After the war, couture became a source of inspiration: luxury and elegance demanded new textures. The 1950s were marked by the appearance of new synthetic surfactant agents [1], which
allowed new dispersions and new sensorialities [2]. The first nanoemulsions were created.
Women wanted richer, more nourishing creams, which required different preparation modes. Formulas thus used more purified substances (stearin triple pressure), self-emulsifying fatty alcohols, glycol stearates [3]
vegetable, animal, synthetic and microcristalline waxes, polyvinyl alcohols, hydrogenated fats (more resistant to oxidation), sterols, etc. Around 1970, the appearance of low viscosity neutral oils made it possible to soften
the skin without leaving it oily. The word “emollient” became a buzzword.
