European Union Guidelines -,,Data on composition between L+ lactic acid and other acids. Moreover,
and undesirable effects should be easily accessible to results of synergy studies are presented and the actual
the public -practical implementation of the Article BPD status of L+ lactic acid is discussed. To complete
7a(l)(h) of the Cosmetics Directive 76/768/WE" the picture, other important functionalities of L+ lactic
acid (e.g. descaling) in detergents are reviewed. L+
lactic acid is produced through fermentation of

Ingredient For Acidic Cleaners

L+ lactic acid and lactates have been used for many
years in a wide variety of food products as a natural
preservative, because L+ lactic acid and lactates have a
proven functionality as a bacteriostatic agent. In this
respect L+ lactic acid gains more and more interest in
hygienic or disinfecting detergents formulations. In
addition, there is a clear trend towards more safe and
sustainable ingredients and detergents formulations.
Traditional biocides, on the other hand, are under
pressure due to toxicity issues, build-up of resistance
(e.g. Triclosan) and harm to waste water. This article
zooms in on the mechanism behind the anti-microbial
functionality of lactates and shows the difference

Via the introduction of the Relative Polarity Index, the
authors show that the choice of emollients in cosmetic
formulations determines the total amount of skin
penetration of active ingredients whereas the choice of
the emulsifier determines its distribution within the
skin.
