The invention provides a cosmetic product which has a good texture and allows full expression of the inherent functions of ceramide as an intercellular lipid, such as skin barrier function and hair protection effect, as well as nanoparticles for cosmetics and powder for cosmetics which may be used in the above cosmetic product, exhibit good skin barrier function and hair protection effect, and are easy to incorporate into the above cosmetic product. The cosmetic product, the nanoparticles, and the powder for cosmetics according to the present invention contain a polymer obtained by polymerization of a monomer material containing a glycerol(meth)acrylate monomer represented by the formula (1): n n n(R 1 : —H, —CH 3 ; R 2 : —(CH 2 )n-; n is an integer of 1 to 4). |
