Definitions
- the present invention relates to an additive composition with integrated action.
- the present invention falls within the technical field of additives for washings in washing-machines, i.e. products that are substantially washing adjuvants that integrate the use of detergents, with a specific function, different from the cleaning action itself of detergents: examples of these additives are stain-removing additives, softeners, colour additives, whiteners, anti-lime additives, antibacterial agents, bleaches, perfuming agents, etc. etc.
- Additive products to be used in addition to the detergent and that can exert various functions are in fact known and widely marketed.
- additives are added in the pre-washing or washing phase, as is the case for example of stain-removing additives, bleaches, anti-lime additives, antibacterial agents, whereas other additive products are added in the final washing phase, i.e. in the last rinse: this is the case of softeners and, in some cases, also antibacterial agents.
- the different addition time of the additive product depends on its physico-chemical characteristics and its function: it is clear, in fact, that a softener must be added in the final washing stage to prevent losing or minimizing the desired softening and perfuming effect due to the subsequent rinsing phases of the clothes. More specifically, a softener acts in the following way: the molecules of the softening product become bound to the fibers of the fabrics, creating a thin film and the final effect is a greater softness of the garment, combined with its possible fragrance and, again thanks to the composition of the softening product and reduction in friction between the fibers, said additive also facilitates the ironing of the garment.
- the use of the softening product also reduces the static electricity of the freshly washed garments.
- Softeners are therefore substantially washing adjuvants that integrate the use of detergents.
- the composition of softeners comprises the use of quaternary ammonium compounds with one or more fatty chains.
- softening additives used in the past are DSDMAC (distearyldimethylammonium chloride), DHTDMAC (di-hydrogenated tallow dimethylammonium chloride).
- DSDMAC disearyldimethylammonium chloride
- DHTDMAC di-hydrogenated tallow dimethylammonium chloride
- the composition of all the main softeners on the market comprises esterquat (inci definition: Distearoylethyl Hydroxyethylmonium Methosulfate), as essential component: these are positively charged softening molecules, obtained by the esterification of ethoxylated quaternized amines with long-chain fatty acids.
- the other components are almost always additives, fragrances, thickeners or pearling agents, dyes, etc.
- a stain-removing additive is in fact generally used by applying it directly to the garment and specifically on the stain to be treated, before washing, or it is generally added as additive in the pre-washing or washing phase in the washing cycle of the washing machine.
- composition of liquid stain-removing additives is generally based on an appropriate mixture of nonionic, anionic, amphoteric surfactants, amine oxide, enzymes or hydrogen peroxide or other oxidizing agents, such as, for example, sodium hypochlorite (the latter only to be used on white garments).
- multifunction or with integrated action have been recently introduced onto the market, i.e. products characterized by contemporaneously exerting two or more functions among those previously listed: colour and anti-lime additives, stain-removers and bleaches, softeners and optical whitening agents, etc., can in fact be found on the market, in addition to the "obvious" softening and perfuming additive.
- Multifunction additives that combine the softening action to be exerted in the last rinsing phase with the stain-removing or bleaching action (for example), which, by their very nature, are exerted in different phases of the washing cycle (pre-washing or actual washing), are neither known nor commercialized: these additives with a stain-removing or bleaching action are in fact ineffective if added in the final rinsing phase. Furthermore, on the basis of the compositional characteristics of softening additives which, as previously indicated, have esterquat as basic ingredient, their co-existence with the stain-removing/cleaning components of stain-removing additives which would completely deactivate the softening action of the softening additive based on esterquat, appears impossible.
- the main objective of the present invention is therefore to find a liquid additive composition with integrated action, that can simultaneously exert a softening and cleaning/stain-removing function.
- a further objective of the present invention is also to find a liquid additive composition with integrated action, that can simultaneously exert a softening and cleaning/stain-removing function when added in the final rinsing phase of the washing cycle of a washing machine, i.e. when added to the compartment/space of the softener in the washing machine.
