Abstract

The present invention provides a composition for a soft urethane foam to prepare a soft urethane foam, comprising a polyol, and a foamed soft urethane foam using the same, wherein the polyol is any one selected from among a hydrocarbon polyol, a vegetable oil, and a vegetable-oil-derived dimer acid, or a mixture of a hydrocarbon polyol with any one selected from among a vegetable oil and a vegetable-oil-derived dimer acid. The present invention provides an impregnation material for impregnation of a cosmetic composition, which can control the polarity of the impregnation material for impregnating a hydrophilic cosmetic composition, and an impregnation-use urethane foam composition for preparing the same.

First claim

What is claimed is:

1. A cosmetic product comprising:
a soft polyurethane foam; and
a cosmetic composition impregnated in the soft polyurethane foam,
wherein the soft polyurethane foam is prepared using a polyol, and
wherein the polyol comprises a polybutadiene polyol selected from the group consisting of cis-1,4-polybutadiene polyol, trans-1,4-polybutadiene polyol, 1,2-polybutadiene polyol and a mixture thereof.

2. The cosmetic product according to claim 1 , wherein the polyol has 2-10 hydroxy functional groups and a number-average molecular weight of 100-100,000 g/mol.

3. The cosmetic product according to claim 2 , wherein the polyol has 2-3 hydroxy functional groups and a number-average molecular weight of 300-50,000 g/mol.

4. The cosmetic product according to claim 1 , wherein the polyol further comprises castor oil.

5. The cosmetic product according to claim 4 , wherein the castor oil is less than 50 wt % based on a total weight of the polyol.

6. The cosmetic product according to claim 1 , wherein the polyurethane foam is prepared by reacting the polyol with an isocyanate compound, wherein the isocyanate compound is a one or more selected from a group consisting of tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), naphthalene diisocyanate (NDI), xylylene diisocyanate (XDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HMDI) and a derivative thereof.

7. The cosmetic product according to claim 1 , wherein the cosmetic composition comprises liquid cosmetic composition.

8. The cosmetic product according to claim 1 , wherein the cosmetic cosmetic composition has a viscosity of 1,000-10,000 cPs at 25° C.
