Dairy based cosmetic product and process for making

Abstract

The invention is a process for producing a dairy-based cosmetic product, which comprises preparing a premix by mixing whey powder with a liquid carrier, heating the resulting mixture, then cooling the heated mixture, adding a preservative and imidazolidinyl urea to the mixture prior to or after heating to complete preparation of the premix, and formulating a cosmetic product from the premix by adding EDTA or an EDTA salt and citric acid to the premix, and completing the formulation, the cosmetic product containing at least about 3% wt. whey solids basis.

I claim:  
     
         1 . A process for producing a premix for a dairy-based cosmetic product, which comprises preparing a premix by mixing whey powder with a liquid carrier, heating the resulting mixture, then cooling the heated mixture, adding a preservative and imidazolidinyl urea to the mixture prior to or after heating to complete preparation of the premix.  
     
     
         2 . The process of    claim 1   , wherein said preservative is one or more of a paraben, or iodopropyl butyl carbonate, PEG-4, PEG-4 dilaurate, and imidazolinyl urea.  
     
     
         3 . A process for producing a dairy-based cosmetic product, which comprises preparing a premix by mixing whey powder with a liquid carrier, heating the resulting mixture, then cooling the heated mixture, adding a preservative and imidazolidinyl urea to the mixture prior to or after heating to complete preparation of the premix, and formulating a cosmetic product from said premix by adding EDTA or an EDTA salt and citric acid to the premix, and completing said formulation, said cosmetic product containing at least about 3% wt. whey solids basis.  
     
     
         4 . The process of    claim 1   , further comprising adding EDTA or a salt thereof, and citric acid to the premix, and formulating a cosmetic product with said premix, whereby the cosmetic product contains at least about 3% wt. whey solids basis.  
     
     
         5 . The process of    claim 3   , wherein said liquid carrier is water or a pasteurized or unpasteurized whey.  
     
     
         6 . The process of    claim 3   , wherein said preservative is one or more of from about 0.1% to about 1% wt. of a paraben, or iodopropinyl butyl carbamate, PEG-4 laurate, PEG-4 dilaurate, and fom about 0.1% to about 0.7% wt. imidazolinyl urea.  
     
     
         7 . The process of    claim 3   , wherein said heating is to a temperature between about 50° C. and under its boiling point, and said preservative is a mixture of phenoxyethanol, and one or more of methylparaben, ethylparaben, propylparaben, and butylparaben.  
     
     
         8 . The process of    claim 3   , wherein said heating is carried out for a period of time between about 20 minutes and about 1 hour.  
     
     
         9 . The process of    claim 3   , wherein said heating is carried out under reduced air pressure.  
     
     
         10 . The process of    claim 3   , wherein the water is distilled or deionized water.  
     
     
         11 . The process of    claim 6   , wherein said step of cooling is carried out in two stages, and the preservative and the imidazolidinyl urea are added to said mixture after the first stage of cooling.  
     
     
         12 . The process of    claim 11   , wherein the preservative is added to the mixture before heating, and imidazolidinyl urea is added to the mixture after the first cooling stage.  
     
     
         13 . The process of    claim 12   , wherein said liquid carrier is substantially pasteurized or fresh liquid whey.  
     
     
         14 . The process of    claim 3   , wherein said step of formulating a cosmetic product from the premix is carried out one or more days after the premix was prepared.  
     
     
         15 . A process for preparing a bath powder, which comprises a mixture of from about 60 to about 85% wt. powered whey, silica, sodium bicarbonate, an a preservative.  
     
     
         16 . The process of    claim 15   , wherein said preservative is PEG-4 laurate, PEG-4 dilaurate, or iodopropinyl butylcarbamates.  
     
     
         17 . The product of the process of    claim 3   .
