The invention discloses a scalp oil control composition and a preparation method and application thereof, and belongs to the technical field of daily chemical product preparation, the scalp oil control composition comprises, by mass, 20-50 parts of a component A, 0.1-5 parts of menthol, 0.05-1 part of zinc gluconate, 0.3-1 part of a preservative, 0.1-0.6 part of a pH regulator and 42.4-79.45 parts of water, the component A is obtained by mixing a compound extract of white tea, cedar and spiraea ulmus with polyhydric alcohol, performing low-temperature centrifugal separation and filtering. According to the invention, the surfactant-containing water solvent is adopted to assist ultrasonic extraction of natural functional components of plants, so that the problem of abnormal secretion of scalp grease caused by solvent residue is avoided, no extraction solvent residue is realized, and the operation is simple; meanwhile, extracts of the white tea, the cedar and the spiraea inflorescens are reasonably matched and supplement with other auxiliary components to synergistically achieve the effects of regulating scalp grease secretion, inhibiting inflammatory factors and maintaining scalp micro-ecology, so that the scalp oil control effect is achieved, and the composition can be widely applied to scalp oil control daily chemical products.

The application provides an oral instant tablet containing Morinda citrifolia oil, which comprises the following components in parts by mass: Morinda citrifolia oil microemulsion 10 parts, carrier 30-40 parts, coating material 2-4 parts, and disintegrating agent 2-5 parts. The coating material is selected from Aeroperl and / or Sylysia; the carrier is selected from one or more of microcrystalline cellulose MCC PH101, microcrystalline cellulose MCC PH102, starch and lactose; and the disintegrating agent is selected from carboxymethyl starch sodium and / or low-substituted hydroxypropyl cellulose. The microemulsification technology is used to wrap the essential oil to reduce the volatilization of the essential oil; the microemulsion is made into a tablet to cover the acidity, increase the compliance of the public, and realize the form change of the Morinda citrifolia oil microemulsion from liquid to solid. The application studies and prepares the oral instant tablet containing Morinda citrifolia oil, which not only solves the inherent defects of traditional dosage forms, but also provides a more convenient taking mode compared with common tablets.

The invention provides a preservative as well as a preparation method and application thereof, and belongs to the technical field of blueberry preservation. The preservative disclosed by the invention is prepared from 0.03 to 0.06 part of basil essential oil, 0.01 to 0.03 part of citronella essential oil, 0.05 to 0.09 part of purple perilla essential oil, 0.05 to 0.10 part of thymol, 0.01 to 0.05 part of sweet osmanthus essential oil, 0.01 to 0.05 part of origanum vulgare essential oil, 0.02 to 0.04 part of cinnamyl aldehyde, 0.05 to 0.08 part of cysteine and 0.5 to 2.0 parts of ethanol. The preservative disclosed by the invention is used for carrying out preservative and fresh-keeping on blueberries, and can be used for remarkably reducing the rotting rate of the blueberries, delaying the aging of the blueberries and keeping the color and flavor of the blueberries.

The invention relates to a mud mask composition and a preparation method thereof. The mud mask composition comprises a phase A and a phase B, wherein the phase A comprises 15-40 parts of purified water, 10-30 parts of butanediol and 0.1-1 part of potassium hydroxide; a phase B: 2-10 parts of polydimethylsiloxane and 1-5 parts of stearic acid; a phase C: 5-20 parts of kaolin and 2-10 parts of black charcoal cocoa powder; and a phase D: 0.5-2 parts of cetyl ethyl hexanoate, 0.5-2 parts of hydroxyacetophenone, 2-5 parts of sodium cocoyl glutamate, 2-5 parts of supramolecular salicylic acid, 0.1-0.5 part of PCA zinc, 1-5 parts of a rosewood seed extract, 1-5 parts of a pinus densiflora leaf extract, 1-5 parts of a cinnamon bark extract and 1-5 parts of a film-forming agent. Compared with the prior art, according to the mechanism and characteristics of black and white head formation, the black and white head problem of facial skin is systematically solved by sequentially adopting four levels of pore dredging, source oil control, sterilization and bacteriostasis and pore repairing, the black and white head problem is prevented from being repeated, and the black and white head problem is thoroughly solved.
