Technical field

The present invention relates to granules of pigments is handled improving their hydrophobic methods, and the personal care composition that contains the granules of pigments of the granules of pigments of described modification or coating.

Background technology

Insoluble pigment material or granules of pigments, for example coloured pigment (colorful pigments), sun-screening agent, talcum etc. are used for makeup at large and other is industrial as paint industry (paint), coatings industry (coatings) and plastics industry, to improve multiple use.Suitable pigment or granules of pigments can be given color, opacity or specific visual effect such as pearly-lustre to the consumer's goods and industrial goods widely, or other quality such as bulk property (bulk), flowing property (free) and oil absorptiveness (oil absorbency).These pigment are insoluble in water-bearing media or the organic medium usually.Below the present invention will be described, in using the present invention as for personal care articles (personal care product), what it should be understood that is, novel material provided by the present invention, method and composition of matter also are useful in other industry, can use the pigment of described modification in these other industry, this is conspicuous from the disclosed content of the application for a person skilled in the art.

The granules of pigments that the present invention pays close attention to is particle in small, broken bits (well divided particles), and it is intended to be scattered in the finished product equably.Particle size (defined particle size) that limits and dispersion uniformly are that the finished product quality and pigment are effectively utilized contributive ideal behavior.In the finished product, it is long-pending that trickleer granules of pigments exposes the more particles material surface, thereby more effectively give the finished product with described particulate color or other character.Bigger particle presents better lining ability (coveragepower), perhaps, in the situation of effect pigment (effect pigment), presents more gloss and brilliance (sparkle).Have a good storage life and do not have the consistent commodity of decolouring (discoloration), sedimentation or other defective for providing, particle liquid or even the pigment vehicle in homodisperse be ideal or or even necessary.

To granules of pigments, pigment especially in small, broken bits numerous difficulties may occur when carrying out homodisperse.When unprocessed, many pigment, for example metal oxide such as ferric oxide, titanium dioxide and zinc oxide, has significant surface reaction, described surface reaction can be owing to chemical reactivity (covalent reaction or ionic reaction), perhaps owing to the absorption of more physical phenomenons such as surface charge or gather.Surface reaction can hinder the homogeneity of described powder initial dispersion, perhaps can the permanent stability of the finished product be had a negative impact.Granules of pigments may tend to covalently or electrochemically combine with other composition in the preparation, perhaps tends to agglomeration, and agglomeration is meant with the form of agglomerate (agglomerations) or agglomerate (clumps) bonded to one another.The result causes the finished product difference or unacceptable, and perhaps limited storage life of causing owing to color or other character of product, and product agglomeration, product is poor, have grittiness or rough sense, and the product sedimentation etc.

In addition, the surface tension of undressed mineral dye and wetting ability make to be bonded to and become complicated in the lipophilicity system, and strong oil absorbency has a negative impact to viscosity simultaneously.

At last, during bulk materials (bulk material) was handled, undressed granules of pigments was low-density light granules especially, caused serious airborne dust problem (dusting problems).

In order to overcome these problems, common for a long time way is that pigment is carried out surface treatment, makes pigment have processing, processibility and the performance in the finished product of hydrophobicity and raising pigment.Typical coating (coating) effect is: reduce granules of pigments surfactivity, repel water or other water-bearing media, suppress nodulizing, reduce oil absorbency and improve water-bearing media that powder particle uses in when the preparation the finished product or the dispersiveness in the oily medium.Gratifying coating should fully and be similar to and cover each particle equably.

For this reason, many hydrophobic coatings and processing can commercially obtain, and in the literature, especially propose in patent documentation.With regard to a kind of pigment or a few pigment, these hydrophobic coatings and to handle for some purposes be effectively, but just known to the applicant, not having a kind of processing is effective to FR granules of pigments.

Insoluble granules of pigments comprises that material that many difference are very big such as metal oxide, metal silicate, other inorganic salt, pigment swelling agent (extender) or filler (filler) are as talcum and silica, and organic materials such as color lake (color lake is the organic dye that is fixed on metal-salt or the oxide compound), with other material, this is well known in the art.These materials have kinds of surface character, and single personal care composition or preparation can use some different described pigment or other cosmetic powder composition, and they have some different coatings.Yet undesirable interaction can take place in described different coating each other.Therefore, for avoiding interacting and, it is desirable to carrying out identical processing to all particulates (particulate) in the customization agent for for the purpose of simple and easy.Better is, carries out single hydrophobicity and handles, and this is effective to the most frequently used pigment.

