjusting pressure is 550kg / cm2-2500kg / cm2; time is 2-100min; number of times are 1-10. The formed nanometer grade essence perfume has good retention capability, persistence, and stability. The retention time can reach 2-3 times of material retention time. Fragrance can release over 200 days. It can be extensively applied ton weaving, paper-making, printing, and building materials fields, and so on.

Description

(1) Technical field [0001] The invention relates to a preparation method of essence and fragrance, in particular to a preparation method of nano-scale essence and fragrance. (2) Background technology [0002] An excellent flavor and fragrance should have good persistence and retention, so that the fragrance can be released stably and slowly during a long period of use. Since flavors and fragrances are mostly organic compounds that are volatile and extremely unstable in chemical properties, such as sweet-scented osmanthus-flavored flavors, which are prepared in a certain proportion from 19 kinds of raw materials such as ionone and methyl ionone, and jasmine-flavored flavors are made of It is composed of 21 kinds of raw materials, and the addition amount of each is different. The ingredients are complex, and they are easy to evaporate or decompose and deteriorate during use and storage. The release period has become an urgent problem for manufacturers of flavors and fragrance...
