Abstract
The present invention provides formulations comprising a suspension of nanocellulose (NC) elements and a drying/dispersal additive selected from the group consisting of temperature-responsive polymers, small molecule additives in volatile systems, and blocking agents and methods of preparing such formulations, and further provides NC-containing materials, composite materials and useful articles of manufacture made therefrom.
Claims30
A method of producing an article of manufacture comprising a redispersible, dried nanocellulose (NC)-containing matrix with nanocellulose elements (NCEs) embedded therein and an active agent, wherein the active agent is selected from the group consisting of soaps, hair hold products, emollients, and cosmetics, and wherein the active agent is supported by, embedded in, attached to, or otherwise associated with the NC-containing matrix;
- the method comprising:
- drying a liquid formulation to form the redispersible, dried NC-containing matrix, wherein the liquid formulation comprises a suspension of the nanocellulose elements (NCEs) in a liquid medium and a drying/dispersal additive,
- wherein the drying/dispersal additive is selected from the group consisting of a temperature-responsive polymer, a small molecule additive in a volatile system, and a blocking agent;
- wherein the drying/dispersal additive disrupts hydrogen bonding between the NCEs during the drying;
- and
- wherein the redispersibility of the dried NC-containing matrix is greater than that of a dried control matrix prepared by drying a control suspension of the nanocellulose elements in the liquid medium, wherein the control suspension lacks the drying/dispersal additive.
A method of producing an article of manufacture comprising a redispersible, dried nanocellulose (NC)-containing matrix with nanocellulose elements (NCEs) embedded therein and an active agent, wherein the active agent is selected from the group consisting of a shampoo, a hair conditioner, a hair hold product, and a hair color preparation and wherein the NC-matrix is optically transparent;
- the method comprising:
- drying a liquid formulation to form the redispersible, dried NC-containing matrix, wherein the liquid formulation comprises a suspension of the nanocellulose elements (NCEs) in a liquid medium and a drying/dispersal additive,
- wherein the drying/dispersal additive is selected from the group consisting of a temperature-responsive polymer, a small molecule additive in a volatile system, and a blocking agent;
- wherein the drying/dispersal additive disrupts hydrogen bonding between the nanocellulose elements during the drying;
- and
- wherein the redispersibility of the dried NC-containing matrix is greater than that of a dried control matrix prepared by drying a control suspension of the nanocellulose elements in the liquid medium, wherein the control suspension lacks the drying/dispersal additive.
