Definitions

  • This invention relates to cosmetic and personal care formulations.
  • this invention relates to cosmetic formulations having brilliant, intense goniochromatic multi-quadrant interference color travel effect.
  • Effect pigments also known as pearlescent or nacreous pigments, are based on the use of a laminar substrate such as mica or glass flake, which has been coated with a metal oxide layer. These pigments exhibit pearl-like luster as a result of reflection and refraction of light, and depending on the thickness of the metal oxide layer, they can also exhibit interference color effects.
  • Titanium dioxide-coated mica and iron oxide-coated mica effect pigments are the effect pigments which are encountered most often on a commercial basis. Pigments in which the metal oxide has been over- coated with another material are also well known in the art.
  • the commercially available effect pigments which contain only a single coating of a high refractive index material provide only two reflecting interfaces between materials. These two material interfaces (and reflections) are therefore solely responsible for the reflectivity achieved from the platelet surface. A substantial percentage of the incident light is thus transmitted through the platelet and while this is necessary to create the nacreous appearance of the pigment, it also diminishes other desirable properties of the effect pigments such as luster, chromaticity and hiding power. To counteract this consequence, the art has either mixed the effect pigments with other pigments or added additional layers of transparent and/or selectively absorbing materials onto the effect pigment.
  • Examples of prior art describing multi-coated effect pigments include JP 7-246366, WO 98/53011 , WO 98/53012 and U.S. Pat. No. 4,434,010. All of such prior art requires that each coated layer possess an optical thickness equal to a whole number multiple of a one-quarter of the wave-length at which interference is expected. Such construction of the so-called quarter-wave stacks is a widely accepted and implemented condition in the thin-film industries. Because of this limitation, a unique layer thickness combination is essential in order to create each individual one of the interference colors of the visible spectrum.
  • the base substrate is the only dimension common to all of the compositions displaying different interference colors.
  • the goniochromatic interference color travel effect can be produced and intensified when the goniochromatic non-quarter-wave, multi-layer interference effect materials are blended with effect pigments such as combination pigments having both absorption and reflection colors. It is an aspect of this invention to provide brilliant, intense goniochromatic interference color travel effect material for use in cosmetic and personal care formulations.
  • This invention relates to cosmetic and personal care formulations.
  • this invention relates to cosmetic formulations having brilliant, intense goniochromatic interference color travel effect.
  • the formulations use non-quarter wave, multi-layer goniochromatic color travel effect pigments.
  • such pigments may be combined with multilayer effect/combination pigments to produce and intensify the color travel effect.
  • Figure 2 is a graph comparing the color travel of a cosmetic containing the inventive pigment with a cosmetic containing a commercial pigment.
  • the cosmetic and personal care formulations include a non-quarter-wave multi-layered effect pigment product composed of a transparent substrate having an odd number of layers thereon and in which at least one of the layers has an optical thickness which is different from all of the other layers causing the pigment not to be a quarter-wave stack, i.e., non-quarter wave pigment.
  • the non-quarter wave goniochromatic pigments of this invention are described in commonly assigned pending patent application Serial 60/652020 filed February 12, 2005 incorporated in its entirety herein by reference.
  • Multi-layer effects pigments are also described in commonly assigned US Patent 6,875,264 and US Patent Application Publication 2005/0166799 incorporated in their entireties herein by reference.
  • any encapsulatable smooth and transparent platelet can be used as the substrate to make the non-quarter-wave multi-layered effect pigment.
  • useable platelets include mica, whether natural or synthetic, kaolin, glass flakes, borosilicate, bismuth oxychloride, platy aluminum oxide, or any transparent platelet of the proper dimensions.
  • Pigments containing borosilicate-based substrates are pure (free from impurities), smooth (little light scattering) and with high transparency and chroma.
  • the substrate need not be totally transparent but should, preferably, have at least about 75% transmission.
  • the size of the platelet shaped substrate is not critical per se and can be adapted to the particular use.
  • the particles have major dimensions averaging about 5- 250 microns, preferably 5-100 microns, and an aspect ratio greater than about 5.
