Definitions

  • the present invention relates to improvements in cellulosic fibrous webs and more particularly to those webs intended for use as towels, toilet tissue and facial tissue.
  • a web of cellulosic fibres characterised in that it comprises as a water-soluble emmolient an agent selected from:-
  • the invention also includes towels, toilet tissue and facial tissue characterised by being made from such a cellulosic fibrous web.
  • Lauroamphoglycinate is the amphotenic organic compound that conforms generally to the formula:
  • Lauroamphoglycinate is sold in the form of a proprietory product under the name Alcolac DV-1995 which contains principally Lauroamphoglycinate together with phosphoric acid and a nonionic surfactant.
  • High molecular weight cationic quaternary homopolymers or copolymers derived from a dimethyl diallyl ammonium salt are disclosed and described in detail in U.S. Patents 3,288,770 and 3,412,019. Although such polymers have been disclosed for use in cosmetic products such as shampoos (U.S. patent 3,996,146), for bleaching compositions (U.S. patent 4,027,008), for hair colouring compositions (U.S. patent 3,986,825) and for hair waving compositions (U.S. patent 3,912,808), they have not hitherto been recognised as skin moisturisers. High molecular weight polymers of this type are commercially available from Calgon Corporation, a wholly-owned subsidiary of Merck and Co. under the brand name Merquat.
  • Triquaternary phospholipid complexes are described in detail in U.S. Patent 4,209,449. They are derived from fatty acids such as stearic, lauric, linoleic and myroistic acids. Whilst such phosolipid complexes have been recognised as possessing skin moisturising properties, they have never hitherto been employed or incorporated in cellulosic fibrous webs. Furthermore, it could not have been predicted that such water soluble compounds would transfer from tissue made from such webs during the drying of water from the skin or in the wiping of bodily fluids from the skin. Such phospholipid complexes are commercially available from Mona Industries Inc. under the brand name Monoquat and Monaterge. The stearic based complex bears the CTFA designation stearamidopropyl PG-Dimonium Chloride Phosphate.
  • Glucose glutomate is a condensation product of an amino acid with a reducing sugar. Such condensation products are disclosed and described in detail in U.S. patent 3,231,472. They are commercially available from Wickhen Products Inc. a wholly owned subsidiary of Dow Corning, under the brand name Wickenol. It has been found that the presence of small residual amounts of glucose glutomate on the skin, after hand drying, materially aids in restoring and maintaining the moisture balance necessary for healthy skin. It is surprising however that this material will transfer from a tissue containing it in the act of drying water from the skin and particularly when it is present in the tissue in an amount of only from .1 to 2 percent by weight of the tissue.
  • the general method of treating the cellulosic fibrous webs with the active agents is as follows:- Paper webs having a basis weight of 54 g/m2 (32 pounds per ream of 2,800 square feet) were treated in the finishing process at a point after the paper has been unwound from the parent roll and embossed, but before the slitting, folding, cut off stacking and wrapping processes.
  • the treating fluid comprising the active ingredients dissolved in water, is applied at a rate to yield the addition of between 0.034 to 1.086 g/m2 (0.02 to 0.64 pounds per ream) of lauroamphoglycinate or triquaternary phospholipid (0.1 to 2.0% by weight of the web).
  • any application technique known in the art which does not unduly compact the web and which evenly distributes the fluid at the desired rate onto the paper web may be employed.
  • These application techniques include spraying, transfer roll coating and gravure printing. If compaction caused by gravure printing is considered too great to the finished product, this step may be carried out prior to the step of bulking by embossing.
  • the amount of compaction which can be suffered is influenced by numerous variables much as the original bulk of the web, consumer expectstions regarding bulk and the perceived need for patterned printing which can be achieved by gravure roll methods.
  • the present applicants have found that the benefits perceived by users are best achieved by spraying the treating fluid onto the web. In the examples which follow a method is employed which may be described as a doctored kiss roll method.
  • the path of the paper web is directed over an application roll which rotates in the same direction as the travel of the paper.
  • This roll which has a smooth surface, for example polished chrome, rotates partially submerged in a bath of the fluid to be applied. As the roll rotates, it picks up a layer of liquid on its surface. The thickness of this layer is determined by the viscosity of the fluid. This layer is then metered to the desired thickness by doctoring the excess off of the roll. The paper, moving faster than the surface of the roll, then wipes the doctored layer of fluid from the roll.
  • the rate of application for a given paper speed and fluid is controlled by adjustment of the speed of rotation of the coating roll; the angle of wrap (contact with the roll) of the paper over the coating roll; and the type of and setting of the doctor. These adjustments are made as required to deliver the desired quantity of fluid to the web for a given speed and fluid.
