Recent in Preservatives (page 3 of 6)


Efforts toward preservation are more than a trend, they are an essential component of the inner workings of our industry. Consider how much of the world has recognized this and joined in adopting sustainable and eco-friendly practices and it becomes obvious. In the words of writer Samuel Butler, “Self-preservation is the first law of nature.”

Parabens: Myth and Reality

This review offers an in-depth look at one of the most controversial scientific studies of recent years and explores the relevance of the results of this study and other selected studies to the current layman’s perception of the safety of parabens.

Optimizing Formula Preservation

To ensure that a consumer-ready product is safe, an appropriate preservation strategy must be established for the development, manufacture and packaging of the formula, thus eliminating unacceptable levels of organisms such as pathogenic bacteria, fungi and mold that could grow and pose a health hazard to the consumer.

Broad-spectrum Alternative to Caprylyl Glycol Preservative Blends

Symrise has added a broad-spectrum preservative to its cosmetic ingredients offering that is said to serve as an alternative to caprylyl glycol blends.

Ethyl Lauroyl Arginate HCl for Natural Preservation

Ethyl lauroyl arginate HCl (LAE), derived from natural lauric acid and L-arginine, is shown here to provide broad-spectrum activity against microorganisms including Malassezia furfur and Propionibacterium acnes. In vitro tests corroborated by in vivo evaluations suggest its efficacy in anti-dandruff and dermo-purifying applications.

The Required D-Value: Evaluating Product Preservation in Relation to Packaging and Consumer Use/Abuse

Cosmetic and pharmaceutical products are subject to microbial contamination and spoilage during use. In 1970, Halleck published the recommendations of the Preservation Subcommittee of the Toiletry Goods Association Microbiology Committee, which stated that preservation studies should consider product formulation, manufacturing conditions, packaging, product stability and continued effectiveness of the preservative system during the intended use by consumers.

Ingredient Profile—Benzoic Acid/Sodium Benzoate

Benzoic acid (BA) is a leading choice due to its long and successful history of use preserving foods, drugs and cosmetics. Affirmed as GRAS (Generally Recognized As Safe) by the US Food & Drug Administration (FDA), BA and its sodium salt, sodium benzoate (NaB), are perhaps the most globally acceptable preservatives that have managed to avoid the controversy associated with many of the industry’s tried-and-true preservatives.

"Nature-identical" Preservative for More Sustainable Science

"Nature-identical" phenethyl alcohol was used to create schülke's sensiva® PA 20 (INCI: Phenethyl Alcohol (and) Ethylhexylglycerin). Phenethyl alcohol occurs widely in nature and has properties that help maintain the microbiological stability of personal care formulas.

Kemin Personal Care Debuts With Natural Soy Preservative

Boosting Preservative Efficacy With Propanediol

This article investigates the ability of Zemea (INCI: Propanediol) to boost preservative efficacy in an aqueous personal care formulation. This 100% bio-based propanediol is a colorless, pure glycol alternative derived from a sustainable, renewable corn fermentation process. The testing was conducted using standardized microbiology guidelines, known as preservative efficacy testing or challenge tests.

Formula Troubleshooting—Preservation

Cosmetics & Toiletries magazine is pleased to add this new “Formula Troubleshooting” column to the regular lineup. Led by column editor Peter Tsolis of The Estée Lauder Companies, it will cover some of the more common formulation challenges and suggest solutions for the benefit of novice formulators and as a refresher for seasoned experts.

Comparatively Speaking: Toxicity vs. Selective Toxicity

In the present "Comparatively Seaking" column, industry expert Anthony J. O'Lenick explains the difference between toxicity and selective toxicity in regard to preserving a personal care formula while also keeping the consumer safe.
