FIELD: chemical or physical processes.

SUBSTANCE: group of inventions relates to a method of producing molecularly imprinted polymer(s) or MIP molecules (odorant molecules) by polymerising a mixture: i) one or more polymerisation initiators (s) of formula (A): (A), as well as their optical and geometrical isomers and their salts with acids; wherein in formula (A): R₁, R₂, R₃ and R₄ denote a linear or branched (C₁-C₈) alkyl group; x and y are 1; EA and EA' are CN; ii) one or more functional monomers (s) selected from: functional monomers of formula (C1) below: , as well as their optical or geometrical isomers, and their salts of organic or mineral acids or bases, as well as solvates; wherein in formula (C1): p equals 0; R⁶ denotes a linear or branched (C₁-C₈) alkyl group; R'⁶ denotes a group selected from -C(X¹)-X²-Alk-N(H)-R_d, where Alk denotes a linear or branched (C₁-C₈) alkylene group, and R_d denotes a hydrogen atom; and X¹ and X² are oxygen; and functional monomers of formula (C2) below: PM-(A₂)_p-(B’)_q-G, as well as their optical or geometrical isomers, and their salts of organic or mineral acids or bases, as well as solvates; wherein in said formula (C2): PM denotes a polymerizable part PM1: PM1, A₂ denotes -CH₂- group, and in this case p equals 1; B' denotes group X¹ which is oxygen, in which case q equals 1; R⁶ denotes a hydrogen atom or a linear or branched (C₁-C₈) alkyl group; G represents a neutral or acidic group selected from i) amino N (R'')_2, wherein R'' represents a hydrogen atom, and v) (G3): , wherein R⁷ represents a hydrogen atom; X¹ and X² denote oxygen; iii) one or more crosslinking agents of formula (C4) below: (C4), wherein in formula (C4): R⁸ denotes a linear or branched (C₁-C₈) alkyl group; X¹ and X² denote an oxygen atom; W denotes a linear or branched trivalent (C₁-C₈) alkyl group; w equals 2; and iv) one or more pore-forming solvent (s) selected from C₁-C₈ alcohols; in the presence of v) one or more molecules (molecules) of a odorous substance selected from: conjugated amino acids of formula (T4) below: , wherein in formula (T4): R₂₃ denotes -X²-C(X¹)-R₂₅, where X¹ is oxygen, X² is N (R"), where R" is a hydrogen atom, and R₂₅ is a linear or branched (C₁-C₈) alkyl group; and R₂₄ denotes -C(X¹)-X²-R₂₅, where X¹ is oxygen, X² is N(R"), where R" is a hydrogen atom, and R₂₅ is a hydrogen atom; ALK denotes a linear or branched (C₁-C₈) alkylene group substituted with a group -C(X¹)-X²-R₂₅, where X¹ and X² are oxygen, and R₂₅ is a hydrogen atom, also relates to a molecularly imprinted polymer, or MIP, fragrant substance molecules, also relates to a cosmetic composition, containing one or more molecularly imprinted polymer(s), also relates to a cosmetic method of treating body keratin materials and/or a molecule(s) responsible for odors, and also relates to the cosmetic use of one or more molecularly imprinted polymer(s) or MIP, as a deodorant for trapping a molecule (molecules) of a odorous substance or a means for selectively trapping a molecule (molecules) of a fragrant substance of a human body and/or molecules (molecules), responsible for human body odor on the surface of keratin materials.

EFFECT: group of inventions enables to obtain deodorant/antiperspirant products for concealing skin disorders almost immediately and/or noticeable for use in the consumer, which practically do not leave stains or which are even free from visible stains on clothes, which is in contact with skin.
