This application is a divisional of U.S. application Ser. No. 12/674,172, filed Feb. 19, 2010, granted which is a national stage of PCT/EP2008/060796, filed Aug. 18, 2008, the contents of both herein incorporated entirely by reference.
The present invention relates to the use of merocyanine compounds having an absorption maximum of 350 to 400 nm and 2-hydroxyphenyl benzotriazole UV filters for the protection of body care and household products against the deleterious effects of light, heat and oxygen.
The present invention also relates to a mixture of at least one merocyanine having an absorption maximum of 350 to 400 nm and of at least one 2-hydroxyphenyl benzotriazole UV filter and optionally at least one excited state quencher.
Since consumers can choose from a large variety of Home & Personal Care products, producers need to communicate clearly how their brands are unique. Sophisticated products containing new fragrances and actives in many colourful formulations, displayed in transparent and translucent packaging are very common.
It is mandatory for commercial success that the pleasant appearance, product efficacy and the fresh smell of a consumer product will last during its whole product life cycle even when exposed heavily to UV-light. This exposure can result in decomposition processes and strong color fading destroying the product appearance, active ingredients and fragrances.
Various stabilization techniques of clear packaged products by absorption of UV light are commonly used and well known. For example broad-band UV light stabilizers of the benzotriazole class enhance product's stability and shelf live due to their very good UV-A and UV-B absorption properties.
The most effective stabilizers known as of today to prevent or delay light induced fading of transparent packaged products are e.g. benzotriazoles like known under the trade names Ciba TINOGARD HS or Ciba TINOGARD TL. These proved to be very effective, due to their broadband absorption properties and strong extinction in the UV-A range.
WO 2004/006878, WO 2005/058269, WO 2006/016806 A1, WO 2006/009451, WO 2006/125676 A1 and WO 2006/032741 A1 disclose merocyanine UV-A absorbers and their use for protecting human and animal hair and skin from UV radiation as well as their application in cosmetic and dermatological formulations.
WO 2007/014848 discloses various merocyanine structures which have superior properties in stabilizing cosmetic and dermatological formulations and household products.
These references also describe that the merocyanine UV absorbers can be mixed with any other UV filter substance.
It was now surprisingly found that the combination of specific merocyanine derivatives which have an absorption maximum in the range of 350 to 400 nm with benzotriazole UV-B filters and optionally with at least one excited state quencher have outstanding stabilizing properties.
Therefore, the present invention relates to the use of stabilizing composition comprising
- (a) an effective stabilizing amount of at least one merocyanine derivative having an absorption maximum of 350 to 400 nm, and
- (b) at least one UV filter selected from benzotriazole derivatives; and optionally
- (c) at least one excited state quencher; and optionally
- (d) a salicylate;
for the protection of body care and household products against the deleterious effects of light, heat and oxygen.

Deodorizing Active IngredientsAs deodorizing active ingredients are for example, antiperspirants, for example aluminium chlorohydrates (see J. Soc. Cosm. Chem. 24, 281 (1973)). Under the trade mark Locronâ of Hoechst AG, Frankfurt (FRG), there is available commercially, for example, an aluminium chlorohydrate corresponding to formula Al2(OH)5Cl×2.5 H2O, the use of which is especially preferred (see J. Pharm. Pharmacol. 26, 531 (1975)). Besides the chlorohydrates, it is also possible to use aluminium hydroxyacetates and acidic aluminium/zirconium salts. Esterase inhibitors may be added as further deodorizing active ingredients. Such inhibitors are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and especially triethyl citrate (Hydagen CAT, Henkel), which inhibit enzyme activity and hence reduce odor formation. Further substances that come into consideration as esterase inhibitors are sterol sulfates or phosphates, for example lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester and hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester. Antibacterial active ingredients that influence the germ flora and kill or inhibit the growth of sweat-decomposing bacteria can likewise be present in the preparations (especially in stick preparations). Examples include chitosan, phenoxyethanol and chlorhexidine gluconate. 5-chloro-2-(2,4-dichlorophenoxy)-phenol (Triclosan, Irgasan, Ciba Specialty Chemicals Inc.) has also proved especially effective.

Hydrotropic AgentsFor improvement of the flow behavior it is also possible to employ hydrotropic agents, for example ethoxylated or non ethoxylated mono-alcohols, diols or polyols with a low number of carbon atoms or their ethers (e.g. ethanol, isopropanol, 1,2-dipropanediol, propyleneglycol, glycerin, ethylene glycol, ethylene glycol monoethylether, ethylene glycol monobutylether, propylene glycol monomethylether, propylene glycol monoethylether, propylene glycol monobutylether, diethylene glycol monomethylether; diethylene glycol monoethylether, diethylene glycol monobutylether and similar products). The polyols for that purpose comprise preferably 2 to 15 carbon atoms and at least two hydroxy groups. The polyols may also contain further functional groups, especially amino groups, and/or may be modified with nitrogen. Typical examples are as follows: glycerol, alkylene glycols, for example ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol and also polyethylene glycols having an average molecular weight of from 100 to 1000 Dalton; technical oligo-glycerol mixtures having an intrinsic degree of condensation of from 1.5 to 10, for example technical diglycerol mixtures having a diglycerol content of from 40 to 50% by weight; methylol compounds, such as, especially, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol; lower alkyl-glucosides, especially those having from 1 to 8 carbon atoms in the alkyl radical, for example methyl and butyl glucoside; sugar alcohols having from 5 to 12 carbon atoms, for example sorbitol or mannitol; sugars having from 5 to 12 carbon atoms, for example glucose or saccharose; amino sugars, for example glutamine; dialcohol amines, such as diethanolamine or 2-amino-1,3-propanediol.

Bacteria-Inhibiting AgentsTypical examples of bacteria-inhibiting agents are preservatives that have a specific action against gram-positive bacteria, such as 2,4,4′-trichloro-2′-hydroxydiphenyl ether, chlor-hexidine (1,6-di(4-chlorophenyl-biguanido)hexane) or TCC (3,4,4′-trichlorocarbanilide). A large number of aromatic substances and ethereal oils also have antimicrobial properties. Typical examples are the active ingredients eugenol, menthol and thymol in clove oil, mint oil and thyme oil. A natural deodorizing agent of interest is the terpene alcohol farnesol (3,7,11-trimethyl-2,6,10-dodecatrien-1-ol), which is present in lime blossom oil. Glycerol monolaurate has also proved to be a bacteriostatic agent.
