Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

Abstract: A sheet product dispenser includes a housing for accommodating a source of a sheet product and a dispenser opening for dispensing the sheet product. The dispenser opening is provided in a rotatable dispensing member. Rotation of the rotatable dispensing member is restricted to one rotating axis. The dispenser opening is offset from the rotating axis of the rotatable member. Rotation of the rotatable dispensing member results from a lateral force applied by a pulled sheet product strip onto the dispenser opening such that the dispenser opening moves as far as possible into a pulling direction so as to minimize an angle between the pulling direction and a dispensing direction of the dispenser opening.

Abstract: The invention relates to the use of a cleansing and/or care composition for impregnating a pile of absorbent supports. The care and cleansing composition has a relatively high apparent viscosity while having a rheological behavior of the shear-thinning and thixotropic type and comprises at least one care and/or cleansing compound. Thus, during an impregnation under stress, especially under pressure and with prior stirring, the composition becomes sufficiently fluid to enable it to rapidly and homogeneously diffuse into the supports arranged in a pile.