  • a sheet was prepared as follows: To paper web having a basis weight of 32.8 pounds per ream of 2880 square feet (55.6 grams per square meter) was applied in the above described manner a quantity of alcolac DV-1995 containing principally lauroamphogylcinate with phosphoric acid and a nonionic surfactant to yield a lotionized sheet containing 0.64% lauroamphoglycinate by weight of web.
  • This example illustrates the ability of people to discern differences and benefits from towels treated in accordance with this invention as compared to untreated towels and to appreciate that the functional properties of the treated towels remain unchanged.
  • These products exhibit the ability to transfer chemicals from the cellulosic fibrous web to the skin generating emollient benefits while concomitantly successfully executing the primary function of the product which is to wipe or dry the skin.
  • the methodology employed involved choosing a panel of normal, healthy individuals and observing whether this panel (which consisted eleven members 1 3 ) would be able to perceive beneficial differences amongst treated towels and untreated Scott Brand 150 C-fold towels, the towels were presented to the panel with a code number so that the sample identifications were unknown to each panelist.
  • the investigation was carried out privately by each panelist so that there was no interaction with other panelists.
  • Each panelist was to wash their hands with luke warm tap water and a mild liquid soap and then their hands were dried with an untreated towel. The subjects knew specifically that these towels were normal untreated towels and that these towels were utilized as a reference standard.

  • Each panelist was to wash their hands with luke warm tap water and a mild liquid soap and then their hands were dried with an untreated towel.
  • the subjects knew specifically that these towels were normal untreated towels and that these towels were utilized as a reference standard.
  • the subjects were then asked to rewash their hands using an identical procedure and this time they were asked to dry their hands with a coded unknown towel.
  • a paper web having a basis weight of 33.5 pounds per ream of 2880 square feet (56.8 grams per square meter) was sprayed on one side of the sheet with Merquat 100 containing 4% by weight of the high molecular weight polymers of the present invention in solution to yield a lotionized sheet containing 0.2% of said polymers by weight of web.
  • a paper web having a basis weight of 32.1 pounds per ream of 2880 square feet (54.5 grams per square meter) was sprayed on one side of the sheet with Merquat 100 containing 2.4% by weight of the high molecular weight polymers of the present invention in solution to yield a lotionized sheet containing 0.17% of said polymers by weight of web.
  • Alcohol lanolin RRT-1-200A
  • Towels fabricated from sheets made in accordance with the proceeding Examples 3a and 3b and the Comparative Example and a control towel were tested by a panel of nurses to evaulate the condition of their hands after repeated drying of their hands. Sensory perceptions are, of course, subjective; however, the results it is believed, validly rank to towels in relation to on another.
  • the testing procedure asked participants to compare the condition of their hands after four dryings with a control towel against four dryings with a test towel.
  • the control towel consisted of untreated paper towels, commercially avialable as SCOTT Brand 150 C-fold towels. All test towels were kinder to participants' hands than the control towel, as evidence by the percentage stating their hands felt the same or better after dryings.
  • the length of time it took to dry hands with the control towel and the test towel was the same. On average, the drying time was sixteen seconds.
  • the testing procedure comprised a wash and dry sequence as follows: one wash and dry with control towel, followed by one with test towel; four wash and dry sequences with control towel followed by four with test towel; and finally five with test towel.
  • two-thirds of the participants said their hands felt better, one-third said they felt the same and none said their hands felt worse.
  • a towel made in accordance with Example 3b 46% of the participants said their hands felt better, 38% said their hands felt the same and 15% said their hands felt worse.
  • In the test of towels made in accordance with the Comparative Example (lanolin) at the end of the test 27% of the participants said their hands felt better, 9% said they felt the same and 64% said their hands felt worse.
  • Alcolac lanolin RRT-1-200A
  • Towels fabricated from sheets made in accordance with the preceding Example 4 and the Comparative Example and a control towel were tested by a panel of nurses to evaluate the condition of their hands after repeated drying of their hands. Sensory perceptions are, of course, subjective; however, the results, it is believed, validily rank the towels in relation to one another.
  • the testing procedure asked participants to compare the condition of their hands after four dryings with a control towel against four dryings with a test towel.
  • the control towel consisted of untreated paper towels, commercially available as SCOTT Brand 150 C-fold towels. All test towels were suited to participants' hands than the control towel, as evidenced by the percentage stating their hands felt the same or better after the dryings. The length of time it took to dry hands with the control towel and the test towels was the same.
  • the testing procedure comprised a wash and dry sequence as follows: one wash and dry with control towel, followed by one with test towel; four wash and dry sequences with control towel followed by four with test towel; and finally five with test towel.
  • towels made in accordance with Example 4 Wickenol
  • 58% of the participants said their hands felt better 17% said they felt the same and 25% said their hands felt worse.
  • towels made in accordance with the Comparative Example (lanolin) at the end of the test 27% of the participants said their hands felt better, 9% said they felt the same and 64% said their hands felt worse.
