Abstract

Abstract There is disclosed herein an improved cream-like nail polish remover consisting of a neutralizing-system and gelling-agent component, a solvent component, and an additive component. The component includes a gelling agent of an acrylic acid monomer and a neutralizing system N,N,N',N'-Tetrakis (2-hydroxypropyl) ethylenediamine and 2-ethyl-N-(2-ethylhexyl-1-hexamine. The solvent can be 2(3H)-furanone, dihydro-, which has a low vapor pressure at room temperature and a flash point above room temperature.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 118 words
A cream-like nail polish remover composition consisting of: a solvent in an amount effective to remove nail polish from a nail; a gelling agent in an amount effective to provide a cream-like consistency; a neutralizing system in an amount effective to cooperate with said gelling agent to render the composition essentially cream-like with a viscosity greater than about 800 centistokes and being a mixture of N,N,N',N'-tetrakis (2-hydroxy propyl) ethlene diamine and z-ethyl-N-(2-ethyl hexyl)-1-hexamine in the amount of between 1.8 and 4.4. weight percent; an antibacterial agent in an amount effective to inhibit bacterial growth; and water in an amount effective to balance the other ingredients and minimize the requirements for said other ingredients and permit the functioning thereof.
Claim 2
Dependent Claim 118 words
A cream-like nail polish remover composition consisting of: a solvent in an amount effective to remove nail polish from a nail; a gelling agent in an amount effective to provide a cream-like consistency; a neutralizing system in an amount effective to cooperate with said gelling agent to render the composition essentially cream-like with a viscosity greater than about 800 centistokes and being a mixture of N,N,N',N'-tetrakis (2-hydroxy propyl) ethlene diamine and z-ethyl-N-(2-ethyl hexyl)-1-hexamine in the amount of between 1.8 and 4.4. weight percent; an antibacterial agent in an amount effective to inhibit bacterial growth; and water in an amount effective to balance the other ingredients and minimize the requirements for said other ingredients and permit the functioning thereof.
