The disclosure relates to hard surface cleaning compositions, methods of making the hard surface cleaning compositions, and methods of using the hard surface cleaning compositions. In particular, the hard surface cleaning compositions have reduced surface tension for cleaning surfaces with low surface free energy. Preferably, the hard surface cleaning compositions have low contact angles on a variety of surfaces.

Composition comprising mixtures of glucam ides, process for their preparation and their use

Disclosed are compositions comprising a) 20 to 84% by weight of specific N-hydrocarbon-N-acylglucamide blend, b) 15 to 50% by weight of water, and c) 1 to 30% by weight of one or more other additives.

The compositions may be present, at a temperature of 20 C., in the form of a gel or in the form of a paste, and furthermore e.g. in the form of a monodose product.

The compositions are suitable for cleaning, scenting, conditioning or disinfection purposes, preferably in home or personal care applications.

According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.

Liquid detergent compositions can be stably structured using amides of an aliphatic polyamine with two, three or four molecules of fully saturated hydroxyl alkyl acids, even in the presence of hydrolysing detergent ingredients such as lipase enzyme.

Methods and related systems include applying a first fluid to a hard surface, grinding the hard surface using at least one structured-abrasive pad while removing the first fluid, applying a second fluid to the hard surface, and scrubbing the hard surface using a floor bristle brush while removing the second fluid. Some surface enhancement compositions include a first nonionic surfactant including alcohol alkoxylate, a second nonionic surfactant including a different alcohol alkoxylate, and a third nonionic surfactant having an amide functional group. Other compositions include a nonionic surfactant having alcohol alkoxylate, a polymer, and a siloxane.

Silicone hydrogel contact lenses are packaged in a packaging solution including an ophthalmically-acceptable concentration of a surfactant to provide a contact lens having a lower coefficient of friction compared to a control lens that is not packaged in the surfactant. The surfactant is a poly(ethylene oxide) (PEO)-containing surfactant having a molecular weight of up to about 6,000 daltons, or is an alkyl aryl-containing surfactant, or is both an alkyl aryl and PEO-containing surfactant having a molecular weight of up to about 6,000 daltons. Methods of manufacturing silicone hydrogel contact lenses are also described.

The invention relates to an emulsion containing or consisting of (A) 40.00 to 97.98 wt. % of at least one hydrocarbon, (B) 2.00 to 59.98 wt. % of water or an aqueous solution of a salt which does not fall under the following definition according to (C) and (C) 0.02 to 8.00 wt. % of a salt of an amino amide of a fatty acid, containing at least one primary, secondary or tertiary amino group, and an acid component of general formula (I)

##STR00001## in which R.sup.1 is a linear or branched, saturated or mono-unsaturated or poly-unsaturated hydrocarbon radical with 1 to 40 C atoms, R.sup.2 is an alkylene radical or arylalkylene radical with 2 to 20 C atoms and X is a radical which contains at least one acid group, m=0 or 1, n=1 to 30, wherein the weight proportions of components (A), (B) and (C) relate to the sum of the masses of these components and this is 100 wt. %. The invention also relates to a method for the production of the emulsion, to an oil-based drilling mud and to a method for creating and stabilizing a drill hole.

According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.

Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C.sub.10-C.sub.17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.

Liquid detergent compositions can be stably structured using amides of an aliphatic polyamine with two, three or four molecules of fully saturated hydroxyl alkyl acids, even in the presence of hydrolyzing detergent ingredients such as lipase enzyme.
