Hygiene product pod and methods of using same
Disclosed herein are hygiene product pods and a method of using the hygiene product pods. A hygiene product pod can include a water-soluble envelope and a hygiene product sealed in the water-soluble envelope. A hygiene product as described herein can comprise a non-aqueous carrier. A non-aqueous carrier as described herein can comprise a polyol solvent and a polyglyceryl fatty acid ester (PGEs) chassis.
1 . A hygiene product pod, comprising:
a water-soluble envelope; and
a hygiene product sealed in the water-soluble envelope, the hygiene product comprising, based on the total weight of the hygiene product:
a non-aqueous carrier comprising:
one or more polyol solvents in an amount ranging from about 10 wt % to about 30 wt %; and
one or more polyglyceryl fatty acid ester (PGE) chassis in an amount ranging from about 10 wt % to about 50 wt %,
wherein the hygiene product has a free water content of about 18 wt % or less.
2 . The hygiene product pod of claim 1 , wherein the hygiene product is an emulsified liquid or gel.
3 . The hygiene product pod of claim 1 , wherein the hygiene product is a liquid.
4 . The hygiene product pod of claim 1 , wherein the hygiene product comprises, based on the total weight of the hygiene product, one or more surfactants in an amount ranging from about 10 wt % to about 40 wt %.
5 . The hygiene product pod of claim 4 , wherein the one or more surfactants are selected from non-ionic surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, or a combination thereof.
6 . The hygiene product pod of claim 1 , wherein the hygiene product comprises, based on the total weight of the hygiene product, the one or more polyol solvents in an amount ranging from about 15 wt % to about 25 wt %.
7 . The hygiene product pod of claim 1 , wherein the hygiene product further comprises a fragrance oil.
8 . The hygiene product pod of claim 1 , wherein the hygiene product further comprises a pyrrolidone compound in an amount ranging from about 0.5 wt % to about 10 wt %.
9 . The hygiene product pod of claim 8 , wherein the pyrrolidone compound is lauryl pyrrolidone.
10 . The hygiene product pod of claim 8 , wherein the pyrrolidone compound is caprylyl pyrrolidone.
11 . The hygiene product pod of claim 1 , wherein the one or more PGE chassis have a hydrophilic-lipophilic balance (HLB) value of at least 9.
12 . The hygiene product pod of claim 1 , wherein the one or more PGE chassis comprise, based on the total weight of the hygiene product:
polyglyceryl-6 esters in an amount ranging from about 0.5 wt % to about 11 wt %; and
polyglyceryl-2 caprate in an amount ranging from about 5 wt % to about 35 wt %.
13 . The hygiene product pod of claim 1 , wherein the one or more PGE chassis comprise, based on the total weight of the hygiene product:
polyglyceryl-2 caprate in an amount ranging from about 10 wt % to about 50 wt %.
14 . The hygiene product pod of claim 1 , wherein the non-aqueous carrier comprises, based on the total weight of the hygiene product, the phospholipids in an amount ranging from about 1 wt % to about 15 wt %, wherein the phospholipids comprise cocamidopropyl PG-dimonium chloride phosphate and linoleamidopropyl PG-dimonium chloride phosphate.
15 . The hygiene product pod of claim 1 , wherein the water-soluble envelope comprises polyvinyl alcohol (PVOH) or hydroxypropyl methylcellulose (HPMC).
16 . The hygiene product pod of claim 1 , wherein the water-soluble envelope has a thickness ranging from about 0.5 mil to about 10 mil, where a mil is equal to a thousandth of an inch.
17 . The hygiene product pod of claim 1 , wherein the free water content is from about 1% to about 12.5%.
18 . The hygiene product pod of claim 1 , wherein the hygiene product has a water activity of 0.70 aw or less.
19 . The hygiene product pod of claim 1 , wherein the hygiene product is a shampoo, a conditioner, a body wash, a shaving cream, a lotion, or a combination thereof.
20 . The hygiene product pod of claim 1 , wherein the one or more polyol solvents comprises propylene glycol in an amount of from about 10 wt % to about 20 wt %, based on the total weight of the hygiene product.
