Description

Skin care moisturizing and sunscreen composition containing organic particulate matter {SKIN CARE MOISTURIZING AND SUNSCREEN COMPOSITIONS COMPRISING ORGANIC PARTICULATE MATERIAL}

The inclusion of ingredients with moisturizing, skin care and UV blocking efficacy has long been known for the characteristics of many types of topical compositions, including skin care compositions. Such compositions are used to increase the moisture content of the skin and to protect the skin from the deleterious effects of ultraviolet radiation. Today's consumers are exposed to conditions where the skin is prone to dryness, such as in an air-conditioned office, and in an environment where UV radiation is becoming more harmful due to the destruction of the ozone layer. There is a growing interest in skin care products that can give, especially products for the face.

However, especially skin agonists such as organic sunscreens, water soluble wetting agents and vitamins can be highly sticky to their skin feel, so compositions containing significant levels of these ingredients may have poor skin feel, such as excessive oiliness, stickiness and attraction. Have a last name Furthermore, when such excess levels of wetting agent are used with thickeners, the stickiness can be even worse. So far, consumers have been trying to make topical compositions by minimizing the amount of the ingredients to provide an acceptable skin feel when using the final product while at the same time removing the ingredients to an efficacy level of the efficacy. To this end, in order to obtain acceptable skin sensitization, the topical composition contains a highly effective and highly cohesive ingredient at a sub-optimal level and is applied several times over an extended period of time required to achieve a desired skin effect. There was a tendency. Since the most tacky components are mostly water soluble, these components are most problematic for topical compositions in aqueous continuous phase. This strong adhesive component is in the aqueous phase or dissolved because the level of contact with the skin when using the product. Therefore, it is most desirable to provide an aqueous continuous topical composition that contains an effective level of skin care efficacies such as moisturizing and sunscreen efficacy while at the same time feeling consumer acceptable skin texture.

To date, in skin care compositions, the inclusion of particulate matter, including organic and inorganic particles, has been known to affect the texture of the skin as well as the composition itself. For example, an article entitled "Quantification of the Soft Focus Effect" on pages 57-61 of Cosmetics & Toiletries No. 111 of July 1996 discloses that wrinkles on the skin can be physically filled with reflective materials such as TiO ₂ . . US-A-4,892,726, issued by Toshiba Silicone, describes the use of polymethylsilsesquioxane powders in makeup and cosmetic compositions that add a soft, natural color when applied. These particles are currently Tospearl from Toshiba Silicone. It is available in various particle size grades under the name. WO 00/24372 describes a topical composition containing 0.5% to 25% of a particulate matter having a refractive index of 1.35 to 1.6 and a particle size of 2 μm to 30 μm, which composition improves various skin appearances such as vitamin B3 compounds and retinoids. Combining with them to give the appearance of the skin. Similarly for the particles disclosed herein, the median particle size of about 4.5 μm toperolol 145A is included. Similarly, co-pending application PCT / US99 / 04748 discloses topical compositions containing 0.1-10% of organic particulate matter of 1.3-1.7 refractive index, suitable for improving skin feel and appearance upon use. EP-A-692,242 discloses the use of hollow, denaturable particles of size 1 to 250 μm, most preferably 18 μm, to reduce the tackiness of essentially anhydrous compositions containing high amounts of fatty materials. . EP-A-908,175 discloses a stable cosmetic composition containing at least one fatty phase, crosslinked elastomeric organopolysiloxane and high levels of organosiloxane particles. EP-A-790,055 discloses the use of partially crosslinked elastomeric organosiloxane polymers for the preparation of compositions which impart a matte appearance to the skin, in combination with the fatty phase, preferably contained within the fatty phase. Doing. The above applications disclose various cosmetic compositions that result in an improvement in skin feel and even skin appearance. However, these applications do not disclose aqueous compositions having highly effective levels of moisturizing and UV blocking agonists.

The compositions and presentations of the prior art have led to developments in the field of skin beauty treatments and useful developments in combination with organic particulates and skin agonists. However, they did not fully show how to provide an effective topical moisturizing and UV blocking component to an aqueous topical composition that further provides a pleasing skin feel to the consumer.

Surprisingly, the addition of one or more organic particulates with a pronounced particulate size and critical surface tension to an aqueous continuous phase topical skin care composition containing a highly effective level of moisturizing and UV blocking ingredients can reduce the strong adhesiveness which was a disadvantage. Has been found. Importantly, the improvement of skin feel is significant enough to be obtained by mixing organically obtained UV blocking and high moisturizing effect in the preparation method. Previously, this mixing was not possible due to the high stickiness. In addition, it has also been found that when the organic particulates are premixed with low viscosity organosiloxane oils, the skin feel is even better.

Even without borrowing a theory, it can be seen that the inclusion of particulate matter minimizes friction in the use of the product. In the use of the product, the particles settle at the interface between the residue of the product and the air, and the particles remain on the surface of the residue. This minimizes the contact of skin and product residues and improves skin feel. In use, it is desirable to premix the fines with the carrier oil to ensure that the fines are delivered to the skin surface in the most effective way. The fines are completely wetted by the carrier oil, and the low viscosity of the premix, and therefore high mobility, ensures that the fines effectively spread on the skin surface when using the product.

It is an object of the present invention to present an aqueous continuous phase topical composition suitable for adding high levels of moisturizing and UV blocking effects to the skin. Another object of the present invention is to provide a topical composition containing particulate matter, such as polymethylsilsesquioxane, which offsets the tack in the formulation to deliver the desired skin feel. Another object of the present invention is to provide a composition useful for delivering a satisfactory level of moisturizing and UV blocking effect without the need for multiple uses.

The above objects and other objects of the present invention are apparent from the following specification.

The composition is preferably an oil-in-water emulsion. They may generally be prepared according to the procedures used in cosmetics, and materials similar in phase distribution, which are well known and understood by those skilled in the art, may be added in any order.

Preferably, the organic particulates are premixed slowly and homogeneously into the carrier oil before adding to the rest of the composition. This allows the organic particulates to offset the cohesive properties of the skin agonists more effectively than the particulates are added directly to the composition. Once the premix is formed, it must be added immediately to the rest of the composition to maintain efficacy. If the remaining composition is an emulsion, it is preferable to prepare the emulsion before adding the premix. This prevents the splitting of the premix, which is likely to cause high shear steps during emulsification.

In addition, the premix forms a stable phase that remains stable within the remaining composition, which can be observed as separate small droplets with a diameter greater than 0.1 μm when viewed at 40-fold magnification using a standard optical microscope. It is desirable to. However, it has been found that depending on the other components in the composition, there may be a shift from one phase to several other components when the composition is formed, thus preventing the premix from really continuing into a separate phase.

Carrier oil

The carrier oil preferably has a lower surface tension than the selected organic particulates and a viscosity of less than about 350 mPa · s, more preferably less than about 100 mPa · s, and more preferably less than about 75 mPa · s. The viscosity of the carrier oil is also measured at 31 ° C. (skin temperature) in the same manner as previously described for the whole premix.

The carrier oil is preferably an organosilicone oil selected from nonvolatile and volatile organosiloxanes, and mixtures thereof. The term "non-volatile" as used in this context refers to silicon which is liquid under ambient conditions and has a flash point (under 1 atmosphere) above about 100 ° C. The term "volatile" as used in this context refers to silicone oils having a flash point below 100 ° C. Suitable organopolysiloxanes can be selected from a variety of silicones having a wide range of volatilities and viscosities. Nonvolatile organopolysiloxanes are preferred. Suitable silicone carrier oils are disclosed in US Pat. No. 5,069,897, issued December 3, 1991.
