The invention provides tranexamic acid-glutathione-containing compound emulsifiable paste and a preparation method thereof.W1 / O / W double emulsion phase structural design is adopted, reduced glutathione is encapsulated in an acidic inner water core, an oil phase is stabilized through hydrogenated lecithin and sorbitan sesquioleate, an outer water phase contains tranexamic acid, a layered gel network is constructed, and the tranexamic acid-glutathione-containing compound emulsifiable paste is prepared. A submicron dispersion system with the particle size D50 of 0.30-0.80 microns, the polydispersity index of 0.15-0.25 and the viscosity of 2.0-8.0 Pa seconds is realized, the encapsulation efficiency of glutathione is not lower than 70%, the oxygen content of a head space is not higher than 1.0%, and the encapsulation efficiency of glutathione is not lower than 70%. The three technical contradictions of coupling conflict between a high-yield viscoelastic structure and low-shear damage kernel integrity, coexistence of fresh and cool low-viscosity skin feeling and high-barrier anti-oxidation and anti-leakage and opposite low-surface-activity sensitive skin compatibility and submicron low-PDI dispersion stability are solved; the traditional Chinese medicine composition has wide application values of improving skin color unevenness, fading color spots, brightening skin color, soothing and repairing.

The invention discloses a water-in-oil type moisturizing rod composition and a preparation method and application thereof, the water-in-oil type moisturizing rod composition comprises an oil phase and a water phase, the oil phase comprises wax, a suspending agent, grease, an emulsifier and a first functional active matter, and the wax comprises synthetic wax and selective pure ozocerite and / or microcrystalline wax; the emulsifying agent is prepared from lauryl PEG (Polyethylene Glycol)-8 polydimethylsiloxane and / or cetyl PEG / PPG-10 / 1 polydimethylsiloxane, a polydimethylsiloxane / polydimethylsiloxane PEG-10 / 15 cross-linked polymer and / or sorbitan sesquioleate; the water phase comprises alcohol, salt, a second functional active matter and water; the preparation method comprises the following steps: respectively preparing an oil phase and a water phase, adding the water phase into the oil phase, homogenizing, filling and forming. The novel moisturizing rod with the W / O dosage form has a refreshing skin feeling, is beneficial to skin health, and has good formability, good storage stability and satisfactory sensory characteristics.

The present invention provides a cosmetic capable of imparting a moist feeling immediately after the cosmetic is applied and suppressing stickiness after application. A cosmetic according to the present invention comprises: (A) a glycine derivative; (B) at least one hydrophilic surfactant selected from the group consisting of polyoxyethylene hydrogenated castor oils and polyoxyethylene phytosterols; (C) at least one lipophilic surfactant selected from the group consisting of polyglyceryl diisostearate, sorbitan sesquiisostearate, and sorbitan sesquioleate; (D) an oil component; and (E) water.

The application provides a tranexamic acid-glutathione compound cream and a preparation method thereof, adopts a W1 / O / W double emulsion phase structure design, encapsulates reduced glutathione in an acidic inner water core, stabilizes an oil phase by using hydrogenated lecithin and sorbitan sesquioleate, and constructs a lamellar gel network in an outer water phase containing tranexamic acid, so as to realize a sub-micron dispersion system with a particle size D50 of 0.30-0.80 microns, a polydispersity index of 0.15-0.25 and a viscosity of 2.0-8.0 Pa seconds, the encapsulation rate of glutathione is not less than 70%, and the headspace oxygen content is not higher than 1.0%, three technical contradictions of a high yield viscoelastic structure and a low shear damage inner core integrity coupling conflict, a smooth low skin feeling and a high barrier anti-oxidation and anti-leakage coexistence problem and a low surface activity sensitive skin compatibility and a sub-micron low PDI dispersion stability are solved, and the application has wide application values of improving uneven skin color, lightening color spots, brightening skin color and soothing and repairing.

The invention relates to the technical field of sunscreen cream, in particular to children sunscreen cream and a preparation method thereof.The preparation method includes the steps that glyceryl stearate, sorbitan sesquioleate, tocopherol and simmondsia chinensis seed oil are put into a reactor and stirred to react, and a phase A is obtained; isoamyl laurate, glycerin, sodium hyaluronate, xanthan gum and deionized water are put into the reactor and stirred for a reaction, and a phase B is obtained; and fully mixing the phase A, the phase B, the aloe leaf juice, the coated sun-screening agent and the slow-release mosquito repellent to prepare the sun-screening cream for children. According to the sun cream disclosed by the invention, the coated sun-screening agent and the slow-release mosquito repellent are used in a combined manner, so that the efficient, non-irritant and safe sun-screening effect of the sun cream for children and the long-acting mosquito repellent effect are realized.
