Definitions
- the invention relates to surfactant-containing foams, processes for the preparation of surfactant-containing foams and packaged products containing surfactant-containing foams.
- Surfactant-containing agents are known in a wide variety of forms. Thus, the consumer knows solid, for example tablet-shaped or granular detergents and liquid or gel-based cleaners for hard surfaces. Also known are agents, such as detergent or
- Hand soaps which are present in the packaging in the liquid state, but the consumer before use by means of an intumescent metering device converted into a foam and dosed directly into the rinse water or in the palm of the hand (for
- Dishwashing agent for example, WO 2007/003302 A1.
- Some bath cleaners are also sprayed directly onto the surfaces to be treated as foam using special foam spray nozzles. Also, shaving foam is foamed until the dosage by the consumer.
- the surfactant-containing foams hitherto known to the consumer are accordingly always produced by the consumer only directly before application from a foamable liquid product and a two-component pump.
- An advantage of this dosage form is that the foamable liquid product - in addition to the presence of foam-forming substances such as surfactants - no special requirements are made. Almost every usual
- Detergent formulation should be capable of being converted into a short-term stable, flowable foam by means of a suitable pumping device.
- a significant disadvantage is that the e.g. the amount required by a detergent for a single wash load is so great that it can not readily be foamed with a manually operated pump, as this would be either too strenuous, because too many pump surges would have to be performed or such a large pump would be used would have, which would be too expensive for single use and therefore would have to be used several times. It is doubtful whether the consumer would be willing to buy an expensive pump, which he would have to constantly mount on new storage containers to avoid new costs and waste.
- foams are particularly interesting for the consumer in the field of surfactant-containing agents, detergents and cleaning agents on the one hand, but also cosmetics on the other hand.
- the consumer expects delicacy, gentleness, protection and care from a foam, but also improved stain removal performance, since he assumes, for example, that foam adheres to a polluted surface for longer or more intensively than, for example, a low-viscosity liquid and thus can last longer.
- foams are thermodynamically unstable and at best low-viscosity liquids can be temporarily stabilized by the use of surface-active substances, it has hitherto not been possible to offer the consumer a long-term stable surfactant-containing foam which, moreover, is preferably flowable.
- a foam in the sense of the present invention is understood as meaning a disperse system of a gas or gas mixture in a continuous liquid phase, ie a structure of gas-filled cells, which are bounded by liquid cell webs.
- liquid phase is used here for the fluid of the cell bridges.
- the object is achieved by a surfactant-containing foam whose liquid phase a
- Liquid phase and gas phase separates, as a surfactant-containing foam whose liquid phase has no yield point.
- the yield stress is the highest shear stress below which a substance behaves like an elastic solid or, conversely, the smallest shear stress above which a plastic substance behaves rheologically like a liquid.
- the procedure was as follows: The sample was in the rheometer (rotational rheometer from TA-Instruments, type AR G2, schubschreibskontrolliert.es rheometer, cone-plate measuring system with 40 mm
- the shear stress was increased in a period of 30 minutes from the smallest possible value (for example 0.01 Pa) to a value above the expected yield value (eg 80 Pa).
- the deformation / sample is measured.
- the data are plotted in a log log plot (log / against log ⁇ ).
- the yield point if present, can be recognized by a sudden change in the slope of the curve.
- the sample reacts purely elastically and the slope of the curve is ideally one.
- the yield point is determined from the intersection of the tangents to both curve sections.
- the yield point of the liquid phase is at least 0.1 Pa, more preferably at least 1 Pa and in particular at least 2 Pa.
