title: [Investigation of ambiphilic creams. II. Structural stability].
abstract: Ambiphile creams containing white petrolatum, cetylstearyl-alcohol, Emulgator BTO and distilled water were investigated. The elements of the study of structure-stability were as follows: evaporation of water-phase, mechanical stability of structure and its heatstability. A multiplicative function was found between the loss of mass of creams and the evaporation time. The viscosity vs. temperature function is a two-steps process, it can be divided to a section before melting and an other section after it. Decreasing viscosity under shearing time can be characterized by a logarithmic equation.
