Definitions

  • the present invention belongs to the cosmetic field, and specifically relates to an improved quick breaking water-in-oil emulsion.
  • emulsions are understood as heterogeneous systems, which consist of at least two liquids, which are immiscible or have only a limited miscibility with one another and are usually referred to as phases.
  • one of the two liquids water or oil
  • the droplets pure liquids or as solutions
  • an emulsion is only of a limited stability.
  • Water-in-oil emulsions are characterized in that watery droplets are dispersed in a continuous oil phase.
  • a Water-in-oil emulsion may be abbreviated as W/O emulsion. Both expressions are used synonymously in this specification.
  • Quick-breaking means that shear forces acting upon a water-in-oil emulsion by distributing a suitable amount of the respective emulsion preparation on the skin and/or massaging the preparation in the skin, will decompose or “break” the emulsion and watery or milky droplets are released. The release of such droplets results in a refreshing and cooling effect.
  • Water-in-oil emulsions being described as “quick-breaking” .
  • Water-in-oil emulsions according to CN 104968318 A being classified as quick-breaking, contain specific emulsifiers, namely Amodimethicone Glycerocarbamat and/or Diisostearoyl Polyglyceryl-3 Dimer Dilinoleat.
  • Said emulsions are free from polyethylene glycols or derivatives of polyethylene glycols.
  • JP 5477883 B2 a water-in-oil type emulsion composition is described.
  • two different surfactants are necessary, namely a hydrophilic one and a lipophilic one, to stabilize the emulsion.
  • the powders contained are hydrophobic powders or the powders after a hydrophobization treatment.
  • Nivea Men Hydration Water Burst Serum (Mintel number 3478277) is a W/O-emulsion characterized by a “quick-breaking” upon usage.
  • the product contains the emulsifier Lauryl-PEG-9 Polymethyl siloxyethyl dimethicone. The product is available in China since September 2015.
  • the product Skin Nutrient Goat’s Milk Magic Touch produced by the company Australia Health Research &Development Group contains the emulsifier PEG/PPG-10/1 dimethicone and is a quick-breaking emulsion.
  • Water in oil emulsions with quick breaking effect provide a special application experience for the consumer.
  • watery (aqueous) or milky droplets become apparent.
  • a perfect breaking effect is difficult to achieve. If the breaking effect is occurring too slowly or only to a small extent, the consumer will not notice the effect of quick-breaking water-in-oil emulsions, namely the watery or milky droplets leading to a cooling and/or a refreshing effect.
  • the droplets are too small or too big, the visual and tactile impression is not perfect.
  • the amount of water contained in such emulsions may be increased; however this results in compositions, which are more unstable.
  • To improve the stability in general more oily components are added and the amount of water is reduced. This will lead to a worsening of the quick-breaking effect and a sensory impression of oiliness and greasiness after application of such an emulsion on the skin.
  • quick-breaking water-in-oil emulsion provided in form of “milks” or milky lotions
  • a quick-breaking effect which is not optimized, may lead to whitish or white residues on the skin after application of such a composition. Consumers do not like this and probably will not rebuy such a product.
  • the skin should feel fresh and/or refreshed without any oiliness or greasiness.
  • the composition itself shall be perceived as a light, pleasant composition.
  • the quick-breaking water-in-oil emulsions are improved significantly.

  • non-polar oils comprise branched hydrocarbons having in total 12 to 40 carbon atoms, preferably 12 to 16 carbon atoms. It is preferred, if isohexadecane and/or isododecane are contained in the preparation according to the present invention.

  • Cyclomethicones may be characterized by the following formula:
  • n is from 3 to 30.
  • cyclomethicones with n representing 4 to 6 are mainly used. These components have the property to reduce the stickiness of cosmetic preparations. They are colorless and thin fluids.
  • cyclotetrasiloxane (D4) is considered as presumably affecting fertility and being harmful for aquatic organisms. Furthermore, the degradability is slow and therefore this substance is accumulated in living organisms.

  • one or more emulsifier (s) is/are contained in general.
  • Emulsifiers help to combine two immiscible liquids (for example oil in water) in a way to result in a stable preparation, an emulsion. For that reason emulsifiers have to have an amphiphilic character, the hydrophobic part interacts with the oily or lipid phase and the hydrophilic part interacts with the aqueous phase. By stirring or homogenizing, droplets are generated, which are dispersed in the respective environment, namely aqueous droplets in a lipid environment or lipid droplets in an aqueous environment. Primarily, emulsifiers do not have a detersive, surfactant character.
  • Emulsifiers reduce the interfacial tension between the two phases and, besides reducing the interfacial work, also achieve a stabilization of the formed emulsion. They stabilize the emulsion by means of interfacial films, as well as by forming steric or electrical barriers, as a result of which the merging (coalescence) of the emulsified particles is prevented.
  • HLB values are suitable to characterize emulsifiers, said values specify the hydrophilicity of a given emulsifier.
  • the HLB value may be determined by the following formula:
  • HLB 20 ⁇ (1-M lipophile /M)
