Definitions
- the present invention relates to cleaning compositions. More particularly, the cleaning compositions according to the present invention are stable aqueous emulsions of nonionic surfactants particularly suitable for the pretreatment of laundry or the cleaning of hard surfaces.
- cleaning compositions have been described in the art.
- a particular type of cleaning compositions is described which are aqueous emulsions of a nonionic surfactant system.
- Such emulsions find a preferred application in the formulation of bleaching compositions comprising hydrogen peroxide or water soluble source thereof and a liquid hydrophobic bleach activator, or any other hydrophobic ingredient which needs to be separated from hydrogen peroxide.
- bleaching compositions comprising hydrogen peroxide or water soluble source thereof and a liquid hydrophobic bleach activator, or any other hydrophobic ingredient which needs to be separated from hydrogen peroxide.
- such emulsions can be used to formulate products which do not contain hydrogen peroxide.
- such emulsions can be useful because they allow to keep a given hydrophobic ingredient separate from the aqueous phase, with which said hydrophobic ingredient could react, e.g., by hydrolysis.
- Another advantage of such emulsions is that they provide a means to formulate ingredients with very low water solubility, without the need for using alcoholic or solvent mixtures, which are usually undesirable for aesthetic (odour) and toxicity reasons.
- aqueous emulsions of nonionic surfactants In order to manufacture such aqueous emulsions of nonionic surfactants, it is necessary to vigorously mix the ingredients together. During this vigorous mixing, lots of air bubbles are generated which are detrimental both to the composition's aesthetics and stability. Indeed, surfactants tend to concentrate at the air/liquid interfaces generated by said air bubbles. Thus the more air bubbles a composition contains, the less surfactants will be available for the stabilisation of the droplets of the dispersed phase. This problem of air bubbles is aggravated in that aqueous emulsions of nonionic surfactants are pseudoplastic fluids, i.e. they have a higher viscosity at low shear rates. Consequently, the air bubbles generated upon mixing, i.e.
- aqueous emulsions of nonionic surfactants which comprise silicone compounds.
- silicone compounds reduce the viscosity of aqueous emulsions comprising a nonionic surfactant system whatever the viscosity was before their addition and allow to substantially eliminate the air bubbles.
- emulsions comprising silicone compounds are physically more stable than emulsions without said silicone compounds.
- the present invention allows for greater flexibility in formulating and provides stable aqueous emulsions suitable to be used in the most efficient manner by the consumer.
- silicone compounds are unexpected and beneficial as said silicone compounds are only known in the context of laundry compositions as sud-suppressing agents, see for instance US 4 076 648, US 4 021 365, US 4 749 740, US 4 983 316, EP 150 872, EP 217 501 and EP 499 364.
- the addition of silicone compounds according to the present invention to the nonionic surfactant system used to emulsify hydrophobic liquid ingredients as for instance bleach activators improves the storage stability of hydrogen peroxide.
- the present invention is a stable aqueous emulsion having a pH of from 0.5 to 6, comprising a hydrophilic nonionic surfactant and a hydrophobic nonionic surfactant, said stable aqueous emulsion further comprises an effective amount of silicone compounds.
- compositions according to the present invention are stable aqueous emulsions of nonionic surfactants.
- stable emulsion it is meant an emulsion which does not substantially separate into distinct layers, upon standing for at least 2 weeks at 50 °C.
- compositions according to the present invention are aqueous. Accordingly, the compositions according to the present invention comprise from 10% to 95% by weight of the total composition of water, preferably from 30% to 90%, most preferably from 60% to 80%. Deionized water is preferably used.
- the compositions according to the present invention are emulsions of nonionic surfactants. Said emulsions of nonionic surfactants comprise at least two nonionic surfactants. Said two nonionic surfactants in order to form emulsions which are stable must have different HLB values (hydrophilic lipophilic balance) , and preferably the difference in value of the HLBs of said two surfactants is at least l, preferably at least 3. By appropriately combining at least two of said nonionic surfactants with different HLBs in water, emulsions according to the present invention will be formed.
