Abstract: A synergistic composition and a synergistic system for use in treating the skin and hair of people and animals comprises separate treatment compositions (solution, dispersions, emulsions, suspensions or other liquid or liquefiable materials). One treatment with a first composition that may comprise at least 0.1% by weight of antimicrobially active aliphatic phenol derivative and treatment with another composition being selected from the group consisting of:a) a solution comprising an antimicrobially active cationic species;b) a comprising antimicrobially active aliphatic phenol derivative, preferably in a different weight percentage of antimicrobially active aliphatic phenol derivative than said one composition, comprising greater than 0.3% antimicrobially active aliphatic phenol derivative;c) a solution comprising an alcohol provides a synergistic antimicrobial action.

Abstract: A time delay relay circuit of the present invention includes a power supply terminal, a relay having a first terminal connected to the power supply terminal, and a timing circuit, for activating the relay for a preset duration, having a supply input for receiving power for the timing circuit. Also included is a means for connecting the supply input of the timing circuit to the power supply terminal during operation of the timing circuit and activation of the relay and disconnecting the supply input of the timing circuit from the power supply terminal during non-operation of the timing circuit. The means connecting the supply input to the power supply terminal may be a switch which is closed and opened to start the preset duration time running within the timing circuit. During the preset duration, the switch remains open. The relay is closed making a connection between the power supply terminal and the supply input.