- the object of the present invention therefore relates to a liquid additive composition with integrated action, said composition being characterised in that it comprises:
- the liquid additive composition with integrated action preferably has a pH lower than 6.
- the cleaning/stain-removing component (i) of the liquid additive composition with integrated action preferably consists of:
- the cleaning/stain-removing component consists, as performance booster, of a mixture of alkoxylated polyethyleneimine and alkyl-(hydroxyethyl) dimethyl ammonium chloride in a quantity ranging from 0.1% to 5% by weight, even more preferably in a quantity equal to 2.5% by weight.
- the cleaning/stain-removing component preferably comprises an anionic surfactant in a quantity ranging from 0.1% to 5% by weight by weight and a nonionic surfactant in a quantity ranging from 0.1% to 5% by weight.
- the performance booster ensures a cleaning/stain-removing action with a reduced percentage of active ingredients in the composition, maximizing the effectiveness of said surfactants.

Description
- The present invention relates to an additive composition with integrated action.
- The present invention falls within the technical field of additives for washings in washing-machines, i.e. products that are substantially washing adjuvants that integrate the use of detergents, with a specific function, different from the cleaning action itself of detergents: examples of these additives are stain-removing additives, softeners, colour additives, whiteners, anti-lime additives, antibacterial agents, bleaches, perfuming agents, etc. etc.
- Additive products to be used in addition to the detergent and that can exert various functions are in fact known and widely marketed.
- These additive products are added according to their characteristics and function at different times/stages of the washing process of clothes in a washing machine.
- Certain additives are added in the pre-washing or washing phase, as is the case for example of stain-removing additives, bleaches, anti-lime additives, antibacterial agents, whereas other additive products are added in the final washing phase, i.e. in the last rinse: this is the case of softeners and, in some cases, also antibacterial agents.
- As previously indicated, the different addition time of the additive product depends on its physico-chemical characteristics and its function: it is clear, in fact, that a softener must be added in the final washing stage to prevent losing or minimizing the desired softening and perfuming effect due to the subsequent rinsing phases of the clothes. More specifically, a softener acts in the following way: the molecules of the softening product become bound to the fibers of the fabrics, creating a thin film and the final effect is a greater softness of the garment, combined with its possible fragrance and, again thanks to the composition of the softening product and reduction in friction between the fibers, said additive also facilitates the ironing of the garment.
- The use of the softening product also reduces the static electricity of the freshly washed garments.
- Softeners are therefore substantially washing adjuvants that integrate the use of detergents. Historically, the composition of softeners comprises the use of quaternary ammonium compounds with one or more fatty chains. Examples of softening additives used in the past are DSDMAC (distearyldimethylammonium chloride), DHTDMAC (di-hydrogenated tallow dimethylammonium chloride). Nowadays, the composition of all the main softeners on the market comprises esterquat (inci definition: Distearoylethyl Hydroxyethylmonium Methosulfate), as essential component: these are positively charged softening molecules, obtained by the esterification of ethoxylated quaternized amines with long-chain fatty acids. The other components are almost always additives, fragrances, thickeners or pearling agents, dyes, etc.
- It is also evident that the moment of use of a stain-removing additive, again referring to a washing adjuvant that integrates the use of detergents, is substantially different from that of the softening additive described above.
- A stain-removing additive is in fact generally used by applying it directly to the garment and specifically on the stain to be treated, before washing, or it is generally added as additive in the pre-washing or washing phase in the washing cycle of the washing machine.
- The composition of liquid stain-removing additives is generally based on an appropriate mixture of nonionic, anionic, amphoteric surfactants, amine oxide, enzymes or hydrogen peroxide or other oxidizing agents, such as, for example, sodium hypochlorite (the latter only to be used on white garments).
