Definitions
- the present invention relates to a cosmetic preparation in the form of water-in-oil emulsions containing spherical silica particles coated with titanium dioxide and iron oxides and one or more W / O emulsifiers.
- agents are used, for example, stimulate the activity of skin cells, but also increasingly used UV filters that block especially responsible for skin aging UVA rays. All these ingredients pose a great challenge for a pleasant sensory, since they remain on the skin as a film after evaporation of the volatiles of the formulation and sensory perceived by the consumer there. The sensible residues are often described negatively and prevent the feeling that the product is completely "absorbed" in the skin.
- viscosity refers to the property of a liquid to oppose resistance (toughness, internal friction) to the mutual laminar displacement of two adjacent layers.
- ⁇ ⁇ / ⁇ as the ratio of the shear stress to the velocity gradient perpendicular to the flow direction
- ⁇ at given temperature is a material constant with the SI unit pascal second (Pa-s).
- the quotient ⁇ ⁇ / ⁇ from the dynamic viscosity ⁇ and the density p ("rho") of the liquid is called the kinematic viscosity v ("ny”) and is given in the SI unit m 2 / s.
- tackiness of an ointment or ointment base or the like is understood to mean their property of drawing threads of different lengths when parting off; Accordingly, one differentiates between short and long-lasting substances.
- Falling body viscometry is only suitable for studying Newtonian fluids and gases. It is based on the Stokes law, according to which for the falling of a ball by a liquid flowing around it, the dynamic viscosity ⁇ from
- Silicone-based emulsifiers almost exclusively contain PEG- and PPG-containing groups as a hydrophilic component. Typical representatives are Cetyl PEG / PPG-10/1 Dimethicone (Abil EM 90, 180) from Evonik or PEG-10 Dimethicone (ES-5612 Formulation Aid) from Dow Corning. These examples are successful and long-established W / O emulsifiers in the market.
- PEG-free silicone emulsifiers is limited; For example, KF-6100, KF-6104, KF-6105 or KSG-710, KSG-810, KSG-820, KSG-830 or KSG-840 from Shin Etsu or Abil EM 120 from Evonik can be found here.
- pigments are known to have a "soft-focus effect.” However, it is problematical that such pigments, like many solids, can often be incorporated into cosmetic or dermatological preparations in a stable manner only by formulatorial manipulation.
- W / O emulsifiers from the group Abil EM 90, Abil EM 180 (cetyl PEG / PPG-10/1 dimethicone), Abil EM 120 (bis (glyceryl / lauryl) glyceryl lauryl dimethicone (and) Caprylic / Capric Triglycerides) from Evonik and ES-5600 (Cetyl Diglyceryl Tris (trimethylsiloxy) silylethyl dimethicone) from Dow Corning,
- the proportion of the oil phase of the preparations according to the invention in the range from 3 to 60% by weight, based on the total weight of the preparations.
- Particularly advantageous spherical silica particles coated with titanium dioxide and iron oxides are "soft focus pigments" derived from spherical silica particles coated with titanium dioxide and iron oxides, such as, for example, “RonaFlair® Flawless” from Merck available.
- W / O emulsifiers to be used particularly advantageously for the purposes of the present invention is the bis (glyceryl / lauryl) glyceryl lauryl dimethicone (and) caprylic / capric triglyceride, which has been obtained from the company Evonik (formerly Th. Goldschmidt AG) the product name ABIL® EM 120 is sold.
- the oil phase can be selected, in some cases, advantageously from the group of branched and unbranched hydrocarbons and waxes, silicone oils, dialkyl ethers, the group of saturated or unsaturated, branched or unbranched alcohols, and fatty acid triglycerides, in particular triglycerol esters of saturated and / or unsaturated . branched and / or unbranched alkanecarboxylic acids of a chain length of 8 to 24, in particular 12 to 18 carbon atoms.
- the fatty acid triglycerides can be selected, for example, advantageously from the group of synthetic, semi-synthetic and natural oils, for.
- B. Caprylic Capric triglyceride, olive oil, coconut oil, rapeseed oil, palm kernel oil, sunflower oil, soybean oil, almond oil and the like.
- hydrocarbons paraffin oil, squalane, hydrogenated polyisobutene, isohexadecan, isododecane; Ci5-i9Alkan or polydecene advantageous to use in the context of the present invention.
- vitamin E and / or its derivatives represent the antioxidant (s)
- Advantageous UV filter substances in the context of the present invention are also so-called broadband filters, d. H. Filter substances that absorb both UV-A and UV-B radiation.
- Diethylhexylbutylamidotriazone (INCI: diethylhexylbutamidotriazone), which is available under the trade name UVASORB HEB from Sigma 3V; 4,4 ', 4 "- (1,3,5-triazine-2,4,6-triyltriimino) tris-benzoic acid tris (2-ethylhexyl ester), also: 2 ! 4 ! 6-tris [anilino - (p-carbo-2'-ethyl-1'-hexyloxy)] - 1 ! 3,5-triazine (INCI: ethylhexyl triazone), which is marketed by BASF Aktiengesellschaft under the trade name U-VINUL® T 150 ,
- An advantageous broadband filter in the context of the present invention is also the 2,2'-methyl-bis (6- (2H-benzotriazol-2-yl) -4- (1,1,3,3-tetramethylbutyl) phenol ), which is available under the trade name Tinosorb® M from CIBA-Chemikalien GmbH.
- Usual colorants which are suitable for use as cosmetic or dermatological compositions in the context of the present invention are lipophilic dyes (eg Sudan Red, DB & C Red 17, DB & C Green 6, ⁇ -Carotene, Sudan Brown, DB & C Yellow 1 1, DB & C Violet 2, DB & C Orange 5 or Annatto), hydrophilic dyes, (eg beetroot juice or methylene blue) pigments, pearlescent pigments and blends of such colorants.
- lipophilic dyes eg Sudan Red, DB & C Red 17, DB & C Green 6, ⁇ -Carotene, Sudan Brown, DB & C Yellow 1 1, DB & C Violet 2, DB & C Orange 5 or Annatto
- hydrophilic dyes eg beetroot juice or methylene blue
- the pigments can also be used advantageously in the form of commercially available oily or aqueous predispersions.
- dispersants and / or solubilizers can be added to these predispersions.
- both the W / Si emulsifier and the W / O emulsifier are added to the oil phase.
- the components of the oil phase are blended together with a Blattrüher about five minutes at 400 U / min.
- the sodium chloride is dissolved in the water phase.
- the water phase is slowly added with stirring to the oil phase and then thoroughly mixed with a high-speed mixer (eg a magic stick ESGE).
- the stability was visually evaluated after 7 days, 14 days, 21 days (T) and 1 month (M).