- the leakage of the liquid phase from the cell webs is particularly well prevented, so that the cell web thickness kept constant, the separation of the surfactant-containing foams in liquid phase and gas phase prevented and thus the long-term stability of the surfactant-containing foams
- a particularly advantageous and appealing aesthetics of the surfactant-containing foam and a further improvement in the storage stability can be achieved if the liquid phase per se at a shear rate of 10 s " and a temperature of 20 ° C has a viscosity of 0, 1 to 50 Pas
- the viscosity of the liquid phase is particularly preferably from 1 to 20 Pas, in particular from 2 to 10 Pas
- the surfactant-containing foam containing the liquid phase is pourable, which corresponds to a particularly preferred embodiment of the present invention, since the consumer is the foam
- the adjustment of the viscosity in this range also contributes to stabilizing the cell webs and thus increasing the long-term stability of the particular surfactant-containing foam determined, w as described above for the yield point. However, it is worked in a program and with a plot in which the viscosity is given as a function of the shear rate.
- the liquid phase preferably contains one or more thickeners and / or is in the form of a liquid-crystalline surfactant phase, preferably a lamellar surfactant phase.
- Suitable thickeners from the group of naturally occurring polymers are, for example, agar-agar, carrageenan, tragacanth, gum arabic, alginates, pectins, polyoses, guar flour, locust bean gum, starch, dextrins, gelatin and casein.
- Modified natural products come mainly from the group of modified starches and celluloses, examples which may be mentioned here carboxymethylcellulose and other cellulose ethers, hydroxyethyl and propylcellulose and core flour ethers.
- microfibrillar bacterial celluloses are suitable.
- thickeners which find wide use in a variety of applications, are the fully synthetic polymers such as polyacrylic and Polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides and polyurethanes. Also suitable and preferred is xanthan.
- Lamellar surfactant phases are on a microscopic scale two-phase systems in which surfactant bilayers are arranged as parallel lamellae. These lamellae alternate with an aqueous phase. Macroscopically they usually form an opaque gel-like, single-phase system. The surfactant bilayers of a lamellar phase can be "stacked" in parallel, with mesoscopic domains having the same orientation or being spherically “wound up". The latter systems are called vesicles or spherulites. Lamellar surfactant phases can be formed when a surfactant system is mixed with inorganic salt and optionally a cosurfactant. At sufficiently high concentration, many surfactants form lamellar phases even without salt and co-surfactant, but these are usually too viscous for the present invention and there is no flowable foam.
- a lamellar liquid phase with yield point is obtained, which can be used to form long-term stable surfactant-containing foams.
- a co-surfactant is understood to mean an amphiphilic molecule which has a particularly small hydrophilic head group compared to conventional surfactants, for example a fatty alcohol, a fatty acid, a monoglyceride or a low ethoxylated fatty alcohol with less than or equal to 3 mol ethylene oxide.
- Co-surfactants are usually very poorly soluble in water alone, but are incorporated in the presence of soluble surfactants in their micellar aggregates and affect their shape. For example, they may be suitable
- Concentration ratios induce the transition to a lamellar phase.
- This surfactant-containing liquid phase is able without the addition of a polymeric thickener in a position to form a long-term stable surfactant-containing foam.
- the ability to dispense with polymeric thickener not only has the advantage that the funds can be made easier and cheaper, but also undesirable side effects of a polymeric thickener, such as graying in the treatment of textiles, can be avoided. Accordingly, in a preferred embodiment, the surfactant-containing liquid phase is free of polymeric thickeners.
- the surfactant-containing liquid phase having yield value contains 8 to 25 wt .-% of an inorganic salt, wherein also preferably the ratio of total amount of contained in the liquid phase anionic and nonionic surfactant to inorganic salt in the range of 1, 4: 1 to 1 : 1 is.
- the liquid phase with yield value contains 0.5 to 10 wt .-% of an inorganic salt and 0.5 to 5 wt .-% of a co-surfactant, preferably selected from the group consisting of alkoxylated C 8 -C 18 - fatty alcohols having a degree of alkoxylation ⁇ 3, aliphatic C 6 -C 4 alcohols, aromatic C 6 -C 4 alcohols, aliphatic C 6 -C 2 - dialcohols, monoglycerides of C 12 -C 18 fatty acids, diglycerol ethers of C 8 .C 18 fatty alcohols and mixtures thereof.
