Background for Lotioned Wipe Product to Reduce Adhesion of Soils or Exudates to Skin
Cleaning your skin is not an easy problem to solve. Dry tissue products are most commonly used to clean the skin after defecation, urination, and menstruation. Dry tissue products can also be used to remove dirt and food from the skin. Dry tissue products are commonly referred to by the term ‘toilet paper’. ?toilet tissue,? Or ‘paper towels.’ Wet wipes are becoming more popular than dry tissues for cleaning the face, body, genital region, peri-anal, and peri-anal areas after voiding bodily excudates. Wet wipes are also known as ‘wet tissues’. “Wet wipes” are a fibrous material impregnated in a lotion or water-based liquid.
For the purposes of this document, anus, perinea, perineal area, and vulvar are all terms that refer to the area of the pelvis located between, around, and including the external genitalia and anus.
The perineal and vulvar areas are characterized by fine folds (sulci), and hair follicles. These features make it more difficult to clean these anatomical regions. Fecal matter excreted by the anus tends to collect in difficult to reach areas, such as the base of the hairs or the sulci on the skin surface. Menstrual menses can accumulate on skin and hair following the use of a feminine hygiene product. The fecal matter or menstrual matter adheres to the hair and skin more strongly as it dehydrates when exposed to air, or after contact with absorbent materials such as diapers, tissue paper or sanitary towels. The removal of any remaining exudates can be difficult, and this may lead to inadequate cleansing. Infections, irritation, redness and desquamation are all negative effects of inadequate cleansing.
People with pathological conditions, such as hemorrhoids or fissures (cryptitis), are more susceptible to negative effects. The negatives mentioned above are more likely to occur in people with pathological conditions. The benefits of good cleaning after defecation and menstruation are very relevant for babies, toddlers and children. Cleaning must be effective in removing residues, and gentle to avoid irritation. Wet-wipes are a solution to this basic need.
Wet wipes offer several advantages over dry tissues, including:
Manufacturers of wet wipes tried to create wipes that strike the right balance between concepts which are normally antagonistic, such as:
It is still necessary to have a wipe that not only cleans well, but also reduces or stops the adhesion or soiling of exudates and soiling on the skin. This wipe would make cleansing much easier. This wipe can facilitate cleansing, as it reduces the amount of soil or exudates that are deposited on skin after subsequent insults. There may be less soil or exudates left on the surface of the skin when the next cleaning is performed, easier removal of these soils and exudates resulting in less damage to the skin. Also, the soils and exudates are not smeared on the face. It may reduce the amount of time and effort needed by an individual to maintain a satisfactory level of cleanliness.
There is a need for a wipe that can reduce or prevent the adhesion to skin of exudates and soils in a way that’s transparent to the person using it, i.e. Does not require the user to change their habits, such as using a separate wipe.
The Anti-Stick Method can be used to measure the effectiveness of the lotion at removing less than 10% w/w residue soils or excudates. The anti-stick component may be at a concentration equal to or below about 50% w/w in the lotion composition. The anti-stick ingredient may be water-soluble.
The anti-stick agent can be chosen from a group of agents including non-polymeric agents, polymeric agents, silicone copolyols and mono-functional oxide ethers.
The lotion can also contain an emollient or a surfactant.
An article for commerce can be a container containing a product containing lotioned wipes.
The lotioned wipes can be used to prevent soils and exudates from adhering to skin.
The strength of the adhesive interaction between soils or bodily exudates on the skin surface may influence the ease with which they are removed. Reduced adhesion between soils and exudates on the skin can make it easier to remove the exudates. Various materials (hereinafter called anti-stick agents), have been identified as reducing the strength of the adhesion between soils or excudates and the skin. When a substrate is in contact with lotion containing an anti-stick agent, it can reduce the strength of the adhesion to the skin of soils and exudates. This combination of a sub-strate and lotion can be used to create a lotioned wiping product.
As defined herein, ?weight/weight? “As defined herein,?weight/weight? Refers to the weight difference between the referenced component and the referenced total material. The use of w/w in substrates refers to the weight of each component versus the total weight. The use of?w/w? in substrates is a measure of the weight of each component of the substrate compared to the total weight of that substrate. Use of w/w in substrates. The weight of each component of a lotion is compared to the total weight. Use of ‘w/w’ The weight of a material in relation to the weight total of water is called water solubility. Use of w/w The use of?w/w?
A lotion can be used in conjunction with or in contact with a substrate to clean and remove soils or excudates. ?Substrate? Substrate is a general term for a material used to clean body parts. Many of the substrates available today are intended to be used for cleaning the perianal region after a defecation. There may also be other substrates available for cleansing the face or body parts.
The substrate could be nonwoven. ?Nonwoven? Nonwoven refers to a fibrous fabric made by assembling continuous fibers or coextruded fibres or combinations thereof without weaving or knitting. This can be done using processes like spunbonding or carding or meltblowing or airlaying or wetlaying or coform or any other process known in the industry. The nonwoven structure can be made up of one or more layers, each layer containing continuous fibers (or coextruded fibres), noncontinuous fibers (or combinations thereof) and noncontinuous fibers.
The fibers in the substrate can be natural, synthetic, or cellulosic. Cellulosic fibers such as those from hardwood, softwood, and other plants can be examples of natural fibers. Natural fibers can be made up of cellulose, starch or combinations. Cellulosic fibers can be made from a variety of sources, including but not limited to wood pulps, such as eucalyptus and aspen, birch and maple, or reeds. Albardine, esparto (also known by the name viscose), wheat, rice and corn, sugarcane, papyrus (also called jute), reeds, sabias, raphias, bamboos, sidals, kenafs, abacas, sunns, rayons, lyocells, cottons, hemps, flaxs, ramies, and combinations thereof are all examples Other natural fibers can be derived from non-plant sources such as down, feathers and silk. Natural fibers can be modified or treated mechanically or chemically in order to achieve desired characteristics, or they may be in the same form as found in nature. The manipulation of natural fibres by mechanical and/or chemicals does not prevent them from being considered as natural fibers for the purposes of this invention.
The synthetic fibers can be any material, such as, but not limited to, those selected from the group consisting of polyesters (e.g., polyethylene terephthalate), polyolefins, polypropylenes, polyethylenes, polyethers, polyamides, polyesteramides, polyvinylalcohols, polyhydroxyalkanoates, polysaccharides, and combinations thereof. The synthetic fibers may also be single-component fibers (i.e. a single synthetic material, or a mixture of synthetic materials, can make up the entire fiber), bicomponent fibers (i.e. the fiber has been divided into different regions, and the regions include two or more synthetic materials, or mixtures thereof, and may include core and sheath fibres), or combinations thereof. Bicomponent fibers are also an option. These fibers may be used to bind the fibers in the fibrous structure or as component fibers. “Any or all synthetic fibers can be treated either before, during or after manufacturing to alter desired fiber properties.
In certain embodiments it may be desirable that particular fiber combinations provide desired characteristics. It may be desirable, for example, to combine fibers with certain characteristics, such as length, width, coarseness, or another characteristic, in layers. Fibers can be virtually any size, with an average length ranging from 1 mm up to 60 mm. The average fiber length is the length of each individual fiber when it has been straightened. The fibers can have an average width greater than 5 micrometers. Fibers can have an average width ranging from 5 micrometers up to 50 micrometers. The fibers can have a roughness greater than 5 mg/100m. They may also have a roughness ranging from 5 mg/100m to 75 mg/100m.Click here to view the patent on Google Patents.
