The present invention details the use of starch silicate and starch siliconates in personal care formulations to enhance or provide aesthetic properties to skin care products. These properties can range from smoothness and silky feel to non-greasy and non-oily. These starch derivatives provide an alternative to organically modified starches which can be expensive to prepare and require the addition of inorganic salts to functionalize the reagents.

A surface treatment agent or a powder treatment agent comprising a co-modified organopolysiloxane is disclosed. The co-modified organopolysiloxane is represented by the general formula: R.sup.1.sub.aR.sup.2.sub.bQ.sub.cSiO.sub.(4−a−b−c)/2. The co-modified organopolysiloxane has a number average molecular weight of less than 4500 and includes a long-chain alkyl group and a polyoxyalkylene group in the molecule.

The present invention relates to a long-lasting powder essence composition with improved coloring and skin feeling and its preparation method. The powder essence composition is a high-fitting coloring powder not likely to smear or wear off. The composition turns into liquid the moment it is rubbed on the skin to offer a natural color tone like water color, keeps the color clear without getting cakey even when it is reapplied multiple times, and delivers a clearer color as it glides on the skin to break powder and water particles. The powder essence composition according to the present invention is also a powder emulsion, which makes the skin feel light and hydrated rather than sticky or stuffy when applied to the skin and stays long due to its water-resistant function. In addition, the powder essence composition according to the present invention contains different functional moisturizing agents to provide plenty of nourishment when applied to the skin. The composition makes the skin feel fresh and hydrated rather than stuffy or heavy, lightly sinks into the skin like nothing is applied on the skin, to display a strong tint function, stays long just with one touch and has a good water-resistant effect, so it does not bleed when in contact with water.

An objective of the present invention is to provide a solid powder cosmetic excellent in impact resistance and usability despite that boron nitride and spherical resin particle are blended in a large amount. The present invention provides a solid powder cosmetic comprising: 12-30 mass % of synthetic fluorphlogopite iron; 5-15 mass % of boron nitride; and 5-15 mass % of phenyl-modified silicone spherical elastic powder.

A thickened composition for a cosmetic product including a content that is taken through a mesh contains a fine particulate powder and a silicone crosspolymer having a structure where dimethicone is cross-linked with an organic group, and has a storage modulus G′≥3000 Pa, as measured with a rheometer under the conditions of a gap of 0.5 mm, a strain oscillation angle of 0.1%, a frequency of 1 Hz, and a temperature of 25° C. while increasing stress applied with a 25 mm φ cone plate, and a loss tangent tan δ≤0.2, as calculated as a loss modulus G″ measured under the same conditions divided by the storage modulus G′. A cosmetic product includes a container including an inner lid with a tight mesh and an outer lid for tightly closing a container body, and the thickened composition contained in the container body under the inner lid.

A powder dispersant includes an ester compound of a polyglycerol having an average degree of polymerization of the polyglycerol, calculated from its hydroxyl value, in the range 2 to 20, a monovalent carboxylic acid or at least one derivative thereof, and a divalent carboxylic acid or at least one derivative thereof.
