Claims18
A dry composition for chemical and physical sun protection, the dry composition comprising
- a) at least one mineral material selected from the group consisting of surface reacted calcium carbonate and hydromagnesite,
- wherein the surface-reacted calcium carbonate is a reaction product of natural ground calcium carbonate or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source and
- b) from 0.1 wt.-% to 100 wt.-% of at least one lignin, based on the dry weight of the at least one mineral material, and
- wherein the at least one lignin is in the form of a coating on the at least one mineral material.
