Abstract

The present invention relates to a of disinfecting and/or cleaning a hard-surface with a composition comprising a biguanide antimicrobial agent, an essential oil or an active thereof and an organic acid or a salt thereof whereby immediate and/or long lasting disinfecting benefits are provided.

Claims

1. A method of disinfecting and/or cleaning a hard-surface comprising the step of:

Contacting said surface with a composition comprising a biguanide antimicrobial agent, an essential oil or an active thereof and an organic acid or a salt thereof.

2. The method of claim 1, wherein said composition is a liquid composition having a pH from 4 to 14.

3. The method of claim 1, wherein said biguanide antimicrobial agent is an oligo- or poly-alkylene biguanide or a salt thereof or a mixture thereof.

4. The method of claim 3, wherein said biguanide antimicrobial agent is an oligo- or poly-hexamethylene biguanide or a salt thereof or a mixture thereof.

5. The method of claim 3, wherein said biguanide antimicrobial agent is poly (hexamethylene biguanide) hydrochloride.

6. The method of claim 1, wherein said biguanide antimicrobial agent is 1,1′

-hexamethylene-bis-[5-(p-chlorphenyl)-biguanide].

7. The method of claim 1, wherein said composition comprises up to 20% by weight of the total composition of said biguanide antimicrobial agent.

8. The method of claim 1, wherein said essential oil is selected from the group consisting of oils obtained from thyme, lemongrass, citrus, lemons, oranges, anise, clove, aniseed, cinnamon, geranium, roses, mint, lavender, citronella, eucalyptus, peppermint, camphor, sandalwood, pine, vervain, rosmarin, fleagrass, ratanhiae, cedar and mixtures thereof;

and

wherein said an active thereof is selected from the group consisting of actives of essential oils consisting of thymol, eugenol, menthol, geraniol, verbenone, eucalyptol, pinocarvone, cedrol, anethol, cinnamic acid, cinnamyl aldehyde, cinnamyl alcohol, carvacrol, hinokitiol, berberine, ferulic acid, methyl salicylic acid, methyl salicylate and terpineol and mixtures thereof.

9. The method of claim 1, wherein said composition comprises up to 20% by weight of the total composition of said essential oil or an active thereof.

10. The method of claim 1, wherein said organic acid is selected from the group consisting of mono- and poly-carboxylic acids, percarboxylic acids, substituted carboxylic acids, and mixtures thereof.

11. The method of claim 1, wherein said composition comprises up to 20% by weight of the total composition of said organic acid or a salt thereof.

12. The method of claim 1, wherein said composition further comprises an additional ingredient selected from the group consisting of solvents, surfactants, peroxygen bleaches, radical scavengers, chelating agents and mixtures thereof.

13. The method of claim 1, wherein said composition is incorporated onto a wet wipe.

14. The method of claim 1 wherein said composition provides immediate and long lasting disinfecting benefits to said surface.
