Water-in-oil emulsion compositions
Claimed is an emulsifier-free water-in-oil composition comprising: an amino-functional siloxane polymer; an ionic salt (<5 wt.%); and water, wherein the water is present in an amount of at least 50% by weight of the composition. Preferably, the composition is in the form of a cream. Preferably, the degree of substitution of nitrogen in the amino-functional siloxane polymer is in the range 0.4% to 2% nitrogen. Preferably, the water is present as at least 70 wt.% of the composition. Most preferably, the ionic salt is present at up to 2 wt.% of the composition. Preferably, the composition further comprises an amino-free siloxane polymer, most preferably polydimethylsixolane (PDMS, dimethicone). Preferably the amino-functional and amino-free siloxane polymers account for less than 10 wt.% of the composition. Preferably, the composition further comprises a silane and/or a hydrocarbon solvent. Composition may be used for the hydrophobic treatment of a building material (e.g. wood, timber, masonry, cement etc.).
