Ecological soap production using green chemistry principles

The reuse of fatty materials for soap production is considered a viable alternative to minimize environmental problems such as the eutrophication of lakes and rivers and to reduce the high costs of effluent treatment and domestic water supply. This research presents protocols for ecological soap production from the determination of the saponification index (SI) using the principles of Green Chemistry. The chemical greenness of the produced soap was assessed using mass and holistic metrics. The SI measurement ensured a final product without residues, aligning with the principles of Green Chemistry: principle 1 (waste prevention) with a Factor E of 0 and an Atomic Economy of 100%. Additionally, the Green Matrix and Green Star analyses demonstrated a more sustainable experimental approach for bar soap production, with 45% higher greenness compared to traditional soap and 95% greenness for ash soap. The changes in the saponification process by the principles of green chemistry allowed ecological soap production without residues, an innocuous product to health and the environment. The methodology proposed in this research can contribute to minimizing an environmental problem related to the incorrect disposal of non-biodegradable oil.

Exploring Sustainable Manufacturing Processes for Sanitary Items Utilizing Abundant Natural Resources: A Covid-19 Pandemic Response in Northern Samar, Philippines

The COVID-19 pandemic did not only bring millions of casualties but also diminished the supply of sanitary items. In Northern Samar alone, sanitary items such as facemasks, rubbing alcohol, and soaps run out of stock on the first week of the gradual closure of businesses. This means that those with fewer financial resources have difficulties acquiring such sanitary items to protect them from this deadly disease. Northern Samar is abundant when it comes to nipa resource which has a big potential as a raw material for production of bioethanol. Due to the shortage of rubbing alcohols and raw materials for the laboratory made ethyl alcohol, extraction of bioethanol from fermented Nypa fruticans was done. This created raw materials needed in the production of laboratory made ethyl alcohol that was distributed to its target beneficiaries. On the other hand, Salacia korthalsiana Miq. commonly known as Polipog, is a traditional plant used to treat different diseases. It is used as anti-inflammatory, antiseptic, and as antibacterial agent. The root part of the plant was used to produce an antibacterial bar and liquid soap. Thru the funding of the Commission on Higher Education (CHED), manufacturing of non-medicine products took place in the University of Eastern Philippines. These basic sanitary items were given to the provincial government of Northern Samar for distribution to local communities to combat the spread of COVID-19. A prepared biosynthesized zinc oxide nanoparticles were applied to the face mask through spraying the solution on the surface of the face mask. Results showed that the textile with nanoparticles inhibited the growth of pathogenic bacteria. Further researches is sought to properly utilize the promising results of the wonders of the natural resources found in Northern Samar.

The global economy has experienced significant disruptions due to the COVID-19 pandemic, profoundly impacting production and consumption patterns. This paper examines the effect of the pandemic on consumer goods prices, focusing on a sample of hand sanitizers, soap, disinfectants, and baking yeasts. The selection of these products was motivated by multiple and comprehensive criteria, where we considered various factors such as changes in consumption patterns during the pandemic, the relevance of these products in household consumption, consumer behavior, availability of historical price data, their significance in daily domestic life, and their utility in the prevention of the disease. Employing a time-series analysis, the study investigates the relationship between product prices and the S&P 500 index, as well as the presence of structural breaks in the time series. The results reveal a significant correlation between all prices in the sample and the S&P 500 index, indicating the index's efficacy as an indicator of the overall economic state. Moreover, the study identifies a single structural break in each price time series, coinciding with the onset of the COVID-19 pandemic. Notably, hand sanitizers, soap, and disinfectants exhibit particularly substantial price jumps near the time of the break. These findings offer crucial insights into the impact of the COVID-19 pandemic on consumer prices, which can guide policy decisions aimed at mitigating the pandemic's economic consequences.

Application of Saponins from Ambon Banana Petiole (Musa paradisiaca var. sapientum L.) as Natural Surfactants in Bio-Hand Soap

