ABSTRACT:

FIELD OF THE INVENTION
This invention relates to improved stabilized shampoo compositions containing siloxysilicate materials commonly referred to as MQ resins. This case is related to a copending case, U.S. Ser. No. 09/169,656 filed Oct. 9, 1998, and owned by the same company.
BACKGROUND OF THE INVENTION
Human hair becomes soiled from exposure to environmental factors as well as from the sebum secreted by the scalp. The build-up of the sebum causes the hair to have a dirty and/or greasy feel and an unattractive appearance. It is the function of shampoo products to cleanse the hair and scalp by removing the excess dirt and sebum. However, it is also desired to cleanse the hair and scalp in such a way that the hair is left in an undamaged and manageable conditions. A number of approaches to formulating improved shampoos have included the creation of 2-in-1 products with conditioners (such as linear silicones) built into the shampoos. Rinse products may also be used as separate conditioning treatments and sprays can be used as detanglers.
A number of examples of conditioning shampoos and/or hair care products can be seen in U.S. Pat. No. 4,741,855 which describes shampoo compositions comprising 5-70% of a synthetic surfactant, 0.01-10.0% of an insoluble, non-volatile silicone, 0.5-5.0% of selected long chain derivatives and water.
Other background information may be found in U.S. Pat. Nos. 5,714,446; 3,907,984; 4,774,310; 4,223,009; 4,012,501; 5,684,112; and 4,728,457; and PCT case WO 92/17154.
There still remains a need for improved shampoo compositions, especially those which give benefits such as improved feel, manageability, shine and styling improvements (for example increased volume) to the hair. Thus it is an object to provide such shampoo compositions, particularly with the added benefit of being able to retain stability for the additives and at the same time delivering sufficient material to impart a beneficial effect. It is another object of the invention to provide shampoo compositions which contain MQ resins and to retain the stability of the compositions. It is yet another object of the invention to provide stable shampoo compositions which can be formulated with a variety of MQ resins depending on the types of properties desired, for example, increased shine, conditioning effects, reduced combing force, curl retention, volume and/or better manageability. These and other objects of the invention will become apparent from the following description.
SUMMARY OF THE INVENTION
The invention provides a detersive shampoo for cleansing the hair and providing improved feel, manageability, shine and styling improvements (for example increased volume) to the hair. The shampoo comprises:
(a) a detersive surfactant;
(b) a siloxysilicate resin (also called an MQ resin);
(c) a stabilizer for the siloxysilicate; and
(d) an aqueous carrier.
DETAILED DESCRIPTION OF THE INVENTION
The invention comprises stabilized shampoo formulations comprising:
(a) from 4-60% of a detersive surfactant (for example, 5-50% and, more particularly, 5-30%);
(b) from 0.1-15% of at least one siloxysilicate material (for example, 0.1-10% and, more particularly, 0.1-7.0%);
(c) from 0.10-7.00% of a selected stabilizing agent (for example, 0.1-5% and, more particularly, 1.5-3%); and
(d) the remainder being an aqueous carrier (optionally with other ingredients). Optionally other ingredients especially fragrance and/or preservative(s) may be included.
The surfactant can be selected from a variety of materials. Suitable surfactants include:
(a) anionics as described in U.S. Pat. No. 4,902,499 to Bolich et al and U.S. Pat. No. 4,963,348 to Bolich et al both of which are incorporated by reference herein such as

is alkyl or alkenyl of 10-20 carbon atoms, w is a number from 1 to 10, and M is a water-soluble cation such as ammonium, sodium, potassium and triethanolamine;
(ii) reaction products of fatty acids (for example, those derived from coconut oil) esterified with isethionic acid and neutralized with sodium hydroxide;
(iii) succinamates (for example disodium N-octadecylsulfosuccinates, tetrasodium N-(1,2-dicarboxyethyl)-N-octadecylsulfosuccinamate, diamyl ester of sodium sulfosuccicinic acid, dihexyl ester of sodium sulfosuccinic acid, and dioctyl esters of sodium sulfosuccinic acid; and
(iv) olefin sulfonates having 12 to 24 carbon atoms;
(b) amphoterics as described in U.S. Pat. No. 4,902,499 to Bolich et al and incorporated by reference herein such as:
(i) derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight chain or branched and wherein one of the aliphatic substituents contains from 8 to 18 carbon atoms and one contains an anionic water solubilizing group (for example, carboxy, sulfonate, sulfate, phosphate, or phosphonate) with examples of such compounds including sodium 3-dodecyl-aminopropionate, sodium 3-dodecylaminopropane sulfonate, N-alkyltaurines, N-higher alkyl aspartic acids (for example a products sold under the name “MIRANOL” as described in U.S. Pat. No. 2,528,378);
(ii) zwitterionic surfactants (broadly exemplified as derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic radicals can be straight chain or branched, and wherein one of the aliphatic substitutents contains from 8 to 18 carbon atoms and one contains an anionic water-solubilizing group (for example, carboxy, sulfonate, sulfate, phosphate, or phosphonate);
