Embodiment 1

[0035] A fragrance submicron capsule with emulsification function is made of the following raw materials: 0.5 parts by weight of octyl alginate, 0.25 parts by weight of essence, and 0.5 parts by weight of calcium monohydrogen phosphate.

[0036] Concrete preparation method comprises the following steps:

[0037] (1) Add octyl alginate powder into deionized water, stir at room temperature until completely dissolved, and prepare a octyl alginate solution with a concentration of 0.5% by mass.

[0038] (2) Slowly add the essence dropwise into the alginic acid octylamide solution, stir and mix evenly at a constant temperature of 20°C, and then perform shear emulsification at 15000rpm for 13min to form a primary emulsion. (3) Pass the emulsion through a jet micromixer to obtain an emulsion with a smaller particle size and uniform distribution, receive it in the calcium monohydrogen phosphate suspension under magnetic stirring, and continue magnetic stirring for 3 hours at room tempe...

Embodiment 2

[0041] A fragrance submicron capsule with emulsifying function is made of the following raw materials: 0.8 parts by mass of octyl alginate, 0.4 parts by mass of essence, and 0.8 parts by mass of calcium monohydrogen phosphate.

[0042] Concrete preparation method comprises the following steps:

[0043] (1) Add octyl alginate powder into deionized water, stir at room temperature until completely dissolved, and prepare a octyl alginate solution with a concentration of 0.8% by mass.

[0044] (2) The essence was slowly added dropwise to the alginic acid octylamide solution, stirred and mixed evenly at a constant temperature of 20°C, and shear emulsified at 12000rpm for 10min to form a primary emulsion.

[0045] (3) Pass the emulsion through a jet micromixer to obtain an emulsion with smaller particle size and uniform distribution, receive it in the calcium monohydrogen phosphate suspension under magnetic stirring, and continue magnetic stirring for 4 hours at room temperature to c...

Embodiment 3

[0048] A fragrance submicron capsule with an emulsifying function is made of the following raw materials: 1 part by mass of octyl alginate, 0.5 part by mass of essence, and 1 part by mass of calcium monohydrogen phosphate.

[0049] Concrete preparation method comprises the following steps:

[0050](1) Add octyl alginate powder into deionized water, stir at room temperature until completely dissolved, and prepare a octyl alginate solution with a concentration of 1% by mass.

[0051] (2) The essence was slowly added dropwise to the alginic acid octylamide solution, stirred and mixed evenly at a constant temperature of 20°C, and shear emulsified at 10,000rpm for 5min to form a primary emulsion.

[0052] (3) Pass the emulsion through a jet micromixer to obtain an emulsion with smaller particle size and uniform distribution, receive it in the calcium monohydrogen phosphate suspension under magnetic stirring, and continue magnetic stirring for 5 hours at room temperature to carry ou...

Abstract

The invention provides a submicron fragrance capsule capable of emulsification. The capsule comprises a core material and a wall material, wherein the core material is a fragrance, and the wall material is made of caprylamide alginate. The invention further discloses a preparation method of the submicron fragrance capsule. The fragrance is wrapped in a submicron capsule, and the particle diameterof the prepared submicron fragrance capsule ranges from 0.1 mum to 0.6 mum; and a cosmetic emulsifier prepared from the submicron fragrance capsule is less irritating than emulsifiers prepared from surfactants according to the traditional method, eliminates harm to the skin caused by the fragrance, is safer and has a longer fragrance lasting period.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and relates to an emulsifier for wrapping essence, in particular to a submicron capsule of essence with emulsifying function. Background technique [0002] Pickering emulsion is a new type of emulsion that is stabilized by solid particles instead of traditional organic surfactants. Solid particles such as silica, alumina, montmorillonite, and titanium oxide are widely used in Pickering emulsions. Due to the non-compatibility and non-biodegradability of these particles, it greatly limits the use of such hard particles as emulsifiers in food and cosmetics. wide application in. Some compatible and biodegradable particle stabilizers (such as nano-chitin, cellulose nanocrystals, etc.) are widely used in Pickering emulsions. In the current product preparation process, the essence is directly added to the cosmetic emulsion. If the essence is in direct contact with the skin, it will irritate and damage th...