  • the specific free surface area (BET) of the substrate is, in general, from about 0.2 to 25 m 2 /g.
  • the layers encapsulating the substrate alternate between high refractive index materials and low refractive index materials.
  • the high refractive index materials can be anatase titanium dioxide, rutile titanium dioxide, iron oxide, zirconium dioxide, zinc oxide, zinc sulfide, bismuth oxychloride or the like.
  • the CRC Handbook of Chemistry and Physics, 63 rd Edition reports refractive indices for these high refractive index materials as follows.
  • the low refractive index material can be silicon dioxide, magnesium fluoride, aluminum oxide, a polymer such as polymethyl methacrylate, polystyrene, ethylene vinyl acetate, polyurea, polyurethane, polydivinyl benzene and the like.
  • the CRC handbook of Chemistry and Physics, 63 rd Edition reports refractive indices for these low refractive index materials as follows.
  • any combination of materials can be selected provided that adjacent layers differ in refractive index by at least about 0.2, and more preferably at least about 0.6.
  • the materials are transparent but may, like iron oxide, have an absorption component.
  • a layer of titanium dioxide on said transparent substrate (i) or said optional coating (ii) as used herein means that the titanium dioxide may be in direct contact with the transparent substrate or an optional coating may be present between the transparent substrate and the layer of titanium dioxide or additives may be present between the transparent substrate and the titanium dioxide layer.
  • a subsequent layer of a low refractive index material on said titanium dioxide layer as used herein means that the subsequent layer of a low refractive index material may be in direct contact with the titanium dioxide layer or additives or other layers may be present between the subsequent layer of a low refractive index material and the titanium dioxide layer.
  • an outermost layer of a high refractive index material placed on said subsequent layer (iv) or said optional coating (v) means that the outermost layer of a high refractive index material may be in direct contact with the subsequent layer or the optional coating may be present between the outermost layer of a high refractive index material and the subsequent layer or additives may be present between the outermost layer of a high refractive index material and the subsequent layer.
  • the individual layers can be applied to the substrate and to each other using techniques well known in the art. Any such technique can be utilized.
  • sol-gel techniques can be used to apply the coatings. Such techniques are well known and widely practiced for thin film deposition, and are safe, economical and amenable to a wide variety of particle shapes and sizes.
  • Chemical vapor deposition techniques which have been used in some prior art have a litany of negative aspects including safety hazards, expensive reagents and infrastructure and substrate particle size limitations.
  • Monolithic web-based multi-layer coating techniques have also been used in the prior art and suffer from the disadvantages that pigment particles are formed after the coatings are applied and therefore have discontinuities in the layers at the fracture points. The particles must also be classified according to size after the monolith is fractured, whereas here the particle size can be predetermined before the coating and can be constant.
  • Useful additives include rutile directors for titanium dioxide such as tin.
  • non-quarter-wave effect pigments Another advantage of non-quarter-wave effect pigments is that the substrate and all layers have an appreciable degree of transparency and therefore the resulting pigments can exhibit unique angle dependent reflectivity ranging from nearly totally reflecting to substantially transmitting as the viewing angle is changed.
  • Many multi-coated pigments in the prior art use metal flakes as substrates and such metal layers are not capable of transmitting light and the resulting pigment is therefore totally opaque.
  • the first layer which is adjacent the substrate can be given a fixed thickness and by varying the thickness of the other layers, it is possible to prepare all of the interference colors desired. Further, the first and second coating layers may be fixed and such coated substrates may be used to prepare multiple final products by variation of the final layer only. The number of unique layer combinations necessary to prepare all of the interference colors with the above-described invention is much less than for the prior art. The adherence to the quarter-wave optical thickness condition for the layers of the prior art compositions precludes the use of universal single or double coated precursors to three layer compositions.
  • the low refractive index material is preferably silica and while this can have other thicknesses, the silica layer preferably has a thickness of at least 100 nm, preferably in the range of about 125-500 nm, and more preferably about 150-320 nm. This maximizes the degree of angle dependent color travel, which is inherent in silica films.
