Development of 3D gingival in vitro models using primary gingival cells.

Since March 2013, animal testing for toxicity evaluation of cosmetic ingredients is banned in Europe. This directive applies to all personal care ingredients including oral ingredients. Gingival in vitro 3D models are commercially available. However, it is essential to develop "in house model" to modulate several parameters to study oral diseases, determine the toxicity of ingredients, test biocompatibility, and evaluate different formulations of cosmetic ingredients. Our expertise in tissue engineering allowed us to reconstruct human oral tissues from normal human gingival cells (fibroblasts and keratinocytes). Indeed, isolation from surgical leftover was performed to culture these gingival cells. These cells keep their endogenous capacity to proliferate allowing reconstruction of equivalent tissue close to in vivo tissue. Reconstruction of gingival epithelium, chorion equivalent, and the combination of these two tissues (full thickness) using primary gingival cells displayed all characteristics of an in vivo gingival model.

Beneficial properties of olive tree leaves concerning personal care ingredients: Herbal tincture

ABSTRACT Background: The skin is essential for our survival and daily functioning. Everyday use and constant exposure to a wide range of personal care products and different types of chemicals coming from various sources may cause serious problems. Therefore, the use of natural and organic cosmetics becomes increasingly essential. The olive tree is one of the oldest cultivated fruit trees and has been used in cosmetics for centuries. This study aimed to present a method for the easy preparation of an olive tree leaf tincture that may be incorporated into a cosmetic product and reproduced in a domestic environment. Materials and Methods: All equipment employed was cleaned and disinfected beforehand. Fresh olive tree leaves were ground to a powder. A 20% olive tree leaf tincture was made. Olive tree leaves and alcohol were mixed in a sterilized jar. The mixture was shaken daily for two weeks. Results: The pH of the olive tree leaf tincture was determined with pH stripes and was in the range of 5.5 to 6.5. This may impact how much of the tincture will be used and how it will be used. For this reason, we suggest using it at a concentration of 1%. The chosen herb-to-solvent ratio of 1:5 (w/v) yielded a concentrated tincture with enhanced potency. A higher concentration of active constituents in the tincture is expected to offer a more potent and effective form of herbal extract. Conclusion: The findings in this study supported the potential of olive tree leaves as a valuable resource for developing natural and sustainable interventions targeting DNA damage and related health conditions. Continued research in this field will contribute to a better understanding of the therapeutic potential and applications of olive tree leaves in the field of natural cosmetics and medicine.

Sorption of cosmetic and personal care polymer ingredients to iron oxides, clay minerals and soil clays: An environmental perspective

The increasing daily use of cosmetic and personal care ingredients (CPCIs) requires improved understanding of the fate and impacts of CPCIs in environmental systems. Effects of CPCIs on colloidal properties of various geocolloids such as iron oxides (goethite, haematite), clay minerals (kaolinite, bentonite) and soil clays (kaolinitic-, illitic- and lateritic soil clays) were studied by tracking time-resolved changes in zeta potential (ζ) and observing suspended particle density. Two polymers representing anionic CPCIs, i.e., polyacrylate crosspolymer-11 (PC11) and cationic CPCIs, i.e., polyDADMAC (PD) show contrast effects on ζ and colloidal properties of the selected materials. While PC11 tended to associate with Fe oxides, PD can be adsorbed by clay minerals and soil clays. The neutralization due to the sorption of either PC11 or PD onto opposite-charge sign surface sites can lower the net surface charge of the materials, thereby enhancing electrostatic attraction, stimulating particle size growth, and eventually intensifying co-aggregation. The observed colloidal properties of iron oxides, clay minerals and soil clays under the presence of PC11 and PD may reflect what are happening in many aquatic environments where CPCIs co-exist with various mineral colloids. Therein, CPCIs likely delay the transport of the opposite-charge sign colloids, while they increase the dispersibility and transportability of the same-charge sign colloids. This implies that intensifying presence of a given CPCI could have selective effects on colloid systems. As a whole, CPCIs can change the fate and the final destination of mineral colloids and themselves; therefore, their effects and relevant treatment techniques need to be included into the future agenda.

Optimizing interactions between soluble silk fibroin and capryl glucoside for design of a natural and high-performance co-surfactant system.

