Definitions
- the invention relates to improvement hygiene products made of nonwoven web material having deodorizing properties.
- Hygiene products are used to clean surfaces on the human body, animal body and other surfaces. While traditional products are useful for removing soil and liquid from surfaces, residual soil on the surfaces can cause unpleasant odors. Even a minute amount of malodorous material can cause noticeable odor due to its volatile nature.
- Deodorizing effects can be achieved through odor neutralization, odor masking and antimicrobial treatment.
- Known deodorizing products are generally used separately from cleaning steps.
- Personal care products may include additives which confer desired properties.
- sodium bicarbonate, citric acid and sodium aluminum silicate are additives which have been used to deodorize personal care products after bodily fluids are deposited thereon.
- some feminine hygiene products such as liners and maxi-pads have been manufactured to include deodorizing agents in their absorbent core.
- U.S. Patent No. 5,037,412 issued October 27, 1989.
- a deodorant powder was introduced into a sanitary napkin by encapsulating the powder in a crosslinked polymeric film.
- U.S. Patent No. 5,230,958 issued July 27, 1993.
- Incontinence pads have also been manufactured to include sodium bicarbonate within the pad for its deodorizing properties. The sodium bicarbonate is placed in a position to remain dry, rather than to absorb human exudate, thereby deoderizing the pad.
- U.S. Serial No. 5,342,333 issued August 30, 1994. All of these products provide deodorization of the product after body fluids are deposited and have penetrated through layers of the product. Products which deodorize cleaned surfaces, such as the surface of perinatal region, have not, heretofore, been available.
- Hygiene products such as toilet tissue, wet wipes, and scrubs are also manufactured to include special additives which are meant to confer physical properties to the web material beyond the typical properties of the web material alone.
- lotion has been added to toilet tissue to provide tissue which is more gentle and soft to the skin during use. Durability of the tissue is enhanced by the addition of additives such as wet strength resins which impart additional durability to the web when wet.
- Surfactants are used to enhance the absorbing characteristics of the paper.
- hygiene products having deodorizing properties.
- the hygiene products of the present invention comprise nonwoven web material and at least one odor neutralizing agent.
- sodium bicarbonate is added to at least one outer face of the web material .
- the present invention provides improved hygiene products having cleaning and deodorizing functions.
- the hygiene products of the present invention comprise a nonwoven web material including, but not limited to tissue, paper towel, sponge, carded web, air lay web etc.
- the basis weight of the web material is limited only by limitation imposed by the intended use of the product . For most personal care purposes, the basis weight of web is in the range of from about 5#/R to about 200#/R. In preferred embodiments of the present invention the basis weight is from about 9#/R to about 100#/R.
- odor neutralizing agents applied to these acids act to eliminate malodors .
- Useful odor neutralizing agents of the present invention are safe and non-irritating to the human skin.
- the selected odor neutralizing agent or agents are also low in cost.
- Acetic acid, citric acid, sodium bicarbonate and antimicrobial agents such as Triclosan are examples of odor neutralizing agents which may be used alone or in combination in some embodiments of the present invention.
- the odor neutralizing agent is sodium bicarbonate. Surprisingly, only a small amount of odor neutralizing agent is needed to confer deodorizing properties to the web material .
- the amount of odor neutralizing agent present on the web is 0.1% to 10% (w/w) . In still preferred embodiments of the present invention the amount of odor neutralizing agent present on the web is 0.5% to 5% (w/w) .
- the ideal amount of odor neutralizing agent depends upon the application and the odor neutralizing agent or agents chosen.
- acetic acid or citric acid may be included in the range of about 0.1% to about 5% (w/w) .
- a useful amount of sodium bicarbonate may, for some applications, be from about 0.5% to about 15% (w/w) .
- the web is in the form of a sheet, the sheet, having two opposite faces or surfaces.
- the odor neutralizing agent may be added on one or both faces of the web and may also be distributed within the interstices of the web.
- the odor neutralizing agent may also be placed between the layers.
- placing the odor neutralizing agent exclusively within the core of a multi ⁇ layer product or within the interstices of the web has been found to provide less effective odor control than when the odor neutralizing agent has been added to the face of the web, especially where the product is dry rather than moist.
- the odor neutralizing agent is distributed on at least one face of the web. It is believed that this placement provides optimal contact of the odor neutralizing agent with odor causing agents.
