Nanocelluloses as skin biocompatible materials for skincare, cosmetics, and healthcare: Formulations, regulations, and emerging applications

“…With their small particle size, low aspect ratio along with their strong swelling properties, the NCSPs are not suitable as abrasive peeling or scrubbing media (Bouillon et al, 1998). However, they can be used for advanced skin treatment and healing (Uddin et al, 2019). Some specific features and attributes of NCSPs for utilization in skincare and cosmetic applications are below.…”

Sustainable smart anti-corrosion coating materials derived from vegetable oil derivatives: a review

“…renewable substances like cellulose, starch, sugar, etc. [4][5][6] Vegetable oils are the centre of attention owing to their favourable chemical structure, availability, cost, and unsaturated sites for functional group fabrication, thus advantageous for designing the molecules from scratch. 78 A variety of vegetable oils, e.g.…”

“… 1–3 The major challenge in today's emerging world is the replacement of conventional petroleum-based polymers with renewable polymers, where vegetable oils (VOs) are potential starting materials among other bio-based renewable substances like cellulose, starch, sugar, etc. 4–6 Vegetable oils are the centre of attention owing to their favourable chemical structure, availability, cost, and unsaturated sites for functional group fabrication, thus advantageous for designing the molecules from scratch. 78 A variety of vegetable oils, e.g.…”

Sustainable Cellulose Nanofiber Films from Carrot Pomace as Sprayable Coatings for Food Packaging Applications

“…CNFs are made by mechanically (and optionally enzymatically/chemically) fibrillating bulk cellulose fibers from a variety of lignocellulosic starting materials, , yielding long, flexible nanofilaments (length >1 μm, diameter ∼4–100 nm), having both crystalline and amorphous domains . Due to a combination of high surface area, good film-formability, good mechanical and optical properties, potential for chemical modification, and low oxygen permeability (high barrier properties), − CNFs have been reported as suitable raw materials for the formulation of films and coatings, as they offer several benefits and key features for effective performance in this field. − In this context, Fukuzumi et al produced TEMPO-oxidized CNF films from softwood cellulose which were transparent (90% transmittance at 600 nm) and durable (Young’s modulus 6.9 ± 1.4 GPa, tensile strength 233 ± 44 MPa) and demonstrated a high oxygen barrier (1 mL m –2 day –1 Pa –1 ) when cast on PLA films .…”
