Abstract
Chemical processes to change the hair shape can lead to damaged hair fibre. Here, we propose benign formulations based on different types of cellulose using imidazolium ionic liquids (ILs) and a commercial serum as solvents. Formulations with concentrations at 3% and 0.5% of HEC (Hydroxyethyl cellulose) and CMC (Carboxymethylcellulose) showed the best results after washing, around 10% of curling effect. Images from fluorescence microscopy enable to observe the coating layer formed on the surface of the hair fiber. ATR-FTIR corroborate the presence of functional groups of cellulose on the coated hair fiber. SEM images revealed that the treated hair fiber preserved it structural integrity, especially for the 3% CMC formulation. Those formulations also presented good mechanical wear determined by mass loss percentage. The novelty of this work is the methodology established associated with the cellulose formulation for hair modelling up to three washes.
期刊介绍:
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
