A method of freeze-drying aqueous cosmetic compositions is provided, which produces the freeze-dried cosmetic in tablet form. The compositions contain amounts of trehalose and polyethylene glycol that render the tablets of the invention easy to handle, non-hygroscopic, and fast to dissolve.

The disclosure relates to composition and methods to treat dermatological diseases and disorders and to composition useful for treating acne.

A composition including a mixture of trigonella foenum-graecum extract and bentonite. The mixture is applicable in several technological fields, including the pharmacological, cosmetic, and veterinary field. Notably, the composition is useful in the treatment of a viral infection. The composition is synergistic in the sense that the mixture of trigonella foenum-graecum extract and bentonite has a higher efficiency than each of the components alone.

A mask substrate and a kit including the same are provided. The mask substrate includes a substrate layer; the substrate layer is prepared by freeze-drying a plant slice having a predetermined thickness under a predetermined condition. After the mask substrate is rehydrated with an infiltrating liquid, a surface of the mask substrate is able to be applied to the skin of an individual. In one of the aspects, the mask substrate may effectively absorb water or essence liquid through a natural fiber pore structure, which may release active substances contained in the substrate to improve the skin moisturizing effect.

The present invention provides a cosmetic shaped product: which is substantially formed with relatively low-molecular-weight hyaluronic acid or a water-soluble salt thereof having a high penetrability into the skin; which is easily soluble to water; and which has satisfactory handling properties, and a method for producing the cosmetic shaped product. There is provided a cosmetic shaped product being a sponge-like shaped body formed with at least one polyanionic polysaccharide of hyaluronic acid and a water-soluble salt thereof each having an average molecular weight of 30,000 or lower, the sponge-like shaped body having a bulk specific gravity of 5 to 500 mg/mL. This cosmetic shaped product can be produced by freeze-drying an aqueous solution having a content of the polyanionic polysaccharide of 0.5 to 30% by mass.

The present invention provides a method for preparing an high internal phase of pumpkin seed protein nanoparticles, including dissolving pumpkin seed protein powder in water and adjusting pH to approximately 8 to 11 to obtain a pumpkin seed protein solution; adding the pumpkin seed protein solution through a peristaltic pump into an ethanol solution with stirring for 4 hours to obtain a first solution; performing a centrifugation to the first solution and collecting precipitates; diluting the precipitates with water and performing a freeze-drying to obtain the pumpkin seed protein nanoparticles. The present invention first uses an anti-solvent method to prepare pumpkin seed protein nanoparticles, which have excellent emulsifying properties and can stabilize the high internal phase emulsion. In addition, the resulting pumpkin seed protein nanoparticles can stabilize the high internal phase emulsion independently without compounding with other substances.

Disclosed herein are improved methods for the synthesis of stannous pyrophosphate, as well as improved methods for the manufacture of oral care compositions comprising stannous pyrophosphate.

Disclosed herein are improved methods for the synthesis of stannous pyrophosphate, as well as improved methods for the manufacture of oral care compositions comprising stannous pyrophosphate.

A tablet-type cosmetic with improved handling properties is characterized by comprising (A) 30-91% by mass of trehalose and (B) 4.0-16% by mass of polyethylene glycol with a molecular weight of 11,000-25,000, and having a bulk specific gravity of 0.1-0.5 g/ml.

A method for culturing ginseng cell with high content of ginsenoside, including inducing ginseng cell line: after disinfected and sliced, ultrasonically treating old mountain ginseng, and culturing the old mountain ginseng in a culture medium; screening the ginseng cell line: choosing a variety of culture mediums and using hormones for cell separation and culture, selecting cell lines with better growth morphology and faster growth, and performing solid subculture and liquid suspension culture; optimizing conversion conditions: using acids to treat the chosen cell lines, and controlling the transformation temperature and transformation time, detecting ginsenosides Rg3 and Rh2 in the dried products, determining an optimal transformation condition according to the highest total amount; large-scale industrial production: according to the optimal transformation condition, performing the liquid suspension culture of the selected cell lines and scaling up the scale of culture to obtain large-scale industrial production of ginseng cell products.
