Abstract: An electrode array device for use with a conductive element to simulate a crevice that is subject to corrosive conditions. The device includes a non-conductive member and a plurality of electrodes. The non-conductive member has a face, with the member defining (i) an opening through the member, the opening passing through the face of the member, and (ii) a depression formed in the face and contiguous with at least a portion of the opening. The plurality of electrodes is embedded in the member, with each of the plurality of electrodes having a portion exposed from the member to the depression.

Abstract: Asymmetrical diesters of orthophosphoric acid are added to corrosive hair conditioning compositions to inhibit corrosion of metal coming into contact with the composition. The hair conditioning properties of the hair conditioning compositions are not adversely affected.

Abstract: A corrosion inhibitor system and method for inhibiting corrosion in aqueous compositions within aerosol containers. The composition comprises at least one Group I metal salt of benzoic acid and at least one phytate selected from the group consisting of Group I and Group II metal salts of phytic acid and mixtures thereof, when the ratio of benzoate to phytate is about 10:1 to 1:10 and preferably 2.5:1, the corrosion inhibitor system being present in an amount of about 0.1 to 4% by weight of the composition. The method comprises adding an effective amount of at least one Group I metal salt of benzoic acid and at least one phytate selected from the group consisting of Group I and Group II metal salts of phytic acid and mixtures thereof to reduce corrosion in steel aerosol containers containing corrosive aqueous compositions. The ratios of benzoate to phytate are effective to inhibit corrosion in the aqueous system.
