Important results from the project

The purpose of this project was to examine the potential of cellulose nanofibrils containing lignin (LCNF) as a natural multi-functional ingredient in cosmetic formulations. Both commercial unbleached softwood pulp from Sweden and agricultural residue from the exploitation of fruits from the Amazon region in Brazil were used. Processed materials were formulated as a cream and evaluated in terms of viscosity modifying properties, stability, moisture preservation and functional bioactivity (antioxidant and anti-UV properties) as well as the perception experience upon use.

Expected long term effects

The nanocellulose materials with (LCNF) and without (CNF) lignin acted as a natural thickener in the cream formulations. Pleasant, easy spreadable creams with no sticky after feel could be made but with a tendency to feel particulate matter, especially with the creams containing lignin. A trend in increased skin hydration was also noted. Carboxymethylated pretreatment of the pulp yielded CNF with the highest stability at the same level of commercial creams at the conditions tested. At the concentration used in the formulations no functional bioactivity was measured.

Approach and implementation

The project consisted of five work packages with defined deliverables: management (WP1), production of pulp from Brazilian residual biomass (WP2), production and characterisation of LCNF/CNF materials (WP3), formulation and characterisation of cosmetic formulations (WP4) and market strategies (WP5). LCNF/CNF materials from residual biomass were shipped to Sweden to be formulated and cream formulations were shipped to Brazil for some characterisation and evaluation. More time should have been allotted to account for issues and delays in shipping.
