Abstract

The present invention is related to the use of glyoxal-free compositions, more particularly, to the use of hydroxyethylcellulose agglomerated with low molecular weight hydroxyethylcellulose in consumer products, in particular, pharmaceutical, personal care (excluding oral care compositions), as well as household care applications.

Claims (15)

1. A consumer product comprising:

a) a glyoxal-free agglomerated hydroxyethylcellulose composition,

b) a consumer product active ingredient material, and

c) water,

wherein the glyoxal-free agglomerated hydroxethylcellulose composition comprises spraying a particulate hydroxyethylcellulose with an aqueous solution of a low molecular weight hydroxyethylcellulose; wherein the consumer product is selected from the group consisting of pharmaceutical, personal care and household care applications, wherein the consumer product is not an oral care composition; and wherein the low molecular weight hydroxyethylcellulose has a lower molecular weight than the particulate hydroxyethylcellulose and exhibits a viscosity in a 2% aqueous solution of less than 350 cps.

2. The consumer product of claim 1 , wherein the low molecular weight HEC exhibits a viscosity in a 2% aqueous solution of approximately 15 cps.

3. The consumer product of claim 1 , wherein the consumer product comprises a hair conditioner.

4. The consumer product of claim 1 , wherein the glyoxal-free agglomerated hydroxyethylcellulose composition has a particle size range of 400-800 microns.

5. The consumer product of claim 1 , wherein the glyoxal-free particulate hydroxyethylcellulose has a 1% aqueous viscosity of 1500 to 2500 cps at 25° C.

6. The consumer product of claim 1 , wherein the consumer product comprises a skin lotion.

7. The consumer product of claim 1 , wherein the consumer product comprises a shampoo.
