Description

DETAILED DESCRIPTION OF THE INVENTION             Clean article treated with high internal phase change emulsion                            Cross-reference of related applications   This application is a pending co-pending application filed on April 30, 1996 by LN Macky et al. It is a continuation-in-part of US patent application Ser. No. 08 / 640,268.                              TECHNICAL FIELD OF THE INVENTION   The present invention provides a wipe that is dry until used, but becomes wet during use. (wipe) related to useful articles. The present application specifically refers to continuous lipid external references. High internal phase inverse emulsion with polar and polar internal phases wet-like clean wipes, including carriers treated with ng wipe). The wipes of the present invention can be used for cleaning hard surfaces and for cleaning baby wipes. Variety, including for cleansing the body, especially for removing solids around the anus It is useful in various applications.                                Background of the Invention   Cleaning the skin is a physical hygiene problem that is not always easily solved. You. Of course, the usual procedure of washing with soap and water works well, but get them Sometimes it is impossible or inconvenient to use. For example, after defecation You can use soap and water to clean around the anus, but such a procedure It is also very troublesome. Therefore, in developing countries, dry tissue The product is the most commonly used post-fecal anal irrigation product. These, dried tea Tissue products are usually referred to as "toilet tissue" or "toilet paper". being called.   The skin around the anus may be affected by the presence of folds and wrinkles (grooves) It is characterized by hair follicles, which make it the most difficult anatomical area to wash. During defecation, fecal discharges tend to be expelled through the anus and tend to accumulate tightly, around the base of the hair. It reaches places, such as in the edges and in grooves on the skin surface. Stool effluent when exposed to air Or dehydrates on contact with an absorbent cleaning means such as tissue paper. Stronger adherence to skin and hair, thus removing residual dehydrated solids later Make it more difficult.   Failure to remove fecal discharge from the anal area has a detrimental effect on body health. Can have. Fecal discharges remaining on the skin after post-defecation washing include bacteria and It is high in virus content, foul-smelling, and generally dehydrated. These features The possibility of perianal disease and body discomfort (eg, itching, inflammation, frictional irritation, etc.) Enhance. In addition, residual stool emissions pollute the underwear and produce an unpleasant odor from the anal area Let it. Therefore, improper peri-anal cleaning can lead to unattractiveness. It is clear.   Suitable for people with anal diseases such as anal itching, hemorrhoids, anal fissures, cryptitis, etc. The importance of perianal irrigation is significant. Perianal diseases usually involve the skin An opening through which bacteria and viruses in residual stool effluent can easily pass. It is characterized by what can be entered. Therefore, people suffering from anal disease After defecation, a high degree of perianal irrigation must be achieved; otherwise, Risk of human disease being exacerbated by bacteria and viruses remaining on the skin Must be affected.   At the same time, those suffering from anal disease can be given a satisfactory level by poor post-fecal cleaning. Face more serious consequences of difficulty removing solids down to . Anal disease can make the surrounding area extremely sensitive and wipe it with normal wiping pressure. This can cause pain when trying to remove stool discharge, and further irritate the skin. obtain. Intense pain when trying to increase solids removal by increasing wiping pressure Bring. Conversely, try to minimize discomfort by lowering the wiping pressure This increases the amount of residual fecal discharge left on the skin.   Conventional toilet tissue products used for anal cleansing are essentially dry, Low-density tissue paper for removing fecal discharge from perianal skin Relies exclusively on mechanical processes. These conventional products are typically Wipes the perianal skin with a pressure of about 1 psi (7 kilopascals), basically Rub or scrape stool discharge from skin. After the first few wipes, a solid layer of The upper part is removed. The wiping process depends on the solids-solids present in the stool effluent. This is because they can overcome the concentration. As a result, cracking occurs in the solid material layer itself. The upper part of the stool layer is removed and the lower part of the solid adheres to the perianal skin Remains.   Traditional tissue products are absorbent, increasing stool emissions with each successive wipe It is dehydrated, making it more adherent to the perianal skin and hair, making its removal extremely difficult. Make it difficult. When the toilet tissue is pressed strongly against the skin around the anus, Fecal discharge is removed more, but it is intense for people with anal disease Painful, rubbing even normal perianal skin, irritation, inflammation, pain, bleeding and Potentially cause infection.   It is retained in the dispenser to improve perianal cleansing and Formally, wipes immersed in a container of a wetting solution have been developed. Made like that Examples of articles include wipes that are often used to clean babies after bowel movements. And those that may have other additives to lubricate the skin in the wetting solution. I will. These wipes have a permanent wet strength and cannot be flushed with water. Ma In addition, these conventional wipes are too wet and can dry out the skin. Flaws tend to have a "cold" feel. The moisture content for each wipe is It may not penetrate.   Dry tissue products that can be moistened have also been used for perianal cleansing. these Wetable tissue products usually have a temporary wet strength, so they are flushed with water be able to. However, users of these products must separately wipe the tissue. Must be done, which can be inconvenient. For such products, the desired moisture It is also difficult to get a level. Also, the temporary wet strength of such products is It is inappropriate in terms of type and needs improvement.   That is, it is a product for cleansing, specifically for body cleansing, and (1) wet Suitable temporary wet strength to have a consistent level of solution and (2) to be able to flow (3) having an appropriate and consistent moisture level to provide effective cleaning; And (4) provide something that remains essentially dry until used for cleaning purposes It is desirable to do.                                Summary of the Invention   The present invention relates to articles useful for cleaning, and in particular, for cleaning hard surfaces.

When used in the form of a clean wipe or used as a baby wipe, It has many significant advantages over purified products. These articles have an internal polar phase during use. Releases a significant amount (eg, and preferably water / water solution), is comfortable and more effective Provides cleanliness. The continuous lipid phase of the emulsion is sufficiently brittle and has low shear deformation ( For example, while wiping the skin), this internal polar phase can be easily released, Hard enough to prevent premature release of the polar phase during harsh processing. This The continuous lipid phase of these articles is also sufficiently stable during storage, and a significant Prevent evaporation. Normal tension and flushability properties of these articles Are not adversely affected when treated with the high internal phase inversion emulsions of the present invention. No. As a result, users of these articles change their normal cleaning habits No need for comfortable and effective wet cleaning.   Applicants have found that when formulating high internal phase emulsions, relatively high viscosity, non-silicone The use of emulsifiers containing I found it. These emulsifiers are low-viscosity emulsifiers, and furthermore, L. Ma on April 27, 1995 Co-pending U.S. Patent Application No. 08 / 430,061 filed by ckey (Case 5563) ), Especially exposed to high shear deformation conditions than the silicon-containing emulsifiers described in Later, it provides better internal phase retention. This can be achieved using high shear dispersion. This is advantageous in that the lugion can be preferably applied to the carrier.   The article of the present invention can be used in addition to a perianal cleansing, a polar fluid such as water, and even a polar fluid. In many other applications that require delivery of additives that can be dissolved or dispersed in the fluid Available. For such applications, wipes for body washing such as baby wipes , Hard surface cleaner for floors, countertops, sinks, bathtubs, toilets, etc. And furthermore the delivery of polar soluble or dispersible antimicrobial or pharmaceutically active agents.