- In order to facilitate the task of the end user, various products called "multifunction" or with integrated action have been recently introduced onto the market, i.e. products characterized by contemporaneously exerting two or more functions among those previously listed: colour and anti-lime additives, stain-removers and bleaches, softeners and optical whitening agents, etc., can in fact be found on the market, in addition to the "obvious" softening and perfuming additive.
- The production of these "multifunction" compositions or additives is not as easy and trivial as might seem to the eye of a simple user. Skilled persons in the field, in fact, are well aware of the difficulties encountered in producing these additives as the ingredients used for one function are often in conflict with those that exert other functions and their combination can lead to a partial/total inactivity of the end-product in one or more of the desired functions.
- It is also evident that the production of an effective "multifunction" additive has a further fundamental basic requirement: not only must the physico-chemical characteristics of the various components be such as to allow the stability and functioning of the final additive for each function desired, but the functions of the "multifunction" additive must also be contemporaneous, i.e. they must be functions that are exerted in the same washing phase(s). The multifunction additives currently on the market are in fact specifically additives that combine two or more additive functions which, in the past, were added individually and separately in the same washing stage of the garment.
- Multifunction additives that combine the softening action to be exerted in the last rinsing phase with the stain-removing or bleaching action (for example), which, by their very nature, are exerted in different phases of the washing cycle (pre-washing or actual washing), are neither known nor commercialized: these additives with a stain-removing or bleaching action are in fact ineffective if added in the final rinsing phase. Furthermore, on the basis of the compositional characteristics of softening additives which, as previously indicated, have esterquat as basic ingredient, their co-existence with the stain-removing/cleaning components of stain-removing additives which would completely deactivate the softening action of the softening additive based on esterquat, appears impossible.
- The Applicant has now surprisingly found a liquid additive composition with integrated action, which overcomes the drawbacks of the state of the art.
- The main objective of the present invention is therefore to find a liquid additive composition with integrated action, that can simultaneously exert a softening and cleaning/stain-removing function.
- A further objective of the present invention is also to find a liquid additive composition with integrated action, that can simultaneously exert a softening and cleaning/stain-removing function when added in the final rinsing phase of the washing cycle of a washing machine, i.e. when added to the compartment/space of the softener in the washing machine.

and with a pH equal to about 3.0. - The liquid additive composition with integrated action according to the present invention previously described has the considerable and surprising advantage of combining both the softening/perfuming function and the cleaning/stain-removing function in a single additive, a combination which was previously considered impossible, not only for reasons of incompatibility of the ingredients that exert single functions in known "single" additives, but also due to functioning times in the washing cycle that are completely different for the various additives.
- A cleaning/stain-removing additive according to the known art, in fact, necessarily requires washing times, temperatures and dilutions that are completely different from the times, temperatures and dilutions required by a softening/perfuming additive which is added in the last rinse of the whole washing cycle.
- It is in fact completely unexpected and surprising that the additive composition with integrated action according to the present invention, when added in the last rinse, is also capable of exerting its specific cleaning/stain-removing function, i.e. capable of effectively ensuring a cleaning action under said time, temperature and dilution conditions, without simultaneously annulling the softening/perfuming action.
- A further object of the present invention relates to the use of said liquid additive composition with integrated action, as softening, perfuming, cleaning and/or stain-removing agent, by adding the additive composition in the final washing stage of one or more garments and, more specifically, by addition in the last rinsing phase. This addition is preferably effected by inserting the liquid additive composition with integrated action according to the present invention in the compartment/space of the washing machine normally used for the insertion of softening additives, i.e. additives adopted by the washing machine in the last rinsing phase.
- Another object of the present invention also relates to the process for preparing the liquid additive composition with integrated action according to the present invention, which requires a precise and specific sequence of steps, carried out in the exact order described and claimed hereunder.
