Definitions
- the present invention relates to a method for using personal care compositions that improve appearance and feel of keratinous surfaces. More specifically, the present invention relates to a method of using rinsable personal care compositions that provide excellent skin radiance, skin moisturization and conditioning.
- Personal care compositions are well known and widely used. These compositions have long been employed to cleanse and moisturize skin, deliver actives, hide imperfections and to reduce the oiliness/shine associated with sebum. Personal care compositions have also been used to alter the color and appearance of skin.
- interference pigments have been used for cosmetic applications. Mica, coated with titanium dioxide has been used to yield a pigment with a silvery, pearl-like effect. See, e.g. US 3,087,829 and US 3,123,490. Later teachings disclosed the use of thin film optics that resulted in pigments with brilliant luster and a broad range of interference colors and multicolour effect. See, e.g. US 6,132,873 and US 4,323,544.
- Interference pigments have been developed for color cosmetics and skin care to provide luster and color effect. See, e.g. JP11193215, WO992400 and WO200174979.
- the surfaces of interference pigment are hydrophilic, they will remain in any aqueous phase present. As a result, they are do not associate with any oil phase present in a composition. This is often a desirable property when even dispersion of the pigments is desired to give the product a nacreous appearance.
- compositions and disclosures of the prior art provide useful advances in the art of personal care compositions, there remains the need for improved rinse off compositions and a method of using these compositions that deliver immediate improvements in appearance and skin feel that will effectively deposit on all parts of the body.
- compositions also need to be non- greasy and easy to apply. Therefore, it is desirable to provide a method of use of a topical rinse off composition comprising a select level and blend of shiny particles that provide a unique level of light reflectance and color shift to increase the radiance across all skin types. Furthermore, it is desirable to provide a method of using a personal care composition comprising shiny particles to maximize sheen and luster on the skin. It is further desirable to provide a method of use that delivers the above skin conditioning and appearance benefits via an in-the-shower or in-the-bath lotion. Unfortunately, in the shower/bath, moisturizers are often readily rinsed from the skin. This is particularly true when surfactant is present.
- compositions of the present invention can comprise, consist essentially of, or consist of, the essential as well as optional ingredients and components described herein.
- “consisting essentially of” means that the composition or component may include additional ingredients, but only if the additional ingredients do not materially alter the basic and novel characteristics of the claimed compositions or methods.
- interference pigment means a pigment with pearl gloss prepared by coating the surface of a particle substrate material (generally platelet in shape) with a thin film.
- the thin film being a transparent or semitransparent metal oxide having a high reflective index.
- the higher refractive index material shows a pearl gloss resulting from mutual interfering action between reflection and incident light from the platelet substrate/coating layer interface and reflection of incident light from the surface of the coating layer.
- rinsable composition means a composition designed to be rinsed off by a liquid such as water. After the composition is rinsed off, pigments are deposited on the skin and the skin radiance is realized.
- safe and effective amount means an amount of a compound, component, or composition sufficient to significantly induce a positive benefit, preferably a positive skin appearance or feel benefit, including independently the benefits disclosed herein, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound medical judgment.
- specular reflection refers to the phenomena where an incident beam of light is reflected at the equal and opposite angle to the angle of incidence.
- topical application means to apply or spread the compositions of the present invention onto the surface of the skin.
- compositions of the invention are useful for providing an essentially immediate (i.e., acute) visual improvement in skin appearance and radiance following rinse off of the composition from the keratinous surface. Without intending to be limited by theory, it is believed that this acute skin appearance improvement results at least in part from therapeutic coverage or masking of skin imperfections by the hydrophobically modified shiny particles.
- the compositions provide the visual benefits without imparting an unacceptable skin appearance such as skin whitening.

- the dispersed oil phase preferably comprises at least about 1 weight percent, more preferably at least about 5 weight percent, even more preferably at least about 7 weight percent, and still more preferably at least 10% of the composition.
- the shear index is a measure of how shear thinning the materials are as described in the Lipid Rheology method described herein. It is preferred that the skin compatible oil be shear thinning either by virtue of its composition or the structurants that may be added. Preferably, the shear index of the dispersed oil phase will preferably be less than 0.9, more preferably less than 0.75, even more preferably less than 0.6, even more preferably less than 0.45, and still more preferably less than 0.3.
- Skin Compatible Oils are a measure of how shear thinning the materials are as described in the Lipid Rheology method described herein.

- a second class of interference pigment is based on cholesteric liquid crystal, e.g. HELICONE ® HC supplied by KOBO products.
- HELICONE ® HC is composed of transparent platelets of polyacrylates with a helical superstructure. As part of this structure, cigar-shaped liquid crystal molecules are fixed into layers of parallel rows. Each layer has a slightly different molecular orientation and the distance between two layers with the same molecular orientation defines as the "pitch", which determines the color.

