초록 ▼

A method and composition for preparing a stable clear liquid release agent comprising at least two oils of an animal or vegetable fat and from about 0.25 to 2.0 percent by weight polysorbate 80 in which the oil present in a major portion is a liquid at room temperature and the oil present in a minor portion is a solid at room temperature. The method comprises forming a uniform mixture by agitating the oils at a temperature on the order of 74°C. followed by rapidly and uniformly chilling the mixture with agitation to at least about 25°C. and working the chilled mixture. Preferably the mixture is pre-cooled and homogenized prior to the rapid chilling step. Further, after the rapid chilling step the resultant blend is packed with CO2 propellant to yield an environmentally safe aerosol product. The resultant blend of oils presents a brighter and clearer appearance and is less susceptible to separation than conventionally blended oil mixtures.
