Investigation and Characterisation of New Eco-Friendly Cosmetic Ingredients Based on Probiotic Bacteria Ferment Filtrates in Combination with Alginite Mineral

Abstract

In light of the fact that three of the five healthiest meals on earth are fermented, fermentation came into focus of both customers, product developers, and researchers all around the world. Even in the cosmetics industry, fermented cosmetics have been increasingly introduced, creating a market emphasising the positive image that healthy fermented substances are environment-friendly and that it also aids skin health. Moreover, discovering usages for various naturally occurring organo-mineral rocks is a growing area of research. Thus, this study’s aim was to combine the benefits of alginite and Lactobacilli (LAB) for cosmetic applications and investigate their combined effect on the skin considering the fermentation parameters as well, such as biomass and lactic acid concentration. The examined LAB strains were Lactobacillus rhamnosus, Lactobacillus acidophilus, Limosilactobacillus reuteri, and Lactococcus lactis, and a non-LAB probiotic strain Bifidobacterium adolescentis was also studied for the same purposes. The cell-free broth, also called as “filtrates”, of the fermentations—both those that included alginite and those that did not—were tested for skin moisturising with a corneometer and for antioxidant activity with DPPH scavenging, as well as for skin-whitening properties with the inhibition of mushroom tyrosinase. The findings suggest that the combination of alginite and Limosilactobacillus reuteri is a potential novel cosmeceutical component with skin tanning capabilities. This result may help create more readily available, environmentally friendly, natural, and sustainable cosmetic ingredients.

“…The results corroborated with other studies that used alginate-based formulations to deliver LAB [ 46 , 47 ]. The alginate-based formulations provide protection, a controlled release of active principles, and better formulation stability [ 48 , 49 , 50 , 51 , 52 , 53 ].…”

Investigations on Applied Microbiology Regarding Carbon Capture, and Fermentative Production of the Ingredients in Sweeteners, Agricultural Biosurfactants and Cosmetics

“…However, we encountered unexpected results regarding mushroom tyrosinase inhibition. The alginite-based filtrates showed an increase in this activity, while the filtrates without alginite inhibited the enzyme, suggesting that these ferment filtrates contribute to skin browning [24].…”

Investigations for a Yarrowia-Based Biorefinery: In Vitro Proof-of-Concept for Manufacturing Sweetener, Cosmetic Ingredient, and Bioemulsifier

“…Short-term skin moisturising measurements were performed after treatments on 1 × 1 cm 2 European human adult skin with the samples. The determination of skin moisture was carried out with the Multi Dermascope MDS 800 (Diepoldsau, Switzerland), as reported earlier by Tóth et al [47], using the Corneometer of the equipment. After treatments, skin moisture content increased, decreased via the loss of excess humidity, and then finally stabilized.…”
