Abstract

Disclosed is a fat-dissolving cleaner for hard surfaces, which has great foaming power and comprises an amine oxide surfactant, monoethanolamine and/or triethanolamine, a water-soluble organic solvent, water, and a cellulose-based polymer for increasing the adhesive stability of the foam. Said cleaner can be used in a spray bottle for cleaning hard surfaces and especially for removing burned or old grease stains in a method that encompasses the following steps: the cleaner is sprayed on, is let to react, and is wiped off with a moist cleaning cloth, sponge, or other common cleaning device once the foam has collapsed.

Description

"Foam Reinforced Cleaner"

The subject of this application is a grease-dissolving hard-surface cleaning agent which contains a cellulose-based polymer to improve foaming power.

Usual household cleaning products and, in particular, for the kitchen sector are characterized among others by a high fat dissolving power. This is caused, inter alia, by their high proportion of solvents, which, however, means that their foaming power is often low. Also with suitable nozzles, e.g. Trigger bottles, often no stable foam can be produced, which would be advantageous in particular for fat solution on vertical surfaces. A stable foam could take longer due to its adhesiveness and thus would result in less use of raw materials a better grease dissolving ability, even on stoved or aged dirt.

A fat-dissolving cleaning agent is described, for example, in EP 1 071 735 B1. It is a concentrate of water-insoluble organic solvent, amines and amine oxide-based nonionic surfactant. This concentrate should be used in dilute form; For a good foaming solution for cleaning vertical surfaces, lauryl amine oxide is the preferred surfactant. Even with this surfactant, however, the foaming power is unsatisfactory for many purposes.

A sprayable degreasing (oven) cleaning agent is described in US 5364551. The agent comprises an alkali metal hydroxide, an organic surfactant, an organic polymer as a thickener and water. A preferred embodiment comprises a mixture of an alkali metal hydroxide and an organic base from the group comprising mono-, di- and triethanolamine and mixtures thereof, a corrosion inhibitor, a xanthan thickener, a cationic amine oxide and an amphoteric surfactant. In this patent, the main focus was on the droplet size of the sprayed aerosol and the associated potential airway irritation associated therewith. The problem of lacking foam stability was not addressed.

The object that arises in the present application, therefore, is to provide a cleaner for hard surfaces, which in addition to high fat dissolving power also has a particularly large foaming power and thus longer adhering to vertical surfaces, resulting in an increase of the cleaning line. It has now been found that the foaming power of fat-dissolving cleaning agents which contains a combination of amine oxide-based surfactants, mono- or triethanolamine, another alcoholic or glycol ether-based solvent and other alkaline components, for example sodium or potassium hydroxide, already lower by addition Quantities of a cellulose-based polymer, such as hydroxyethyl cellulose, hydroxypropyl cellulose, etc., can be significantly increased. When using an identical trigger foam nozzle the cellulose polymer-containing cleaning agent adheres to vertical surfaces longer than a comparable cleaner without such a foam booster.

The subject of the present application is accordingly a grease-dissolving hard-surface cleaning composition which contains an amine oxide surfactant, monoethanolamine and / or triethanolamine, a water-soluble organic solvent and water, and additionally a cellulose-based polymer.

The advantage of such an agent is the very good grease dissolving power even on vertical surfaces and the increased cleaning performance due to the extended exposure time for the same amount of active agent. In addition, the cleaning effect is perceived by the consumer by collapsing and slipping off after the exposure time of the foam.

In the context of the present invention are fatty acids or fatty alcohols or their derivatives - unless otherwise stated - representative of branched or unbranched carboxylic acids or alcohols or their derivatives having preferably 6 to 22 carbon atoms. The former are particularly preferred for their vegetable base as based on renewable raw materials for environmental reasons, but without limiting the teaching of the invention to them. In particular, the oxo alcohols or their derivatives, which are obtainable, for example, by the RoELEN's oxo synthesis, can also be used correspondingly.

Whenever in the following alkaline earth metals are mentioned as counter ions for monovalent anions, this means that the alkaline earth metal, of course, only in the half - sufficient for charge balance - amount of substance as the anion is present.

Substances which also serve as ingredients of cosmetic products are hereinafter referred to as appropriate according to the International Nomenclature Cosmetic Ingredient (INCI) nomenclature. Chemical compounds carry an INCI name in English, plant ingredients are listed only after Linne in Latin.

The composition according to the invention is particularly suitable for spraying, producing a stable foam. A second subject of the invention is therefore a product of the detergent and a spray bottle. The spray dispenser is preferably a manually activated spray dispenser, in particular selected from the group comprising aerosol spray dispensers, pressure-building spray dispensers, pump spray dispensers and trigger spray dispensers, in particular pump spray dispensers and trigger spray dispensers with a transparent polyethylene or polyethylene terephthalate container.

In addition, the agent may also be filled into a corresponding aerosol spray bottle with the addition of a suitable propellant (e.g., n-butane or a propane / butane mixture). However, such a spray dispenser is less preferred.

The cleaning agent according to the invention is used for cleaning hard surfaces and in particular for removing stained or aged greasy dirt and is used in a corresponding cleaning process, which consists of the steps of spraying the grease-dissolving cleaning agent using the product of cleaning. and after the collapse of the foam, wipe it with a damp cloth, sponge or other usual cleaning equipment.

A exemplary embodiment

The inventive cleaner formulations E1 to E3 and the comparative formulation V1 were prepared. The latter contained no cellulose-based polymer. The formulations were filled into commercially available trigger bottles (type EGC, Henkel, snap-on PET) with a triggered trigger spray head (Afa-Polytec trigger, opAd, Combi sieve foam nozzle).

Foam adhesion stability was checked as follows:

With the help of the trigger gun, one spray of the detergent formulation was sprayed from a distance of 20 cm against a ceramic tile wall. The height position of the resulting foam after spraying on the tile wall H (t = O) in cm was noted. After one minute, the height position of the foam on the tiled wall H (t = 1 min) in cm was again noted. The relative foam stability SHS in% was determined from the ratio of the two height position values. In each case, the lowest position at which drop-type cleaning agent was located was evaluated.

SHS * 100 x (H (t = 1 min): H (t = 0 min))

The foam of the Comparative Cleaner V1 showed only 41% foaming stability, while the cleaners E1-E3 according to the invention had up to 58% foam stability.
