The invention relates to liquid compositions for use with hair removal devices comprising a methathesized unsaturated polyol ester for improved lubrication.

The invention described herein includes a self-neutralizing amino acid-based cationic composition that contains an amino acid-based cationic ester, a nonionic amphiphile, and an anhydrous buffering agent. In an embodiment, the composition, when dispersed or dissolved in an aqueous solvent, provides a resultant solution/dispersion having a pH of greater than about 4. The amino acid-based cationic ester may be a reaction product of (i) an amino acid having a non-polar side chain, and an amine group that has been neutralized with an acid; with (ii) a long chain fatty alcohol. Also included within the scope of the invention are methods of preparing a self-neutralizing amino acid-based cationic composition, such method including combining an amino acid-based cationic ester, a nonionic amphiphile and an anhydrous buffering agent. The resulting composition is in an anhydrous solid form. Formulations containing the amino acid-based cationic ester and/or a composition that includes it, are also disclosed.

The present disclosure describes a razor cartridge including a housing having a front edge and a rear edge; shaving blades disposed between the front edge and the rear edge; and at least one shaving bar disposed in front of the blade(s) and/or rear of the blade(s) which includes a solid shaving aid composition that includes, relative to the total weight of the solid shaving aid composition: about 15 wt.-% to about 48 wt.-% of a soap base including of one or more fatty acid salts having from about 8 to about 24 carbon atoms and optionally one or more fatty acids having from about 8 to about 24 carbon atoms, at least about 35 wt.-% of one or more polyols including from ˜2 to ˜8 carbon atoms; the polyol selected from a group including glycerol, sorbitol, ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, methylpropane diol glycol.
