#alltheingredients: Ethylhexyl palmitate – Guerbet ester, low viscosity dimethicone substitute

You can find the home page for the Guerbet ester series by clicking this link! I’ll update it every time we meet a new ester! I’ll be referring quite a lot to the the combining emollients series in which we learned how properties like viscosity, surface tension, saturation, molecule size, molecule weight, molecule shape, polarity, and...