In addition, specific mineral dye lacks the affinity to skin.Hydrophobic modified skin affinity and the binding property enhancing that makes described pigment to skin, thus make cosmetic formulations on skin, produce better painted result, and produce better wearing quality; For example, more long lasting effect.In addition, improved overall skin skin feel feel (overall skin feel).Yet even it is hydrophobic modified to use state-of-the-art to carry out, the honorable effect pigment of king-sized particle such as height still can feel coarse on skin.Therefore, if the skin feel that the processing that exists can be given smooth (smooth), soft and smooth (silkyl) to macrobead, the sensation that does not produce the wax sample or be clamminess simultaneously then is favourable.

According to the present invention, can apply multiple granules of pigments surface with silicone compounds.The example of the granules of pigments that can handle according to the present invention includes but not limited to mineral dye, metal oxide, metal hydroxides, mica, pigment dyestuff, pearly pigment, inorganic silicate, porous material, carbon, coated interference pigment etc.

The example that can carry out the mineral dye of modification according to the present invention is ultramarine blue (ultramarineblue), ultramarine violet, Prussian blue, manganese violet, the mica that is coated with titanium, pearl white, ferric oxide, ironic hydroxide, titanium dioxide, lower titanium oxide (titanium lower oxides), chromium hydroxide and chromic oxide, and based on the pigment (for example carbon black) of carbon.In these pigment, usually according to the present invention to ultramarine blue and Prussian blue modification.

Well known in the art is usually ultramarine blue (that is the lagoriolite of sulfur-bearing (sodium aluminumsilicate containing sulfur)) to be expressed as Na _6-9Al ₆Si ₆O ₂₄S _2-4, and in multiple field (for example, coating composition, paint, China ink, makeup and washing composition), be used as blue inorganic pigment routinely and widely.The ultramarine blue possess hydrophilic property and in air atmosphere the highest about 250 ℃ temperature be stable.Yet although ultramarine blue is stable to alkali usually, it is unstable to acid.For example, (for example, in the presence of sulfate radical) ultramarine blue decomposes generation hydrogen sulfide gradually under acidic conditions.As a result, the ultramarine blue of gained decolours and bleaches.Obviously, producing hydrogen sulfide is undesirable especially in cosmetic field for example.And ultramarine blue may or heat and generation hydrogen sulfide owing to mechanical shear stress (for example, grinding).Eliminate these shortcomings although carried out multiple trial, examined as shown in open text (Kokoku) 50-27483 of patent application as open text (Kokai) 54-95632 of Japanese Unexamined Patent Application and Japan, but from practical standpoint, its effect is abundant inadequately.

Yet, when with the silicone compounds of formula (1), (2) and/or (3) ultramarine blue being carried out modification according to the present invention, the generation of the hydrogen sulfide that can prevent effectively under acidic conditions or cause at high temperature or mechanical shear stress, and can suppress the ultramarine blue Decomposition that spices (perfumes) for example causes.Therefore, when the ultramarine blue that under acidic conditions, uses through the silicone compounds modification of formula (1), (2) and/or (3), in aluminum container or in silver-colored container or in makeup, take place substantive the decomposition.And, because the ultramarine blue of described modification is coated with described silicone compounds layer, so present hydrophobicity and improved wettability (wettability).Therefore, the ultramarine blue of described modification can be formulated in the oil phase of emulsion system.

The above-mentioned inherent defect of ultramarine blue be considered on the ultramarine blue particle surface sulphur (that is surperficial sulphur) existence caused.This surperficial sulphur is to be present in the lip-deep living radical type of ultramarine blue lattice sulphur (active radical-type sulfur), and described living radical type sulphur may be to for example acid, heat or mechanical shear stress effect sensitivity.Yet,, the ultramarine blue particle surface is covered with described particle stabilizedization of ultramarine blue with described silicone compounds layer according to the present invention.And, because described silicone compounds layer has high-clarity, so between the ultramarine blue particle of unmodified ultramarine blue particle and modification, do not have substantive difference.

