The invention is a detergent solution for cleaning a receptacle for milk or liquid milk-derived products, the detergent solution comprising water, one or more types of surfactant and an odour absorbing compound. The surfactants are provided to dissolve greasy milk-based residues from the receptacle and the odour absorbing compound is provided to neutralise odours produced by any remaining milk-based residues not removed by the surfactants. The detergent solution is water-based so that it can be rinsed off easily in a sink in the home. The detergent solution is particularly suited to plastic receptacles because plastic is more prone to accumulating mal-odour producing bacteria. This is because a plastic surface is more porous than glass so it is more difficult to remove greasy residues from a plastic surface and therefore grease can build up in the pores, out of the reach of surfactants, and provide a place for odour-producing bacteria to grow. An odour absorbing compound does not remove the residue but can neutralise the odours from the residue. The invention also discloses a method for dispensing a detergent solution comprising at least one surfactant, the method comprising ejecting detergent solution from a reservoir in the form of a spray, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution. The invention discloses also a method of cleaning a receptacle for milk, or liquid milk-derived products, the method comprising: spraying a detergent solution comprising at least one surfactant onto the receptacle, wherein the surfactant is present in the detergent solution in an amount of from 3% to 15% by weight of the detergent solution.

A stable and safe skin antiseptic solution comprises chlorhexidine, pharmaceutically acceptable salts of chlorhexidine (e.g. chlorhexidine digluconate), or a mixture thereof, dimethyl lauramide/myristamide, and water. Said solution is essentially free of coconut oil diethanolamine concentrate (“cocamide DEA”), a known carcinogen. The active antiseptic ingredient, chlorhexidine (or its salts), is a di(4-chlorophenyldiguanido) compound. The functions of dimethyl lauramide/myristamide in said solution include, but not limited to, an aesthetics enhancer, a foam stabilizer, a solubilizer, and a fragrance. Said solution is specifically formulated to be safe with a reduced risk of carcinogenicity, and be capable of producing a stable and long lasting foam. The active antiseptic agent is evenly distributed in said solution and in said foam, respectively.

Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.
