Description

Aqueous pearl luster concentrates.

Field of the Invention

The invention relates to aqueous concentrates of pearl luster with an acid ester content special polyolcarboxylic emulsifiers and, where appropriate, polyols, to a procedure for obtaining it, to another procedure for obtaining surfactant preparations, of pearl luster, with the use of concentrates as well as the use of esters of polyolcarboxylic acids as pearl luster waxes.

State of the art

The slightly iridescent luster of pearls has exerted a special fascination on human beings for millennia. For this reason products with an attractive, valuable and generous appearance have a special interest. The first pearl luster, used in the middle ages in cosmetic products was a pearl luster paste consisting of natural fish scales. At the beginning of this century it was discovered that bismuth oxychlorides are equally capable of generating a pearl luster. For modern cosmetics, pearl luster waxes, especially of the type of glycol esters of mono and dense acids, which are used predominantly for the generation of a pearl luster in shampoos for hair and hair are significant. shower gels. A compilation related to modern formulations, with pearl luster, is found in the publication of A.Ansmann and R.Kawa in Parf. Kosm. 75 , 578 (1994).

The state of the art knows a plurality of formulations, which provide the desired pearl luster to surfactants. In this way they are known, for example, by two German patent applications DE-A1 38 43 572 and DE-A1 41 03 551 (Henkel) gloss concentrates pearlized in the form of dispersible aqueous dispersions containing from 15 to 40% by weight of pearl luster components, from 5 to 55% by weight of emulsifiers and from 0.1 up to 5 or from 15 to 40% by weight of polyols. The pearl luster waxes consist of polyalkylene glycols acylates, monoalkanolamides, linear, saturated or ketosulfones In the specification of the patent DE 19622968 A1 (Henkel) are also described mixtures consisting of 1 to 99.9% by weight of fatty products, such as, for example, alcohols fatty, fatty ketones fatty carbonates and fatty ethers, from a 0.1 to 90% by weight of emulsifiers and from 0 to 40% in Polyols weight. In the two descriptive reports of the patents European EP-B1 0 181 773 and EP-B1 0 285 389 (Procter & Gamble) compositions are proposed for shampoos, which contain surfactants, non-volatile silicones and pearl luster waxes. The object of the patent application European PE-A2 0 205 922 (Henkel) is constituted by scattered concentrates of pearl luster, which contain from 5 to 15% by weight of acylated polyglycols, from 1 to 1 6% by weight of fatty acid monoethanolamides and from 1 up to 5% by weight of non-ionic emulsifiers. According to teachings of the specification of the European patent EP-B1 0 569 843 (Hoechst) can also be obtained dispersions of pearl luster not ionic, spreadable, if prepare mixtures of 5 to 30% by weight of polyglycols acylated and from 0.1 to 20% by weight of non-surfactants ionic selected. By European patent application EP-A2 0 581 193 (Hoechst) are also known dispersible pearl luster dispersions, free of preservatives, containing acylated polyglycol ethers, betaines, surfactants anionic and glycerin. In the European patent application EP-A1 0 684 302 (Th. Goldschmidt) proposes the use of polyglycerin esters as auxiliary agents for crystallization to obtain gloss concentrates pearly

In spite of the plurality of the agents it exists in trade a permanent need for new shine waxes pearly that do not present, for example, against what happens in the case of acylated polyglycols, oxide units of ethylene and that are characterized by a bright luster against state-of-the-art products even with smaller amounts of application, which allow the concomitant use of components critics such as silicone, without being influenced negatively on the stability of the formulations at the same time that they have ester groups in order to guarantee sufficient biodegradability and that they are still easily movable especially in concentrated form and, therefore, that Be manipulable. The task of the present invention consisted, by therefore, in making new gloss concentrates available pearled with the complex requirements profile indicated.

Typical examples of fats are glycerides, as waxes include , among others, natural waxes, such as, for example, candelilla wax, carnauba wax, Japan wax, espartogras wax, cork wax, guaruma wax, rice seed oil wax, sugarcane wax, ouricury wax, Montana wax, beeswax, shellac wax, whale sperm, lanolin (wool wax), uropigal wax, ceresin or ozoquerite ( mineral wax), petrolatum, paraffin wax or microceres; Chemically modified waxes (hard waxes), such as, for example, Montana wax, sasol wax, hydrogenated Japan wax, as well as synthetic waxes such as, for example polyalkylene wax and polyethylene glycol wax.

