Problems solved by technology

However, the fragrance packaging technology of most fragrance companies focuses on the packaging of starch, melamine / formaldehyde resin or polyurea materials. These technologies have obvious shortcomings, such as large size and poor packaging effect, resulting in unsatisfactory fragrance retention.

preparation example Construction

[0045] Specifically, the preparation method of the essence capsule of an embodiment comprises the following steps:

[0046] Step S110: mixing the essence and isocyanate to form an oil phase.

[0047] Among them, the isocyanate is diisocyanate or polyisocyanate. In one embodiment, the isocyanate is selected from at least one of toluene diisocyanate, xylene diisocyanate, 4,4'-diphenylmethane diisocyanate and isophorone diisocyanate. It can be understood that the isocyanate is not limited to the above-mentioned substances, and can also be other isocyanates produced in the field, such as hexamethylene diisocyanate, hexamethylene diisocyanate and the like.

[0048] Specifically, the incense is selected from at least one of floral essential oils, fruity essential oils, woody essential oils and powdery essential oils. For example, the floral essential oil can be lavender essential oil. It can be understood that the essence is not limited to the types listed above, and it can also ...

Embodiment 1

[0091] The preparation process of the essence capsule of the present embodiment is specifically as follows:

[0092] (1) Mix 2.55g (0.011mol) of isophorone diisocyanate and 7.9mL of lavender essential oil to form an oil phase and set aside.

[0093] (2) Put the oil phase in step (1) into 100 mL of 1% polyvinyl alcohol aqueous solution by mass percentage, and homogenize at 9600 rpm for 5 min to form an emulsion.

[0094] (3) Add 100mL of 0.15% sodium alginate aqueous solution, 3.84g (0.0096mol) PEG400 and 0.22g catalyst dibutyltin dilaurate to the emulsion in sequence, and stir at room temperature for 50min to obtain the essence capsule prepolymer .

[0095](4) Add 0.11 g (0.95 mmol) of chain extender 1,6-hexamethylenediamine to the fragrance capsule prepolymer at a temperature of 70° C., react for 1 hour and then centrifuge to obtain lavender fragrance capsules.

[0096] Adopt optical microscope to observe the essence capsule prepared by the present embodiment, obtain as fol...

Embodiment 2

[0102] The preparation process of the essence capsule of the present embodiment is specifically as follows:

[0103] (1) Mix 2.55g of isophorone diisocyanate and 8.1mL of fresh floral essential oil evenly to form an oil phase and set aside.

[0104] (2) Put the oil phase in step (1) into 100 mL of a 1% polyvinyl alcohol aqueous solution by mass percent, and homogenize at a speed of 9600 rpm for 5 min to form an emulsion.

[0105] (3) Add 100 mL of 0.15% aqueous sodium alginate solution, 3.84 g of PEG400 and 0.22 g of catalyst dibutyltin dilaurate to the emulsion in sequence, and stir at room temperature for 50 min to obtain the essence capsule prepolymer.

[0106] (3) Add 0.11 g of chain extender catechol (0.001 mol) to the fragrance capsule prepolymer at a temperature of 70° C., react for 1 hour and then centrifuge to obtain fresh floral fragrance capsules.

[0107] Adopt optical microscope to observe the essence capsule prepared by the present embodiment, obtain as follows ...

Abstract

The invention relates to an essence capsule and a preparation method thereof and wash supplies. The preparation method of the essence capsule comprises the following steps: mixing the essence and isocyanate to form an oil phase; mixing the oil phase with an aqueous solution containing a first surfactant, and carrying out homogenization treatment at a rotating speed of 6000 rpm-15000 rpm for 1 min-10 min to form an emulsion; adding an aqueous solution containing a second surfactant and a water-soluble polymer into the emulsion, carrying out reaction on the water-soluble polymer and isocyanate, and thus preparing the essence capsule, wherein the water-soluble polymer is polyamine or polyalcohol. According to the preparation method of the essence capsule, the nanoscale essence capsule can be obtained, and the fragrance retention time of the essence capsule used in wash supplies is prolonged.

Description

technical field [0001] The invention relates to the field of daily chemical care and care, in particular to a fragrance capsule, a preparation method thereof and a care product. Background technique [0002] In recent years, the high-end new products in China's cleaning and care market have grown rapidly. Consumers' demands for cleaning and care products are no longer effective cleaning, but have higher requirements for the functionality of cleaning and care products, such as no additives, green and natural, etc. At present, aromatherapy is the new trend with the most development potential in recent years. Although there are a variety of fragrance cleaning products that claim to have long-lasting fragrance, the fragrance usually lasts between 24h and 48h, which cannot really last for a long time. [0003] Microcapsule technology has been widely used in daily chemical, pharmaceutical, food and other fields, especially in the daily chemical industry, the quality of traditiona...
