The invention concerns ionic compounds in which the anionic load has been delocalized. A compound disclosed by the invention is comprised of an amide or one of its salts, including an anionic portion combined with at least one cationic portion M
+m
in sufficient numbers to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO
+
, an ammonium —NH
4
+, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic portion matches the formula R
F
—SO
x
—N
−
Z, wherein R
F
is a perfluorinated group, x is 1 or 2, and Z is an electroattractive substituent. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.
The invention is directed to a cosmetic composition and the precursor thereof. The composition has solid agent and liquid agent, both of which are cosmetic benefit ingredients. The solubility of solid agents in liquid agents in the inventive compositions is enhanced in the presence of a tricyclodecane amide.
The present invention relates to an improved process for preparing 4-substituted resorcinol derivatives, and intermediate compounds useful in the preparation of such resorcinol derivatives.

Disclosed are sphingolipid-rucinol derivatives, which comprise sphingolipid selected from the group consisting of N-acetylphytosphigosine, N-acetylsphiganine and N-acetylsphingadiene, and rucinol, and compositions for skin external use containing the derivatives. The sphingolipid-rucinol derivatives and the compositions exhibit an improved skin whitening effect. Further, the derivatives and compositions show an improved solubility of sphingolipid and a decreased toxicity and, accordingly, have broad applications.
The present invention is directed to 4-cyclopentyl resorcinol monohydrate, its Form I polymorph, formulations containing at least one of these compounds, and their use to lighten skin.
