Evaluation of Cosmetic Ingredients Impacting Human Health

Human skin is a serious problem universally, by and large in both developing as well as underdeveloped nations. Conversely, synthetic skin care or cosmetic products, fragrances and preservatives create an unexpected adverse effect towards human skins and it’s not safeguarding too. This article reviews the current available scientific literature regarding the effect of human skins by using various ingredients to make the cosmetic and fragrances product. The present paper is an attempt to provide a detailed cosmetic product ingredients description, classification, synthetic study etc.

Effects of a lotion containing probiotic ferment lysate as the main functional ingredient on enhancing skin barrier: a randomized, self-control study

There is an emergent need to develop functional cosmetic ingredients for the topical management of skin barrier function. This study aimed to investigate the efficacy of a lotion containing fermented lysates VHProbi® Mix R for enhancing the skin barrier. In vitro studies demonstrated that fermented cultures of both Lacticaseibacillus rhamnosus VHProbi® E06 (E06) and L. paracasei VHProbi® E12 (E12) had antioxidant capacity, showing promising scavenging capability for 2,2-diphenyl-1-picryl-hydrazyl. The antioxidant capacity of these strains was also demonstrated in the model of Caenorhabditis elegans. In addition, the fermented lysates of both E06 and E12 enhanced the proliferation of HaCaT cells and ameliorated the toxicity induced by Staphylococcus aureus ATCC 25923, hydrogen peroxide, and ultraviolet B radiation in the HaCaT cell models, which simulated the irritants that facial sensitive skin is exposed to. Subsequently, the ingredient VHProbi® Mix R was formulated using four kinds of fermented lysates: E06, E12, Lactiplantibacillus plantarum VHProbi® E15, and Lactobacillus helveticus VHProbi® Y21. A clinical study was conducted to investigate whether a lotion containing VHProbi® Mix R would be beneficial for people to enhance skin barrier. The participants were asked to use the investigational product for 30 days. Several indicators, including transepidermal water loss (TEWL), skin moisturization, and redness were measured at day 0 and day 30 using VISIA®-CR and CK®-MPA systems. Meanwhile, the burden of sensitive skin (BoSS) and self-assessment questionnaires were performed at baseline and endpoint of this study. The study data showed that at day 30, there was a significant decrease in TEWL (P < 0.01), redness measured by CK®-MPA (P < 0.01), and redness profile measured by VISIA®-CR compared with the baseline measurements. Skin moisturization had significantly increased after treatment with the lotion for 30 days. BoSS and self-assessment questionnaires also substantiated that the participants felt a markedly positive change in their sensitive skin. Hence, we hypothesize that applying the topical functional VHProbi® Mix R could confer effective benefits for people with sensitive skin and this represents a promising intervention for enhancing skin barrier.

Amended Safety Assessment of Mentha piperita (Peppermint)-Derived Ingredients as Used in Cosmetics.

The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of M piperita (peppermint)-derived ingredients. The Panel reviewed data relevant to the safety of these ingredients. Because final product formulations may contain multiple botanicals, each containing the same constituent(s) of concern, formulators are advised to be aware of these constituents and avoid reaching levels that may be hazardous to consumers. Industry should continue to use good manufacturing practices to limit impurities that could be present in botanical ingredients. The Panel concluded that M piperita (Peppermint) Oil, Extract, Leaf, and leaf-derived ingredients are safe in cosmetics in the present practices of use and concentration when formulated to be non-sensitizing, and that the available data are insufficient for determining that M piperita (Peppermint) Flower/Leaf/Stem Extract, M piperita (Peppermint) Flower/Leaf/Stem Water, and M piperita (Peppermint) Meristem Cell Culture are safe under the intended conditions of use in cosmetic formulations.

Preparation of high content collagen peptides and study of their biological activities

Collagen peptides play an important role in the increasing use of collagen peptides as dietary supplements in food and beverages and as bioactive ingredients in cosmetics, healthcare, and pharmaceuticals. Collagenase enzymatically cleaves gelatin to produce collagen polypeptides. However, the enzymatic activity of collagenase is very low (25900 U) and does not allow for adequate enzymatic digestion. Therefore, proteases are used to assist in enzymatic digestion. Porcine gelatin, bovine gelatin, and fish protein gum were enzymatically digested, and the content of collagen peptides in the enzymatically digested lyophilized powder was identified by high-performance liquid chromatography and mass spectrometry, and then the content of the desired collagen peptides was increased by isolation and purification, and the result of the determination was that the content of collagen peptides was the highest after enzymatic digestion and isolation and purification with the use of porcine gelatin as the raw material, and the content of the collagen peptides was about 45.47%. β-nicotinamide mononucleotide (NMN) was mixed with the prepared samples to determine its antioxidant properties and ability to promote the growth of human dermal fibroblasts. The results showed that the antioxidant capacity was enhanced with the increase of collagen polypeptide content, and NMN could promote the scavenging of DPPH• and •OH free radicals by collagen polypeptides. The ability to promote the growth of human dermal fibroblasts was enhanced with the increase of collagen polypeptide content. This paper aimed to prepare a high content of collagen polypeptides from three raw materials, porcine gelatin, bovine gelatin, and fish protein gum, and further to determine the biological activities.

