good formulation compatibility and broad pH applicability.
According to Ashland, it can be added to formulations at any phase
when worked into products at ambient temperature. Typical uses
include body and skin care emulsions, sun care, shampoo, body
washes, conditioners and wet wipes.
Not everyone balks at traditional chemistries that have served the
category well for decades.
“Some years back, many producers were seeking a paraben-free preservative system; I believe that the broad spectrum success of parabens has proven the test of time and Protameen is
supplying more parabens to the market now than we had some
five years ago,” Manny Balsamides, Jr. of Protameen told Happi.
The company’s three main parabens are methyl, propyl, and butyl,
which all deliver cost effectiveness and proven efficacy.
“Parabens are making a comeback which indirectly means the
acceptance of parabens in the market,” Balsamides said.
Additionally, he suggested formulators consider two preservatives that are under-utilized and of natural origin: potassium sorbate and sorbic acid.
The category needs to offer multiple choices so formulators
can keep their products safe and answer consumer sentiment.
“The committed preservative supplier needs to be flexible and
have a number of options to play in the space,” Phil Hindley, head
of global marketing preservation, told Happi, pointing to Lonza’s
deep expertise, global reach and stable of products that ranges
from BIT-driven Proxel for home care to Mikrokill COS for per-
sonal care products like skin care, hair care and sun care systems
to Geogard Ultra. A synergistic and patented blend of glucono-
lactone and sodium benzoate, Geogard Ultra has proven broad
spectrum activity, a wide range of global regulatory approvals
and broad formulation compatibility, added skin moisturization
benefit and conforms to Ecocert/Cosmos, Natrue and the Soil
Companies like Lonza remain fully committed to preserving the future of, well, preservatives. In fact, Happi interviewed
Hindley just ahead of his presentation on that topic at the World
of Wipes in Nashville, TN.
“If people want a sustainable preservation industry within
home and personal care, then it needs to be done at collaborative level—suppliers, NGOs, etc.,”said Hindley, adding that stakeholders must defend existing actives and work with NGOs and
regulators to influence and drive innovation.
Sedlwicz of schülke also called for the sector to standup for
“In general, the personal care industry needs to do a much
better job in supporting the safety and efficacy of preservatives in
our products. It is far too easy to take the latest internet scare or
trend and turn that into a marketing claim of“this-free” or“that-
free,”she added.“As an industry, we need to stop this negative ad-
vertising and promote the good things that our products do. This
includes how the use of appropriate preservation methods keep
our products safe to use, even stored in a warm, moist bathroom
for months or years.”
If there’s a silver lining that’s come from all of the scrutiny
around preservatives, it could very well be greater collaboration
between suppliers, formulators and end product suppliers that
has led to NPD and will drive further advancements.
“Consider how many of the“new” go-to products from the
last seven to 10 years have already fallen out of favor with many
consumers and watch groups,” said O’Keefe of Coast Southwest.
“There is a mutual opportunity as formulators seek new technology and dozens of producers race to meet the demand. It’s a
healthy market where all parties stand to gain from the shared
objective of giving consumers what they want.”•
• The deadline for the Green Chemistry & Commerce Council (GC3)
global competition to identify and award prizes to innovators with promising, safe and effective preservative systems for cosmetics, personal
care and household products is fast approaching on Aug. 24, 2017.
The competition is sponsored by group consumer product companies, retailers, chemical suppliers, an NGO and a government agency—Biryanis, Beautycounter, Beiersdorf, Colgate-Palmolive, Johnson &
Johnson (J&J), Method – People Against Dirty, Procter & Gamble (P&G),
Reckitt Benckiser (RB), SC Johnson, Unilever, Target, Walmart, Dow
Microbial Control, Lonza, Schülke, Thor, Environmental Defense Fund
and the Minnesota Pollution Control Agency.
The corporations in the project seek to partner with innovators to
co-develop, license or invest in new technologies to speed them to
market. The competition will award cash prizes from the $175,000
prize pool, with a minimum single prize award of $25,000. Specifically,
the sponsors are looking for submissions of broad spectrum or single
action chemical agents that are effective on gram-positive bacteria,
gram-negative bacteria, yeast, and mold; preservative boosters and
multi-functional ingredients that have a primary non-preserving function, yet enhance antimicrobial efficacy.
Up to five finalists will be invited to present their technologies at
a meeting in the first quarter of 2018 in the US and to network with
representatives from consumer product companies, major retailers,
and preservative suppliers. According to the group, all innovators who
submit to this competition will gain significant visibility and receive feedback on their technologies.
