Undecylenoyl Peg-5 Paraben, also known by its chemical name Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxo-10-undecenyl)-.omega.-(4-carboxyphenoxy)-, .alpha.hydro-.omega.-hydroxypoly(oxy-1,2-ethanediyl) esters (5 mol EO average molar ratio), is a synthetic compound primarily used in cosmetics for its antimicrobial properties. This ingredient is a member of the paraben family, which are widely recognized for their ability to prevent the growth of harmful bacteria and mold in cosmetic products, thereby extending their shelf life.
The history of Undecylenoyl Peg-5 Paraben in cosmetics dates back to the ongoing quest for effective preservatives that can ensure product safety and longevity. Parabens, in general, have been used since the 1920s, but the specific formulation of Undecylenoyl Peg-5 Paraben is a more recent innovation designed to meet modern cosmetic standards and consumer demands for effective yet gentle preservatives.
The production of Undecylenoyl Peg-5 Paraben involves a complex chemical process. It is synthesized by reacting undecylenic acid, a naturally occurring fatty acid derived from castor oil, with polyethylene glycol (PEG) and paraben. The result is a compound that combines the antimicrobial efficacy of parabens with the solubility and mildness of PEG, making it suitable for a wide range of cosmetic formulations. This synthesis ensures that the ingredient can be easily incorporated into various products without compromising their texture or performance.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Undecylenoyl Peg-5 Paraben:
Undecylenoyl Peg-5 Paraben is primarily known for its antimicrobial properties. This means it helps to inhibit the growth of microorganisms such as bacteria, fungi, and yeasts in cosmetic products. By doing so, it helps to extend the shelf life of your favorite beauty products and ensures they remain safe and effective for use over time. This is particularly important for products that are exposed to air and skin, such as lotions, creams, and makeup, as it helps to prevent contamination and spoilage.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Undecylenoyl Peg-5 Paraben is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Undecylenoyl Peg-5 Paraben during pregnancy is lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Undecylenoyl Peg-5 Paraben are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Undecylenoyl Peg-5 Paraben has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
