Adsorption of Fragrance Capsules onto Cellulose Nano- and Micro-Cellulose Fibers in Presence of Guar Biopolymers

Round 1

Reviewer 1 Report

This article describes the importance and type of the interactions responsible for better adsorption of fabric softeners on textiles. The research suggests the use of a formulation for fabric softeners that is environmentally friendly, achieves improved fragrance delivery, improves the fabric softening properties of household products and contributes to sustainability and product performance. The article is excellently written and presented. The results achieved are explained in an understandable and detailed manner. Only a few word errors were found during the review, such as:

-Table 2: letter s is missing in CNCs

- letter d is redundant in the word dbehavior (page 7)

- letter i is missing in the word addtion (page 9)

After these corrections, the article is suitable for publication.

Author Response

We would like to express our gratitude to the reviewer for taking the time to read our manuscript and for his/her comments. We have incorporated the reviewer's suggestions into the revised version, particularly with regard to the changes to be made on Table 2, and on pages 7 and 9.

Reviewer 2 Report

The paper is well written. The trials taken are  quite sensible,  the tests carried out are absolutely pertinent and explanations given are very much appreciated. 

The quality of English is reasonably good.

Author Response

We thank the reviewer for his/her comments on our manuscript. As no modifications were requested, we have not changed the original text.

 

Reviewer 3 Report

More information about the obtention of SEM images. The representativity os sampling should be clarified.

Author Response

We would like to thank the reviewer for taking the time to read our manuscript and for his/her comments on the points under discussion, particularly concerning the SEM data.

 

The manuscript has been refined in the light of the reviewer's valuable comments. A paragraph has been added concerning the SEM images and the aspect on the representativeness of SEM images is now clarified. For the SEM experiments, we collected several hundred images at various magnifications between X100 and X40000, and the SEM images presented in the manuscript are the result of a careful selection from these data.

Reviewer 4 Report

This manuscript investigates the adsorption of anionic fragrance capsules on cotton fabrics with the goal of reducing the reliance on palm-oil-derived surfactants. This research demonstrates that anionic fragrance capsules are deposited onto cotton microfibers in the presence of either cationic surfactants or guar biopolymers, driven by electrostatic interactions. The data in this work can support the conclusion, and this manuscript can meet the scope of the journal of “Coatings”. However, there are still some problems in this manuscript. It needs a minor revision before becomes acceptable for publication in this journal.

1. Page 9, “It should be noted that for Figs. 3a, 3b and 3c, the experimental conditions were the same in terms of concentration, pH and temperature, and from their comparison it can be concluded that TEQ and CAPS exhibit the strongest interaction strength”, TEQ and CAPS exhibit the strongest interaction strength, what is the reason?

2. Some sentences in the manuscript are poorly written. For example:

Page 6, “It is worth noting that CNCs, being colloids with differing translational diffusion constants parallel and perpendicular to their main axis, do not directly relate to the particle length or the conventional hydrodynamic diameter.”

Page 9, “we then study mixed of TEQ/CAPS dispersion with cellulose nanocrystals.”

We thank the reviewer for taking the time to read the manuscript and for commenting on contentious points. The manuscript has been modified based on the reviewer's comments.

 

Concerning the concept of interaction strength, we have shown in a previous article that for colloidal species of opposite charge, mixtures gave rise to a light scattering peak, the intensity of which being proportional to the interaction strength. This technique is widely used in bulk dispersions to determine whether species interact with each other, usually forming aggregates. See for example : Mousseau, F.; Berret, J.-F. The Role of Surface Charge in the Interaction of Nanoparticles with Model Pulmonary Surfactants. Soft Matter 2018, 14, 5764-5774, doi:10.1039/c8sm00925b.

 

The two sentences highlighted for their formulation have been modified. The second was indeed a typographical error, which has now been corrected.
