Desarrollo de una gama de pintalabios y su proceso de fabricación

Abstract

Treballs Finals de Grau d'Enginyeria Química, Facultat de Química, Universitat de Barcelona, Curs: 2019-2020, Tutora: Alicia Maestro GarrigaThe development of a formulated product is based on the needs of the consumers that have been found by a search and in a transformation of these into a commercial product. This work has been done to develop three cosmetics products, a lip balm with sun protection, a solid lipstick and a fluid lipstick, these last two with colour pigment. These kinds of cosmetics have been and are nowadays very important to people. The three products are destinated as decorative for skin lips, because of that to have a well-looking appearance people used them. The sun protection lip balm consists on moisturize lips and at the same time protect them again UVA and UVB radiation from the sun and from extreme cold weather, which also can burn the skin. The other two products, the solid and fluid lipstick have functions as creamy, long lasting wearing and obviously they colour lips with red pigment. The big difference between the last two, is that they have different consistencies, but all of them are suspensions. It has been proposed three formulations with its required quantity of each ingredient and to make easier the manufacturing process they have many ingredients in common. To ensure that the three products will be a successful some quality factors must be achieved. These factors have been proposed based on the search made about the needs of consumers. As the three cosmetics have differences between them these factors will be different on some points and the same in others, like all of them must be creamy but the effectiveness of the sun protection will be done only on the lip balm. The manufacturing process has been carried out with a production by batches of 400 kg of the lip balm with sun protection and of the solid lipstick while the fluid lipstick will be done by batches of 800 kg. Three batches of each product will be finished at the end of each month. Moreover, to make this process, different flowsheets have been proposed and equipment units have been selected for each product, explaining each operation that will be done. Furthermore, some of these equipment units can do different operations because they are machine lines with different zones of working processe