- a co-surfactant preferably selected from the group consisting of alkoxylated C 8 -C 18 - fatty alcohols having a degree of alkoxylation ⁇ 3, aliphatic C 6 -C 4 alcohols, aromatic C 6 -C 4 alcohols, aliphatic C 6 -C 2 - dialcohols, monoglycerides
- the foam in order to be able to ensure a sufficiently high concentration of surfactant contained in the liquid phase and other optionally contained ingredients and thus a sufficient washing, cleaning or care performance, the foam preferably contains 10 to 60
- volume% gas and 40 to 90% by volume liquid phase contains 20 to 50% by volume of gas and 50 to 80% by volume of liquid phase.
- a product containing less than 10% by volume of gas and should be referred to as a discrete gas-bubble liquid product, does not have the benefit of improved adhesion to a soiled surface.
- the consumer does not recognize a product with less than 10% gas phase as a foam and combines with the appearance of a
- Liquid product with individual dispersed gas bubbles does not have the properties delicacy, softness, protection and care as is the case for a foam with a gas volume fraction of, for example, 20% or even 40%. Therefore, surfactant-containing foams having at least 10% by volume of gas are preferred. Foams containing more than 60% by volume of gas have such a low proportion of washing, cleaning or care-active ingredients that the hoped for
- Treatment success may or may not be expected to be challenged by the consumer.
- the consumer no longer perceives such a "dry foam” as a wet foam, which can provide a satisfactory cleaning or care performance due to a high amount of cleaning and / or care substances
- "dry foams" with less than 40% by volume % Liquid phase also not preferred embodiments of the present invention.
- the surfactant-containing foam preferably has a density of 400 to 900 g / l, in particular of 500 to 800 g / l. It has been found that with gas bubble sizes of 10 ⁇ m to 3 mm, the best possible aesthetics can be achieved, which corresponds to the appearance of a surfactant-containing foam. For bubble sizes below 10 ⁇ a viewer can no longer recognize the bubbles with the naked eye as such. The perception then corresponds more to a homogeneous paste. With a bubble size of more than 3 mm, the product is again more like a liquid with individual gas bubbles than a foam, especially for smaller proportions of gas. By doing
- Bubble diameters of at least 50 ⁇ m are particularly preferred according to the invention, since the consumer can perceive correspondingly large bubbles very well as bubbles; with small bubbles, this is more difficult, especially from a distance. It is also preferred that the gas bubbles diameter below 1000 ⁇ , in particular below 800 ⁇ , since the stabilization of small bubbles is easier. To stabilize small bubbles, a lower yield strength of the liquid phase is required than to stabilize larger bubbles. Accordingly, to set the lower yield point, less thickener or less inorganic salt and optionally co-surfactant must be used to stabilize smaller gas bubbles compared to larger gas bubbles. Accordingly, the gas bubbles of the foam with preference a diameter of 10 ⁇ to 3 mm, preferably from 20 to 1000 ⁇ , more preferably from 50 to 800 ⁇ and in particular from 100 to 500 ⁇ on.

- a detergent with the following composition was prepared:
- the formulation E1 according to the invention was a lamellar phase and had a yield point.
- the comparative formulation V1 was an isotropic L1 phase without yield stress.
- the comparative formulation V1 separated within a few hours in a liquid phase and a water poorer foam phase.
- the formulation E1 according to the invention had no leakage of the foam and no separation of a liquid phase when stored at room temperature over a period of several weeks. Only an increase in bubble size was observed. However, the visual appearance of a single-phase foam was retained.
- Example 2
- formulation E2 2% by weight of n-hexadecanol (formulation E2) were stirred into the formulation E1 according to the invention at 60 ° C. Then, at 50 to 60 ° C, the formulations E1 and E2 as described in Example 1 foamed to a foam of 60% by volume of liquid phase and 40% by volume of air.
- the initial bubble size distribution of the foams was identical. Thereafter, the foams were cooled to room temperature and filled into cuvettes for photographing the bubble size. After 4 weeks of storage at 20 ° C, the foam of the formula E2 had a much narrower gas bubble size distribution than the foam of the formula E1.
