In the emulsion formulation selected for this study, both water
and humectants and emollients that have skin lubricating features
were used together with occlusive agents that resoften and reelasticise
the skin. And, emulsion type was selected by taking the effects
of the products while being in use into account.
While W/O type emulsions provide more humidity in the skin,
they form a film layer which is more oily and viscous. Therefore,
they are not commonly preferred in cosmetic terms. And, O/W
type emulsions are more commonly used than W/O type emulsions
for they are very well tolerated by the users although they have
lower emollient and occlusive effects compared to the W/O type
emulsions (Choudhury et al., 1985). For these reasons mentioned
above, all emulsions in our study were prepared in O/W type. In
our study, it has been aimed at obtaining a formulation which has
a high moisturizing feature based on the emulsification of collagen
hydrolysate. Organoleptic features and the physical properties of
the product were evaluated in the preparatory studies performed,
and basic formulas one for each in the form of O/W type emulsions
were selected. According to the essential oil proportions, 3
