Absorbent article comprising a lotion composition for reducing adherence of feces or menses to the skin

Abstract

The present invention relates to lotion compositions comprised on a body facing surface of an absorbent article such as a diaper, training pants or adult incontinence product. The lotion composition may be used for reducing the adherence of feces or menses to the human skin. The lotion composition comprises at least two compounds wherein one first compound is liquid at 25° C. and at least one second component which is solid at 25° C. An effective amount of the lotion composition is comprised on a body facing surface of an absorbent article which is intended to be worn by a wearer.

1 . An absorbent article, intended to be worn by a wearer, wherein at least a part of a body facing surface of that article comprises a lotion composition, the lotion composition comprising at least one first compound which is liquid at 25° C. and at least one second compound which is solid at 25° C.; wherein:
 a) the first compound is one of a liquid polyethylene glycol derivative, a liquid polypropylene glycol, or a liquid polypropylene glycol derivative, and the second compound is one of a solid polyethylene glycol derivative, a solid polypropylene glycol, or a solid polypropylene glycol derivative; or   b) the first compound is one of a liquid polyethylene glycol, a liquid polyethylene glycol derivative, a liquid polypropylene glycol, or a liquid polypropylene glycol derivative, and the second compound is a solid nonionic surfactant with an HLB value of at least 10;   wherein when the solid nonionic surfactant is an ethoxylated fatty alcohol, then the HLB value is at least 13; or   c) the first compound is a liquid fatty acid ester comprising at least one fatty acid unit and at least one ethylene glycol unit and wherein the second compound is a solid polyethylene glycol; or   d) the first compound is a liquid polyethylene glycol, a liquid polyethylene glycol derivative, a liquid polypropylene glycol, or a liquid polypropylene glycol derivative thereof and the second compound is a solid fatty compounds selected from the group consisting of solid fatty acids and solid fatty soaps; wherein when the solid fatty compound is a solid fatty acid, then the total amount of liquids is higher than the total amount of solids.   
   
   
       2 . An absorbent article, intended to be worn by a wearer, wherein at least a part of a body facing surface of that article comprises a lotion composition, the lotion composition consisting of a first compound which is liquid at 25° C. and a second compound which is solid at 25° C.; wherein:
 a) the first compound is one of a liquid polyethylene glycol, a liquid polyethylene glycol derivative, a liquid polypropylene glycol, or a liquid polypropylene glycol derivative, and the second compound is a solid nonionic surfactant with an HLB value of at least 10, wherein when the solid nonionic surfactant is an ethoxylated fatty alcohol, then the HLB value is at least 13; or   b) the first compound is a liquid fatty acid ester comprising at least one fatty acid unit and at least one ethylene glycol unit and wherein the second compound is a solid polyethylene glycol, a liquid polyethylene glycol derivative, a solid polypropylene glycol, or a liquid polypropylene glycol derivative; or   c) wherein the first compound is a liquid polyethylene glycol, a liquid polyethylene glycol derivative, a liquid polypropylene glycol, or a liquid polypropylene glycol derivative, and the second compound is a solid fatty compounds selected from the group consisting of solid fatty acids and solid fatty soaps and solid fatty alcohols;   
   
   
       3 . The absorbent article of  claim 1 , wherein the article comprises on the body facing surface an effective amount of the lotion composition for reducing the adherence of feces or menses to the human skin. 
   
   
       4 . The absorbent article of  claim 1 , wherein the lotion composition is hydrophilic and comprises less than 5 wt % of water by weight of the lotion composition. 
   
   
       5 . The absorbent article of  claim 1 , wherein the amount of the first compound is from 3 to 90 wt. % based on the total lotion composition and the amount of the second compound is from 10 to 97 wt. % based on the total lotion composition and the weight ratio of first to second compound is from 1:32 to 9:1. 
   
   
       6 . The absorbent article of  claim 1 , wherein:
 a) the liquid polyethylene glycol has a molecular weight from 100 Daltons to less than 720 Daltons; or   b) the solid polyethylene glycol has a molecular weight from 720 Daltons to 100000 Daltons; or   c) the solid nonionic surfactant with HLB value of at least 10 is selected from the group consisting of polyethylene glycol C10 to C30-fatty alcohol ethers and polyethylene glycol C10 to C30-fatty acid esters; or   d) the liquid fatty acid ester comprises at least one fatty acid unit and at least one ethylene glycol unit selected from the group consisting of ethoxylated glycerin C6 to C30-fatty acid diesters and ethylene glycol C6 to C30 fatty acid diesters with one or two ethylene glycol units.   
   
   
       7 . The absorbent article of  claim 1 , wherein the lotion composition further comprises at least one dispersed particulate material. 
   
   
       8 . The absorbent article of  claim 1 , wherein the composition further comprises at least one further ingredient selected from the group consisting of anti-foaming agents; antimicrobial agents; antifungal agents; antiseptic agents; antioxidants; cosmetic astringents; drug astringents; biological additives; botanical additives; colorants; deodorants; emollients; external analgesics; film formers; fragrances; humectants; moisturizing agents; opacifiers; skin protectants; cleansing agents; emulsifiers; solubilizing agents; suspending agents; binders; absorbents; buffering agents; and fats and oils. 
   
   
       9 . The absorbent article of  claim 8 , wherein the at least one ingredient is a botanical additive, an antimicrobial agent, an antiseptic agent or an antifungal agent. 
   
   
       10 . The absorbent article of  claim 1 , wherein the absorbent articles are comprised in a package and wherein each package additionally comprises one or more wipes, wherein the ratio of absorbent articles to wipes is from 1:1 to 1:3. 
   
   
       11 . The absorbent article of  claim 1 , wherein the absorbent article comprises one or more of a topsheet, a pair of barrier cuffs, and a pair of leg cuffs, wherein the composition is applied to at least a part of one or more of the topsheet, the pair of leg cuffs, and the pair of barrier cuffs, wherein the topsheet is apertured. 
   
   
       12 . A process of making an absorbent article, comprising the steps of
 (a) providing a lotion composition as defined in  claim 1 ; and   (b) applying the lotion composition to at least one part of the body facing surface of an absorbent article, wherein the lotion composition is applied in an effective amount, and wherein the absorbent article is an article intended to be worn by a wearer.