- The process for obtaining a liquid additive composition with integrated action according to the present invention comprises the following operating steps in the order indicated hereunder:
- a) dissolving any preservative components and the sensory component, in water, under stirring and until complete dissolution;
- b) subsequently adding, in succession and awaiting complete dissolution, the performance boosters, the anionic surfactant and an acid with a pK lower than 6;
- c) pre-mixing, separately, the components in powder form, in the absence of water, namely the nonionic surfactant, any fragrance in powder form, the softening component, modified guar gum and/or its derivatives, a possible viscosifying agent such as cellulose and/or derivatives thereof; and adding said pre-mixture, kept under vigorous stirring, to the solution resulting from step b), until complete dissolution;
- d) pre-mixing, separately, a possible anti-foaming agent and the amino-modified polysiloxane softening component, in the presence of water, and adding said pre-mixture to the solution resulting from step c), until complete dissolution;
- e) subsequently adding, in succession and awaiting complete dissolution, the softening component comprising quaternary silicones and possible dyes;
- f) pre-mixing, separately, a possible opacifying agent which is a styrene/acrylic copolymer, and water and adding said pre-mixture, to the solution resulting from step e), until complete dissolution;
- g) subsequently adding, in succession and until complete dissolution, any possible suspending and viscosifying agents and water up to the complement to 100.
- In order to obtain a stable and effective liquid additive composition with integrated action, it is important that the ingredients be added in the order specified and that each subsequent component or pre-mixture be added only when all the other components are perfectly dissolved.
- In particular, the fragrance microcapsules must be added in the first step of the process and directly in water to improve their suspension, dispersion and consequent stability. The order of addition of the surfactants is also important and must be as specified above in order to obtain the maximum homogeneity and facilitate their insertion in the formulation. The citric acid must be added in step b) indicated above, as, if added subsequently, it favours the browning of the bulk. The addition of citric acid before the fragrance, in fact, prevents colour change, increasing the stability, and also facilitates the insertion of the cationic guar gum.
- Step c) for pre-mixing the powders, in the absence of water, with fragrance and nonionic surfactant, is fundamental for homogeneously inserting the same powders into the formulation. Powders in direct contact with water would in fact form clots which are very difficult to dissolve.
- The formation of the subsequent pre-mixture of step d) also allows the amino-modified polysiloxane softening component to begin to become dispersed in water (about 1% by weight), improving the homogeneity of the dispersion of the same in the final additive composition.
- The suspending agent must be added in the final step due to the fact that, as it has both a suspending effect and a viscosifying effect, if it were added in the previous steps, it would jeopardize the homogeneous distribution of all the other raw materials added subsequently. The water for integrating the volume is added at the end of the process to ensure that there are no residues of suspending agent that have not been perfectly dispersed.
- In addition to the advantages previously indicated, the fundamental advantage of the additive composition with integrated action according to the present invention lies in the fact that, thanks to the particular combination of components forming the additive composition, it is capable of obtaining optimum results in terms of softness and fragrance of the dry garment, exerting a further cleaning action specifically in the final step, as demonstrated in the following examples, with the use of an extremely reduced quantity of surfactant (less than 10% by weight).
- The following examples are provided for purely illustrative purposes.
- The composition according to the present invention, having the formulation indicated in the following Table 1, was prepared using the preparation process previously described for liquid additive compositions with integrated action.

- The softness evaluation test was carried out on a sample of 50 women having the following characteristics: 50% of the women were aged between 25 and 40 years old and 50% of the women were aged between 41 and 61 years old, all from a middle/high social class, and all 100% responsible for purchasing for and cleaning their own homes, 100% users of softeners, and 100% users of or not contrary to liquid additives/gels for laundry.
- The test is carried out on two washed towels, inserting the two different products object of the comparison in the softener compartment and asking the sample of women to put the two towels in order of softness.
- The results are indicated in
Figure 2 and are expressed as the sum of the results attributed by the users to the softness of the towels washed with each product (B is the product according to the present invention, whereas D is the comparative product). - The softness profile of the liquid composition of Table 1 with integrated action proved to be substantially comparable to the softness profile of the commercial product Fabuloso® (the difference is not statistically relevant).