The ultramarine blue that carries out modification according to the present invention can be conventional arbitrarily ultramarine blue particle, and size for example is 0.1 to 100 micron.Depend on particulate surface-area and activity, be generally about 0.1 weight % to 20 weight % in the amount of the silicone compounds that in stable ultramarine blue powder particle, exists, be preferably 0.2 weight % to 10 weight % through stable particle weight through stable particle weight.If wish, can be with the ultramarine blue particle drying before handling.And, for example be coated with the plastics of ultramarine blue or the conventional composition powder particle of metal oxide and also can handle according to the present invention.

Well known in the art is that Prussian blue (that is ferriferro cyanide) is typically expressed as MFe[Fe (CN) ₆] (wherein M represents K, NH ₄Or Na), and routinely and widely in multiple field (for example, coating composition, paint, makeup), be used as blue inorganic pigment with powerful colouring power.Yet although Prussian blue acid resistance is strong, its alkali resistance is poor.And Prussian blue to adding thermally labile, heating causes decomposing or decolouring is dun.In addition, when when heating, Prussian blue to reducing sensitivity and tend to cause the rotten of coexisting substances (for example, spices).

Yet, when during to Prussian blue modification, eliminating conventional Prussian blue above-mentioned shortcoming with the silicone compounds of formula (1), (2) and/or (3) effectively according to the present invention.Therefore, the Prussian blue of described modification is formulated in composition such as makeup and the pharmaceutical composition, and because can eliminate Prussian blue and undesirable interaction other component (for example, spices), so composition stable significantly improves.And, because described silicone compounds layer is a highly transparent, so between the Prussian blue particle of unmodified sum modification, do not observe the substantive difference of color.

The Prussian blue powder particle that carries out modification according to the present invention can be conventional arbitrarily Prussian blue powder particle, is preferably dimensioned to be 0.01 to 100 micron, more preferably 0.05 to 0.1 micron.Depend on the particulate surface-area, the amount of the silicone compounds that applies on the Prussian blue particle surface of modification is generally 0.5 weight % to 40 weight %, more preferably 5 weight % to 30 weight %.

Can carry out the metal oxide of modification according to the present invention, the example of metal hydroxides is magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide, aluminum oxide, aluminium hydroxide, silicon-dioxide, ferric oxide (α-Fe ₂O ₃, γ-Fe ₂O ₃, Fe ₃O ₄, FeO), ironic hydroxide, titanium dioxide, lower titanium oxide, zirconium white, chromic oxide, chromium hydroxide, manganese oxide, cobalt oxide (cobalt oxides), nickel oxide and zinc oxide.These oxide compounds and oxyhydroxide can use separately or use with its any mixture.And, also can use composite oxides and complex hydroxide such as iron titanate (iron titanate), cobalt titanate (cobalt titanate) and Leyden blue (cobalt aluminate) in the present invention.Also can use in the present invention containing metal oxide compound or metal hydroxides matrix material (for example, be coated with titanium oxide mica, be coated with the nylon of ferric oxide), described metal oxide, metal hydroxides are coated on the core.

Although the size to described metal oxide powder particle or metal hydroxides powder particle does not have strict the qualification; but preferably; the enough described silicone compounds of energy apply and do not cause the agglomerant metal oxide of powder particle or metal hydroxides to be of a size of 0.001 to 500 micron simultaneously, are preferably 0.01 to 200 micron.The kind and the surface-area that depend on metal oxide or metal hydroxides, the coated weight of described silicone compounds are preferably 0.1 weight % to 20 weight %, more preferably 0.2 weight % to 10 weight %.

Well known in the artly be that metal oxide, metal hydroxides for example are used as tinting material or routinely and widely as magneticsubstance in multiple Application Areas (for example, coating composition, paint, makeup, China ink).Yet, common metal oxide compound, the common possess hydrophilic property of metal hydroxides, and therefore it has poor dispersiveness in oil or organic solvent.And metal oxide, metal hydroxides have catalytic activity, and therefore because surfactivity causes coexisting substances rotten with oil and spices as fat, perhaps cause decolouring.

