Abstract: A cleansing sheet including a nonwoven sheet impregnated with a cleaning agent, the cleaning agent containing 99.80 wt % to less than 99.95 wt % of purified water and more than 0.05 wt % to 0.20 wt % of a bactericidal preservative, the bactericidal preservative including more than 0.025 wt % to 0.10 wt % benzalkonium chloride, more than 0.0025 wt % to 0.01 wt % iodopropynyl butylcarbamate, and more than 0.0225 wt % to 0.09 wt % glycol, based on the total weight of the cleaning agent taken as 100 wt %. The cleaning sheet can be applied to the delicate skin of infants or the sensitive skin of elderly people.

Abstract: A gas burner of a low noise, high load combustion type, which produces a flame of a mixture gas prepared or mixed preliminarily. In this burner, an inner flame of a laminar flow is formed and then secondary air of a turbulent flow is supplied to an outer flame portion of a trailing stream of the inner flame from secondary air ports. The inner flame is provided in the form of a laminar flame, and secondary air is thus supplied to an outer flame portion of the inner flame, so that combustion takes place at a low noise level. In addition, since the secondary air is supplied at a turbulent flow, the secondary air may be fixed with an outer flame quickly, thus enabling high load burning or combustion. Furthermore, in case secondary air is supplied from secondary air ports in the form of a laminar flow at a relatively high flow velocity, and then rendered turbulent, downstream of the secondary air ports, then the size of a burner may be reduced, with an accompanying simplified construction.