Because of the strong consumer driver towards more natural or higher sustainability cosmetic products, silk fibroin was evaluated to help develop a formulation with natural and effective ingredients for personal care. In order to exploit the physical properties of silk fibroin, it was evaluated to maximize the surfactant properties of other commercial ingredients to lower surface tension and build up viscosity. A synergistic effect was seen between silk fibroin and capryl glucoside, a sugar surfactant which exhibited a natural and effective co-surfactant system. This system demonstrated better surface tension properties than sodium laureth sulphate (SLES), cocamidopropyl betaine (CAPB), rhamnolipids and sophorolipids, which led to greater foamability and cleansing properties. This system proved to also be compatible with polysaccharide viscosity modifiers to enhance the viscosity of the system. The present study comprises a systematic exploration of natural formulation development of silk proteins and other natural ingredients, which result in high performance such as enhanced foam quality, foam stability and enhanced sebum removal. All of these properties are desirable and may utilized when formulating cleaners and shampoos. A force tensiometer, Attension Sigma 701, was used to measure the surface tension of the silk protein and its various combinations with biosurfactants and biopolymers. To measure bulk rheology, a traditional mechanical rheometer TA DHR-3 was utilized. Foaming tests and sebum removal assays were also carried out to evaluate the performance of the samples. Silk fibroin was evaluated to maximize the surfactant properties of other commercial systems to develop a formulation containing natural and effective ingredients for personal care. The surface activity of silk proteins was seen to be synergistically enhanced in the presence of sugar surfactants such as capryl glucoside, resulting in a surface tension at the air-water interface which is lower than either that of pure silk fibroin or pure capryl glucoside. This surface tension value is additionally lower than that obtained from currently utilized synthetic surfactants like sodium laureth sulphate (SLES) and cocamidopropyl betaine (CAPB). This reduction in surface tension demonstrated greater foamability and cleansing properties than that of the commercial systems. The very low surface tension values obtained through combinations of silk proteins and glucoside resulted in a natural and effective co-surfactant system by forming high-quality stable foams and enhancing sebum removal. The rheological performance of the silk proteins was impacted through microstructure modifications as a result of interactions with biopolymers like carrageenan. This shows that this system is compatible with polysaccharide viscosity modifiers. It was observed that both the flow curve and the absolute viscosity values were significantly impacted in the presence of carrageenan, with higher viscosity generation and significant non-Newtonian/shear thinning behaviour evolution. These results indicate that the silk fibroin can be utilized to build a high-performance natural product and significantly enhance the performance of other natural/sustainable cosmetic formulations through building synergistic interactions with other natural ingredients such as sugar surfactants and biopolymers. These properties exhibited by this system are all desirable for cleansers and shampoos within the cosmetic industry. Silk fibroin in combination with capryl glucoside outperforms other commercial surfactants that are commonly used in the industry because of its surface-active behaviour and synergy. This system is then enhanced further with polysaccharide rheological modifiers, carrageen and xanthan gum to help build up viscosity. The complex mixture of silk fibroin, sugar surfactant and biopolymer results in a formulation that is all natural, while still having high performance by achieving great foamability and enhanced sebum removal. The mixture can further be used to formulate a fully natural product such as a cleanser or shampoo while still having the same or greater effectiveness as synthetic surfactants and ingredients typically used in cosmetic formulations.

Recombinant Protein Polymers: A Coming Wave of Personal Care Ingredients.

After decades of research and development, recombinant protein polymers have begun to find applications outside the pharmaceutical and biomedical fields. Several recombinant derivatives of natural structural proteins are now being sold in personal care products, providing novel functionality while also being animal-free, not derived from petroleum, biocompatible, and biodegradable. Consumers are now demanding these material characteristics in their personal care products, and a backlog of well-characterized recombinant protein polymers could become the future of personal care ingredients.

Estimation of the Contribution Made to Down-the-Drain Emissions of D5 by Personal Care Product Categories in the European Union.

Aquatic risk assessment of personal care chemicals requires quantifying the contribution of all product types containing these ingredients to down-the-drain emissions. We developed a probabilistic model framework embracing stochastic variability associated with individual consumers and their behaviors in the European Union, as well as other sources of uncertainty related to losses following applications (e.g., volatilization). The model was applied to decamethylcyclopentasoloxane (D5), an emollient used in wash-off (WO) and leave-on (LO) products. Quantifying contributions from each product category containing D5 to down-the-drain emissions is necessary to inform optimal risk management options. Simulation results for the baseline scenario in 2012 support the argument that LO products make up a minor contribution (7.1%) to down-the-drain emissions of D5, with only 0.20% of the D5 used in LO products being released to wastewater. The most influential model parameters are the release factor from WO products and the time between application and use for various LO product types, stressing the importance of embracing stochastic variability across individuals' behavior when assessing contributions of various product types to environmental emissions. The downward trend in WO use from 2010 to 2016 is reflected in declining concentrations in wastewater influent during the same period. Uncertainty remains about future levels of D5, once phasing out WO products is complete. The probabilistic model in conjunction with high-tier data of consumer habits is a promising high-tier tool for the characterization of complex emission scenarios of personal care ingredients.

The Effect of Select Personal Care Ingredients and Simple Formulations on the Attachment of Bacteria on Polystyrene

The human body is covered with bacteria that are required for health and wellbeing. Additionally, there are pathogenic bacteria that are unwanted. It is therefore important to understand how personal care ingredients interact with these bacteria. To help understand these interactions, a high-throughput assay was developed to study the effect of personal care ingredients on attachment. Seventeen personal care ingredients were assayed singly and in simple alcohol based formulations. Three of the ingredients decreased the attachment of both bacteria tested by 90% singly and in formulation. Personal care ingredients singly and in simple formulations can prevent the attachment of bacteria. Further research is needed to better understand how personal care ingredients affect bacterial attachment and how these effects can be used to create new hygiene products for consumers.

Behind the scenes, scientifically, at In-Cosmetics

Flash and glitz are the name of the game at In-Cosmetics Global, the annual personal care ingredients show, held this year in Amsterdam. But in an effort to display the science behind the latest lotions and potions, Reed Exhibitions, organizers of the April 17–19 event, offered for the first time what they billed as exclusive R&D tours for formulation professionals. Promising a look at the most compelling ingredients and sophisticated technologies at the show, cosmetic chemist and consultant Rouah Al-Wakeel led groups of about 20 on the tours. One, for instance, focused on biotechnology-derived active ingredients. Wearing wireless headphones, the group followed Al-Wakeel through the massive RAI exhibition center, which was hosting nearly 800 exhibitors and 9,000 visitors. Some of the ingredients she highlighted offered antiaging benefits or skin protection against environmental pollutants. Along the way, Al-Wakeel introduced speakers who detailed their newest products. For instance, Guglielmo Bifulco of Kalichem
