Definitions
- the invention relates to electrolyte-stable emulsions based on C16 / C18 fatty acid mixtures.
- a cosmetic emulsion comprising one or more C14 to C22 fatty acids as emulsifier A and one or more lipophilic emulsifiers having an HLB ⁇ 7 as coemulsifiers B, characterized in that the mass ratio of emulsifiers A and coemulsifiers B of Is 3: 1 to 15: 1 and the total concentration of emulsifier A is at least 5% by weight and that one or more electrolytes are contained in the aqueous phase, wherein the ionic strength of the aqueous phase in which the electrolyte or electrolytes are dissolved, at least 0.002 mol / l, where the ionic strength refers to positive and negative charges.
- the use of a co-emulsifier can reduce the amount of fatty acids necessary to produce the dull skin sensation.
- inventive preparations therefore have, in addition to a proportion of C14 to C22 fatty acids or mixtures thereof (emulsifier A), a Coemulgator B, through which the
- Fatty acid concentrations - compared to the known preparations with dull skin feeling - can be lowered to harmless levels.
- the inventive preparations are particularly suitable for topical application to sensitive skin.
- Sensitive skin in the context of the invention means a combination of various symptoms, such as hyperreactive and intolerant skin, but also atopic skin. These skin conditions are often referred to as "allergic" skin, although an allergic disease can lead to symptoms of sensitive skin, the phenomenon "sensitive skin” is not limited to allergy sufferers.
- the topical application of the inventive preparations does not constitute a therapy, but is purely cosmetic and helps the affected person to improve the appearance of the skin.
- the inventive preparation is almost free from irritation, so that no additional skin sensitivity enhancing reactions occur. This is achieved by the low concentration of emulsifier A compared to the prior art.
- the problem of "sensitive skin” affects a growing number of adults and children.
- mixtures of C16 / C18 fatty acids are advantageously used, the ratio of C16 to C18 in the range of 1:10 to 10: 1, particularly preferably in the range of 1: 1 or 45:55.
- Particularly advantageous is the use of Pristerene 4960 from Uniquema, Bergazid C1618-1 BDF from Berg & Schmidt and / or Omyacid 48 (cosmed grade) from Omya Peralta.
- emulsifier A a mixture of palmitic acid and stearic acid (45:55) as fatty acid.
- Suitable coemulsifiers B are all lipophilic emulsifiers such as fatty acid esters, fatty alcohols having an HLB less than or equal to 7.0, glycerol monostearate and / or sorbitan monostearate and / or cetyl alcohol and / or stearyl alcohol being particularly advantageous.
- liquid lipids such as ester oils, triglycerides, silicone oils, especially non-polar lipids such as mineral oils,
- Liquid sunscreen filters such as, for example, ethylhexyl methoxycinnamate, ethylhexyl salicylate, octocrylene,
- Macadamia oil such as Macadamia oil, almond oil, avocado oil, jojoba oil,
- the proportion of C14 to C22 fatty acids is selected in the range of 3 to 13 wt .-%, wherein the co-emulsifier should not exceed a content of 3 wt .-%.
- emulsifier A and co-emulsifier B are in a ratio of 3: 1 to 15: 1 to each other, particularly advantageous is a ratio of 4: 1 to 10: 1 with an optimum in the range of 4: 1 to 7 : 1 is received.
- the total content of emulsifiers A must be at least 5% by weight of the preparation, but should not exceed 15% by weight in order to ensure good compatibility.
- electrolytes it is advantageous to enrich the preparation with electrolytes, as this permanently enhances the dull skin feeling. Due to their polar properties, electrolytes preferentially stay in the water phase of the preparation.
- inventive emulsions show sufficient stability for cosmetic applications up to a content of 5% by weight of electrolytes.
- Inorganic salts especially alkaline earth and alkali salts containing a chloride, especially NaCl, KCl, NH 4 Cl, ZnCl 2 , MgCl and MgSO 4 sulfate
- alkaline earth and alkali salts containing a chloride especially NaCl, KCl, NH 4 Cl, ZnCl 2 , MgCl and MgSO 4 sulfate
- Water Soluble Light Filter Water soluble sunscreen filters are understood to mean all UV absorbing ingredients present in the aqueous phase
- Salts of naturally occurring acids in the skin eg the energy metabolism such as sodium liponate, sodium citrate, ammonium lactate, sodium lactate, sodium bicarbonate, sodium citrate) or weak carboxylic acids (eg sodium propionate)
- energy metabolism such as sodium liponate, sodium citrate, ammonium lactate, sodium lactate, sodium bicarbonate, sodium citrate
- weak carboxylic acids eg sodium propionate
- Amino acids in particular glycine, alanine and / or asparagine
- the preparations show, from a content of 0.002 mol / l of electrolytes (based on the aqueous phase) an increasingly dull skin feeling, the maximum of "stumpiness" between 0.07 and 0.35 mol / l is achieved.
- inventive preparations can be upgraded in particular by the incorporation of water-soluble sunscreen filters.
- Water-soluble sunscreen filters are to be understood as meaning all UV-absorbing ingredients which are present in the aqueous phase, hydrophobic particulate sunscreen filters, such as metal oxides, being understood here as well.
- advantageous water-soluble light protection filters which are also electrolytes, are phenylbenzimidazole sulfonic acid, in particular the EUSOLEX 232® and NEO HELIOPAN type Hydro® from Symrise offered by Merck, and disodium phenyl dibenzimidazole tetrasulfonate, in particular NEO HELOPAN AP® from Symrise ,
- the particulate sunscreen filter With a matting effect, which is excellent with the dull skin feel.
- Particularly suitable for this purpose are titanium dioxide and / or zinc oxide, where the surface of the oxides can be modified inorganically or organically.
- the preparations may contain other substances that enhance the matting effect.
- fatty alcohols fatty acid esters, water and oil insoluble solid particles, such as.
- organic and inorganic polymers starches, starches, modified starch, mica, TaIc, silica, silicates, phyllosilicates, nylon, PMMA, methyl methacrylates, methacrylates, polyurethanes, polyethylenes, polytetrafluoroethylene, polyacrylklareester- Polymers and / or their cross- or copolymers.
