Abstract

Germicidally effective, d-limonene-containing aqueous pump-spray compositions are rendered clear and stable by monoethers of certain aliphatic glycols which also enhance soil and stain removal from hard surfaces. The compositions also contain quaternary ammonium compounds, non-ionic surfactants, alkali builders and may contain lower aliphatic alcohols.

Claims

1. A clear, stable aqueous cleanser composition comprising about 0.45 to 0.7 percent of a germicidally effective quaternary ammonium compound;

about 0.4 to 1 percent d-limonene;

about 1 to 1.5 percent of a non-ionic surfactant selected from an ethoxylated linear (C₁₂ -C₁₅) alcohol and an ethoxylated alkyl phenol, containing about 7 to 12 moles of condensed ethylene oxide;

about 1 percent of an alkali builder and about 4 to 6 percent of a monoether of an aliphatic glycol containing about 59 to 65 percent, by weight, carbon.

2. The composition of claim 1 wherein the quaternary ammonium compound is selected from the group consisting of alkyl dimethyl benzyl and alkyl dimethyl ethylbenzyl ammonium compounds wherein the alkyl group contains about 12 to 18 carbon atoms and dialkyl dimethyl ammonium compounds wherein each alkyl group contains about 8 to 10 carbon atoms.

3. A composition of claim 1 or claim 2 comprising about 0.45 to 0.7 percent of a mixture comprising about 50% C₁₄ -C₁₈ alkyl dimethyl benzyl ammonium chloride and about 50% C₁₂ -C₁₈ alkyl dimethyl ethyl benzyl ammonium chloride about 0.4 to 1 percent d-limonene;

about 1 to 1.5 percent of an ethoxylated linear C₁₂ -C₁₅ alcohol containing about 9 moles of condensed ethylene oxide;

about 1 percent of an alkali builder selected from potassium carbonate and sodium metasilicate; and

about 4 to 6 percent of a monoether of an aliphatic glycol selected from 1-butoxyethoxy-2-propanol, monobutyl ether of ethylene glycol and monobutyl ether of diethylene glycol.

4. The composition of claim 1, or claim 2 further comprising up to about 7 percent of a lower aliphatic alcohol.

5. The composition of claim 4 wherein the lower aliphatic alcohol is selected from ethanol and isopropanol.
