Claims14
A softener concentrate to be emulsified with water to form an oil-in-water softener emulsion for use in manufacture of a paper, tissue or paperboard, comprising:
- 5 to 10 wt % of an imidazoline-based surfactant with a carbon chain of 16 to 18 carbon atoms based on the total weight of the softener concentrate;
- 5 to 10 wt % of a lanolin-based softener based on the total weight of the softener concentrate;
- 5 to 20 wt % of phospholipids based on the total weight of the softener concentrate;
- and
- 60 to 85 wt % of a surfactant blend based on the total weight of the softener concentrate comprising polysorbate ester, sorbitan ester-based surfactants, polypropylene glycol, polyethylene glycol, and their esters, silicon-based softeners, or any combination thereof.
