The pallet of preservatives for formulators to choose from is rapidly decreasing. Taking advantage of innovative antimicrobial delivery systems, we have developed preservative solutions based on nature identical active ingredients that provide excellent antimicrobial protection while keeping the level of the actives as low as possible.

An insight into a scrutinised industry / Ben Elmadi in GLOBAL PERSONAL CARE, Vol. 22, N° 5 (05/2021)  

[article]  inGLOBAL PERSONAL CARE > Vol. 22, N° 5 (05/2021) . - p. 33-34 Titre : An insight into a scrutinised industry Type de document : texte imprimé Auteurs : Ben Elmadi, Auteur Année de publication : 2021 Article en page(s) : p. 33-34 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Conservateurs (chimie) Cosmétiques -- Conservation Index. décimale : 668.5 Parfums et cosmétiques Résumé : Preservatives are vital for all aqueous formulations, but the range of options is limited. MSL presents an overview of the current situation. Preservatives are defined as “substances which are exclusively or mainly intended to inhibit the development of micro-organisms in the cosmetic product”. Natural or synthetic ingredients, they are added to a wide range of products, from foods to pharmaceuticals, to prevent spoilage – whether from microbial growth or undesirable chemical changes. They are essential in personal care and cosmetic products to stop products being damaged by microorganisms and to protect the product from inadvertent contamination by the consumer during use. Acting as the antibiotics of the cosmetic industry, they keep products from developing unsightly changes or spoiling, as well as protecting consumers themselves. Without them, cosmetics would have a much shorter shelf life, which would ultimately impact day to day skin care and beauty routines. For example, without preservatives, users could not take their favourite makeup or daily moisturising cream away on holiday with them. They also help to reduce the amount of packaging required, as they enable products to be sold as multi-use instead of single use doses. To safeguard health and safety, there are stringent rules in place. The EU Cosmetic Regulation requires that all cosmetic products be safe for human health and preservatives within them must be listed on Annex V.1 Currently there are 60 preservatives on the EU list but only a limited number are in common use and many of those are facing regulatory review and uncertainty. It is clear, then, that preservatives are valuable – so why are they the subject of so much contention and debate?

Assessment of preservation challenges and solutions / Jennifer Hermitage in PERSONAL CARE EUROPE, Vol. 8, N° 3 (04/2015)  

[article]  inPERSONAL CARE EUROPE > Vol. 8, N° 3 (04/2015) . - p. 73-75 Titre : Assessment of preservation challenges and solutions Type de document : texte imprimé Auteurs : Jennifer Hermitage, Auteur Année de publication : 2015 Article en page(s) : p. 73-75 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Conservateurs (chimie) Cosmétiques Cosmétiques -- Conservation Iodopropynyl butylcarbamate conservateurs autorisés en cosmétique, établie par la réglementation européenne. Index. décimale : 668.5 Parfums et cosmétiques Résumé : Preservation is a vital part of any personal care formulation. We require preservatives to protect our products from the effects of bacterial, yeast and fungal growth. Selecting the correct system to perform this task is not a simple process — many factors will need to be considered before the correct choice can be made. The system must not only be robust enough to ensure that a finished product is sterile when first made, but also that it minimises risk of contamination right up to the expiry date. In this paper, we will discuss the challenges faced by cosmetics chemists when evaluating preservation options. Regulatory pressures, consumer perception and the abundance of new and conflicting studies of varying degrees of scientific credibility make preservation selection increasingly complex. We will discuss recent trends, some of which are promising, while others, such as non-preservative alternatives, may actually pose greater risk. We will also explore the advantages of IPBC (iodopropynyl butylcarbamate) as a preservative, whether used as the sole active or as part of broad-spectrum blends, some of which offer unique benefits in the marketplace.

Combination of lactic acid with 1,2-hexanediol - a new possibility to stabilise rinse-off formulations / Katja von Nessen in SOFW JOURNAL, Vol. 146, N° 4 (04/2020)  

[article]  inSOFW JOURNAL > Vol. 146, N° 4 (04/2020) . - p. 22-25 Titre : Combination of lactic acid with 1,2-hexanediol - a new possibility to stabilise rinse-off formulations Type de document : texte imprimé Auteurs : Katja von Nessen, Auteur ; Felix Weiher, Auteur ; martin Neubauer, Auteur ; Thomas Kerl, Auteur ; Judith Preuschen, Auteur Année de publication : 2020 Article en page(s) : p. 22-25 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : 1,2-hexanediol Antimicrobiens Cosmétiques -- Conservation Dermo-cosmétologie Formulation (Génie chimique) Lactique, Acide L'acide lactique est un acide organique qui joue un rôle dans divers processus biochimiques. Un lactate est un sel de cet acide. Contrairement à ce que peut laisser penser son nom, l'acide lactique n'est pas présent uniquement dans le lait, mais également dans le vin, certains fruits et légumes, et dans les muscles. L'acide lactique est un acide alpha hydroxylé, sa formule chimique est C3H6O3 et sa structure se reflète dans son nom systématique, l'acide 2-hydroxypropanoïque. Laureth sulfate de sodium Peau -- Soins et hygiène Savon liquide Stabilisants (chimie) Tests d'efficacité Index. décimale : 668.5 Parfums et cosmétiques Résumé : In recent years the demand from consumers for natural preservation systems for personal care products has increased significantly. Since many preservatives are not sufficiently effective against all microbes when used alone, more and more often a combination with preservation boosters such as 1,2-hexanediol is required. One well-established natural preservative is lactic acid, which is known to reduce bacteria in aqueous systems. In this study, preservation stress tests according to the European Pharmacopeia (Ph. Eur. or EP) were carried out for single ingredients and combinations of lactic acid with 1,2-hexanediol in an aqueous solution of sodium laureth sulfate (SLES) as a basic system. Sufficient preservation of the basic system could not be achieved with the individual substances alone. In contrast, in combination the two showed a synergistic effect and the test was passed. This synergistic effect of the combination of lactic acid and 1,2-hexanediol was verified in a shower gel formulation.
