Sanitizing formulation
A sanitizing formulation comprising a solution of an acidic polymer and an anionic surfactant in a liquid vehicle. Suitable acidic polymers are those which include adjacent —[—CR 1 .COOH—]— units where R 1 is defined in their structure, for example polymers based on maleic acid moieties which typically include —[—CH.COOH—CH.COOH—]— units, such as known Gantrez™ polymers. A suitable anionic surfact is sodium lauryl sulphate.
1. An alcohol-free sanitizing formulation having anti-viral activity comprising a solution of 1-5 wt % of an acidic polymer comprising a homopolymer of acrylic acid crosslinked with an allyl ether, 1-5 wt % of an anionic surfactant, and 0.5-7 wt % of citric acid made up to 100% with water, at pH 2-4, wherein the acidic polymer and anionic surfactant interact to form a viscous gel.
2. The sanitizing formulation according to claim 1 wherein the acidic polymer comprises a homopolymer of acrylic acid crosslinked with an allyl ether of pentaerythritol, of sucrose or of propylene.
3. The sanitizing formulation according to claim 2 wherein the acidic polymer comprises Carbopol ETD 2020.
4. The sanitizing formulation according to claim 1 wherein the anionic surfactant is a compound having a hydrophilic anionic group and an associated cation.
5. The sanitizing formulation according to claim 4 wherein the anionic surfactant is selected from sodium lauryl sulphate, sodium laureth sulphate, and alpha-olefin sulphates.
6. The sanitizing formulation according to claim 5 comprising Carbopol™ ETD 2020 and sodium lauryl sulphate or an alpha-olefin sulphate.
7. The sanitizing formulation according to claim 1 wherein the acidic polymer and the anionic surfactant are present together in the solution in the ratio of weight % acidic polymer:anionic surfactant 1-2:2-1.
8. The sanitizing formulation according to claim 1 provided for use as a sanitizing formulation for a surface.
9. A concentrate suitable for dilution with a liquid vehicle to thereby provide a sanitizing formulation as claimed in claim 1 .
10. A sanitising formulation according to claim 1 having anti-viral activity consisting of a solution of 1-5 wt % of an acidic polymer comprising a homopolymer of acrylic acid crosslinked with an allyl ether, 1-5 wt % of an anionic surfactant, and 0.5-7 wt % of citric acid made up to 100% with water, at pH 2-4, wherein the acidic polymer and the anionic surfactant interact to form a viscous gel.
