Formulation

Although they appeared relatively easy to make, even as late as the 1960s, cosmetic chemists still found it tricky to create a formula for loose face powder that functioned well under all conditions.

Certain face powders are readily made, but it is not easy to produce a really good face powder, i. e. one that spreads well and smoothly on the skin, has the right matt look and degree of opacity, wears well in hot weather and blustery weather, is available in a variety of color shades, is attractively perfumed; and is at all times uniform and consistent in quality.

(Wells & Lubowe, 1964, p. 215)

The formula selected was also affected by to how the powder was to be marketed.

Will the powder be used as a finishing touch at the end of a beauty treatment? Will it be the central part of a simpler line around which other products will be built? Will it be subject to high fashion, with types and shades changing from year to year? Will it be a standardized product to reach a more conservative clientele? Is it designed for teenagers or for more mature women? Must it merely remove shine from the face, or should it be highly colored and cover blemishes as well?