  • the silica layers will have a thickness to provide a variable pathlength for light dependent on the angle of incidence of light impinging thereon, it is preferred that the low refractive index material layer have a sufficient thickness to provide at least more than 75 and, more preferably, more than 100 degrees of hue angle color travel.
  • the first layer on the substrate and the outermost layer can be the same or different, and are further preferably titanium dioxide.
  • the substrate Prior to the formation of the titanium dioxide layer, the substrate may have an optional coating thereon.
  • the optional coating may be a metal oxide such as SiO 2 or a rutile director such as tin.
  • the outermost high refractive index layer will control the interference color as a result of its thickness.
  • the substrate/first layer/subsequent layer combination thus acts as a universal base from which all interference colors can be realized by simply varying the thickness of the third layer.
  • the thickness of the first titanium dioxide layer will generally range from about 45 to 65 nm.
  • the thickness of the third layer, when it is titania, in such an arrangement generally varies from about 20 to 100 nm, and preferably about 40-100 nm. More consistent color can be achieved if the outermost titania layer is at least 40 nm.
  • the pigments of this invention have non-white hues.
  • a "non-white" hue according to this invention means the pigments of this invention will have a chromaticity (0 degrees C*) of at least 40.0 and are not a white to pearl or silvery color. In the cosmetic and personal care field, these pigments can be used in the eye area, lip area and in all external and rinse-off applications.
  • they can be used in hair sprays, face powder, leg-makeup, insect repellent lotion, mascara cake/cream, nail enamel, nail enamel remover, perfume lotion, and shampoos of all types (gel or liquid).
  • they can be used in shaving cream (concentrate for aerosol, brushless, lathering), skin glosser stick, skin makeup, hair groom, eye shadow (liquid, pomade, powder, stick, pressed or cream), eye liner, cologne stick, c perfume, cologne emollient, bubble bath, body lotion (moisturizing, cleansing, analgesic, astringent), after shave lotion, after bath milk and sunscreen lotion.
  • the non-quarter wave pigments can be used in lipsticks, lip gloss, etc.
  • the visible goniochromatic multi-quadrant interference color travel effects would be diminished by the opacity of the cosmetic and personal care products with opaque bases.
  • the strong and intense color travel effect of the goniochromatic non-quarter-wave multi-quadrant interference color travel effect pigment enable the pigments to be used in the cosmetic and personal care products with an opaque base.
  • Visible goniochromatic multi-quadrant interference color travel effect can be produced in formulations having opaque bases by using goniochromatic non-quarter-wave multi-layer multi-quadrant interference color travel borosilicate effect pigment.
  • the goniochromatic multi-quadrant interference color travel effect can be produced and intensified when the goniochromatic non-quarter-wave multi-layer multi-quadrant interference effect materials are blended with effect pigments, such as combination pigments, having both absorption and reflection colors, e.g. Durocrome® Iridescent Colors made by Engelhard Corporation, Iselin, NJ.
  • effect pigments such as combination pigments, having both absorption and reflection colors, e.g. Durocrome® Iridescent Colors made by Engelhard Corporation, Iselin, NJ.
  • the goniochromatic non-quarter-wave multi-quadrant interference color travel effect pigments may be used in a wide spectrum of cosmetic and personal care applications.
  • the goniochromatic multi-quadrant interference color travel effects can be not only seen in the transparent, translucent, and semi-opaque formulations (e.g. nail enamels, eye gels, hair gels, shampoos, lip glosses, glycerin soaps, etc.), but also in the opaque formulations (e.g. make-up foundations, creams, lotions, etc.)
  • transparent, translucent, and semi-opaque formulations e.g. nail enamels, eye gels, hair gels, shampoos, lip glosses, glycerin soaps, etc.
  • opaque formulations e.g. make-up foundations, creams, lotions, etc.
  • combination pigments Those pigments which have an absorption pigment added to an interference pigment resulting in enhanced color intensity are called combination pigments.
  • the addition of absorption pigments to interference pigments enhances reflection colors.
  • the absorption pigments have been precipitated onto the interference pigments so that they form an integral part of the platelets.
