Description

[0181] FIG. 1 shows a container (B) which is advantageous in accordance with the invention and which has [0182] a tubular body (K), [0183] at the top end of which a dispenser head (SK) is mounted, [0184] which is bounded at the bottom by a movable drawing plunger (SCH), and [0185] a dispenser head (SK);
in FIG. 1a, the container (B) being shown separated into body (K) and dispenser head (SK) (in this case provided with an additional closure cap, not shown in any more detail).

[0186] FIG. 1a shows a dispenser head (SK)which comprises [0187] an external actuating element (BE) having a dispensing aperture (SPO) which is closed by a nonreturn valve (RV), [0188] a base unit (BO) lying on the tubular body (K) and having an opening (0) to the tubular body, and also [0189] a flexible internal substantially cylindrically shaped hollow body (H) having bellows-like walls (Wh).

[0190] FIG. 1b shows a perspective view of one embodiment of the flexible inner substantially cylindrical shaped hollow body (H) [0191] having bellows-like walls (Wh), [0192] where the bottom end face (Su) and its opening (Ou) are visible.

and where the hollow body (H) is designed such that the bottom opening (Ou) at the bottom end face (Su) comprises a means (V) which cuts up the substance stream from the interior of the tubular body (K) into the hollow body into a plurality of substreams.

[0196] FIG. 1d shows a device (V) which is intended for cutting up the substance stream from the interior of the tubular body (K) (not shown here) into the hollow body (H) (not shown here) into three substreams by means of three two passage openings (Du).

[0197] The cosmetic and dermatological preprations in accordance with the invention may comprise cosmetic auxiliaries of the kind customarily used in such preparations, examples being preservatives, preserving aids, bactericides, fragrances, substances for preventing foaming, dyes, pigments which have a coloring effect, thickeners, moisturizing and/or humectant substances, fillers which improve the feel on the skin, fats, oils, waxes, or other customary constituents of a cosmetic or dermatological formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents, or silicone derivatives.

[0198] Advantageous preservatives for the purposes of the present invention are, for example, formaldehyde donors (such as, for example, DMDM hydantoin, which is available for example under the trade name Glydant from Lonza), iodopropyl butylcarbamates (e.g., those available under the trade names Glycacil-L, Glycacil-S from Lonza and/or Dekaben LMB from Jan Dekker), parabens (i.e., alkyl esters of p-hydroxybenzoic acid, such as methyl, ethyl, propyl and/or butyl paraben), phenoxyethanol, ethanol, benzoic acid, and so on. The preservative system in accordance with the invention customarily further comprises, advantageously, preserving aids as well, such as, for example octoxyglycerol, glycine soya etc.

[0199] Particularly advantageous preparations are obtained, moreover, if antioxidants are used as adjuvants or active ingredients. In accordance with the invention the preparations advantageously comprise one or more antioxidants. Antioxidants that are favorable, but whose use is nevertheless optional, may comprise any antioxidants customary or suitable for cosmetic and/or dermatological applications.

[0200] With particular advantage for the purposes of the present invention it is possible to use water-soluble antioxidants, such as, for example, vitamins, e.g., ascorbic acid and derivatives thereof, and also D-biotin, natural and/or synthetic isoflavonoids, alpha-glucosylrutin, panthenol, aloe vera, honokiol, and magnolol.

[0201] The amount of the antioxidants (one or more compounds) in the preparations is preferably 0.001 to 30 wt %, more preferably 0.05 to 20 wt %, more particularly 0.1 to 10 wt %, based on the total weight of the preparation.

[0202] It is especially advantageous if the cosmetic preparations in accordance with the present invention comprise active cosmetic or dermatological ingredients, with preferred active ingredients being antioxidants, which are able to protect the skin from oxidative stress.

[0203] Advantageous further active ingredients are natural active ingredients and/or derivatives thereof, such as phytoene, carnitine, carnosine, creatine, N-acetylhydroxyproline, taurine and/or -alanine, for example.

[0204] The external aqueous gel phase of the preparations of the invention may advantageously comprise customary cosmetic auxiliaries, such as, for example, alcohols, especially those of low C number, preferably ethanol and/or isopropanol, diols or polyols of low C number, and also their ethers, preferably propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl or monobutyl ether, propylene glycol monomethyl, monoethyl or monobutyl ether, diethylene glycol monomethyl or monoethyl ether, and analogous products, polymers, foam stabilizers, electrolytes, and also, in particular, one or more thickeners, which may be selected advantageously from the group of silicon dioxide, aluminum silicates, polysaccharides and/or derivatives thereof, e.g., hyaluronic acid, xanthan gum, hydroxypropylmethylcellulose, particularly advantageously from the group of the polyacrylates, preferably a polyacrylate from the group known as carbopols, examples being carbopols of types 980, 981, 1382, 2984, 5984, in each case individually or in combination. Moisturizers as well may be used with preference.

[0205] Moisturizers are compounds or compositions which endow cosmetic or dermatological preparations with the capacity, following application or distribution on the skin surface, to reduce the loss of moisture by the stratum corneum (also called transepidermal water loss (TEWL)) and/or to influence positively the hydration of the stratum corneum.

[0206] Advantageous moisturizers for the purposes of the present invention are, for example, glycerol, lactic acid and/or lactates, especially sodium lactate, butylene glycol, propylene glycol, biosaccharide gum-1, Glycine soja, ethylhexyloxyglycerol, pyrrolidonecarboxylic acid, and urea. It is especially advantageous, furthermore, to use polymeric moisturizers from the group of the water-soluble and/or water-swellable and/or water-gellable polysaccharides. Especially advantageous are, for example, hyaluronic acid, chitosan and/or a fucose-rich polysaccharide which is recorded in Chemical Abstracts under the registry number 178463-23-5 and is available for example under the name Fucogel 1000 from SOLABIA S.A.

[0207] The cosmetic or dermatological preparations of the invention may further advantageouslyalthough not mandatorilycomprise fillers, which, for example, further improve the sensory and cosmetic qualities of the formulations and, for example, evoke or reinforce a silky or satiny feel on the skin. Advantageous fillers for the purposes of the present invention are starch and starch derivatives (such as, for example, tapioca starch, distarch phosphate, aluminum and/or sodium starch octenylsuccinate, and the like), pigments which have neither primarily UV filter activity nor coloring activity (such as, for example, boron nitride, etc.) and/or Aerosils (CAS No. 7631-86-9).

[0208] The examples which follow are intended to illustrate the present invention without limiting it. The numerical values in the examples denote weight percentages, based on the total weight of the respective preparations.