As stabilizers, metal salts of fatty acids can be used, such as, for example, magnesium, aluminum and / or zinc stearate or ricinoleate.

Biogenic active products will be understood as, for example, tocopherol, tocopherol acetate, tocopherol palmitate, ascorbic acid, deoxyribonucleic acids, retinol, bisabolol, allantoin, phytantriol, pentenol, AHA acids, choic acid, amino acids, ceramides, pseudoceramides, essential oils , plant extracts and vitamin complexes.

Cosmetic deodorants (deodorants) oppose body odor, covering or eliminating it. Body odor is generated by the effect of skin bacteria on apocrynous sweat, degradation products of unpleasant odor. Therefore, deodorants contain active products that act as germ inhibitors, enzyme inhibitors, odor absorbers or odor masks.

Suitable germ inhibitors are basically all active products against gram positive bacteria such as, for example, 4-hydroxybenzoic acid and its salts and esters, N- (4-chlorophenyl) -N '- (3,4 -dichlorophenyl) urea, 2,4,4'-trichloro-2'-hydroxy diphenyl ether (Triclosan), 4-chloro-3,5-dimethylphenol, 2,2'-methylene-bis (6-bromo-4- chlorophenol), 3-methyl-4- (1-methyl ethyl) phenol, 2-benzyl-4-chlorophenol, 3- (4-chlorophenoxy) -1,2-propanediol, 3-iodo-2- carbamate propionylbutyl, chlorohexidine, 3,4,4'-trichlorocarbanilide (TTC), antibacterial odorizing products, thymol, thiamine essence, eugenol, carnation essence, menthol, peppermint essence, farnesol, phenoxyethanol, glycerin monolaurate (GML) , diglycerin monocaprinate (DMC), salicylic acid N-alkylamides such as for example salicylic acid n-octylamide or salicylic acid n-decylamide.

Suitable inhibitors of enzymes are, for example, esterase inhibitors. In this case, it is preferably trialkyl citrates such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, especially, triethyl citrate (Hydagen® CAT. Henkel KGaA, Düsseldorf / RFA ). The products inhibit the enzymatic activity and thus reduce the generation of odor. Other products, which are considered as esterase inhibitors are sterol sulfates or phosphates, such as, for example, sulfate or lanoesterine phosphate, cholesterol, campesterine, stigmasterine and sitosterine, dicarboxylic acids and their esters, such as, for example, glutaric acid , monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and their esters such as for example citric acid, malic acid, tartaric acid or diethyl tartrate, as well as zinc glycinate.

Suitable odor absorbers are products that absorb odor-forming compounds and can retain them widely. These reduce the partial pressure of the individual components and thus also reduce their propagation speed. In this case it is important that perfumes have to remain untouched. Odor absorbers have no activity against bacteria. These contain, for example, as a main component, a complex zinc salt of ricinolic acid or special odorizing products, widely neutral in smell, which are known to those skilled in the art as "fixatives", such as, for example, extracts of Labdanum or Styrax or certain derivatives of abietic acid. Odorizing products or scented essences act as products to cover the odor, which, in addition to their function as odor coverings, give deodorants their corresponding odor note. As perfume scents, for example, mixtures consisting of natural and synthetic odorizing products can be mentioned. Natural odorizing products are extracts of petals, stems and leaves, fruits, fruit peels, roots, wood, herbs and lawns, needles and branches as well as resins and balms. In addition, animal odorizing products such as Zibet and Castoreum come into consideration. Typical synthetic odorizing compounds are products of the type of esters, ethers, aldehydes, ketones, alcohols and hydrocarbons. Odorizing compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allylcyclohexyl propionate, stiralyl propionate and benzyl salicylate. To ethers belong, for example, benzylethyl ether, to aldehydes for example linear alkanes with 8 to 18 carbon atoms, citral, citronelal, citronelliloxyacetaldehyde, cyclamenaldehyde, hydroxycitronal, lilial and Bourgeonal, to ketones, for example, yonones and methylcerylacetone , to the alcohols anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethylalcohol and terpineol, to the hydrocarbons belong mainly terpenes and balms. However, mixtures of various odorizing products, which together generate a striking odor note, will preferably be used. Also suitable as perfuming essences are etheric essences of low volatility, which are used in most cases as flavoring components, for example sage essence, chamomile essence, carnation essence, melissa essence, mint essence, cinnamon leaf essence, linden flower essence, thread berry essence, vetiver essence, olibano essence, radish essence, labdano essence and lavender essence.
