Description

Field of the Invention

The invention relates to anhydrous antiperspirant preparations containing long-chain C ₁₆ -C ₆₀ dialkyl carbonates and antiperspirant active ingredients.

State of the art

Antiperspirant compositions are known to the skilled worker in many forms. As an antiperspirant Active substances are usually used astringent substances, for example aluminum and / or zirconium salts. The compositions are as sprays, roll-on preparations, pens or as Creams on sale. Such formulations are described in Cosmetics: Science and Technology, "Antiperspirants and Deodorants" (ed .: M. S. Balsam and E. G. Sagarin, 1972), Vol. 2, Pp. 373-416 by S. Plechner and in Cosmetics Science and Technology Series: "Antiperspirants and Deodorants "(Ed .: Karl Laden), 2nd edition, pp. 233-258 and pp. 327-356.

In the cosmetics market, anhydrous cream and pencil Preparations by. In the area of water-free antiperspirant pens and so-called "soft solid" - Formulations find fatty alcohols, such as cetearyl, stearyl and behenyl alcohol as well Hydroxy fatty acids, for example 12-hydroxystearic acid, are frequently used as so-called Wax. Such pen preparations are the subject of US 4,822,603, for example US 4,126,679 and EP 117 070.

Anhydrous stick preparations that contain volatile silicone oils have the disadvantage that the dispersed active ingredients easily lead to visible product residues on skin and clothing. Under Pressure load during application also often leads to oiling (syneresis), which the cosmetic acceptance of these preparations by the user is reduced. Furthermore leaves the Fatty alcohol base is an unsatisfactory sensor even with optimal selection of other emollients Skin feeling and often leads to skin irritation.

The task was to develop anhydrous antiperspirant formulations with improved sensors and Develop skin tolerance, which leads to reduced residue formation ("white abrasion") on the skin and Wear clothes. Another aspect of the task was fine-grained and smoothness (structure) as well To improve the long-term stability of the formulations during storage.

Description of the invention

It has been found that long-chain C ₁₆ -C ₆₀ dialkyl carbonates significantly improve the product properties of anhydrous antiperspirant formulations.

• a) wenigstens einem Dialkylcarbonat der Formel (I),
  
  
  in der R¹ und R² für einen linearen oder verzweigten Alkyl- und/oder Alkenylrest mit 16 bis 60 Kohlenstoffatomen steht und n und m unabhängig voneinander 0 oder Zahlen von 1 bis 100 bedeuten, und
• b) wenigstens einem Antitranspirant-Wirkstoff

The present application therefore relates to anhydrous antiperspirant preparations containing

• a) at least one dialkyl carbonate of the formula (I),
  
  
  in which R ¹ and R ^{2 is} a linear or branched alkyl and / or alkenyl radical having 16 to 60 carbon atoms and n and m independently of one another are 0 or numbers from 1 to 100, and
• b) at least one antiperspirant active ingredient

For the purposes of the invention, compositions which are less than 5% by weight of water (water of crystallization not included), preferably less than 2% by weight of water and in particular contain less than 1% by weight of water. A residual amount of water can resource-related and therefore unavoidable.

The C ₁₆ -C ₆₀ dialkyl carbonates, alone or in admixture with additional wax-like substances, have a high consistency-influencing influence on a wide variety of emollients and are therefore particularly well suited for use in antiperspirant soft solid and pen formulations. In addition to the pure consistency properties, extremely homogeneous internal structures and homogeneous, smooth surface structures are achieved in the formulations according to the invention. The wax-like C ₁₆ -C ₆₀ dialkyl carbonates improve the overall sensory impression of the anhydrous antiperspirant formulation. This results in higher skin smoothness and skin softness, which leads to an improved care effect. The formation of residues on the skin and clothing ("white abrasion") is significantly reduced in the compositions according to the invention, so that the products are distinguished by an increased cosmetic acceptance by the users. Another object of the invention is the use of C ₁₆ -C ₆₀ dialkyl carbonates in antiperspirant formulations, in particular in anhydrous antiperspirant formulations and in particular for reducing the formation of residues.