Surfactants are commonly use as a foaming agents contained in soap products. Consequently, the type of surfactant used is a synthetic product that is difficult to degrade by nature fate. In addition to environmental problems, prolonged use of these products can cause health problems, such as irritation in the form of dry, scaly, itchy skin, to red rashes. Synthetic surfactants used in industry are also petroleum derivatives. This fact makes the sustainability of the industry threatened due to the increasingly critical oil reserves. Based on these problems, it is important to study alternative synthetic surfactants that are more environmentally friendly, safe for health, and abundantly available in nature. In this study, the potential of saponins from the petiole of the Ambon banana (Musa paradisiaca var. sapientum L.) was studied as a natural surfactant in hand soap (bio-hand soap). The purpose of this study was to study the effect of the variable concentration of ethanol solvent and immersion time on the amount of saponin extract yield and the formulation of bio-hand soap. The results showed that the highest extract yield of Ambon banana petiole extract could be achieved using ethanol solvent at a concentration of 80% and a maceration time of 48 hours. Based on the quality tests on bio-hand soap products that have been carried out, formula 1 (20% saponins), 2 (30% saponins), and 3 (40% saponins) have color, shape, anti-bacterial agent, and pH values that are following SNI 2588:2017. The formula that is considered the most optimum for the production of bio-hand soap is Formula 2. This is based on the highest foam stability value, which is 67.56%.

Revisiting the role of total fatty matter in soap bars

AbstractMore than 10 million tonnes of metal salts of fatty acids are manufactured worldwide every year, to create a range of soft condensed‐matter cosmetic products such as bar soaps, liquid washes, deodorant sticks, skin creams, toothpastes, and so on. These salts, popularly known as soaps, mainly use palm or tallow‐based oils as the source of fatty acids. Soap bars comprised of more than 80% soaps alone account for a significant part of the global oil/fat footprint in non‐edible usage. The COVID pandemic highlighted the need for hygiene and germ protection, thereby driving the consumption of soap bars further. Providing these personal hygiene assets to all strata of society while minimizing the negative impact on the environment through increased material consumption is a critical challenge faced by the soap industry today. Considerable research is ongoing toward making more sustainable soap bars by reducing the use of oils/fats without compromising the sensory and functional performance. Another challenge faced is that in many geographies, soap bars must comply with regulatory standards which mandate minimum levels of oils/fats (called TFM—total fatty matter) in the product with no reference to the performance or benefits provided. What this paper will demonstrate is that there are technologies to manufacture soap bars that meet the desired product performance independent of the level of TFM. These technologies have the potential to provide formulation flexibility and environmental benefits by opening the ingredient space and cutting down significantly on greenhouse gas emissions through reduced consumption of oils.

Karakteristik dan Efektivitas Formula Sabun Cuci Tangan Cair Handmade dalam Menurunkan Angka Kuman

This study aims to compare the characteristics of the handmade liquid hand soap formula and its effectiveness in reducing the number of germs. The formulation used is the difference in the amount of EDTA, Texapon, and NaCl used in soap making. The characterization carried out was organoleptic, physical stability at room temperature, pH, viscosity, foam height and stability, water holding capacity, and density. Meanwhile, reduced number of germs was carried out by calculating the total plate number (ALT) of bacteria on the test taker hand before and after washing their hands. The results obtained were that the first formula (P1) which used less amounts of EDTA, Texapon, and NaCl had a bright color, lack of foam, perfect solubility,stable at room temperature, and did not cause a burning feeling in the hands. Whereas the second formulation (P2) with a higher amount of EDTA, Texapon, and NaCl hadexellence in the amoont of foam compared to the previous formula but the solubility was not perfect, less stable at room temperature and caused a burning feeling in the hands. The result of Pairef t test show that the t count is bigger than t table, so the different formulation had an effect on reducing the germ on the test taker hand based on ALT germ number parameter. P1 formulation can reduce the number of bacteria on hands by 47.64% and P2 formulation by 36.12%.

Differentiable Physics Simulation of Dynamics-Augmented Neural Objects

We present a differentiable pipeline for simulating the motion of objects that represent their geometry as a continuous density field parameterized as a deep network. This includes Neural Radiance Fields (NeRFs), and other related models. From the density field, we estimate the dynamical properties of the object, including its mass, center of mass, and inertia matrix. We then introduce a differentiable contact model based on the density field for computing normal and friction forces resulting from collisions. This allows a robot to autonomously build object models that are visually and dynamically accurate from still images and videos of objects in motion. The resulting Dynamics-Augmented Neural Objects (DANOs) are simulated with an existing differentiable simulation engine, Dojo, interacting with other standard simulation objects, such as spheres, planes, and robots specified as URDFs. A robot can use this simulation to optimize grasps and manipulation trajectories of neural objects, or to improve the neural object models through gradient-based real-to-simulation transfer. We demonstrate the pipeline to learn the coefficient of friction of a bar of soap from a real video of the soap sliding on a table. We also learn the coefficient of friction and mass of a Stanford bunny through interactions with a Panda robot arm from synthetic data, and we optimize trajectories in simulation for the Panda arm to push the bunny to a goal location.
