An objective of the invention is to provide a production method for a powdered solid cosmetic that, while having a texture similar to that in the case in which an elastic spherical powder is blended, also has excellent powder dispersibility and high impact resistance. The production method for a powdered solid cosmetic according to the present invention comprises a slurry preparation step of preparing a slurry by mixing a powder component and an oil-based component, as a binder, in a volatile solvent, wherein: the powder component includes a spherical powder, and the spherical powder contains (A) a non-elastic spherical powder having a crushing strength per particle of 30 MPa or higher; the oil-based component contains (B) a gel-type partially crosslinked organopolysiloxane polymer; the (A) non-elastic spherical powder constitutes 6% to 25% by mass of the powdered solid cosmetic; and 90% by mass or more of the spherical powder contained in the powder component is constituted by the (A) non-elastic spherical powder.

The present invention provides a solid personal care product comprising: a core layer containing a cleansing or conditioning component; and a skin layer containing a water-soluble or water-dispersible polymer. A solid personal care product produced according to the present invention solves the disadvantage that existing conventional solid cleansing agents or conditioning agents in powder, soap, or other flake form have of the powder scattering, as well as the problem of the cleansing power, conditioning efficacy, and fragrance-preserving property of such agents degrading. Moreover, the contents of the cleansing or conditioning component does not rub off onto the hands of a user even when the user holds the contents in the user's hands, and the shape of the product according to the present invention does not change even in places of high humidity. In addition, this solid personal care product is easy to use, store, and package, while retaining the same functions as those of conventional liquid cleansing and conditioning personal care products.

An oral hygiene composition which relates to oral hygiene compositions. More particularly, the present disclosure relates to a toothpaste which combines stannous fluoride and tea tree oil (Melaleuca). The composition prevents tooth decay and new cavity formation on enamel and dentin, reducing dentinal hypersensitivity when used regularly. The present disclosure helps prevent gum disease (Gingivitis) bad breath and improves oral hygiene and overall health.
