Detergente eco amigable: Saphi / Eco-friendly detergent: Saphi

Gadea Alcazar, Gerson Heng Fat, Hernandez Manrique, Sheyla Marianela, Mamani Jauregui, Tatiana, Nieves Canales, Janine Valeria, Rivera Albinagorta, Maria Pia 01 July 2019 (has links)
En los últimos años, se ha incrementado el interés global por salvaguardar la ecología y reducir la contaminación que tanto perjuicio causa al medio ambiente. Debido a ello, los consumidores prefieren la compra de productos que ofrezcan, además de calidad, un aporte para solucionar el macro problema de la eutrofización. Nuestro grupo, en el afán de seguir esta tendencia, ha visualizado una oportunidad de negocio, es así que propone crear Saphi que se muestra como una alternativa eco amigable a los detergentes tradicionales. Para este fin, se hará uso de una raíz de la planta llamada Saqta, la cual crece en la región Cuzco y tradicionalmente se usa como jabón natural para lavar la lana de alpaca antes de hilarla. Con la colaboración de especialistas, se pretende diseñar este artículo de limpieza bajo el nombre de Saphi (palabra que significa limpieza en quechua) y comercializarlo en envases reciclables; los cuales le darán una personalidad única al producto e identificable para el consumidor promedio. En el presente trabajo se presentará el Informe de Investigación con información cualitativa como el plan de Marketing, plan de Recursos Humanos, plan de Responsabilidad Social, validaciones, entre otros e información cuantitativa en torno al análisis financiero y de rentabilidad con el fin de introducir el novedoso artículo al mercado, documento esencial para lograr un correcto y eficaz inicio de operaciones de nuestra empresa. Es así, que podemos llegar a la conclusión que nuestro negocio es rentable, llegando a recuperar la inversión inicial en el segundo año. / In recent years, global interest has increased to safeguard the ecology and reduce the pollution that damages the environment. Due to this, consumers like the purchase products that offer, in addition to quality, an input to solve the problem of eutrophication. Our group, with the final purpose to follow this trend, has visualized a business opportunity, this is how we propose to create Saphi that is shown as an eco-friendly alternative to traditional detergents. For this purpose, a root of the plant called Saqta will be used, which grows in the Cuzco region and is traditionally used as a natural soap for washing alpaca wool before spinning. With the collaboration of specialists, it is intended to design this cleaning article under the name of Saphi (a word that means cleaning in Quechua) and to market it in recyclable containers; which will give a unique personality to the product and identifiable for the average consumer. In the present work the research report is presented with qualitative information such as the Marketing plan, Human Resources plan, Social Responsibility plan, validations, among others, and quantitative information about the financial and profitability analysis in order to introduce the novel article to the market, essential document to achieve a correct and efficient start of operations of our company. Thus, we can reach the conclusion that our business is profitable, recovering the initial investment in the second year. / Trabajo de investigación

An experimental investigation on seeded granulation of detergent powders

Rahmanian, Nejat, Halmi, M.H., Choy, D., Patel, Rajnikant, Yusup, S., Mujtaba, Iqbal M. 12 March 2021 (has links)
Yes / Granulation is commonly used as an enlargement process of particles produce granules with desirable characteristics and functionality. Granulation process transforms fine powders into free-flowing, dust-free granules with the presence of liquid binder at certain operating conditions. The main focus of this research is on seeded granulation of detergent powders, a new phenomenon of granulation in which a layer of fine powders surround the coarse particle. This is already proven for calcium carbonate (Rahmanian et al., 2011). Here, detergent granules were produced in a 5 L high shear Cyclomix granulator using different fine/coarse powder ratio (1/3, 1, 3) and different binder ratio of 10 %, 20 % and 30 %. The granules were then characterized for their particle size distribution, strength and structure. It was found that a high percentage (70 wt. %) of granules in the desired size range between 125 - 1,000 µm were produced using the powder ratio of 1/3 and a binder content of 10 %. Low mean crushing strength (3.0 N) with a narrow distribution was obtained using this condition. Structure characterization of the detergent granules produced in the granulator shows that consistent seeded granule structures are produced under the optimum process and formulation conditions of 1/3 powder ratio with 10 % binder.

Regional Manufacturing Employment: The Soap and Detergent Sub-Industry In Ontario, 1962-1984

Stevanovic, Vesna 04 1900 (has links)
<p> This thesis examines the influence of size and ownership of plants on the employment characteristics and locational behaviour of plants. The variables utilized to attain this objective were: foreign and Canadian-owned plants; single and multi-plants; plant, office and executive employment; location of plants within Toronto Census Metropolitan Area; and location of plants among aggregated areas in Ontario. Two methods were used in analysing the data. First, the mean of plant and employment data were obtained to provide employment characteristics. Second, regression analysis was performed to obtain in what areas there was a growth or decline of plants and employment. </p> <p> The result of the study show that foreign-owned plants employ a greater proportion of unskilled labour and are growing in reletively rural areas. On the other hand, single plants employ a greater proportion of executives and are growing within the outskirts of the Toronto Census Metropolitan Area. </p> / Thesis / Bachelor of Arts (BA)