These long-chain dialkyl carbonates can generally be used very advantageously for the formulation of Use stick masses, for example also in make-up sticks, in lipsticks, lip care sticks, Sticks with insect repellent agents or the like.

These are mixtures of homologs, the middle of which Degree of alkoxylation corresponds to the ratio of the amounts of ethylene oxide and / or propylene oxide and substrate with which the addition reaction is carried out. Depending on the degree of ethoxylation, they are W / O or O / W emulsifiers. C _12/18 fatty acid _monoesters and diesters of adducts of ethylene oxide with glycerol are known as refatting agents for cosmetic preparations.

According to the invention, particularly suitable and mild emulsifiers are polyol poly-12-hydroxystearates and mixtures thereof, which, for example, under the brands "Dehymuls® PGPH" (W / O emulsifier) or "Eumulgin® VL75" (mixture with Coco Glucosides in a weight ratio of 1: 1, O / W emulsifier) or Dehymuls® SBL (W / O emulsifier) sold by Cognis Deutschland GmbH become. The polyol component of these emulsifiers can be derived from substances that at least two, preferably 3 to 12 and in particular 3 to 8 hydroxyl groups and 2 to Have 12 carbon atoms.

In principle, suitable lipophilic W / O emulsifiers are emulsifiers with an HLB value of 1 to 8 summarized in numerous tables and known to the expert. Some of these Emulsifiers are described, for example, in Kirk-Othmer, "Encyclopedia of Chemical Technology", 3rd edition, 1979, volume 8, page 913. The HLB value can also be reduced for ethoxylated products calculate the following formula: HLB = (100-L): 5, where L is the weight fraction of the lipophilic groups, i.e. H. the fatty alkyl or fatty acyl groups in percent by weight in which the ethylene oxide adducts are.

Particularly advantageous from the group of W / O emulsifiers are partial esters of polyols, in particular C ₃ -C ₆ polyols, such as glyceryl monoesters, partial esters of pentaerythritol or sugar esters, e.g. B. sucrose distearate, sorbitan monoisostearate, Sorbitansesquüsostearat, sorbitan diisostearate, sorbitan triisostearate, sorbitan monooleate, sorbitan sesquioleate, sorbitan dioleate, sorbitan trioleate, Sorbitanmonoerucat, Sorbitansesquierucat, Sorbitandierucat, Sorbitantrierucat, Sorbitanmonoricinoleat, Sorbitansesquiricinoleat, Sorbitandiricinoleat, Sorbitantriricinoleat, Sorbitanmonohydroxystearat, Sorbitansesquihydroxystearat, Sorbitandihydroxystearat, Sorbitantrihydroxystearat, Sorbitanmonotartrat, Sorbitansesquitartrat, Sorbitanditartrat, Sorbitan tritartrate, sorbitan monocitrate, sorbitan sesquicitrate, sorbitan dicitrate, sorbitan tricitrate, sorbitan monomaleate, sorbitan sesquimaleate, sorbitan dimalate, sorbitan trimaleate and their technical mixtures.

This is it for example, the ethylene oxide adducts already mentioned in the introduction with a corresponding high degree of ethoxylation, e.g. B. 10-20 ethylene oxide units for O / W emulsifiers and 20-40 Ethylene oxide units for so-called solubilizers. According to the invention particularly advantageous as O / W emulsifiers are ceteareth-12 and PEG-20 stearate. Preferred solubilizers are suitable Eumulgin® HRE 40 (INCI: PEG-40 Hydrogenated Castor Oil), Eumulgin® HRE 60 (INCI: PEG-60 Hydrogenated Castor Oil), Eumulgin® L (INCI: PPG-1-PEG-9 Laurylglycolether), and Eumulgin® SML 20 (INCI: Polysorbate-20).
