The invention provides the use of at least one alkyl-phthalide or a plant extract comprising mainly said alkyl-phthalide for the topical cosmetic treatment of the skin and of the scalp, in particular an anti-dandruff treatment. According to the invention, a CO.sub.2 supercritical extract of Apium graveolens seeds consisting mainly of sedanenolide may be used.

The present invention is directed to hair care composition comprising from about 8 to about 17% of one or more surfactants; from about 0.01% to about 10% of one or more surfactant soluble antidandruff agents; from about 0.01% to about 5% of one or more polyacrylate or polyacrylamide based thickening polymer; from about 0.02-0.25% salicylate salts or acids; from about 0.02-0.25% benzoate salts or acids wherein there is a weight ratio of about 1:1 to 12.5:1 for the salicylate salts or acids to benzoate salts or acids.

A personal care composition comprising a surfactant-insoluble piroctone complex and a surfactant.

Disclosed is a topical composition comprising: (i) an antimicrobial active which is at least one of piroctone, caprylhydroxamic acid, benzohydroxamic acid, or piroctone olamine; and (ii) norbraylin. Also disclosed is a non-therapeutic method of providing topical antimicrobial benefit on a topical surface of a human or animal body comprising a step of applying a safe and effective amount of the topical composition.

Disclosed is a topical composition comprising: (i) an antimicrobial active which is at least one of piroctone, caprylhydroxamic acid, benzohydroxamic acid, or piroctone olamine; and (ii) Febrifugine. Also disclosed is a non-therapeutic method of providing topical antimicrobial benefit on a topical surface of a human or animal body comprising a step of applying a safe and effective amount of the topical composition.

A concentrated salicylic acid gel comprising salicylic acid and a stabilizer compound, wherein the salicylic acid comprises at least 30 wt % of the total weight of the gel.

A formulation for the treatment of hair, in particular for treatment of hair loss and dandruff, useful as a lotion and/or a spray. The formulation comprises at least dates, date seeds, and ethanol from fermented dates and date seeds.

The present invention is directed to a personal care composition comprising from about 10% to about 25% of one or more surfactants; from about 0.1% to 10% of sulfur; wherein the sulfur has a mean particle size (D50) of from about 5 μm to about 150 μm; from about 0.05% to about 10% of one or more stabilizing polymers; and from about 0.01% to about 4% of a suspending wax.

The invention relates to the use of a hydroperoxy alcohol-type compound, or a 1,2,4-trioxane compound thereof, as an antimicrobial agent, making it possible for it to be used in various applications and in particular as a preservative and/or to improve the antimicrobial properties of at least one preservative, to modulate the skin microbiota, in the treatment or prevention of diseases affecting the skin, the mucous membrane and/or skin appendages or even to cleanse, sanitise, disinfect and/or sterilise a surface other than the skin, skin appendages and mucous membranes, in particular a hard surface or a textile. It also relates to a composition comprising such a compound. In addition to its antimicrobial properties, the aforementioned compound has good safety and emollient properties, making it particularly suitable for cosmetic use.

The invention relates to the cosmetic use of at least one compounds according to the following formula (I), as an anti-dandruff agent or for preventing and/or treating scalp dandruff: where “sugar” denotes a monosaccharide residue chosen from rhamnose, xylose, fucose, mannose, lyxose, and arabinose; where R, substituting the anomeric oxygen in the sugar (represented by “O” in formula (I)), denotes a radical comprising 6 to 38 carbon atoms chosen from: —a linear or branched, saturated alkyl radical; —a linear or branched, alkenyl radical; said linear or branched saturated alkyl radical being optionally substituted by at least one OH and/or NH2 function; —if “sugar” denotes a mannose residue, R denotes a linear C6-C38 alkyl radical, substituted by at least one OH function or an NH2 function; and the salts and solvates and/or optical isomers thereof, alone or in a mixture, particularly racemic forms. The invention also relates to compounds according to formula (I), and cosmetic compositions containing same. ##STR00001##
