PRESERVATIVE MARKET UPDATE
consumers, answering marketers’
demands for“preservative-free” label
copy and fending off scientifically
unsound legislation. Keeping all
these balls in the air is quite a juggling act, indeed, but forward-think-ing suppliers are offering a range of
solutions for formulators of personal
care and household products.
Last month at In-Cosmetics,
Lonza Personal Care launched
Rômacil V, a multifunctional cosmetic ingredient that imparts a delicate
fragrance to mildly enhance the attributes of a personal care product.
In addition, it offers broad-spectrum
antimicrobial capabilities to add an
additional level of protection in order
to maintain the product’s integrity.
“Rômacil V was developed to
respond to formulators’ desires for
products that offer multiple benefits, that simplify the formulation process, and that offer consumers key desired effects,” explained Szymczak-Frye.
According to Hummel, Lonza’s current focus is to evaluate its
existing portfolio of preservation technologies and develop new
and innovative combinations that can potentially increase effectiveness while mitigating customers’ concerns.
Protameen introduced Pro-Aqua Isosteareth 200 linoleate,
which Manny Balsamides described as a unique, water-soluble
Inolex continues to launch solutions based on its multifunctional chelating agent, CHA. The most recent additions include
two systems for cold-process applications: Spectrastat OL and
“We did extensive research on their ability to preserve wet
wipes and found them to be extraordinarily effective,” explained
Winn, who added that market response has been superb.
Blends Meet Global Demands
Following the growing worldwide demand for milder and greener
cosmetic formulations, Sharon Labs developed a wide selection
of unique broad spectrum preservative solutions which provide
answers for the marketing demands and at the same time give
full protection to end products.
“Some of our new synergistic blends are based on well-known
preservative ingredients which meet global trends,” explained
Green. “Others contain ingredients that have preservative activ-
ity, yet are not listed on Annex VI, which is a list of preservatives
permitted in cosmetics sold in the EU.”
In 2012, the company launched the Sharon Biomix line and
added two new products last year. Just last month, the company
introduced Sharon Biomix Free C and Sharon Biomix Free H.
These liquid blends are based on unique natural organic citrus
extracts and do not contain ingredients which are listed on Annex
VI, according to Green. They are paraben- and formaldehyde-
free, broad spectrum, soluble in water, odorless, may tolerate
elevated temperatures, and work in a wide pH range. The rec-
ommended use level of these products is less than 1%, ideal for
leave-on and rinse-off products, according to the company. Coast
Southwest distributes Sharon’s preservatives.
At schülke, euxyl K 900 is the latest addition to its family of
boosted preservation systems. Like its sister products, euxyl PE
9010 and sensiva PA 20, euxyl K 900 uses the preservative booster,
ethylhexylglycerin, to provide a broader spectrum of preservative
activity. According to Sedlewicz, schülke’s patented stabilization
process for ethylhexylglycerin provides consistently high quality,
without the risk of color and odor changes.
“Our extensive safety dossier provides confidence that our
quality of ethylhexylglycerin can be used even in products for
sensitive populations,” she added.
With the high costs associated with developing preservative
systems, industry experts expect any new product activity to be
dominated by multifunctional blends.
“It’s too expensive to create new preservatives just for cosmet-
ics,” noted Steinberg, who pointed out that Kathon was originally
developed for the agricultural industry.“The cosmetic markets are
too small to warrant the R&D costs. Plus, there is the added cost
of product approval and then, the NGOs come after you! As soon
as a company comes out with a new chemical structure, you can
be sure that somebody will come along to tear it apart.”
With opponents like that, it’s enough to drive a formulator to
drink—perhaps something a bit more potent than light beer!•
