Definitions

  • the present invention relates generally to cold pearlizing concentrates used to impart pearl, irridescent sheen or glow, to beauty care and personal care products such as liquid soaps and shampoos.
  • Pearlescent additives also known as pearlizing agents, are added to beauty and personal care products such as hair and skin care products to provide a pearly appearance to the products. Chemicals which are tiny (micron size) needles or platelets often exhibit this pearly appearance. Materials which exhibit this effect are ethylene glycol mono-and di ⁇ stearate, TiO 2 coated mica, bismuth oxychloride, and natural mother of pearl. Many organic materials exhibit this pearlescence provided they can be produced in an appropriate needle or platelet shape. Ethylene glycol distearate (EGDS) is the most commonly utilized pearlizing agent. Obtaining good pearlescence requires obtaining the appropriate crystallization.
  • EGDS Ethylene glycol distearate
  • Consistency in obtaining the appropriate size and type of crystal formed is difBcult especially when utilizing ethylene glycol distearate or the like.
  • the controlled formation of EGDS crystals ofthe proper size to give good pearlescence depends on two major steps of the crystallization process.
  • the first step is the solubilization by addition of EGDS to the hot (above EGDS's melting point) beauty or personal care product, for example a shampoo.
  • Good, efficient solubilization ofthe EGDS depends on being above the melting point, finely emulsifying the melted EGDS, and allowing enough mixing time for the solubilization to occur.
  • the shampoo composition for example, is varied, it is generally necessary to insure that it can solubilize the EGDS at a temperature greater than EGDS's melting point but then also precipitate it at a temperature less than the melting point. If a composition has too high a solubilizing capaciry the EGDS may not crystallize out, may require too low of an outlet temperature ( ⁇ 100°F) to crystallize or may only crystallize slowly leading to crystals that are too large. If the solubilizing capacity is too low, only part of the EGDS will be solubilized and upon cooling the unsolubilized EGDS will freeze out as large chunks.
  • the precipitation or freezeout step, composition and the cooling process are important parameters.
  • the composition should not have too high a solubilization ability as discussed. Generally this is controlled by adding water or other solubilization reducing ingredients immediately prior to freeze out.
  • Several cooling processes are known in the art. Some methods nucleate crystals in only a portion of the composition and then mix these seed crystals back into the warmer composition. A single- pass method is better for controlling crystal size since it does not require remixing crystals into the uncooled composition. Many factors, such as flow rate, temperature and time, must be monitored and controlled to achieve appropriate crystal size. The formation of crystals depends very much on the rate of cooling. An imperfect cooling will decrease the pearlescence and the heating and cooling may have to be repeated until a satisfactory pearlescence is achieved.
  • a pearlizing concentrate which can be added to beauty and personal care compositions without a need for crystallization, with its requisite heating and cooling elements, can provide significant benefits. It can be added at room temperature saving energy and equipment costs and offer a more consistent pearlescence since many of the sensitive parameters of a crystallization process have been removed.
  • Cocodiethanolamide has been used as a dispersing agent in manufacturing cold pearlizing concentrates since it is liquid at room temperature and thus does not require a melting step; however, studies have raised concern that the diethanolamine, often present as a by-product of the cocodiethanolamide production, may form potentially carcinogenic nitrosamines. Thus, the use of cocodiethanolamide in personal hair care and skin products such as cosmetics, facial soaps and shampoos has been questioned from a health standpoint. It would certainly be advantageous then, to have a safe pearlizing concentrate for use in beauty and personal care compositions such as shampoo, lipstick and conditioner products without the presence of the cocodiethanolamide as a component ofthe formulation.
  • the present invention is a novel mild cold pearlizing concentrate for use in beauty and personal care compositions such as: shampoos, conditioners, lipsticks, skin creams, lotions, bubble baths, liquid dishwashing products, liquid cleaners and the like.
  • the cold pearlizing concentrate is a unique formulation of ingredients comprising: a pearlizing agent, a nonionic surfactant, an amphoteric surfactant, a glycol emulsifier and water.
  • the cold pearlizing concentrate provides a brilliant sheen and pearlescence when inco ⁇ orated into personal care and beauty care products
  • 'fcold refers to the ability of the concentrate to be added without heating the beauty and personal care products
  • a stable, mild free flowing cold pearlizing concentrate is prepared using i) a pearlizing agent, preferably a glycol stearate, ii) a nonionic surfactant, iii) an amphoteric surfactant emulsifier and stabilizer and iv) a glycol emulsifier and v) water, to obviate the use of cocodiethanolamide and provide excellent compatibility with any ionic surfactant
  • the pearlizing agent comprises from about 5% to about 40%, preferably from about 10% to about 30% and most preferably from about 15% to about 25%, by weight based on the total weight ofthe concentrate
