Abstract:
The present invention provides hardwood derivatives of native lignin having an aliphatic hydroxyl content of from about 5.2 mmol/g to about 7 mmol/g. Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having a certain aliphatic hydroxyl content.
Abstract:
The present invention provides softwood derivatives of native lignin having an aliphatic hydroxyl content of from about 2.5 mmol/g to about 7 mmol/g. Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having a certain aliphatic hydroxyl content.
Abstract:
The present invention provides annual fibre lignin derivatives having an aliphatic hydroxyl content of from about 1 mmol/g to about 3.75 mmol/g Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having a certain aliphatic hydroxyl content
Abstract:
The present invention provides derivatives of native lignin having an aliphatic hydroxyl content of 2.35 mmol/g or less Suprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for deriatives of native lignin having a certain aliphatic hydroxyl content.
