Effect of emollient type on physicochemical and functional properties of baby oils

Key words: 

baby oils, emollients.

 The study evaluates the effect of emolient type on the physiochemical and functional properties of baby oils. Based on the literature reports and own studies a baseline baby oil formulation was developed. Next, 10 wt% portions of emollients including (based on INCI) Isostearyl Isostearate, Propylene Glycol Dicaprylate/Dicaprate, PPG-3 Benzyl Ether Ethylhexanoate, PPG-3 Benzyl Ether Myristate, Triethylhexanoin and Caprylic/Capric Triglyceride were added. The ingredients listed above were evaluated with respect to their effects on kinematic viscosity, density, as well as skin hydration, TEWL and natural cattle skin gloss after the application of the products under study. A 10 wt% addition of emollients to the baby oils was not shown to have a significant effect on their kinematic viscosity and density relative to the baseline formulation. Moreover, the oils containing Isostearyl Isostearate and PPG-3 Benzyl Ether Ethylhexanoate demonstrated a capacity for water retention in the epidermis, and all the oils formulated for the study were shown to enhance skin hydration. It was also found that the application of selected emollients in baby oils had a favourable effect on the gloss of natural cattle skin, which was between two- and tenfold higher than in the reference sample containing paraffin oil only.
