Definitions

  • the present invention relates to a solid cosmetic product, a process for producing said product, and a product prepared by the method.
  • the present invention relates to products particularly those for use in contact with the human body.
  • the present invention relates to the increasing demand for fresh and natural cosmetics and for unpackaged cosmetics.
  • Modern cosmetic products are formulated to have a very long shelf life.
  • the shelf life of a typical product is thirty one months.
  • products before products reach a retail environment, they are shipped and then stored in warehouses, sometimes for years before sale. Products may be labelled with a ‘best used by date’ but without an indication of when they were made. Consequently many formulations are assembled with longevity more in mind than effect.
  • emulsions and creams are typically sold in containers to the end user and may be dispensed by the end user.
  • the required use of packaging is a disadvantage. From an environmental perspective, waste packaging is a significant problem, despite the availability of recycling.
  • these products are prepared many months before they are applied to the skin.
  • the present invention seeks to provide a solid cosmetic product which may be used to readily form a cream or lotion for contacting with the skin of a user.
  • a solid cosmetic composition comprising
  • a process for the production of a solid cosmetic composition comprising the steps of: i) preparing a first composition comprising
  • a cosmetic method comprising contacting the skin of a user with a cosmetic prepared from a solid cosmetic composition as described herein and water.
  • a solid product may be delivered to the end user in a form which does not require sale or transportation in packaging.
  • the user may then apply water to the surface of this product and by agitation of the water on the surface of the product may form a ‘fresh’ emulsion that may then be used as a cosmetic.
  • the emulsion may be a cream or lotion such as those known to the user.
  • the present invention provides the multiple advantages of avoidance of unnecessary packaging, avoidance of transportation of water present in a cream or lotion product and allowing for the preparation of a fresh product.
  • growth of microorganisms is inhibited. This inhibition of growth through the reduction of water allows for the product to be free from the preservatives that would otherwise be necessary to avoid spoilage of a water-containing cream or lotion.
  • a solid cosmetic composition comprising
  • a cosmetic product means that the product is not edible.
  • a non edible solid cosmetic composition comprising
  • the solid products of the present invention are compositions which can substantially sustain their physical shape when unsupported by external means, e.g. packaging etc. Thus, they are considered to be solid, solid-like, in solid form or in solid-like form at room temperature. For the avoidance of doubt the solid product must remain substantially solid at up to 30 °C.
  • solid-like it is understood that some materials are considered on a day to day basis to be solid, yet over an extremely long period of time, may alter in shape, e.g. amorphous materials such as glass etc. However, they are considered to be solid-like as, for the purpose they fulfil, they are solid.

  • the gelling agent is a hydrocolloid gelling agent.
  • the thickening agent is a hydrocolloid thickening agent.
  • hydrocolloids are a heterogeneous group of long chain polymers characterised by their property of forming viscous dispersions and/or gels when dispersed in water. Some hydrocolloids have the ability to modify the rheology of compositions comprising water. However, there are two distinct types of hydrocolloid: gelling agents (i.e. those that modify the texture and/or solidity of the composition) and thickening agents (i.e.
  • the water- thickening property is common to all hydrocolloids, whilst only a few hydrocolloids have the ability to form gels (i.e. to act as a gelling agent).
  • Gel formation is typically regarded as the phenomenon involving the association or cross-linking of the polymer chains to form a three-dimensional network that traps or immobilises the water within it to form a rigid structure that is resistant to flow. In other words, the composition becomes viscoelastic exhibiting both the characteristics of a liquid and a solid.
  • thickening of a composition merely involves the non-specific entanglement of conformationally disordered polymer chains, and is essentially a polymer-solvent interaction (see, for example, D. Saha and S. Bhattacharya, J. Food Sci. Technol., 2010, 47(6): 597-597).
  • Gels may be defined as a form of matter intermediate between solid and liquid, and which show mechanical rigidity. They comprise polymer molecules cross-linked to form a tangled and interconnected molecular network immersed in a liquid medium.
  • the word “gel” typically refers to high moisture compositions that substantially sustain their physical shape when released from their container. More specifically, gels are viscoelastic systems with a storage modulus (G’) larger than the loss modulus (G”). Though all hydrocolloids may thicken aqueous dispersions, only a comparatively few gums are understood to form gels.
  • Hydrocolloids that may act as gelling agents include modified starch, agar, carrageenan, pectin, gellan gum, alginate (when combined with calcium ions), methyl cellulose, and hydroxylpropyl methylcellulose. Hydrocolloids such as xanthan gum, guar gum, konjac gum, gum tragacanth and gum Arabic are known thickening agents, but are not generally regarded as being gelling agents.

It has been found by the present inventors that kappa-carrageenan and/or iota-carrageenan may provide for an improved gelling effect as compared with that of lambda-carrageenan.

  • gellan gum is a straight chain polymer that comprises repeating units of glucose, rhamnose and glucuronic acids.
  • “High acyl” gellan gum has two acyl substituents, acetate and glycerate, that are located on the glucose residues. On average, there is one glycerate per repeat unit and one acetate every two repeat units when both are located on the same glucose residue. Deacylated (or “low acyl”) gellan gum has these acyl groups removed during processing.

Therefore, as used herein, the term “gelling agent” does not encompass hydrocolloids such as xanthan gum, guar gum, konjac gum, gum tragacanth and gum Arabic.