On the other hand, when according to the present invention with the silicone compounds of formula (1), (2) and/or (3) during with metal oxide, metal hydroxides modification, the metal oxide of gained, metal hydroxides are coated with described silicone compounds layer equably on its whole surface, therefore and, make them not interact and do not cause the spices iso-metamorphism with other reagent with described metal oxide, metal hydroxides stabilization.Therefore, when metal oxide, metal hydroxides with described modification were formulated in the various compositions (for example, coating composition, paint, makeup, pharmaceutical composition), various compositions stability in time significantly improved.And, because described silicone compounds layer is extremely thin and transparent, so between untreated and the metal oxide handled, metal hydroxides, do not observe color distinction, and the magnetic (if existence) of metal oxide, metal hydroxides do not had a negative impact.Therefore, advantageously can be with the γ-Fe of described modification ₂O ₃Or cobalt-γ-Fe ₂O ₃Be used for the preparation of magnetic pipe recording material.

The micaceous example that can carry out modification according to the present invention is the artificial or synthetic mica of the hydroxyl in white mica (muscovite), phlogopite (phlogopite), biotite (biotite), sericite (sericite), rubellan (lepidolite), paragonite (paragonite) and the fluorine atom replacement stream natural mica and bakes and banks up with earth or calcinate.These pigments, mica can be used separately or use with its any mixture.

Although can carry out modification to raw mica ore deposit (raw mica ore) according to the present invention, the micaceous that can be according to the present invention carries out modification with the silicone compounds of formula (1), (2) and/or (3) is preferably dimensioned to be 0.5 to 200 micron.Yet, can be cleaved into thin form (for example, thin slice) afterwards at mica, according to the present invention described mica is carried out modification.Although the micaceous size is not had strict the qualification, but in the situation of intrinsic mica (inherent mica), the coated weight of the silicone compounds of formula (1), (2) and/or (3) is preferably 0.1 weight % to 20 weight %, more preferably 0.2 weight % to 10 weight %.Yet, when the silicone compounds of the excessive formula (1) of introducing the steam form, (2) and/or (3), owing to the micaceous cracking takes place, causes described mica to expand (expand), and therefore can use the silicone compounds of 20 weight % to 90 weight % at the most.

Well known in the artly be, mica is routinely with widely at for example coating composition, China ink and makeup, and is used as filler or additive in plastics and the rubber.Yet, the common possess hydrophilic property of mica, and therefore in oil and organic solvent, have poor dispersiveness.And when mica being mediated to plastics and rubber, mica may produce gathering and evenly mediate is difficult.

On the other hand, when according to the present invention with the silicone compounds of formula (1), (2) and/or (3) during to the mica modification, the mica of described modification is coated with the silicone compounds thin layer equably on its whole surface, and therefore makes the mica stabilization.Therefore, when the mica with described modification was bonded in the composition, mica can not make coexisting substances (for example, spices) decompose or be rotten, and therefore improved makeup and pharmaceutical composition stability in time significantly.And, because described silicone compounds layer is thin and transparent, so the color between the mica of untreated mica and modification does not have substantive difference.In addition, the mica of described modification presents hydrophobicity, and in the situation of emulsion, it can be formulated in the oil phase.

Can be according to the present invention with formula (1), (2) or the silicone compounds of (3) example that carries out the pigment dyestuff of modification be C.I.15850, C.I.15850:1, C.I.15585:1, C.I.15630, C.I.15880:1, C.I.73360, C.I.12085, C.I.15865:2, C.I.12075, C.I.21110, C.I.21095 and C.I.11680, C.I.74160, and the zirconium of following material, barium or aluminium color lake: C.I.45430, C.I.45410, C.I.45100, C.I.17200, C.I.45380, C.I.45190, C.I.14700, C.I.15510, C.I.19140, C.I.15985, C.I.45350, C.I.47005, C.I.42053 and C.I.42090.

In addition, can handle the surface of these pigment dyestuffs with for example rosin.

Although the size to described pigment dyestuff does not have strict the qualification, the pigment dyestuff that can apply or cover with the silicone compounds of formula (1), (2) and/or (3) is preferably dimensioned to be 0.05 to 100 micron.The kind and the surface-area that depend on described pigment dyestuff, the coated weight of silicone compounds are preferably 0.1 weight % to 20 weight %, more preferably 0.2 weight % to 10 weight %.

