SURFACE MODIFIED PIGMENT

Abstract

A composition comprising a pigment particle that is coated with a cationic material and isopropyl titanium triisostearate. The pigment particle can be included in a cleansing composition for deposition on a surface, such as skin.

Description

BACKGROUND OF THE INVENTION

There is a desire to increase the radiance of skin in such a way that consumers can perceive their skin being radiant, glossy, and/or shiny. These attributes are evaluated via consumer assessment. Skin radiance is also correlated to skin gloss measurements. While radiance can be imparted to skin by using a leave on product that deposits a pigment that can increase gloss, it would be desirable to be able to increase gloss by using a cleansing composition that includes a pigment.

The problem with using a cleansing composition is that the composition performs its function of cleaning by removing oil and dirt from skin. To be effective, the pigment needs to be modified to adhere to skin to avoid being washed away by the cleansing composition.

It is desirable to create a pigment that can adhere to skin that can be delivered from a cleansing composition.

SUMMARY OF THE INVENTION

A composition comprising a pigment particle that is coated with a cationic material and isopropyl titanium triisostearate. Also a method of increasing gloss on a substrate comprising applying the composition to the substrate.

Polyquaternium-67 is available from the Amerchol subsidiary of Dow Chemical Company under the SoftCAT trade name. In one embodiment, the Polyquaternium-67 is SoftCAT SK-MH.

In other embodiments, the cationic material is a cationic polymer. In the present application, the expression “cationic polymer” designates a polymer containing cationic groups or groups which can be ionized into cationic groups. In certain embodiments, cationic polymers are chosen from those containing units comprising primary, secondary, tertiary and/or quaternary amine groups which may either form part of the polymer chain or be carried by a side substituent. In certain embodiments, the cationic polymers have a molecular mass of between about 10³ and 3×10⁶). In certain embodiments, the cationic polymers used are those containing at least 10% by weight of units comprising amine groups or quaternary ammonium groups whose quaternization value, expressed as cationic equivalent per gram of polymer, is for example at least equal to 0.05 cationic meq/g (meq: milliequivalent). When the cationic polymer carries amine or quaternary ammonium groups carried by a side substituent, the polymer chain is for example an acrylic, vinyl, siliconized, fluorinated or saccharide chain. In certain embodiments, the cationic polymers are selected from quaternized proteins, quaternized polysiloxanes, polyamine type polymers, polyaminoamide and quaternary polyammonium.

The quaternized proteins are in particular chemically modified polypeptides carrying at the chain end, or grafted thereto, quaternary ammonium groups. Among these proteins, there may be mentioned especially:

Among these protein hydrolysates, there may be mentioned inter alia:

• CROQUAT M™ whose peptide chain has a mean molecular weight of about 2,500 and whose quaternary ammonium group comprises a C₁₀-C₁₈ alkyl group;
• CROQUAT S™ whose polypeptide chain has a mean molecular weight of about 2,700and whose quaternary ammonium group comprises a C₁₈ alkyl group;
• CROTEIN Q™ whose polypeptide chain has a mean molecular weight of the order of 12,000 and whose quaternary ammonium group comprises at least one alkyl group having 1 to 18 carbon atoms. These different products are sold by the company Croda.

Other quaternized proteins are those corresponding to the formula:

There may be mentioned for example the products sold by the company Inolex, under the name LEXEIN QX 3000™, termed in the CTFA dictionary “Coco-trimonium Collagen Hydrolysate”.

Among the quaternized proteins, there may also be mentioned quaternized plant proteins, such as wheat, maize or soya bean proteins; as quaternized wheat proteins, there may be mentioned those marketed by the company CRODA under the names HYDROTRITICUM WQ or QM™, termed in the CTFA dictionary “cocodimonium hydrolysed wheat protein”, HYDROTRITICUM QL™ termed in the CTFA dictionary “Laurdimonium hydrolysed wheat protein”, or alternatively under the name HYDROTRITICUM QS™ termed in the CTFA dictionary “Steardimonium hydrolysed wheat protein”.
