Adsorption of a fabric conditioner on cellulose nanocrystals: Synergistic effects of surfactant vesicles and polysaccharides on softness properties [PDF]
Cellulose 28 (4) 2551-2566 (2021), 2020 Concentrated fabric conditioners are water-based formulations containing 10 wt. % of cationic surfactants that are deposited on textile fibers during the rinse cycle in a washing machine to make them smoother and softer to touch. In topical formulations, the concentration of cationic surfactants is reduced by half, this reduction being compensated by ...

CELLULOSE NANOCRYSTALS FROM BACTERIAL CELLULOSE [PDF]
Química Nova, 2015 Bacterial cellulose produced from Gluconacetobacter xilinus was used to produce cellulose nanocrystals by sulfuric acid hydrolysis. Hydrolysis was performed with 64% sulfuric acid at 50 oC with the hydrolysis time ranging between 5 and 90 min. The production of nanocrystals was observed to have size distributions that were dependent on hydrolysis times

Printing Flowers? Custom-tailored Photonic Cellulose Films with Engineered Surface Topography [PDF]
Matter, vol. 1, pages 988-1000 (2019), 2019 Wrought by nature's wondrous hand, surface topographies are discovered on all length scales in living creatures and serve a variety of functions. Inspired by floral striations, here we developed a scalable means of fabricating custom-tailored photonic cellulose films that contained both cholesteric organization and microscopic wrinkly surface ...

Critical Review on Sustainable Homogeneous Cellulose Modification: Why Renewability Is Not Enough [PDF]
ACS Sustainable Chemistry & Engineering, American Chemical
Society, 2018, 7 (2), pp.1826-1840, 2019 As we passed the 20th anniversary of the publication of the 12 principles of green chemistry, the sustainable modification of cellulose, being the most abundant biobased polymer, is certainly worth considering. Many researchers work on an efficient valorization of this renewable resource due to its manifold and promising application possibilities, but ...

Sustainable and effective antimicrobial surface based on cellulose thin films [PDF]
, 2022 In the present work, we developed a sustainable and effective antimicrobial surface film based on Micro-Fibrillated Cellulose. The resulting porous cellulose thin film is barely noticeable to human eyes due to its sub-micron thickness, of which the coverage, porosity and microstructure can be modulated by the formulations developed.

Model surfaces for paper fibers prepared from carboxymethyl cellulose and polycations [PDF]
arXiv, 2021 For a tailored functionalization of cellulose based papers, the interaction between paper fibers and functional additives have to be understood. Planar cellulose surfaces present a suitable model system for studying the binding of additives. In this work, polyelectrolyte multilayers (PEMs) as model surfaces are prepared by alternating dip coating of ...

Fabric Softener/Cellulose Nanocrystal Interaction: A Model For Assessing Surfactant Deposition On Cotton [PDF]
J. Phys. Chem. B, 121, 2299 - 2307 (2017), 2017 There is currently a renewed interest for improving household and personal care formulations to provide more environment friendly products. Fabric conditioners used as softeners have to fulfill a number of stability and biodegradability requirements. They should also display significant adsorption on cotton in the conditions of use.
