Man has always given much importance to the hair, not only because of the physiological properties that distinguish it, but also and above all because of its aesthetic profile, so much that a little thick and damaged hair can cause psychological stress.

The packaging has been chosen in such a way as to guarantee the delivery of a certain amount of beads. Once the most suitable packaging has been identified, the evaluation of the stability of the product over time has been carried out. Specifically, various parameters were analysed, such as: organoleptic characteristics, pH evaluation of the suspension and morphological and dimensional properties of the beads. All this was evaluated over a period of three months at a temperature of 20°C.

L’uomo ha da sempre attribuito molta importanza al capello, non solo per le proprietà fisiologiche che lo contraddistinguono ma anche e soprattutto per il suo profilo estetico, tanto che una chioma poco folta e rovinata può essere causa di stress psicologico. Il settore cosmetico infatti è sempre alla ricerca di prodotti innovati per capelli, che siano in grado di conferire ad essi protezione, riparazione, lucentezza e morbidezza, alcune delle caratteristiche maggiormente richieste dal consumatore. Pertanto l’obiettivo del presente elaborato di tesi è stato lo sviluppo di una formulazione spray per capelli, che fosse in grado di ripararli dai danni provocati dagli agenti atmosferici, quali raggi UV, dallo smog e dall’uso scorretto di fonti di calore eccessive, quali phon e piastra. In particolare è stata realizzata una sospensione di sistemi particellari, denominati beads, ottenuti mediante il processo di coacervazione. Allo stesso tempo sono state valutate diverse tipologie di packaging al fine di individuare il più idoneo al conseguimento dell’obiettivo preposto. Il packaging è stato scelto in modo tale da garantire l’erogazione di una determinata quantità di beads. Una volta individuato il packaging più adatto, è stata effettuata la valutazione della stabilità del prodotto nel tempo. Nello specifico sono stati analizzati diversi parametri, quali: le caratteristiche organolettiche, la valutazione del pH della sospensione e le proprietà morfologiche e dimensionali delle beads. Il tutto è stato valutato in un periodo di tempo pari a 3 mesi, a una temperatura di 20°C. Per quanto riguarda invece l’ultima fase del presente progetto è stata valutata l’effettiva performance del prodotto, valutandone anche l’efficacia. Quest’ultima è stata analizzata mediante lo svolgimento di test ex vivo su ciocche denaturate per poter provare che i claim vantati fossero rispettati. In conclusione è stato possibile realizzare un prodotto cosmetico spray, a base di sistemi particellari, da poter applicare sui capelli al fine di migliorarne le proprietà strutturali.

Abstract
Man has always given much importance to the hair, not only because of the physiological properties that distinguish it, but also and above all because of its aesthetic profile, so much that a little thick and damaged hair can cause psychological stress. The cosmetics sector is always looking for innovative hair products, which are able to give them protection, repair, shine and softness, some of the characteristics most requested by the consumer. Therefore the objective of this thesis paper was the development of a hair spray formulation, which would be able to repair them from the damage caused by weather conditions, such as UV rays, from smog and misuse of excessive heat sources, such as hairdryer and plate. In particular, a suspension of particle systems, called beads, obtained by the coaching process was realized. At the same time, different types of packaging have been evaluated in order to identify the most suitable to meet the target. The packaging has been chosen in such a way as to guarantee the delivery of a certain amount of beads. Once the most suitable packaging has been identified, the evaluation of the stability of the product over time has been carried out. Specifically, various parameters were analysed, such as: organoleptic characteristics, pH evaluation of the suspension and morphological and dimensional properties of the beads. All this was evaluated over a period of three months at a temperature of 20°C. As for the last phase of this project, the actual performance of the product has been evaluated, also evaluating its effectiveness. The latter has been analysed by carrying out ex vivo tests on denatured strands in order to prove that the claims were respected. In conclusion it was possible to create a cosmetic spray product, based on particle systems, to be applied on the hair in order to improve its structural properties.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