- Hygiene products of the present invention such as toilet tissue or wet wipes may be prepared by a number of methods known to those skilled in the art.
- the method chosen should minimize the amount of odor neutralizing agent in the interior of the web and optimize the amount of odor neutralizing agent on the face of the web. It surprisingly found that despite the presence of odor neutralizing agent on the face of the web, the presence of effective quantities of odor neutralization agent did not result in a product which was unsuitably dusty. For moist products the odor neutralizing agent is preferably distributed throughout the structure of the web.
- the odor neutralizing agent may be added to the web during formation.
- the odor neutralizing agent may be added to the pulping system of a paper machine or a solution containing the agent may be sprayed onto the web while the web is being formed and dried on the paper machine.
- a solution containing odor neutralizing agent may be applied to the web after it has been formed.
- a suspension which contains a high concentration of odor neutralizing agent can be applied directly to a wet web.
- the suspension may also cover the web after it has been transferred to packaging containers. Among other things, this will prevent drying of the wet web.
- Another method which may be used to prepare hygiene products of the present invention is printing the odor neutralizing agent (in a solution) onto the web using, for example, a gravureroll or flexographic techniques known in the art .
- the odor neutralizing agent is coated onto the web using roll coating techniques.
- the odor neutralizing agent may also be applied to coat the web as a dry powder.
- a dry powder may be sprayed, dropped or otherwise applied directly onto the web. Either the web or the powder may be electrically charged. Alternatively, the feeder/spreader may be electrically charged to allow application of dry powder onto the moving web.
- odor neutralizing agent alone, or in combination with other additives or web treatments including, but not limited to lotions, antibacterials, anti-fungals, surfactants, wet- strength resins, softeners or inks.
- additives or web treatments including, but not limited to lotions, antibacterials, anti-fungals, surfactants, wet- strength resins, softeners or inks.
- the reverse roll coating apparatus consists of an anilox roll (a roll with an overall cell pattern to pick up the baking soda suspension) , a rubber roll used to accept the fluid from the anilox roll and to transfer the fluid suspension to the moving web, and a means to deliver the suspension to the anilox roll.
- the baking soda suspension consisted of 40% (w/w) sodium bicarbonate, 3% (w/w) Natrosol (hydroxyethyl cellulose) , and water. The viscosity was
- the dry powder apparatus consists of a fluidized bed container of baking soda and pressurized air, a nozzle to deliver the powder to the moving web, and a shroud to contain and recover the powder.
- a web speed of 1500 fpm baking soda was sprayed onto the surface of the 2-ply 20- lb/2880sq. ft. paper. Quantitative analysis of the baking soda content on the sheet gave a value of 0.54% (w/w) .
- a toilet tissue with surfaces coated with sodium bicarbonate at a 0.5% to 7% (w/w) level is prepared by coating the toilet tissue surfaces with dry sodium bicarbonate powder using a dry powder spray process.
- a baby wipe product containing sodium bicarbonate and lotion is prepared.
- the web material is an airlay material. 0.5% to 9% (w/w) sodium bicarbonate is mixed in a body lotion. The mixture is applied to the web material.
- a wet wipe product containing acetic acid is prepared.
- the web material is carded web. 0.5% to 10% (w/w) acetic acid is applied to the web using a spray method.
- the wet wipe is used to eliminate fish odor at fish preparation stations.
- Example 6 A wet wipe product containing sodium bicarbonate and lotion is prepared for use in adult diaper changes. A 10% to 15% (w/w) suspension of sodium bicarbonate in body lotion is applied directly to a base web.
- the base web is an airlay web.
- a paper towel product containing sodium bicarbonate and a scent is prepared.
- a solution of 10% to 15% (w/w) sodium bicarbonate and a selected scent is printed onto the paper towel web in an ornamental design.
- a solution which simulates urine odor was prepared by combining 50mg phenyl acetic acid, lOO ⁇ L hexanoic acid and 50 ⁇ L butanoic acid in a lOOmL volumetric flask containing about 70mL of distilled water. The contents was mixed until dissolved, then diluted to the lOOmL mark with distilled water and mixed well. This solution contains approximately 2000 pp of mixed carboxylic acids.
