Hygiene product pod and methods of using same
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.
1. A method comprising: contacting a hygiene product pod comprising a water-soluble envelope and a liquid hygiene product encapsulated within the water-soluble envelope with an amount of water sufficient to dissolve the water-soluble envelope and release the liquid hygiene product, wherein the liquid hygiene product is a shampoo, bodywash, conditioner, or any combination thereof, and wherein the liquid hygiene product comprises:
(a) a glycol carrier, wherein the glycol carrier comprises at least one of: a butylene glycol, a propylene glycol, dipropylene glycol; or N-acetyl diglycoamine;
(b) a plurality of non-ionic surfactants in a combined amount of from about 2 wt % to about 12 wt %, based on the total weight of the liquid hygiene product, wherein the plurality of non-ionic surfactants comprises capryloyl methyl glucamide, caproyl methyl glucamide, lauroyl methyl glucamide, and myristoyl methyl glucamide; and
(c) a cationic surfactant in an amount of from about 1 wt % to about 12 wt %, based on the total weight of the liquid hygiene product, wherein the cationic surfactant comprises linoleamidopropyl PG-dimonium chloride phosphate;
wherein the liquid hygiene product does not dissolve the water-soluble envelope when encapsulated in the water-soluble envelope, and wherein the liquid hygiene product does not phase separate within the water-soluble envelope.
2. The method of claim 1 , wherein the liquid hygiene product further comprises at least one anionic surfactant.
3. The method of claim 1 , wherein the liquid hygiene product further comprises at least one amphoteric surfactant.
4. The method of claim 3 , wherein the at least one amphoteric surfactant is cocamidopropyl betaine.
5. The method of claim 4 , wherein the cocamidopropyl betaine is present in an amount of from about 1 wt % to about 10 wt %, based on the total weight of the liquid hygiene product.
6. The method of claim 4 , wherein the cocamidopropyl betaine is present in an amount of from about 4 wt % to about 6 wt %, based on the total weight of the liquid hygiene product.
7. The method of claim 1 , wherein the water-soluble envelope dissolves in the amount of water at a temperature of about 25° C. in a time period of from about 3 seconds to about 15 seconds.
8. The method of claim 1 , wherein the liquid hygiene product further comprises a quaternary ammonium salt.
9. The method of claim 1 , wherein the liquid hygiene product further comprises an additional non-ionic surfactant.
10. The method of claim 1 , wherein the glycol carrier comprises the butylene glycol, wherein the butylene glycol comprises 1,2-butanediol, 1,3-butanediol, 2,3-butanediol, or 1,4-butanediol.
11. The method of claim 1 , wherein the glycol carrier is in an amount that comprises about 21 wt %, based on the total weight of the liquid hygiene product.
12. The method of claim 1 , wherein the linoleamidopropyl PG-dimonium chloride phosphate is present in an amount of about 5 wt %, based on the total weight of the liquid hygiene product.
13. The method of claim 1 , wherein the liquid hygiene product further comprises lauramine oxide.
14. The method of claim 1 , wherein the liquid hygiene product further comprises cetyl alcohol.
15. The method of claim 1 , wherein the liquid hygiene product further comprises stearyl alcohol.
16. The method of claim 1 , wherein the liquid hygiene product comprises a free water content of about 20 wt % or less, based on the total weight of the liquid hygiene product.
