The present invention relates to a hygienic protector (1), particularly for the collection and separation of human solid excrement, which is configured to be at least partially inserted into the opening (2) of a toilet bowl (3), or of another device for the collection of human excrement, and comprises a central portion (4) and a peripheral portion (5), where the central portion (4) defines a container body (6) for the collection and treatment of human solid excrement, and the peripheral portion (5) is configured to protrude externally with respect to the edge of the opening (2) of the toilet bowl (3). The central portion (4) and the peripheral portion (5) are provided in a water-soluble and biodegradable material. The container body (6) comprises an opening (7) that is shaped like the opening (2) of the toilet bowl (3). The peculiarity of the invention consists in that it comprises at least one anti-odor membrane (10, 11) that extends over the central portion (4), so as to close the opening (7) of the container body (6). The anti-odor membrane (10, 11) is provided in a material that is water-soluble, biodegradable and heat-sensitive, which is adapted to puncture upon contact with the solid excrement, substantially at the area of contact between the at least one anti-odor membrane (10, 11) and the solid excrement.