  • an enhancement of the yellow color will be produced.
  • the yellow of the Fe 2 O 3 adds to the yellow of the interference color producing a rich lustrous yellow color.
  • a colored oxide is used for the coating on mica, that color will combine with the added colorant and will modify the final absorption color. If a colorless oxide is used for the coating on mica, the absorption color will not be modified.
  • the concentration of the absorption pigments is adjusted so that the color intensity produced is of the same order of magnitude as the interference colors. If the concentration of the colorants is too great, the absorption colorant will obscure the interference color and no enhancement will take place. In order for this enhancement to take place, the colorants are added at a concentration between about 2% and 5% in the case of T ⁇ O 2 coated mica pigments, based upon the weight of titanium dioxide coated mica.
  • absorption pigment of the same color as the interference color can be added but different absorption colorants can be added to different interferences colors.
  • a red absorption pigment carmine
  • absorption colorants differ in color from the interference color, interesting color effects are produced depending on the background and the angle of viewing. Since the concentration of the colorants is quite low, when the combination pigments are displayed over a black background, the black absorbs the color of the colorant and only the reflection color of the interference is observed. This is true whether the pigments are observed at the normal angle or the grazing angle.
  • Combination pigments have been used in applications such as coating on white, grey or black substrates or incorporating them into formulations used for cosmetic applications such as eye shadow, etc. where such color changes would be desirable.
  • a third color can be seen when the known combination pigments are incorporated into a transparent film-forming medium and coated on a transparent substrate such as glass, acrylic sheet etc. This third color is different in color from both the reflection color and the color of the absorption pigment.
  • the third color is formed from the mixing of the transmission color of the interference pigment with the color of the absorption pigment.
  • Cosmetic and personal care formulations having extraordinary goniochromatic multi-quadrant interference color travel effect with visual depth and the appearance of dimensionality can be achieved when using goniochromatic non-quarter-wave, multi-layer, multi-quadrant, interference borosilicate-based effect pigments.
  • These formulations exhibit outstanding luster and interference color properties including goniochromaticity, at levels not possible if traditional single coated pearlescent effect pigments or quarter-wave stacks are used.
  • the important effect created by the formulation with goniochromatic non- quarter-wave multi-layer multi-quadrant interference color travel effect materials is superior to other based effect pigments, in particular, when borosilicate-based substrates are used.
  • Pigments of borosilicate-based substrates are pure (free from impurities), smooth (little light scattering) and have high transparency and chroma.
  • the goniochromatic non- quarter-wave multi-layer multi-quadrant interference color travel effect materials showed stronger color travel than traditional goniochromatic pigments, stronger color travel and chroma than even the mica-based goniochromatic pigments, and showed stronger the effects in opaque system, i.e. opaque lipsticks.
  • the outstanding results were further enhanced when the goniochromatic non-quarter-wave multi-layer multi- quadrant interference borosilicate-based effect pigments were combined with combination pigments.
  • L*, a*, and b* data are described in Richard S.
  • multi-quadrant interference effect material includes a calcium sodium borosilicate substrate, at least one titanium dioxide layer and at least one silica layer. The suitability of multi-quadrant interference effect materials for any particular cosmetic application has not been established, and is the responsibility of the end user.

Lesdites préparations renferment un substrat transparent, tel que le borosilicate, une couche de matière à indice de réfraction élevée sur ledit substrat et des couches alternées de matières à indice de réfraction élevé et bas sur la première couche, le nombre total des couches étant un nombre impair de trois au moins. Toutes les couches adjacentes ont un indice de réfraction qui diffère d'au moins environ 0,2 et au moins une desdites couches possède une épaisseur optique différente de toutes les autres couches. Le pigment à effet multicouche résultant n'est pas une pile de quarts d'onde. Une autre intensité de couleur, une certaine dimension et une certaine profondeur sont obtenues par combinaison de la matière à effet goniochromatique avec un pigment de combinaison qui est obtenu par mélange d'un substrat transparent, d'un pigment d'interférence et d'un colorant d'absorption.
