“…The treatment of wheat native starch with glycerol [32,33] and PEG400 at 80 • C allowed a pre-plasticization of starch before the compression moulding. Only during compression moulding the plasticization occurred but the pre-treatment at 80 • C was necessary to prepare the starch grains [26,30] to the subsequent brief step of 1 min at the higher temperature of 190 • C. Under compression moulding, both the EM powder and the P-PLST were molten and flowed under the applied pressure with plasticization conditions quite mild.…”

“…PHB is the polymer with the simplest structure in this group but copolymers with valerate or other repeating units can be considered belonging to the general family of PHAs. PHB shows properties comparable to petroleum-based polymers (e.g., polypropylene; PP), such as high melting temperature (175 • C) and relatively high tensile strength (30)(31)(32)(33)(34)(35). However, pure PHB has had only a limited use mainly because of its intrinsic brittleness (presenting low strain at break) and a narrow processing temperature range [16][17][18].…”

Preparation of Innovative Skin Compatible Films to Release Polysaccharides for Biobased Beauty Masks

The preparation and selection of biobased materials compatible with skin is essential for producing innovative and highly eco-friendly beauty masks. The use of a commercial elastomeric poly(hydroxyalkanoate) and starch was fundamental to select materials for bioplastic films with the necessary resistance in wet conditions, skin compatibility and capacity for a fast release of polysaccharides and similar active and functional molecules. Micrometric calcium carbonate was also used to control the stickiness of film during moulding. Starch release in water was investigated by gravimetric and infrared analyses. The compatibility with skin was investigated via two different in vitro tests based on human keratinocytes and human mesenchymal stromal cells. The materials were highly cytocompatible with skin, enabled immune modulation by keratinocytes and starch release in water up to 49% by weight in 30 min. These outcomes are a good starting point for boosting the production of biobased and biodegradable beauty masks, thus decreasing the impact onto environment of cosmetic products that are currently still mainly produced using petrol-based substrates.

“…The bands 2931 and 2888 cm À1 referred to the CH─O bond, the bands 1415, 1316, and 1210 cm À1 corresponded to the CH bonds, and bands 1117 and 1018 cm À1 were from the CO bond. [53][54][55] The spectrum of Glut is known in the literature and Patro et al 56 reported it in support information of their paper. The spectrum presented the more important bands around 2900 and 1715 cm À1 related to C─H stretching and C═O stretching (from the aldehyde group).…”

Chitosan (Cs) and polyaniline (PANI) were studied in this article for possible application as conductive and flexible films. Cs is a biodegradable polymer, that presents interesting properties as film applications. Otherwise, PANI is a semiconductor polymer with a wide range of applications. The films were produced by casting adding 30% glycerol and glutaraldehyde. The morphology, thermally, chemical structure, and electrical properties of films were obtained.Results showed the casting technique becomes possible to obtain self-standing films, with a chemical structure identical to precursor materials. Glutaraldehyde reacted to amine groups of terminal PANI chains, acting in the increase of electric conductivity and decrease of sheet resistance. The plasticizing effect of glycerol increased the spacing between Cs chains and facilitated the PANI dispersion. Therefore, glycerol and glutaraldehyde proved to be extremely efficient in increasing the electrical conductivity of blends.

“…This phenomenon indicates that nanoclay able to break the triple bond of the matrix to combine with nanoclay in the exfoliating mechanism. Peak around 2347 2360 cm −1 is attributed to CO2 content resulting from measuring conditions and does not represent the bioplastic decomposition to CO2 [23]. The peaks at the wavenumber range from 1435 to 1405 cm -1 indicated the C-H deformation and CH2-bending vibrations.…”

The highly synthetic plastic waste makes worrisome problems for the biosphere, so the use of bioplastic was applied for reducing this problem. Biocomposite based cassava starch-carrageenan blend with nanoclay reinforcement has great potential to increase their properties. The research objective was to evaluate the biocomposite properties in the presence of nanoclay added to starch/carrageenan blend matrix composite. The method was an experiment research using addition various nanoclay content as much as 2.5%, 5.0%, 7.5%, and 10.0% (wt/wt) into starch/carrageenan blend matrix. The procedures include a biocomposite synthesis using the casting methods and characterized of biocomposite properties using XRD, FTIR, SEM, and TGA. The mechanical strength was measured on a tensile strength tester. The results show that the nanoclay addition into starch/carrageenan matrix affects the structure, tensile strength, and thermal stability. This result shows that the addition of nanoclay into starch/carrageenan based matrix affects the mechanical properties, thermal stability through structural change. The variations of nanoclay content in biocomposite of 0
