Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The invention concerns personal care compositions formulated with cationic diesters and dihydroxypropyl quaternary ammonium salts. 
         [0003]    2. The Related Art 
         [0004]    Amongst some groups of consumers, personal care compositions such as creams or lotions are at least partially judged effective by their dragginess during skin rub on. Dragginess in the minds of these consumers indicates the benefit of a faster absorption. 
         [0005]    Cationic esters have been exploited in topical cosmetics for their conditioning and pleasant skinfeel properties. U.S. Patent Application Publication No. 2008/0305056 A1 (Jenni et al.) reports the use of “ester quats” which are quaternized fatty acid alkanolamine esters and salts thereof for use in lotions and creams. Formulas with these materials exhibit low viscosity properties and have long-term storage stability. U.S. Pat. No. 5,759,557 (Epstein et al.) describes cationic emulsifiers such as dimethyl distearyl ammonium halide in combination with glycerin and a weakly acidic material providing a finished oil-in-water emulsion of pH 2.5 to 4.5. Another low pH skin treatment composition is found in U.S. Pat. No. 5,654,341 (Struewing). Therein a combination of cationic surfactant with a fatty acid is reported to form a complex preventing the cationic surfactant from irritating the skin while simultaneously substantially reducing pH of the compositions. U.S. Pat. No. 4,389,418 (Burton) describes skin care compositions that moisturize and condition based on a water-and-oil emulsion of petrolatum or mineral oil, a quaternary ammonium emulsifier, a fatty alcohol and a fatty ester emollient. The compositions are non-greasy and impart acceptable feel when applied to the skin. 
         [0006]    Dihydroxypropyl quaternary ammonium salts (hereinafter “glycerol quats”) have been reported as exceptional skin moisturizing agents and detackifiers. Representative disclosures include U.S. Pat. No. 7,659,233 B2 (Hurley et al.), U.S. Pat. No. 7,282,471 B2 (Harichian et al.) and EP 1 809 235 B1, all to Unilever. 
         [0007]    None of the disclosures on cationic esters or dihydroxypropyl quaternary ammonium salts have ever indicated either of these materials could impart dragginess during application onto a skin surface. 
       SUMMARY OF THE INVENTION 
       [0008]    A personal care composition is provided which includes:
       (i) from about 0.05 to about 10% by weight of a diester quat of the following structure (I):

The term “nonvolatile” refers to those silicones that are liquid or solid under ambient conditions and have a flash point (under one atmosphere pressure) of at least about 100° C. The term “volatile” refers to all other silicone oils. Suitable organopolysiloxanes include polyalkylsiloxanes, cyclic polyalkylsiloxanes, and polyalkylarylsiloxanes. 
         [0042]    Polyalkylsiloxanes can be represented by the general chemical formula R 3 SiO[R 2 SiO] x SiR 3  wherein R is an alkyl group having from one to about 30 carbon atoms (preferably R is methyl or ethyl) and x is an integer from 0 to about 10,000, chosen to achieve the desired molecular weight which can range to over about 10,000,000. Commercially available polyalkylsiloxanes include the polydimethylsiloxanes, which are also known as dimethicones. These include the Viscasil® series sold by the Momentive Chemical Company and the Dow Corning® 200 series sold by Dow Corning Corporation. Dimethicones include those represented by the chemical formula (CH 3 ) 3 SiO[(CH 3 ) 2 SiO] x [CH 3 RSiO] y Si(CH 3 ) 3  wherein R is straight or branched chain alkyl having from 2 to about 30 carbon atoms and x and y are each integers of 1 or greater selected to achieve the desired molecular weight which can range to over about 10,000,000.

         [0061]    The Samples of Table I were evaluated for their relative friction properties. This value was utilized to identify relative ability to impart a draggy effect onto skin. 
       Procedure 
       [0062]    The test is conducted in an environmentally controlled chamber at 21° C. and 30% relative humidity. Sample size of 0.1 mL is spread on a glass plate over a 6 by 2 inch area (2.54 cm to the inch). The plate is attached to the cross-head of an Instron Model 4501 Materials Testing System. A 3 by 1 inch aluminum sled is fitted with a rectangular foam pad 3 inches by 1 inch by 0.125 inch (Foamex® L2185040B2). A 100 gram weight is placed on the sled. It is then pulled across the same area at a rate of 10 cm/min., and a friction measurement taken immediately thereafter. The integral of force vs. a distance of 40 mm (i.e.—amount of work of dynamic slip friction units of gram-mm) is calculated for each of the intervals. Also measured is the static load (grams) or stick. Three runs are conducted for each product. Results are recorded in Table II.

         [0063]    Sample A and B evaluate the effect of 1% glycerol quat on lotions comparing distearyldimonium chloride (“dialkyl quat”) to diester quat. The higher values for Sample B indicates that in a diester quat system greater dragginess is imparted by the glycerol quat. Sample C is the formula wherein the glycerol quat is absent. Both the coefficient of static friction and Work are lower values than in Sample B. The lower values demonstrate dragginess for the combined diester quat and glycerol quat. As the amount of glycerol quat increases from 0.1% to 5%, dragginess increases. Compare Sample E to D.
