Hygiene product pod and methods of using same

Abstract

A hygiene product, a hygiene product pod, and a method of using the hygiene product pod, the hygiene product pod including a water soluble envelope and the hygiene product sealed in the envelope. The hygiene product includes a carrier comprising butylene glycol in an amount ranging from about 40 wt % to about 70 wt %, based on the total weigh of hygiene product, and an active agent including at least one surfactant.

What is claimed is: 
     
         1 - 9 . canceled 
     
     
         10 . A single-use hygiene product pod comprising:
 a water-soluble envelope; and   a hygiene product sealed in the envelope, the hygiene product comprising:   a carrier comprising butylene glycol in an amount ranging from about 25 wt % to about 70 wt %, based on the total weight of the hygiene product; and   an active agent comprising at least one surfactant.   
     
     
         11 . The pod of  claim 10 , wherein:
 the butylene glycol comprises 1,3-butanediol; and   the hygiene product comprises from about 40 wt % to about 65 wt % 1,3-butanediol, based on the total weight of the hygiene product.   
     
     
         12 . The pod of  claim 10 , wherein the envelope has a pH ranging from about 4.0 to about 9.0, at a temperature of about 25° C. 
     
     
         13 . The pod of  claim 10 , wherein the envelope comprises a polyvinyl alcohol (PVOH) film or a woven or non-woven polyvinyl alcohol (PVOH) fiber. 
     
     
         14 . The pod of  claim 10 , wherein the envelope has a thickness ranging from about 0.5 mm to about 5.0 mm. 
     
     
         15 . The pod of  claim 10 , wherein the hygiene product has a free water content of about 20 wt % or less, based on the total weight of the hygiene product. 
     
     
         16 . The pod of  claim 10 , wherein the hygiene product further comprises a thickener configured to reduce diffusion of the carrier through the envelope. 
     
     
         17 . The pod of  claim 16 , wherein the thickener comprises a lamellar gel network comprising a nonionic surfactant in an amount ranging from about 12 wt % to about 18 wt %, based on the total weight of the hygiene product. 
     
     
         18 . The pod of  claim 16 , wherein the thickener comprises carboxymethyl cellulose in an amount ranging from about 0.15 wt % to about 0.25 wt %, based on the total weight of the hygiene product. 
     
     
         19 . A single-use hygiene product pod comprising:
 a water-soluble envelope; and   a hygiene product sealed in the envelope, the hygiene product comprising:
 a carrier comprising butylene glycol in an amount ranging from about 40 wt % to about 70 wt %, based on the total weight of hygiene product; and 
   an active agent comprising at least one surfactant.   
     
     
         20 . The hygiene product pod of  claim 19 , wherein:
 the butylene glycol comprises 1,3-butanediol;   the hygiene product further comprises carboxymethyl cellulose in an amount ranging from about 0.15 wt % to about 0.25 wt %, based on the total weight of the hygiene product;   the envelope comprises a polyvinyl alcohol (PVOH) film or a woven or non-woven polyvinyl alcohol (PVOH) fiber; and   the active agent comprises at least two compounds selected from:
 sodium cocoyl isethionate; 
 cocamidopropyl betaine; 
 capryloyl/caproyl methyl glucamide and lauroyl/myristoyl methyl glucamide; 
 cocamidopropyl PG-dimonium chloride phosphate; 
 linoleamidopropyl PG-dimonium chloride phosphate; or lauramine oxide.
