Abstract
Process for preparing toilet soap bars containing high molecular weight polymers of ethylene oxide, said bars characterized by having a smooth surface like that of conventional soap bars.
Claims17
Process for preparing toilet soap bars containing, approximately by weight, at least 60% of soap and between 0.5 and 10% of poly (ethylene oxide) having an average molecular weight of at least about 100,000 which comprises forming a first mixture of said soap in the form of chips and said poly(ethylene oxide) in the form of powder, said first mixture containing at least about 11% of moisture by weight of said chips whereby the surfaces of said soap chips are in powder-adherent condition with respect to said poly (ethylene oxide) powder, to produce soap chips having poly (ethylene oxide) bonded thereto, then mixing other conventional soap bar ingredients with said bonded chips to form a second mixture, then forming said second mixture into a soap bar.
A toilet soap bar containing by weight, about 0.5 to 10% of poly (ethylene oxide) having a molecular weight of at least 100,000 and at least 60% of soap, said bar being substantially free of visible specks caused by said poly(ethylene oxide).
