Abstract

The invention relates to the technical field of skin care products, in particular to bovine placenta cell exosome freeze-dried powder and a preparation method thereof. An excipient composed of mannitol, trehalose, glycine, glycerin, Tween, albumin and water is combined with the preparation technology, and the prepared bovine placenta cell exosome freeze-dried powder has good stability and biological activity and can be stored for a long time at normal temperature. Experiments show that the bovine placenta cell exosome still keeps good integrity and biological activity after being preserved at the normal temperature of 25 DEG C for 6 months, and is suitable for long-term preservation, transportation and application.

Description

technical field

[0001] The invention relates to the technical field of skin care products, in particular to a freeze-dried bovine placental cell exosome powder and a preparation method thereof. Background technique

[0002] Animal placenta contains a variety of biologically active substances such as proteins, amino acids, immunomodulatory peptides, mineral elements, vitamins, and various functional factors. These active substances have the functions of regulating immunity, anti-stress, and anti-oxidation. They are also used For a longer time and scope, for example, animal placenta products such as cattle and sheep have been included in the "Catalogue of Cosmetics Used Raw Materials", including hydrolyzed placenta (bovine) extract (HYDROLYZED PLACENTAL PROTEIN), animal placental protein (PLACENTAL PROTEIN) and so on.

[0003] The placenta is rich in various types of stem cells, and the exosomes secreted by it, a vesicle with a diameter of 30-150 nanometers, contain various ty...
