Definitions
- the present invention relates to compositions having balanced UVA and UVB protection properties and more particularly to UV protective cosmetic products incorporating titanium dioxide and transparent iron oxide.
- UV B light was the primary cause of skin damage. Certainly, reddening and sunburn are largely caused by ultraviolet B exposure. However, while it was not initially recognized, ultraviolet A exposure, in addition to tanning, likely causes long-term damage, including skin cancer and premature aging. Ultraviolet A light is in the range between 400 nm and going down to 320 nm. Ultraviolet B light begins about 320 nm and goes down to about 290 nm. The differences in wavelength are key to providing protection from the sun.
- references to particle size within this specification refer to the shortest dimension of a pigment particle. For example, if a pigment contains acicular particles which are 20 nm x 100 nm, such particles are referred to as having a size of 20 nm. Moreover, references to particle size refer to the primary particle size of the powder ingredient. In various compositions, there may be some measure of conglomeration which would result in conglomeration sizes (i.e. secondary particle sizes) which are larger. Likewise, references to particle size are to the average size of the shortest dimension for an ingredient, as is the custom in the industry.
- EP06164522 to Boots relates to 15 nm and 35 nm to about 50 nm titanium dioxide particles which can protect the skin against UVA and UVB light.
- the sunscreen products that are claimed therein are to some extent transparent to visible light.
- other formulations providing broad spectrum protection are focused on transparency.
- the prior art attempts to achieve broad spectrum protection by incorporating low refractive index pigment zinc oxide in combination with titanium dioxide.
- novel cosmetic products incorporating titanium dioxide and transparent iron oxide are provided.
- the invention contemplates sunscreen formulation involving the use of particles of different sizes.
- particles in the 10 nm range may be very effective in reducing ultraviolet B light.
- they may be incorporated in relatively large quantities into a sunscreen formulation.
- a high SPF sunscreen formulation may be achieved with minimal whitening of the skin.
- larger particles for example, 50 nm and 60 nm are also incorporated in the formulation with the object of longer wavelengths of light, for example, light in the ultraviolet A range.
- 60 nm particles are particularly effective in providing protection against ultraviolet A light.
- PA protection against ultraviolet light
- PFA protection against ultraviolet A light
- chalkiness in the appearance of applied sunscreens is reduced.
- a blend of white sunscreen material such as titanium dioxide
- a quantity of colored sunscreen material such as an iron oxide or iron hydroxide.
- the colored sunscreen material is small enough to be characterized as transparent, it imparts color to the whitish chalky appearance of the other, for example titanium, component.
- the amount of, for example, red iron oxide and/or yellow iron oxide, in a formulation is kept at a level which is below that which would provide unacceptable darkening or coloring of the skin. While, the iron oxides do contribute opaque as well as transparent color, the level of the iron oxides is maintained at a low enough value to achieve an acceptable aesthetic appearance.
- the inventive cosmetic products which may take the form of liquid, creme, stick, compact and other products, are effective products for protecting the skin from sunlight as they contain titanium dioxide and iron oxides of various particle sizes.
- the inventive products are unlike untinted beach wear sunscreen products, which are expected to be and to varying extents are transparent to visible light in order to avoid undesirable skin whitening. They are also unlike conventional cosmetic products are formulated to provide opacity and cover skin blotches, wrinkles and other imperfections, as well as impart a desirable color and finish to the skin.
- the inventive products achieve an attractive aesthetic and a large measure of protection by combining what might be regarded as unacceptable amounts of white opacity, colored opacity and colored transparency to provide substantially transparent tinted products having excellent and balanced UV protection.
- the cosmetic products contemplated by this invention are color cosmetic products and are typically transparent to modestly opaque products, although they may have lower coverage to make them suitable as make-up primers or cosmetic products for teens. Furthermore, the cosmetic products contemplated by this invention are sunscreen products that provide high amounts of protection against ultraviolet A (UVA) and ultraviolet B (UVB) light.
- UVA ultraviolet A
- UVB ultraviolet B
- An essential component of the cosmetic products contemplated by this invention are that they protect the skin against high amounts of UVA light, which is believed responsible for long-term harm to the skin.
- the present invention also contemplates the design of cosmetic products with a PA (Protection Against UVA) value of 10.0 or greater measured in-vivo using the Japanese method PPD, (Persistent Pigment Darkening) or an equivalent in-vivo method.
- the present invention is also aimed at satisfying the requirements of dermatologists, many of whom are requiring sunscreen products mat have high amounts of UVA protection.
- SPF to PA protection There is presently a strong preference by many dermatologist for sunscreen products with a fixed ratio of UVB to UVA protection (SPF to PA protection). This ratio may be described as the UV balance ratio.
- the cosmetic products contemplated by this invention allow the achievement of an SPF of at least 30 and a PA of 10 and higher for a UV balance ratio of 3.0 to 1.0 and lower.
- Titanium dioxide and iron oxides are available at various particle sizes. During the late 1980's titanium dioxide was typically supplied in three sizes 15 nanometers, 35 nanometers, and pigmentary grades larger than 200 nanometers. Presently, many different particle sizes are available ranging from 10 nm to 300 nm, and even several microns.
- transparent red iron oxide Fe 2 O 3
- transparent yellow iron oxide Fe 2 O(OH)
- transparent black iron oxide Fe 2 O 4
- Particulates are selected keeping in mind UV attenuation.
- the quantities of all particulates are balanced for a pleasant aesthetic effect as noted herein.
- iron oxides provide attenuation against UVA and UVB light, because they scatter and absorb light. Pigmentary iron oxides can contribute more than 0.5 SPF and PA unit per weight percent. The contributions of transparent iron oxides to UV attenuation appear to be greater than for pigmentary grades in cosmetic products. In addition, the aesthetics of the inventive combinations are markedly superior to that achievable with titanium dioxide or zinc oxide based products.
