Towards a new era (1)

<< < > >> |

After the war, life progressively resumed its normal course. Research was at last free to develop. Emile Mahler, from the laboratory Gattefossé in Lyons, presented physicochemistry as a method to characterize creams
(nature of the continuous phase, structure, hardness, resistance to desiccation). He thus introduced rheology [1] as a science in the cosmetic industry at a time when new compact and
stable emulsions based on self-emulsifying waxes were first created.
Around 1948 another pioneer, Pierre Vélon, from Lancôme SA research laboratory, developed the use of a series of characterizations of cosmetic products (iodine value [2] hydroxyl value [3],
viscosity, wetting capacity [4] etc.) and provided care advice based on the three following imperatives: “balancing, protecting, cleansing.”