- the additional components useful herein can be categorized by the benefit they provide or by their postulated mode of action. However, it is to be understood that the additional components useful herein can in some instances provide more than one benefit or operate via more than one mode of action. Therefore, classifications herein are made for the sake of convenience and are not intended to limit the active to that particular application or applications listed. Structurants
- the present invention may optionally comprise an oil structurant.
- the structurant can provide the dispersed phase with the correct rheological properties. This can aid in providing effective deposition and retention to the skin, the structured oil or oil phase should have a viscosity in the range from 100 to about 200,000 poise measured at 1 Sec-1, preferably from 200 to about 100,000 poise, and most preferably, from 200 to about 50,000 poise as determined using the lipid rheology method described herein.
- the amount of structurant required to produce this viscosity will vary depending on the oil and the structurant, but in general, the structurant will preferably be at most 75% of the dispersed oil phase, more preferably at most 50%, and most preferably at most 35% of the dispersed oil phase.
- the structurant can be either an organic or inorganic structurant.

- Structurants meeting the above requirements with the selected skin compatible oil can form 3- dimensional network to build up the viscosity of the selected oils. It has been found that such structured oil phases, i.e., built with the 3-dimensional network, are extremely desirable for use as wet-skin treatment compositions used in bathing. These structured oils can deposit and be retained very effectively on wet skin and retained after rinsing and drying to provide long-lasting after wash skin benefit without causing a too oily/greasy wet and dry feel. It is believed that the highly desirable in-use and after-use properties of such structured oils are due to their shear thinning rheological properties and the weak structure of the network.
- the 3 -dimensional network structured oil Due to its high low-shear viscosity, the 3 -dimensional network structured oil can stick and retain well on the skin during application of the skin conditioner. After being deposited on the skin, the network yields easily during rubbing due to the weak structuring of the crystal network and its lower high-shear viscosity.

- Lipid rheology is measured on a TA Instruments AR2000 stress-controlled rheometer with a Peltier temperature controlled sample stage or an equivalent.
- a parallel plate geometry is used with a 40mm plate and a 1mm gap.
- the lower plate is heated to 85°C and the melted lipid and structurant (if present) is added onto the lower plate and allowed to equilibrate.
- the upper plate is then lowered to the 1mm gap while ensuring the lipid fills the gap fully, [spinning the top plate and adding more lipid to promote wicking], and the sample is cooled quickly to 25 °C and equilibrated at 25°C for 5 minutes.
- the viscosity at 1 sec-1 is then calculated using the calculated values of K and n from the fitted Pigment Deposition Tape Strip Method
- the Pigment Deposition Tape Strip Method can be used to semi-quantitatively determine deposition of shiny particles onto keratinous surfaces.
- the method employs the use of a tape strip for removing particles from skin and imaging these particles for a quantitation of deposited particles.
- the first step is to weigh lg of pigment that is the same as those in the product being tested in a vial.
- 9g melted petrolatum is added and mixed well with a spatula.
- Scotch Tape Take approximately 1" of Scotch Tape and apply to site #1. Rub over the top of the applied tape to pick up product below. Remove the tape and reapply same tape to very same previously stripped area, so as to pull product from area twice on the same tape. Then secure this stripping tape to a clean microscope slide, product side up, marking the slide as "1 ⁇ g/cm 2 ". Repeat the application of Scotch Tape method described previously for sites #2 through #6 (in that order), marking each slide appropriately.
- Polymeric stabilizer phase is formed using the ratio of stabilizer to water that will be found in the particular formulation of interest. For example, if the formulation contains 3 parts stabilizing polymer and 72 parts water, the ratio will be 1:24. The polymer is hydrated in the water phase at the appropriate ratio. The method of hydration will vary depending upon the polymer type, and may require high shear, heating, and/or neutralization. In any event, the polymer should be properly hydrated according to manufacturer's instructions. Once the polymer is fully hydrated, the system is allowed to sit at room temperature for at least 24 hours.
- Foam that collects on the top of the graduated cylinder but does not drain is also incorporated in the measurement if the foam on the top is in its own continuous layer, by adding the ml of foam collected there using a ruler to measure thickness of the layer, to the ml of foam measured up from the base.
- the maximum foam height is 1,000 ml (even if the total foam height, exceeds the 1,000 ml mark on the graduated cylinder).
- a second rotation sequence is commenced which is identical in speed and duration to the first rotation sequence.
- the second lather volume is recorded in the same manner as the first, after the same 30 seconds of drainage time.
- a third sequence is completed and the third lather volume is measured in the same manner, with the same pause between each for drainage and taking the measurement.
- the composition described above can be prepared by conventional formulation and mixing techniques.
- Prepare Phase 1 by first adding citric acid into the ammonium laureth-3 sulfate. Once the citric acid is full dissolved, add the sodium lauroamphoacetate. Heat the mixture to 190-195F. Incorporate the trihydroxystearin fully and then add preservatives. Continue to mix as petrolatum is added.
- Premix 2 by adding petrolatum into a separate mixing vessel. Heat the vessel to 190°F. Add SAT-Timiron Splendid Red and allow to mix well. Then add Premix 2 to Phase 2. Then add perfume. Keep agitation until a homogenous solution forms.
- the personal care composition of Example 19-25 can be prepared by conventional formulation and mixing techniques.
