Novel cosmetic formulations containing a biosurfactant from Lactobacillus paracasei

Abstract

Cosmetic and personal care products including toothpaste, shampoo, creams, makeup, among others, are usually formulated with petroleum-based surfactants, although in the last years the consume trend for "green" products is inducing the replacement of surface-active agents in these formulations by natural surfactants, so-called biosurfactants. In addition to their surfactant capacity, many biosurfactants can act as good emulsifiers, which is an extra advantage in the preparation of green cosmetic products. In this work, a biosurfactant obtained from Lactobacillus paracasei was used as a stabilizing agent in oil-in-water emulsions containing essential oils and natural antioxidant extract. In the presence of biosurfactant, maximum percentages of emulsion volumes (EV=100%) were observed, with droplets sizes about 199nm. These results were comparable with the ones obtained using sodium dodecyl sulfate (SDS), a synthetic well known surfactant with high emulsify capacity. Moreover, the biosurfactant and emulsions cytotoxicity was evaluated using a mouse fibroblast cell line. Solutions containing 5g/L of biosurfactant presented cell proliferation values of 97%, whereas 0.5g/L of SDS showed a strong inhibitory effect. Overall, the results herein gathered are very promising towards the development of new green cosmetic formulations.

Isolasi Dan Skrining Mikroba Penghasil Biosurfaktan Dari Air Laut Yang Tercemar Minyak

“…Berdasarkan struktur molekulnya, biosurfaktan dapat digolongkan menjadi glikolipida, lipopeptida, kompleks polisakarida-protein, fosfolipida, asam lemak dan lipida netral. Struktur molekul yang variatif tersebut menjadikan biosurfaktan memiliki potensi besar untuk diaplikasikan di berbagai industri, seperti remediasi [4, 5, 6], pertanian [7], deterjen [8], biopestisida [9], kilang minyak [10,4,11,5], biomedik [12], kosmetik [13] dan lain-lain.…”

Increase in bacterial biosurfactant production by co‐cultivation with biofilm‐forming bacteria

“…Biosurfactants are produced by a wide range of microorganisms (Rahman and Gakpe 2008) and present several advantages: they are less toxic than chemical surfactants, and more biodegradable, biocompatible (Nguyen et al 2010;Franzetti et al 2012;De Oliveira et al 2017) and stable in extreme conditions of salinity, temperature and pH (Khopade et al 2012;Liwarska-Bizukojc et al 2018). The spectrum of applications includes petroleum exploration and bioremediation (Zhao et al 2018), control of biofilms and biocorrosion (Parthipan et al 2018), pharmaceuticals and cosmetics (Ferreira et al 2017), food processing (Kiran et al 2017), biopesticides (Lahkar et al 2018) and detergents (Lee et al 2018). However, the widespread application of BSF is still limited by high production costs.…”

Utilização do resíduo da casca de laranja para produção de biossurfactantes por Bacillus subtilis

“…Dentre as aplicações dos biossurfactantes se destacam a redução da tensão superficial, o poder emulsificante, transporte de hidrocarbonetos e aderência/liberação da célula de superfícies pela excreção de biossurfactantes, atividade antibiótica e biorremediação de solos contaminados [3]. Além disso, os biossurfactantes possuem baixa toxidade, podendo ser aplicado nas indústrias de alimentos, cosméticos e fármacos [4,5]; sendo classificados em glicolipídeos, lipossacarídeos, lipopeptídeos/lipoproteínas, fosfolipídeos e ácidos graxos/lipídeos neutros, além de surfactantes poliméricos e surfactantes particulados [6]. Entre os lipopeptídeos e lipoproteínas, estão a surfactina, polimixina, octapeptinas, fengicinas e iturinas, as quais possuem efeitos antibióticos e alta capacidade na redução da tensão superficial [7,8].…”
