Claim 0:
1. A method for making a roll of sanitary tissue product comprising a sanitary tissue product comprising a plurality of dry fibrous structure sheets, the method comprising the steps of:
a) providing a sanitary tissue product comprising a plurality of dry fibrous structure sheets;
b) applying a surface care composition comprising one or more bacteriophage to the dry fibrous structure sheets, such that the surface care composition is present on surfaces of the plurality of dry fibrous structure sheets;
c) convolutedly winding the sanitary tissue product such that the surface care composition is present throughout the roll of sanitary tissue product and wherein the surface care composition comprises at least about 102 PFUs of one or more bacteriophage residing on the surfaces of the plurality of dry fibrous structure sheets such that the sanitary tissue product exhibits all of the following properties:
a. a moisture content of less than 20% by weight of the sanitary tissue product as measured according to the Water Content Test Method;
b. a GM Tensile Strength of greater than 200 g/in as measured according to the Tensile Test Method;
c. a density of less than about 0.60 g/cm3 as measured according to the Density Test Method; and
d. a basis weight of greater than 5 g/m2 to about 120 g/m2 as measured according to the Basis Weight Test Method; and
wherein the sanitary tissue product roll exhibits the following properties:
i. a roll bulk of greater than 4 cm3/g; and
ii. a % compressibility of less than 10% as measured according to the Percent Compressibility Test Method.