- the cosmetic products contemplated by this invention seek to provide a PA of at least 10 and a UV balance ratio (UVB :UVA) of 3 to 1 or lower.
- a likely achievable SPF contemplated by this invention is an SPF of 50 with a PA of 17 and this is believed to be sufficient to protect against sunlight for most commonly encountered circumstances.
- the cosmetic products contemplated herein attain these high levels of protection using at least 5% of a 35 nm titanium dioxide and roughly about 1.0% or more of a transparent iron oxide, dependent upon the aesthetic result desired.
- Other particle sizes of titanium dioxides and iron oxides may be added to increase SPF and opacity, similarly, zinc oxide may be added where formulations with less opacity are desired. Larger amounts of UVA attenuating transparent iron oxides will reduce transparency and darken the composition without compromising the acceptability of the aesthetics as appears below.
- KLF-036 and KLF-036A are aqueous-based products.
- KSL-027 and KSL- 027A are oil-based products.
- PA stands for protection against UVA light. UV balance is the ratio of SPF to PA. Measurements of PA were taken by Consumer Products Testing Co., an independent laboratory. Measurements of SPF were also taken by Consumer Products Testing Co. EXAMPLE l
- K 2005-76 The ingredients of a first product formulated in accordance with the invention and usable as a moisturizer or sunscreen are shown in Table 2.
- This product was designated K 2005-76 and was developed with the objective of providing a foundation with high UVA by combining a number of different particle size titanium dioxides and incorporating transparent iron oxides.
- K 2005-76 was made using a titanium dioxide dispersion sold under catalog number CM3EK25VM by Kobo Products, Inc. This dispersion catalog number CM3EK25VM contains 19.5% active titanium dioxide, by weight that is the weight of the titanium without the weight of surface treatment coatings or the like.
- K 2005-76 also incorporated a treated titanium dioxide sold under catalog number KQ-MS 8 by Kobo Products, Inc. Catalog number KQ-MS8 contains 89.0%, active TiO 2 , by weight.
- An emollient light ester base comprising, principally, isononyl isononanoate, silicones, water, waxes and pigments provides moisturization on account of the humectant characteristics of the esters and butylene glycol.
- bases to provide moisturization may be contemplated by the present invention. These bases may include any of the materials typically used as bases in prior art cosmetic formulations.
- the transparent iron oxides noted in Table 2 synergize with the titanium dioxide ingredients to provide an excellent SPF.
- a high PA is also provided in a formulation which has excellent aesthetic appeal.
- the surface-treated colors, namely the isopropyl titanium triisostearate treated iron oxides in WE55Y, WE70R, and WE70B dispersions deliver smooth application and slip on skin with excellent wear.
- Velvesil 125 is used in the inventive formulation to give the product a velvety, cushion-like texture. Naturally, other additives may be used in place of Velvesil 125.
- the active ingredients of K 2005-76 are the various titanium dioxides which together compromise approximately 19.77% of the final product by weight together with the iron oxides.
- a first phase is formulated by slowly adding quaternium- 1 S hectorite to isononyl isononanoate while stirring with a Cowles brand dissolver in a stainless steel beaker at high speed for 20 minutes.
- the ethyl alcohol 39C is added to the first phase and stirred for an additional 20 minutes.
- Ethyl alcohol 39C is USP grade of ethyl alcohol. The mixture is then set aside. In time, the same develops into a lucentite gel.
- the lucentite gel (or, alternatively, any organophilic gel such as versagel, bentones, lucentite or any suitable smectite clay or polymer gel) of phase 1 is combined with the transparent iron oxide slurry of phase 2.
- the same is stirred at high speed for 30 minutes with a dispersator (such as the Cowles dissolver) until the mixture is homogenous to form a pre-formed color gel phase.
- C.I. refers to Color Index Number.
- Phase 3 is then stirred with a Cowles brand dissolver for 5 minutes.
- One men slowly adds the pre-formed color gel phase, made by combining phase 1 and phase 2 to phase 3 to form the base.
- the base is then stirred with a Cowles brand dissolver for 5 minutes.
- the sorbitan isosterate of Part 4 is added to the base and mixes for an additional 10 minutes at a high speed with a Cowles brand dissolver. Mixing is then continued for an additional 60 minutes while heating to a temperature in the range of about 60-65 degrees Celsius.
- the mixture is mixed for an additional five minutes. Such mixing may be done with the Cowles dispersator. The material is removed from the Cowles dissolver and then mixed with a Silverson at 8000 rpm using the largest screen supplied in a steam bath.

- a typical formulation for such a dispersion is given in Table 15.
- the particulates used may be hydrophobic or hydrophilic and may be incorporated in water or oil vehicles as is known in the prior art for such materials.
- such a formulation may be achieved by putting solvents (in an amount of approximately equal in weight to the weight of the particulates) such as cyclopentasiloxane and ethyl trisoloxane in a mixing tank. Next, a surfactant is dissolved in the solvents. Lastly, the particulates as detailed in Table 15 are headed. The particulates are men mixed with the surfactant and solvent at approximately 500 rpm with the disburse or blade. The mixture is then transferred to a mixing tank and subsequently milled using a bead mill to the desired particle size.
- a dispersant such as polyhydroxystearic acid may be used without the need for using hydrophobized particulates, despite the use of a nonaqueous vehicle.
- hydrophobized particulates may be used in an oil, or other nonaqueous vehicle.
- the incorporation of the particulates may also be made into an aqueous base, or a silicone based carrier vehicle.
