over use of other ingredients to compensate, like surfactants and emulsifiers, which can have their own negative effects of de-fatting and drying out the skin.

“We are all trying to avoid any product contamination and the less effective preservatives we use, the greater the potential,” he said.

Pat Lutz, president of Lincoln Manufacturing Inc., noted that it is a challenge to find all-natural or naturally-derived preservatives that are broad spectrum and cost effective like conventional preservatives. Lincoln says its new Linatural MBS ( microbial blocking systems) are naturally-derived, inexpensive, preservative-free systems that block microorganisms from growing, thus keeping the formulation stable.

“These systems give the customer the
option for a cost effective alternative to
preservatives that block a broad spectrum
of microorganisms from contaminating
the formulation while the customer can
claim preservative-free and no oils,” Lutz
explained.

ever-shrinking number of well-accepted actives is the biggest limiting factor for the preservative market. She said that schülke’s expertise is in the development of innovative blends of available materials with antimicrobial properties.

“As the list of traditional preservatives
at our disposal has become severely limited,
we have focused our attention on more
multifunctional materials,” said Sedlewicz.
“Our most recent introduction, sensiva PA
20, is the result of our research into nature-
identical materials.”
According to Sedlewicz, sensiva PA 20
combines phenethyl alcohol, traditionally
used as a fragrance ingredient, with ethyl-
hexylglycerin for its preservative boosting
effect. “The result is a biodegradable blend
that can maintain the microbiological sta-
bility of a wide range of products,”she said.