- a solution which simulates fecal odor was prepared by combining 75 ⁇ L dimethyltrisulfide, 25 ⁇ L dimethyldisulfide, and 1. OmL of a solution containing 50mg Skatole and 50mg indole in lO L methyl alcohol, in a 100 mL volumetric flask containing about 70mL distilled water. The contents was mixed until dissolved, then diluted to the lOOmL mark with distilled water and mixed well. This solution contains about 1100 ppm of substances said to comprise significant malodorous components of feces volatiles.
- Tissues were treated to have one of 2 levels of baking soda, 0.5% and 2% (w/w) .
- Example 2 Into two separate lOOOmL jars with teflon-lined caps were placed about 1.25 grams of a control tissue or a tissue treated in accordance with Example 2 to have about 0.5% (w/w) baking soda.
- Urine odor simulating solution prepared as described in Example 8, was pipetted onto collagen film in holding rings of 2 inches in diameter. The solution was spread upon the collagen by placing a coverslip over it; after thirty seconds, the coverslip was removed. The solution was then wiped off the collagen using either a control tissue or a tissue treated as described in Example 2 and having one of 2 levels of baking soda, 0.5% and 2.0-% (w/w) . The residual odor of the collagen surface was judged by sniffing. Two panels of judges, 12 and 10 members large, evaluated the residual odor on a scale from 0 (no odor) to 7
- Fecal odor simulating solution prepared as described in Example 9 was pipetted onto three collagen films in holding rings. The solution was spread upon the collagen by placing a coverslip over it. Ten seconds later, the coverslip was removed using a pair of needle nose tweezers . The solution was then wiped from the collagen using a control tissue or a tissue treated as described ir. Example 2 and having about 0.5% (w/w) of baking soda. The residual odor of each of the collagen surfaces was judged by sniffing. The residual odor of the treated tissue was less than that of the control tissue.
- Example 14 Example 14
- Example 15 Simulated sweat odor A solution which simulates sweat odor was prepared by combining 50 ⁇ L isovaleric acid, 50 ⁇ L butanoic acid, 50 ⁇ L valeric acid and 50 ⁇ L hexanoic acid in distilled water. The solution was mixed and distilled water added until the total volume was lOOmL. Then, the solution was mixed again.
- Example 2 Into three separate lOOOmL jars with teflon-lined caps were placed about 0.5 grams of a control tissue or a tissue treated in accordance with Example 2 having one of 2 levels of baking soda, 0.5% and 2.0% (w/w) .
- Example 2 Into three separate lOOOmL jars with teflon-lined caps were placed about 0.5 grams of a control tissue or a tissue treated in accordance with Example 2 having one of 2 levels of baking soda, 0.5% and 2.0% (w/w) .
- Sweat odor simulating solution prepared as described in Example 15 was pipetted onto collagen film " in holding rings of 2 inches in diameter. The solution was spread upon the collagen by placing a coverslip over it and after thirty seconds, the coverslip was removed. The solution was then wiped off the collagen using one of a control tissue or a tissue treated as described in Example 2 having one of 2 baking soda levels, 0.5% and 2.0% (w/w) . The residual odor of the collagen surface was judged by sniffing. Two panels of judges, each 10 members large, evaluated the residual odor on a scale from 0 (no odor) to 7 (high odor) . A statistical test of significance was applied to analyze the data. The difference in odor was significant as subtracting the t 9D xS D value from the average yields a number that is greater than zero, The panel evaluations were as follows:
- ventral surfaces of both forearms of 12 test subjects were cleaned with non-fragrant soap and water and blotted dry. If necessary, the surfaces were shaved first. Subsequently, the forearms were washed with an alcohol- acetone mixture and air-dried. A disc of paper of 1 5/8 inches in diameter was placed onto the clean area of each forearm.
- An odor simulating solution containing 1000 ppm of malodorous components of urine and sweat was prepared as described in Examples 8 and 15. 0.5mL of the solution was dispensed under the disc on each forearm and after 1 minute the disc was removed. One forearm of each test subject, selected at random, was wiped with control tissue, the other forearm with tissue treated as described in Example 2 having a baking soda content of 1% (w/w) .
- ventral surfaces of both wrists of 12 test subjects were cleaned with isopropanol saturated swabs and blotted dry. If necessary, the surfaces were shaved first. A site of 1 5/8 inches in diameter was identified on each wrist. Human feces was donated by all test subjects and 0.20 grams were applied evenly to the site on each wrist. After one minute, one wrist of each test subject, selected at random, was wiped with control tissue, the other wrist with tissue treated as described in Example 2 having a baking soda content of 1% (w/w) .
