Abstract

Aqueous cleaning agents for hard surfaces that dry more quickly after application, containing a surfactant and diquaternary polysiloxane, whereby the anionic surfactant content in relation to the total amount of surfactant and diquaternary poly(dimethylsiloxane) is at least 1 wt. %. Diquaternary polysiloxanes are suitable for use in a liquid cleaning agent for hard surfaces in order to reduce the drying time of the surface treated with said cleaning agent. According to a method for reducing the drying time of a hard surface treated with a liquid cleaning agent, said cleaning agent contains diquaternary polysiloxane.

Description

"Ali purpose cleaner with diquaternary polysiloxane"

The invention relates to aqueous liquid surfactant-containing cleaning agents for hard surfaces with diquaternary polysiloxane.

Universally usable cleaning agents for all hard, wet or damp wipeable surfaces in the household and business are known as so-called all-purpose cleaners and are predominantly neutral to weakly alkaline aqueous liquid products, the 1 to 30 wt .-% surfactants, 0 to 5 wt .-% builder (for example citrates, gluconates, soda. polycarboxylates) 0 to 10% by weight of hydrotropes (for example alcohols, urea), 0 to 10% by weight of water-soluble solvents (for example alcohols, glycol ethers) and optionally, among others Contain skin protection agents, dyes and fragrances. It is usually used as an approx. 1% solution in water, also undiluted for local stain removal. Ready-to-use all-purpose cleaners are also commercially available as so-called spray cleaners.

All-purpose cleaners are very often used to clean hard floor coverings such as stone, ceramic or plastic, in private households especially in the kitchen and bathroom area. The cleaning is expediently carried out preferably in the entry direction, i.e. the user works from a far end of the room towards the entrance, since the freshly wiped floor is usually wet for up to 15 minutes and cannot be walked on without staining. This poses a problem, particularly in the area of commercial building cleaning, since the freshly cleaned floor surfaces are often immediately soiled again by the public traffic, which usually lasts during the cleaning process, whereby the renewed soiling is possible the longer the slower the cleaner or its aqueous solution the floor surface dries.

From WO 96/26260 A1 (Unilever NV) aqueous cleaning agents for hard surfaces are known which contain a surfactant mixture with, based on the total amount of surfactant, (a) at least 65% by weight nonionic surfactant, (b) less than 1% by weight .-% anionic sches surfactant and (c) 0.1 to 35 wt .-% diquatemares Poiy (dimethyisiloxane) and make the surfaces hydrophobic and provided with a protective film. The agents are preferably free of anionic surfactant because it reduces the effectiveness of the agents.

DE 37 19 086 C1 (77 ?. Goldschmidt AG) and EP 0 294 642 B1 (7t ?. Goldschmidt AG) disclose diquaternary polysiloxanes, in particular diquaternary poly (dimethylsiloxanes), and their preparation and their use in cosmetic preparations, in particular for Hair care, known.

It was an object of the present invention to provide means for cleaning hard surfaces or cleaning methods which are distinguished by a faster drying of the hard surfaces which are moist after the treatment than conventional means or methods, or to identify an active ingredient which can be used for this purpose.

Surprisingly, it has now been found that these tasks are solved by using diquaternary polysiloxanes, while other polysiloxane derivatives, such as, for example, polyether siloxanes, are not able to do this, or only insufficiently.

In a first embodiment, the invention relates to an aqueous cleaning agent for hard surfaces, containing surfactant and diquaternary polysiloxane, which, based on the total amount of surfactant and diquaternary polysiloxane, contains at least 1% by weight of anionic surfactant.

The invention in a second embodiment relates to the use of diquaternary polysiloxane in a liquid cleaning agent for hard surfaces to shorten the drying time of the surface treated with the cleaning agent.

In a third embodiment, the invention relates to a method for shortening the drying time of a hard surface treated with a liquid cleaning agent, the surface being treated with a liquid cleaning agent containing diquaternary polysiloxane in concentrated or diluted form.

The invention is characterized in particular by a considerable shortening of the

Drying time compared to comparable agents or processes without the use of di-quaternary polysiloxane. In addition to this primary effect according to the invention, the diquaternary polysiloxane, as expected, unfolds the foams inherent in the silicones. dampening effect. Surprisingly, the agents according to the invention also show a cleaning capacity which is not only unimpaired by the diquaternary polysiloxane, but usually even increased, and consistently increased cold stability.

In the context of the teaching according to the invention, drying time is generally understood to mean the literal meaning, that is to say the time which elapses before a hard surface treated with a liquid cleaning agent in concentrated or diluted form has dried, but in particular the time which elapses until 90 % of a surface treated with a liquid cleaning agent in concentrated or diluted form has dried.

Substances that also serve as ingredients of cosmetic products are referred to below in accordance with the International Nomenclature Cosmetic Ingredient (INCI) nomenclature. Chemical compounds have an INCI name in English, herbal ingredients are only listed according to Linne in Latin. So-called trivial names such as "water", "honey" or "sea salt" are also given in Latin. The INCI names can be found in the "International Cosmetic Ingredient Dictionary and Handbook, Seventh Edition (1997)" published by The Cosmetic, Toiletry and Fragrance Association (CTFA), 1101, 17 ^t Street NW, Suite 300, Washington, DC 20036, USA, and has more than 9,000 INCI names and references to more than 37,000 trade names and technical names including the associated distributors from over 31 Countries. The International Cosmetic Ingredient Dictionary and Handbook assigns the ingredients one or more chemical classes, for example "Polymeric Ethers", and one or more functions (functions), for example "Surfactants - Cleansing Agents", which it in turn explains in more detail . This will also be referred to below if necessary.