Solvent and Crystallization Effects on the Dermal Absorption of Hydrophilic and Lipophilic Compounds

This study probes the mechanisms by which volatile solvents (water, ethanol) and a nonionic surfactant (Triton X-100) influence the skin permeation of dissolved solutes following deposition of small doses onto unoccluded human skin. A secondary objective was to sharpen guidelines for the use of these and other simple solvent systems for dermal safety testing of cosmetic ingredients at finite doses. Four solutes were studied – niacinamide, caffeine, testosterone and geraniol – at doses close to that estimated to saturate the upper layers of the stratum corneum. Methods included tensiometry, visualization of spreading on skin, polarized light microscopy and in vitro permeation testing using radiolabeled solutes. Ethanol, aqueous ethanol and dilute aqueous Triton solutions all yielded surface tensions below 36 mN/m, allowing them to spread easily on the skin, unlike water (72.4 mN/m) which did not spread. Deposition onto skin of niacinamide (32 μg·cm−2) or caffeine (3.2 μg·cm−2) from water and ethanol led to crystalline deposits on the skin surface, whereas the same amounts applied from aqueous ethanol and 2 % Triton did not. Skin permeation of these compounds was inversely correlated to the extent of crystallization. A separate study with caffeine showed the absence of a dose-related skin permeability increase with Triton. Permeation of testosterone (8.2 μg·cm−2) was modestly increased when dosed from aqueous ethanol versus ethanol. Permeation of geraniol (2.9 μg·cm−2) followed the order aqueous ethanol > water ∼ 2 % Triton >> ethanol and was inversely correlated with evaporative loss. We conclude that, under the conditions tested, aqueous ethanol and Triton serve primarily as deposition aids and do not substantially disrupt stratum corneum lipids. Implications for the design of in vitro skin permeability tests are discussed.

Plant diversity and its potential in Sumenep, East Java, Indonesia

It is well known that biological and cultural diversity in Indonesia is quite high, as well as the potential of plants as food, medicine, cosmetics, and dyes. This diversity gives rise to local knowledge in its interaction with the environment and the utilization of plant resources to the daily needs of local communities. The Local knowledge from a fairly diverse community still has much to be revealed. Similarly, Sumenep geographically consists of the mainland (54.79%) and the islands (45.21%) with 126 islands. Several field surveys in Sumenep have been conducted on several islands such as in Sepanjang, Gili Iyang, Poteran, Kangean, and Madura mainland, with interview methods to the majority of Madurese ethnic people. From the data collection so far, approximately 173 potential species of plants for food, medicinal ingredients, cosmetic ingredients, and coloring materials have been recorded. Food materials include Amorphophallus paeoniifolius, Moringa oleifera, Dioscorea alata, and Borassus flabellifer, as well as medicinal ingredients include Azadirachta indica, Curcuma aeruginosa, and Paederia foetida, whereas for natural dye is Ceriops tagal.

Preparation of novel adsorptive membrane using spent spices waste-derived biochar to treat synthetic wastewater

This research work focuses on the development of biochar-infused polymeric mixed matrix membranes, where the biochar is derived from spent spice wastes. While essential oils and fatty acids extracted from spices are used as main ingredients in food items, cosmetics, and pharmaceuticals, the leftover spent spice waste is discarded in landfills. Potentially, the biochar derived by utilizing this spice waste can be used to remove pollutants from industrial wastewater. Although there is literature that uses this biochar to adsorb pollutants, very few investigate adsorption by trapping biochar in a polymer matrix. Here, we test the waste-derived biochar-polymer mixed matrix membranes (MMM) to remove dyes from wastewater to develop a circular economy. Biochar is prepared by pyrolyzing the mixture of spent spices at 350 °C, and then activating it thermally and chemically to increase the surface area available for adsorption, as seen in the FESEM images. It is then mixed with PMMA solution and spin-coated on an inert substrate. The deposited mixed matric membrane is peeled off the substrate and exposed to synthetic wastewater in a vacuum filtration setup. We conclude that not only is the adsorption efficiency of the MMM method comparable within 10% of dye removal efficiency to the batch method, it is also significantly faster and has the potential to continuously treat large volumes of wastewater.