Well known in the artly be, pigment dyestuff is routinely with widely at for example coating composition, China ink and makeup, and is used as tinting material in plastics and the rubber.Yet, when being formulated into conventional pigment dyestuff or its surface-treated product in the composition, because them and the interaction of coexisting substances (described interaction is based on the surface of conventional pigment dyestuff and its surface-treated product and has avtive spot), described conventional pigment dyestuff and its surface-treated product cause the decomposition of coexisting substances or go bad.And because for example absorption or the desorb of crystal water, some pigment dyestuff produces decolouring.

On the other hand, when according to the present invention with the silicone compounds of formula (1), (2) and/or (3) during with the pigment dyestuff modification, the pigment dyestuff of described modification has the silicone compounds homogeneous layer that covers its whole surface.Therefore, the pigment dyestuff of described modification becomes stable and does not have interaction activity with coexisting substances.Therefore, when the pigment dyestuff with described modification is formulated in the composition, improved described composition stability in time significantly.And, because described silicone compounds layer is thin and highly transparent, so the color of described pigment dyestuff is before handling and do not have difference afterwards.In addition, also improved its dispersiveness in vehicle.

The example of pearly pigment (pearlescent pigments) (or pearly pigment (nacreous pigments)) is to contain titanium dioxide, lower titanium oxide, titanium oxynitrides mica-titanium composite material, mica-ferric oxide composite material, pearl white and the guanine as titanium component.Mica-titanium composite material and coloured pigment such as ferric oxide, Prussian blue, chromic oxide (chromium oxide), carbon black and famille rose can be mixed.These pearly pigments can use separately or use with its any mixture.

Although the size of described pearly pigment is not had strict the qualification, can be according to the present invention be preferably dimensioned to be 1 to 200 micron with layer pearly pigment that on its whole surface, applies or cover of the silicone compounds of uniform formula (1), (2) and/or (3).Notice that in the situation of pearly pigment, powder particle preferably is the form of planeform (for example, thin slice).The preferred coated weight of described silicone compounds is approximately 0.01 weight % to 20 weight %.

Well known in the artly be that pearly pigment for example is widely used in coating composition, China ink, makeup, plastics, pottery, decoration, daily necessities and fibre product or the textiles.Usually mica is formulated in these compositions with coloured pigment, to present various coloured appearances.Yet, when mica composite material is used with other material, can make described matrix material itself rotten, perhaps described matrix material causes coexisting substances decolouring or rotten.Another problem of pearly pigment is, these granules of pigments can not be as other inorganic or pigment dyestuff be ground in the oil phase because unique pearly-lustre, gloss and honorable effect depend on particle size, and process of lapping can change particle size.For cosmetic formulations, it is important that color effects is passed to skin.Yet pearly pigment has low-down affinity to skin usually, and feasible preparation to makeup requires the weather resistance of color effects on higher and the reduction skin.In addition, their airborne dust character makes that pearly pigment is difficult to handle, and the big pearly pigment of particle size stays uncomfortable harsh feeling on skin.

On the other hand, according to the present invention, when pearly pigment being applied equably or covering,, and do not cause going bad or decomposition of coexisting substances with gained pearly pigment stabilization with the silicone compounds film.They easily can be stirred in the oil phase of preparation and viscosity not produced big influence simultaneously, and they adhere to skin better, thereby improved the total application performance in makeup.Another advantage is, the pearly pigment that applies according to the present invention presents good skin feel, thereby even provides smooth and soft and smooth quality to the pigment of high particle size.We also find, have improved colour intensity (color intensity) and have obtained metalluster (metal-like shine).Other benefit is to have reduced airborne dust problem (dusting issue) significantly.

The example that can carry out the inorganic silicate of modification according to the present invention is layered silicate and tectosilicate such as pyrophyllite, talcum, chlorite, chrysotile, antigorite, lizardite, kaolinite, dickite, nakrite, halloysite, montmorillonite, nontronite, saponite, sauconite (sauconite) and wilkinite; Natrolite class (natrolites) is as natrolite (natrolite), mesolite, scolecite and thomsonite; Heulandite class (heulandites) is as heulandite (heulandite), stilbite, epistilbite; And zeolite such as euthalite, harmotome (harmotone), phillipsite, chabazite (chabazite) and sarcolite.These silicate mineralss can use separately or be used in combination with it.Layered silicate can be at it each layer have organic cation at the interface, perhaps can be substituted with alkalimetal ion or alkaline-earth metal ions.Described tectosilicate can comprise metal ion in its fine porosity.
