Description

Hydrous antiperspirant compositions with improved residue masking

The present application relates to hydrous antiperspirant compositions having improved residue masking.

State of the art

Commercially available antiperspirant compositions, also referred to below as antiperspirants, contain as antiperspirant active ingredient at least one water-soluble astringent inorganic and organic salt of aluminum, zinc or selected aluminum-zirconium mixed salts. The antiperspirant active ingredients have no direct influence on the activity of the sweat glands, but minimize the narrowing of the discharge channels sweat secretion. The AI salts cause sweat inhibition on the treated skin surfaces by superficial blockage of the sweat gland ducts as a result of Al-mucopolysaccharide precipitation.

Antiperspirant compositions are usually applied and applied in the armpit area. Upon drying of the composition on the skin or on the clothing which has come into contact with the skin after application of the antiperspirant, the antiperspirant salt is often seen as a white residue. This also occurs in aqueous compositions in which the antiperspirant salt is initially in dissolved form. The white residues are perceived by the consumer as a very negative product feature. For masking aluminum salt residues of water-containing compositions, the prior art discloses both water-soluble constituents, in particular 1,2-propylene glycol, and oils, in particular ester oils, such as isopropyl palmitate or alkylbenzoates. Such sequestering agents wet the antiperspirant salt and do not evaporate even after application to the skin, as for example water and cyclomethicone do. As a result, the antiperspirant salt dries much slower, and the occurrence of visible residues is delayed. The masking can be further improved by selecting a masking agent whose refractive index n _D lies in the region of the refractive index n _{D of} typical antiperspirant salts or typically used aqueous solutions of antiperspirant salts, ie in the range of n _D ²⁰ = 1.4 to 1 ; 5. The disadvantage of the known water-soluble sequestering agents, such as sorbitol and highly concentrated aqueous sorbitol solutions (50 to 70% by weight of sorbitol), is in particular that they give the antiperspirant composition a sticky feel on the skin. High-masking oils have the disadvantage that they can lead to fabric staining, the use of masking oils in high-content formulations aqueous phase is limited because of the difficulty of incorporation, compatibility with the formulation and stability of the formulation. For formulations with a high proportion of aqueous phase and low proportion of oil phase, in particular Rollon formulations, the masking is carried out essentially by sequestering the aqueous phase, which leads to a particularly high tackiness of the formulation at the required high concentrations.

In the case of formulations with a high proportion of aqueous phase, there is often the problem of lacking temperature stability, especially at very low temperatures.

Furthermore, there is often the problem of poor perfume adhesion in formulations with a high proportion of aqueous phase. A good perfume adhesion is particularly important for the commercial success of an antiperspirant product, because it is equated by the consumer with the antiperspirant effect of the product. To improve the perfume adhesion of water-containing compositions, cationic surfactants are frequently used, which, however, may impair the skin compatibility of the product. The use of encapsulated perfume also extends the perfume liability, but increases the cost of raw materials.

Hydrous antiperspirant compositions are available in a variety of dosage forms, for example as a propellable gas sprayable composition, particularly as a propellable gas sprayable water-in-oil emulsion. Such compositions are usually filled in spray cans of aluminum or (more rarely) tinplate, which are protected by an interior painting against corrosion. Despite such a protective coating but it can always come to corrosion damage. Another problem with such products is that the valve clogs. A corrosion inhibiting and / or valve clogging reducing composition would therefore be desirable for these particular dosage forms.

There is therefore a continuing need for aqueous antiperspirant compositions having high residue masking, reduced visible residues, reduced tack, reduced fiber soiling, improved temperature stability, prolonged perfume adhesion, and, for sprayable compositions, reduced corrosion and reduced valve clogging.

US 7569530 discloses 1, 2-cyclohexanedimethanol as antimicrobial active ingredient. In US 7591861 cyclohexanedimethanol (not indicating the substitution positions) is disclosed as a glycolic solvent having a logP value of 0.5 to 4.0 for hair pretreatment, by which the penetration of a subsequently applied dye into the hair is improved.

The definition of a fragrance in the sense of the present application is in accordance with the expert definition as it can be found in the RÖMPP Chemie Lexikon, as of December 2007. Thereafter, a fragrance is a chemical compound with smell and / or taste that excites the hair cell receptors (adequate stimulus). The necessary physical and chemical properties are a low molecular weight of at most 300 g / mol, a high vapor pressure, minimal water and high lipid solubility and weak polarity and the presence of at least one osmophoric group in the molecule. In order to delineate volatile, low molecular weight substances which are usually and also not regarded as perfuming agents, but primarily as solvents, such as, for example, ethanol, propanol, isopropanol and acetone, odorants according to the invention, fragrances according to the invention have a molecular weight of 74 to 300 g / mol, contain at least one osmophoric group in the molecule and have a smell and / or taste, that is, they excite the receptors of the hair cells of the olfactory system.

Perfumes, perfume oils, perfume oil components or individual perfume compounds can be used as fragrances. Perfume oils or fragrances can according to the invention individual fragrance compounds, eg. As the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons. Fragrance compounds of the ester type are e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate (DMBCA), phenylethylacetate, benzylacetate, ethylmethylphenylglycinate, allyl cyclohexylpropionate, styrallyl propionate, benzyl salicylate, cyclohexyl salicylate, floramate, melusate and jasmecyclate. The ethers include, for example, benzyl ethyl ether and ambroxane, to the aldehydes, for example, the linear alkanals having 8 - 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, lilial and bourgeonal, to the ketones, for example, the ionone, alpha-iso-methylionone and methylcedryl ketone; the alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol, alpha-terpineol, beta-terpineol, gamma-terpineol, and delta-terpineol; the hydrocarbons mainly include the terpenes such as limonene and pinene.

In order to be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note", "middle note or body" Since odor perception is also largely based on the odor intensity, the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note consists for the most part of less volatile substances In the composition of perfumes, for example, volatile fragrances can be bound to certain fixatives, which prevents them from evaporating too quickly the smell impression and on whether the corresponded nde perfume is perceived as the head or middle note, nothing said. Adhesion-resistant fragrances which can be used in the context of the present invention are, for example, the essential oils such as angelica root oil, aniseed oil, arnica blossom oil, basil oil, bay oil, bergamot oil, champacilla oil, pine oil, pinecone oil, elemi oil, eucalyptus oil, fennel oil, pine oil, galbanum oil, Geranium oil, ginger grass oil, guaiac wood oil, gurdy balm oil, helical oil, ho oil, ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kanaga oil, cardamom oil, cassia oil, pine needle oil, copa ^' i ^' vabalsamöl, coriander oil, spearmint oil, caraway oil, Cumin oil, Lavender oil, Lemongrass oil, Lime oil, Tangerine oil, Melissa oil, Musk grain oil, Myrrh oil, Clove oil, Neroli oil, Niaouli oil, Olibanum oil, Orange oil, Origanum oil, Palmarosa oil, Patchouli oil, Peru balsam oil, Petitgrain oil, Pepper oil, Peppermint oil, Pimento oil, Pine oil, Rose oil, Rosemary Marine Oil, Sandalwood Oil, Celery Oil, Spik Oil, Star Aniseed Oil, Turpentine Oil, Thuja Oil, T hymian oil, verbena oil, Vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, citronella oil, lemon oil and cypress oil.