- HLB values hydrophilic lipophilic balance
- nonionic surfactant with an HLB above 11 (herein referred to as hydrophilic nonionic surfactant)
- nonionic surfactant with an HLB below 10 herein referred to as hydrophobic nonionic surfactant
- Suitable nonionic surfactants for use herein include alkoxylated fatty alcohols. Indeed, a great variety of such alkoxylated fatty alcohols are commercially available which have very different HLB values.
- the HLB values of such alkoxylated nonionic surfactants depend essentially on the chain length of the fatty alcohol, the nature of the alkoxylation and the degree of alkoxylation. Hydrophilic nonionic surfactants tend to have a high degree of alkoxylation and a short chain fatty alcohol, while hydrophobic surfactants tend to have a low degree of alkoxylation and a long chain fatty alcohol.
- Surfactants catalogues are available which list a number of surfactants including nonionics, together with their respective HLB values.
- compositions according to the present invention comprise from 2 % to 50 % by weight of the total composition of said hydrophilic and hydrophobic nonionic surfactants, preferably from 5 % to 40 %, most preferably from 8 % to 30%.
- T he compositions according to the present invention may f urt h er comprise other nonionic surfactants which should however not significantly alter the weighted average HLB value of the overall composition.
- compositions according to the present invention further comprise as an essential element an effective amount of silicone compounds.
- effective amount it is meant an amount of silicone compounds which is sufficient to reduce and substantially eliminate the air bubbles generated in the aqueous emulsions according to the present invention.
- effective amount'* it is also meant an amount of silicone compounds which is sufficient to provide physically stable aqueous emulsions wherein the viscosity can be conveniently controlled.
- the compositions according to the present invention comprise from 0.01 % to 5 % by weight of the total composition of said silicone compounds, more preferably from 0.1 % to 2 %.
- compositions obtained according to the present invention have a viscosity of from 100 cps to 3000 cps at 50 rpm shear rate at 25 °C, more preferably from 300 cps to 1500 cps, measured by a Brookfield DV II rotational viscosimeter.
- said silicone compounds substantially reduce and preferably substantially eliminate the air bubbles generated either during the manufacture of said emulsions or when pouring or shaking said emulsions, thereby providing aqueous emulsions which are acceptable for aesthetics and stability.
- silicone has become a generic term which encompasses a variety of relatively high- molecular-weight polymers containing siloxane units and hydrocarbyl groups of various types. Indeed, silicone compounds have been extensively described in the art, see for instance US 4 076 648, US 4 021 365, US 4 749 740, US 4 983 316, EP 150 872, EP 217 501 and EP 499 364. The silicone compounds disclosed therein are suitable in the context of the present invention. Generally, the silicone compounds can be described as siloxanes having the general structure :
- n is from 20 to 2.000, and where each R independently can be an alkyl or an aryl radical. Examples of such substituents are methyl, ethyl, propyl, isobutyl, and phenyl.
- Preferred polydiorganosiloxanes are polydimethylsiloxanes having trimethylsilyl endblocking units and having a viscosity at 25°C of from 5 x 10 ⁇ 5 m 2 /s to 0.1 m 2 /s i.e. a value of n in the range 40 to 1500. These are preferred because of their ready availability-, and their relatively low cost.
- a preferred type of silicone compounds useful in the compositions herein comprises a mixture of an alkylated siloxane of the type hereinabove disclosed and solid silica.
- the solid silica can be a fumed silica, a precipitated silica or a silica made by the gelformation technique.

Typically, the compositions according to the present invention comprise from 0.5% to 20% by weight of the total composition of hydrogen peroxide, preferably from 2% to 15%, most preferably from 3% to 10%. Preferred compositions according to the present invention further comprise a bleach activator. By bleach activator, it is meant herein any compound which reacts with hydrogen peroxide to form a peracid.
- bleach activators such hydrophobic bleach activators typically belong to the class of esters, amides, imides, or anhydrides.

- acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator.
- the term bleach activator includes mixtures of bleach activators.
- the nonionic surfactant system to be chosen to emulsify said bleach activator depends on the HLB value of said bleach activator.
