N1 - Claims(WO19007916A1): [EN] CLAIMS 1. An aqueous antiperspirant composition comprising: i) at least 2 wt percent of water soluble, antiperspirant active comprising aluminium ions and chloride ions, and ii) from 0.1 to 4.0 wt percent of defibrillated primary cell wall material wherein at least 50 wt percent of the total material is sourced from plant parenchymal tissue. 2. A composition according to claim 1, wherein the defibrillated primary cell wall material has an average crystallinity of less than 50 percent. 3. A composition according to claim 1 or 2, wherein the defibrillated primary cell wall material comprises at least 50 wt percent of cellulose microfibrils, based upon the total dry weight of the defibrillated primary cell wall material. 4. A composition according to any of the preceding claims, wherein at least 80 percent by weight of the defibrillated primary cell wall material has a diameter of less than 50nm. 5. A composition according to any of the preceding claims, wherein the defibrillated primary cell wall material is sourced from parenchymal tissue selected from citrus fiber, tomato fiber, sugar cane fiber and mixtures thererof. 6. A composition according to any of the preceding claims, wherein the water soluble antiperspirant active is present at from 4 to 25 percent by weight, preferably from 10 to 20 percent by weight. 7. A composition according to any of the preceding claims, wherein the water soluble antiperspirant active is an astringent antiperspirant salt selected from an aluminium or an aluminium-zirconium chlorohydrate salt or complex, preferably aluminium sesquichlorohydrate. 8. A composition according to any of the preceding claims, comprising an oil phase, wherein the composition is in the form of oil-in-water emulsion. 9. A composition according to any of the preceding claims, in the form of a roll-on, lotion, cream or gel. 10. A product comprising a composition according to any of the preceding claims, contained within a dispenser that allows flow of the composition onto the surface of the human body, 1 1. A product according to claim 10 that is a roll-on composition contained within a roll- on dispenser. 12. A manufacturing process for the composition according to any of claims 1 to 9, comprising the defibrillation in an aqueous medium of primary cell wall material sourced from plant parenchymal tissue, wherein during or after the defibrillation a water soluble antiperspirant active is mixed in. 13. A manufacturing process according to claim 12, wherein the defibrillation comprises a high-shear treatment step using a high pressure homogenizer at the pressure of at least 200bar, preferably at least 500bar, most preferably at least 1000bar. 14. A method of reducing perspiration from human skin in which an antiperspirant composition according to claim 1-9 is applied to the axillary skin. 15. A method of thickening an aqueous antiperspirant composition comprising at least 2 weight percent of water soluble antiperspirant active comprising aluminium ions and chloride ions, said method comprising the addition of from 0.1 to 4.0 weight percent of defibrillated primary cell wall material wherein at least 50 wt percent of the total material is sourced from plant parenchymal tissue.