Diquaternary polysiloxanes in the sense of the invention are polyorganosiloxanes (= silicones) with two quaternized organic ammonium groups, ie two quaternary nitrogen atoms, each carrying four organic radicals and each being bonded to a silicon atom of the polyorganosiloxane via one of these four radicals.

Drying time / quick drying effect

The drying time for agents E1, V1 and V2 was determined as follows. For this purpose, approximately 10 m ² large test areas of a PVC floor were wet-wiped with an aqueous solution of 30 ml of the respective agent in 5 l of water with a hardness of 17 ° d and a temperature of 40 ° C. using a professional cleaning device from Henkel Ecolab and after the wiping was completed, a trained panel determined the time that elapsed until 90% of the total area was dry. This time is given as the mean of a respective 6-fold determination (by 6 trained test persons) in the tables as the drying time in minutes.

The presence of the diquaternary poly (dimethylsiloxane) (E1) brought about a considerable reduction in drying time by 36% compared to an additive-free frame formulation (V1), while the polyether siloxane (V2) did not cause such a rapid drying effect.

E1 also showed clearly different tearing behavior compared to V1 and V2, which indicates a changed dynamic surface activity.

Cleaning ability

The cleanability of agents E1 and V1 was tested in undiluted form.

Unless otherwise stated below, the cleaning effect was tested in accordance with the quality standards for floor care and cleaning agents of the Industrial Association for Cleaning and Care Products. V. (IPP), Frankfurt / M. (Soaps - oils - fats - waxes 1986, 112, 371-372), i.e. each with 6 ml undiluted test substance and the soiling 1.

The method is based on wiping a white dirt carrier treated with test dirt under defined conditions with a sponge soaked in the test material and measuring the cleaning effect photoelectrically against the untreated white dirt carrier. A device similar to the washability and abrasion tester 494 from Erichsen GmbH, D-58675 Hemer-Sundwig, was used as the wiping device, with a brass guide rail and an 820 g weight attachment.

The whiteness measurement was carried out using a Micro-Color color difference measuring device from Dr. Lange, D-40549 Düsseldorf, performed with averaging over 21 measured values per test strip.

The cleaning power was determined in a triple determination and is given in the tables relative to the 100% cleaning power of V1.

Foaming power

The foaming power of agents E1 and V1 was determined using the pumping method. From a 3 l beaker with graduation filled with water with a hardness of 16 ° d and a temperature of 20 ° C, exactly 1 l of water was obtained using a type 8 submersible pump from Haake via a glass U-tube with an inner diameter of 6 mm into a 2 liter beaker with a diameter of approx. 14 cm, in which 6 ml of the respective agent were found, the open end of the U-tube being at a distance of 450 mm above the center of the bottom of the 2 liter beaker. The height of the foam formed was measured to the nearest 0.5 cm immediately after the pumping process and is given in cm in the tables.

Clear point

The clear point of means E1 and V1 was determined as follows. Approximately half of a weighing glass was filled with approx. 40 g of the respective agent, closed and stored in a freezer overnight at -15 ° C. The frozen sample was then thawed at room temperature, the substance being slowly stirred with the cold thermometer, so that as few air bubbles as possible were incorporated. The temperature at which the mean was just clear is given as a clear point in the tables.

The diquaternary poly (dimethylsiloxane) thus not only brought about the rapid drying effect according to the invention, but also, with sufficient foaming power - slightly dampened by the silicone - also an improvement in the low-temperature stability with unchanged high cleaning power of the agent according to the invention. Example 2

Further agents E2 to E8 according to the invention were produced on the basis of the composition V1 (see Table 1) with different contents of various diquaternary poly (dimethylsiloxanes) according to the table 2 by simply stirring the components together. All agents had a pH of 10.

The diquaternary poly (dimethyisiloxane) in the compositions E2 to E8, with sufficient foaming power - partly slightly dampened by the silicone - also brought about the additional advantages of a partially Significantly improved stability to cold and at the same time sometimes even significantly increased cleaning ability.

Example 3

Further agents E9 to E16 according to the invention and the comparative agents V3 and V4 were prepared according to Tables 3 and 4 and their viscosity with a Brookfield rotary viscometer of the type DV II using the spindle 31 at a speed of 30 min ¹ at 20 ° C. and their pH -Value determined.

Drying time / quick drying effect

For the agents, the drying time on a ceramic and a PVC surface was determined as follows. For this purpose, the respective agent was applied to an area of approximately 8 x 8 cm ² large test areas in the form of a tile or made of PVC with an airbush gun at five points. The test area was then tared on a balance and the weight loss was monitored over a period of 400 seconds. The course over time of the percentage weight of agent applied (100% at the beginning; 0% corresponds to the completely dried agent) is shown graphically in diagrams 1 and 2. Table 3
