1,2-Alkanediols for Cosmetic Preservation

Straight chain 1,2-alkanediols are multifunctional ingredients with moisturizing and antimicrobial activities. Here, the authors examine the ability of these materials to boost the activity of preservatives and to provide broad-spectrum antimicrobial activity. In addition, the authors describe how to combine these compounds into formulations to optimize stability and efficacy.

Jeen Combines Organic Acids and Boosters for Alternative Preservation

Jeen International Corp. has combined organic acids and efficacy boosters in a glycerin base to offer formulators an alternative to traditional preservatives.

Natural Preservation from Concepts in Nature

Chemical defense mechanisms used in the plant kingdom are the basis of natural antimicrobials with multifunctionality for preservation of cosmetic formulations. Two examples are organic acids and glyceryl monoesters.

Preserving Formulations Containing Alkyl Polyglucosides

The June 2008 issue of Cosmetics & Toiletries magazine featured an article from Cognis on the mildness of alkyl polyglucoside (APG) surfactants. The article stimulated the comments from readers and some of the questions are answered here.

Cracking Controversy
