improves the quality of cosmetic products while reducing the reliance on preservatives. Iscaguard PEHG is permitted worldwide for use in both leave-on and rinse-off personal care products. Under the Cosmetic Regulation, it can be used in cosmetic formulations up to a maximum concentration of 1.11 %. This ingredient is particularly suitable for emulsions, oil and surfactant based formulations and may be used in aqueous formulations up to its solubility limit of approximately 1.0 %. Iscaguard PEHG can be added to the
formulation at temperatures up to 80 ºC, prolonged heating at elevated temperatures is not recommended. It is effective at a pH range of 3 - 9. In response to the industry’s growing
concern over the toxicity of preservatives used in today’s personal care and cosmetic products, Jeen has developed Jeecide AA and Jeecide AA Plus. Both are highly functional, efficacious, easy to use, and non- toxic.
Jeecide AA Series is a globally-approved
broad spectrum line of preservatives. Jeecide AA and Jeecide AA Plus are proven effective against bacteria, yeast, and mould. Jeen has substantiating challenge test data proving their efficacy. These ingredients can function across a
broad pH spectrum - from 2-7. It is recommended to adjust the pH of the formulation/system just prior to the addition of either Jeecide AA or Jeecide AA Plus. Jeecide AA is an easy to use liquid blend of benzyl alcohol, benzoic acid, and sorbic acid formulated in balance to meet the preservation needs of personal care products from shampoos and conditioners to skin care serums as well as most creams and lotions. It is particularly useful in natural and organic formulations due to the wide acceptance of the three components comprising the product. Jeecide AA can function across an enhanced pH spectrum vs. any of the three ingredients separately. The balanced ratio creates synergistic improved performance as a preservative blend across a wider pH range than typical limited acidic systems. Both Jeecide AA and Jeecide AA Plus function across a pH range of 2 - 7. Jeecide AA functions as a broad spectrum antimicrobial agent by utilizing the benzyl alcohol as a bactericide in controlling Gram-negative bacteria while the balanced benzoic acid and sorbic acid work at controlling and suppressing the growth of bacterial organisms and spore germination. Jeecide AA can be used in both rinse-off and leave-on products at a concentration of 0.5% to 1.1% depending on the final pH of the end product’s system. It is recommended to be added near the end of the formulating process along with final dyes, fragrance masks, sunscreens, and perfumes. The pH of

the end system/formula is recommended to be adjusted just prior to the addition of Jeecide AA for best solubility and to ensure that no singular component in the system can influence the pH of the end product. Inclusion of Jeecide AA earlier in the formula is possible, but not recommended. All components of Jeecide AA are widely used preservation agents and are accepted and endorsed in most natural and organic products and programs. Jeecide AA has carefully balanced ratios which optimize the performance and create additional synergies for improved function at a wider pH spectrum. Lonza offers a comprehensive range of
preservation systems and a wide-ranging portfolio of single active and blended preservatives that encompass traditional and non-traditional chemistries. One example is the Geogard Ultra
preservative. It is Ecocert- and Soil Association- approved, Cosmos- and Natrue-certified and Vegan-compliant. In addition, responding to the market demands of Southeast Asian countries such as Indonesia, Geogard Ultra preservative is also Halal-certified. The technology is multifunctional, offering
formulators a complementary moisturisation benefit in addition to broad-spectrum antimicrobial performance. Lonza’s full Geogard product line offers
wide formulation latitude and a range of pH tolerances. The Geogard product line comprises single-active and blended preservatives that deliver broad-spectrum product protection and viable alternatives to traditional chemistries.
Multifunctionals can be viewed as either standalone systems that offer a preservation effect in addition to a primary benefit or as potentiators that boost the activity of existing actives. Lonza has a programme to synthesize and evaluate new active ingredients. Whatever happens regarding market and regulatory requirements, Lonza will be able to offer solutions that are sustainable and as future-proof as possible. Formulators of personal care and cosmetics
products understand the performance advantages of broad-spectrum preservatives. While these products provide protection against both bacteria and fungi, suppliers typically offer a ‘one size fits all’ solution. The
result is poor cost performance, because personal care manufacturers are forced to pay for either extra bactericide or extra fungicide. To address this market need, Troy Corporation introduced its line of TroyCare Customized Preservative Solutions developed specifically for personal care and cosmetics applications. With the expanding portfolio of TroyCare Customized Preservative Solutions, formulators can now select a customized broad-spectrum preservative in a choice of chemistries and active ratios with the optimum levels of bactericide, fungicide, and boosting agents for their formulations, yielding the lowest total preservative cost. One of the latest additions to the line is the TroyCare EPP series, which is based on ethylhexylglycerin (EHG) and phenylpropanol. Previously introduced blends include the TroyCare FE series, which is based on IPBC and phenoxyethanol, and the PE series, which is based on EHG and phenoxyethanol. This broad selection of customized preservative solutions is globally approved for all rinse-off and leave-on formulations. Increasing regulations and heightened customer awareness continues to restrict the use of many traditional personal care preservatives. While preservative suppliers have introduced numerous milder and ‘greener’ alternatives, these often require higher use levels which can cost significantly more and create formulation challenges. More than ever, the need for customised products is becoming clear. Troy is at the forefront of this next wave of innovation. TroyCare Customized Preservative Solutions can be optimized for specific formulations or formulation types. Preservation costs can be decreased while reducing or eliminating formulating challenges.
Utilizing market-accepted ingredients with global approvals and strong safety profiles, TroyCare Customized Preservative Solutions bring greater flexibility to manufacturers, as well as custom-tailored performance and reduced cost-in-use. Growing consumer concerns about the potentially negative effects of paraben and other traditional cosmetic preservatives are driving the search for replacements. Investigations of the antimicrobial properties of epsilon-Poly-L-lysine, which is used throughout the food industry, show that it is effective against yeast, fungi and both Gram-positive and Gram-negative bacteria and yet is completely safe to humans. Having achieved GRAS status in the US, this white, crystalline solid exhibits wide pH and temperature stability and is suitable as a broad spectrum preservative in cosmetic formulations. As a world-wide supplier of this versatile
preservative for more than a decade, Wilshire Technologies offers high-purity, odorless epsilon-Poly-L-lysine in Kg, drum and larger quantities.
