The invention provides an ectoparasiticidal formulation which comprises an ectoparasiticidal agent, preferably the pyrethroid permethrin, as the pesticidally-active ingredient, together with a crystallization inhibitor selected from the group consisting of alkyl-substituted pyrrolidones, and optionally, one or more organic solvents and/or co-solvents. Preferably, the crystallization inhibitor is N-octyl pyrrolidone, and the organic solvent, if present, preferably comprises diethylene glycol monoethyl ether. The ectoparasiticidal formulation surprisingly yields a significantly enhanced speed of kill. Methods for manufacturing the formulation, as well as methods for treating animals infested with ectoparasites, are also disclosed.

Anhydrous cosmetic compositions comprising hydrolyzed jojoba ester with increased short- and long-term thermal stability are disclosed. The compositions exhibit increased thermal stability of at least about 1&#xb0; C., preferably at least about 5&#xb0; C., and most preferably, at least about 10&#xb0; C., and optimally at least about 15&#xb0; C. The compositions provide excellent aesthetic and long-wear properties and are resistant to liquid syneresis and are useful in cosmetic and personal care formulations.
