The present invention relates to a low-skin irritating deodorant composition. The composition comprises an effective amount of an active ingredient comprising hexamine, derivatives thereof, or a combination thereof for reducing, inhibiting or suppressing development of malodour from a body part; a buffer system for substantially neutralising topical acidity of the body part; and an anti-irritating agent in an effective amount, wherein the anti-irritating agent comprises one or more botanically derived compounds selected from a group consisting of flavonoids, alkaloids, iridoids, terpenes, phenols, or a combination thereof.

This invention is a novel method of manufacture for hand-sanitizing lotions that retains the added benefits of prolonged effectiveness while avoiding demulsification as well as the resulting product. The invention presents a novel, more simplified process comprising a lower cooking temperature and an optimized ingredient addition protocol, designed for product stability and ingredient integrity.

Nanoemulsions and a method for making the same are described. The nanoemulsions comprise a skin benefit agent in the water phase and they are made from two macroemulsions that have non-identical pH values.

A hair treatment compositions including about 20 wt. % or more of a polyol; about 5 wt. % to about 50 wt. % of a monoalcohol having 1 to 10 carbons; about 0.1 to about 5 wt. % of silicone; about 0.1 to about 10 wt. % of a cationic polymer; about 0.1 to about 10 wt. % of a cationic surfactant; about 0.1 to about 15 wt. % of a fatty alcohol; and about 10 wt. % or less of water, wherein all percentages by weight are based on the total weight of the hair treatment composition.

The invention relates to a method of depositing a substance onto a substrate (6), comprising: —providing a substrate (6) at a distance from a conducting spraying nozzle (1), said spaying nozzle (1) having an outlet (2); —providing a liquid composition containing the substance to the spraying nozzle (1); —generating electrically charged liquid droplets from the liquid composition between the outlet (2) of the spraying nozzle (1) and the substrate (6), by providing compressed gas around the liquid composition flowing out of the outlet (2) of the spraying nozzle (1) and by providing an electric field downstream of the outlet (2) of the spraying nozzle (1); and collecting the generated liquid droplets on the substrate (6). The invention also relates to an installation for carrying out this method.

The present invention is in the field of personal care compositions, in particular compositions comprising antiperspirant actives. The present invention more particularly relates to compositions which do not contain the conventional and well established aluminium based actives, yet exhibit similar efficacy. This is achieved through use of an active which is a complex of a zinc salt with a β amino acid in an anhydrous carrier comprising a specific mixture of ethanol and a C.sub.2 to C.sub.4 glycol.

Present disclosure relates to a solvent-free method of encapsulating a hydrophobic active in personal care, hydrophobic active in crop protection or a hydrophobic active pharmaceutical ingredient (API) in polymeric nanoparticles. The method includes mixing the hydrophobic active in a polymer melt, wherein the polymer melt comprises a melt of a block co-polymer, wherein the polymer melt acts as a solvent for the hydrophobic active. The method further includes maintaining the polymer melt in water for sufficient time to allow self-assembly of the block co-polymer to encapsulate the hydrophobic active therein.

A hair care composition is disclosed comprising a salt of acyl glycinate, an ethoxylated alkyl sulfate anionic surfactant having a formula R.sup.2O(CH.sub.2CH.sub.2O).sub.nSO.sub.3M, wherein R.sup.2 is an alkyl or alkenyl group having from 8 to 18 carbon atoms; M is a solubilising cation comprising sodium, potassium, ammonium, substituted ammonium or mixtures thereof; n is the degree of ethoxylation of from 0.5 to 3; and an anti-dandruff agent selected from piroctone olamine, azole based anti-fungal agents and mixtures thereof; wherein the composition comprises the salt of acyl glycinate and the ethoxylated alkyl sulfate anionic surfactant in a weight ratio of from 1:10 to 1:1.

A calcium phosphate-based core-shell structured material, a method for preparing the same, and an oral care composition using the same are provided. The calcium phosphate-based core-shell structured material includes an amorphous calcium phosphate (ACP) core and a β-tricalcium phosphate (β-TCP) shell covering the core. The method includes a first sintering step and a second sintering step. The first sintering step is to sinter an ACP material at between 700° C. and 800° C. to obtain an α-TCP shell. The second sintering step allows the α-TCP shell to form into the β-TCP shell by sintering at between 800° C. and 900° C. The oral care composition includes a calcium phosphate mixture and an orally receivable carrier. The calcium phosphate mixture includes a powder of the calcium phosphate-based core-shell structured material and a tricalcium phosphate powder mixed in a weight ratio from 3:5 to 3:7.
