Abstract
According to the present invention, there is provided a cosmetic composition comprising a cosmetically acceptable carrier and a preservative system, wherein the preservative system comprises (i) an antimicrobial agent; (ii) a chelating agent comprising ethylenediamine tetraacetic acid (EDTA) or a derivative thereof; and (iii) an antimicrobial booster agent selected from the group consisting of ethylhexylglycerin, caprylyl glycol, hydroxy acetophenone, caprylhydroxamic acid, phenethyl alcohol, p -anisic acid, glyceryl caprylate, levulinic acid, sodium levulinate, propanediol, hexanediol, pentylene glycol, capryloyl glycine, methylpropanediol, phenylpropanol, sodium anisate, and combinations thereof, and the antimicrobial agent is present in an amount of from about 0.001% to about 1% by weight of the composition.
Description
technical field [0001] The present invention relates to novel preservative systems and the use of these systems in cosmetics. Background technique [0002] Microbial contamination of cosmetic products is a problem and is a major cause of product recalls and financial loss to the industry. Cosmetic products are ideal substrates for the survival and development of various microorganisms as they possess water and many nutrients that promote their growth 1 . [0003] The presence of certain microorganisms in cosmetic products poses a health risk to consumers, for example, in the form of skin irritation, allergic contact dermatitis and infections, especially in the eyes, mouth or wounds. Furthermore, the presence of microorganisms may negatively affect sensory properties, eg, odor, viscosity and color of cosmetic products. [0004] The use of preservatives capable of reducing the microbial load to acceptable levels improves the microbiological quality of cosmetic products. Re...
