WO19091855A1: Use of an activated aluminium sesquichlorohydrate (AASCH) as an antimicrobial agent on the surface of human body, characterised in that the AASCH comprises aluminium sesquichlorohydrate, a water-soluble calcium salt and an amino acid.

WO18086797A1:  The present invention is in the field of antiperspirant compositions, in particular compositions comprising antiperspirant actives. The present invention more particularly relates to compositions comprising titanium based antiperspirant actives which are stable before use and effective in ensuring long-lasting antiperspirancy benefit.

US2019159976A:  An antiperspirant aerosol product having good environmental sustainability and comprising an anhydrous antiperspirant aerosol composition comprising an AP active comprising a basic aluminium chloride compound 5 of formula Al2OH4.4Cl1.6 to Al2OH4.9Cl1.1, water soluble calcium salt and amino acid, and an aerosol dispenser comprising a container body, an aerosol valve, and a valve actuator; characterised in that the product has a Combined Sustainability Index (CSI) of less than 3.0, where: CSI=AlF +VOCF +MCB/N10 AlF being the weight (in centigrams) of aluminium expelled per spray; VOCF being the weight of VOC (in grams) expelled per spray; MCB being the weight of metal (in grams) in the container body; and N is the number of spray applications possible from the fully charged product, each figure being based on a spray duration of 2 seconds

US2018311119A:  An antiperspirant aerosol product having good sustainability characteristics and comprising an anhydrous antiperspirant aerosol composition comprising particulate antiperspirant active suspended in a carrier oil, the ratio of propellant to 5 base composition being from 2:1 to 4:1 by weight and an aerosol dispenser comprising a container body, an aerosol valve, and a valve actuator; characterised in that the particulate antiperspirant active comprises a basic aluminium chloride compound of formula Al2OH4.4Cl1.6 to Al2OH4.9Cl1.1, water soluble calcium salt and an amino acid and the aerosol valve of the aerosol 10 dispenser has a vapour phase tap (VTP) to restrictive tailpiece (RTP) ratio of from 0.6:1 to 1.2:1.

WO16078898A1:  An antiperspirant composition is disclosed which comprises hydrophobically modified particles selected from the group consisting of silica, metal oxide and mixtures thereof, amino functionalized silicone, water and an antiperspirant active.

US2016136066A: An aqueous composition comprising an aluminium sesquichlorohydrate salt, water soluble calcium salt, and amino acid, wherein the molar ratio of water soluble calcium salt to aluminium is at least 1:40 and the molar ratio of amino acid to aluminium is at least 1:20 and methods for making such compositions having enhanced antiperspirancy performance

US2017333307A:  A process for manufacture of an antiperspirant composition comprising the reaction of an aqueous solution of aluminium sesquichlorohydrate, water soluble calcium salt and amino acid, at a total anhydrous solids content of from 33 to 60 percent by weight and at a temperature of at least 65 degrees centigrade, for a period of from 1 to 24 hours, wherein the molar ratio of water soluble calcium salt to aluminium sesquichlorohydrate is at least 1:40 and the molar ratio of amino acid to aluminium sesquichlorohydrate is at least 1:20, the mixture then being cooled to less than 25 degrees centigrade and diluted with at least an equal weight of water or to a total anhydrous solids content of less than 31 percent by weight, the dilution phase being performed within 10 days of cooling phase

US2018015012A:  An anhydrous antiperspirant aerosol composition comprising a particulate antiperspirant active system, suspending agent, carrier oil, and liquefied propellant gas, characterised in that the particulate antiperspirant active system comprises an aluminium sesquichlorohydrate of formula AI2OH4.4CI1.6 to AI2OH4.9CI1.1 activated with a water soluble calcium salt. 

US2017312197A:  An anhydrous antiperspirant stick or soft solid composition comprising an antiperspirant active system, thickening agent, and non-aqueous carrier oil, characterised in that the particulate antiperspirant active system comprises an aluminium sesquichlorohydrate of formula AI2OH44CI1.6 to AI2OH4.9CI1.1 activated with a water soluble calcium salt.

US2016106644A:  A UHT process for the manufacture of an aqueous antiperspirant composition comprising the steps of: (i) mixing aluminium-containing antiperspirant salt, water soluble calcium salt, amino acid, and water, (ii) heating the mixture to a temperature of greater than 100 degrees centigrade at a pressure of greater than 1 Bar (100,000 Pa) and (iii) restoring the mixture to ambient temperature and pressure

US2015224039A:   An oil-in-water emulsion cosmetic composition comprising solid particulates of 2-hydroxystearic acid having a particle size distribution such that 99 percent or more by weight have a particle size of less than 125 microns and a method of manufacture of such a composition.
