ABSTRACT:
FIELD OF THE INVENTION
This invention relates to the cleansers such as shampoos, liquid soaps, shower gels and similar products that are able to achieve improved pearlescence as compared to previous products made with other agents. In one aspect of the invention, 2-in-1 products with conditioning agents such as silicones are made which not only have improved pearlescence, but also have good stability.
BACKGROUND OF THE INVENTION
A variety of cleansers, especially conditioning cleansers such as shampoos (so called “2-in-1” products), liquid soaps and shower gels are available. Such products use silicones of various types in combination with some type of suspending agent of system. For example, U.S. Pat. No. 4,741,855 to Grote et al uses long chain esters of ethylene glycol, esters of long chain fatty acids, or long chain amine oxides as stabilizing agents. U.S. Pat. No. 6,165,454 to Patel et al, describes the use of selected acrylates such as Aculyn-33 as a suspending agent. U.S. Pat. No. 5,213,716 to Patel et al describes the use of long chain alcohols such as C20-C40 alcohols as stabilizers for silicone containing hair care compositions. Other patents as background include U.S. Pat. No. 5,348,736 to Patel et al; U.S. Pat. No. 5,051,250 to Patel et al; U.S. Pat. No. 5,106,613 to Hartnett et al; and U.S. Pat. No. 4,997,641 to Hartnett et all. Certain commercial products have tried using a combination of cetyl and stearyl alcohols for a stabilizing effect.
These previous attempts have resulted in some degree of success, but there still remains a need to obtain additional pearlizers, especially pearlizers which are capable of stabilizing compositions which contain silicones. In one particular embodiment, formulations are made which not only achieves good pearlescence, but also stabilizes cleansing compositions containing silicones at lower temperatures.
BRIEF SUMMARY OF THE INVENTION
The invention comprises the use of behenyl alcohol, a straight chain alkyl with an average of 22 carbons, in cleansers, especially shampoos. In one particular type of cleansers, a conditioning agent is also present. In particular, compositions of this invention comprise:
(a) 4.00-30.00 weight % (for example, 7-20 weight %) of an anionic material selected from the group consisting of water soluble lipophilic sulfates and/or sulfonates of 8 to 22 carbon atoms, preferably of 10 to 16 or 10 to 18 carbon atoms, more preferably of 10 to 14 or 16 carbon atoms;
(b) 0.25-4.0 weight % (for example, 1-2 weight %) behenyl alcohol.

(d) 0-10.00 weight % (for example, 0.05-10.00 weight % and more particularly 1-3 weight %) of an amphoteric material (sometimes referred to as a zwitterionic material) selected from the group consisting of derivatives of aliphatic quaternary ammonium, phosphonium or sulfonium compounds in which the aliphatic radicals can be straight chain or branched, and wherein one of the aliphatic substituents contains from 8-22 carbons and one contains an anionic water-solubilizing group (for example, a carboxyl, sulfonate, sulfate, phosphate or phosphonate) C8-C18 alkyl betaines and sulfobetaines, and C8-C18 alkyl amphoacetates and propionates;
(e) optionally a cationic material which is a cationic surface active fiber conditioning agent, which may be considered to be secondary conditioning agents in the invented fiber conditioning compositions, are selected from the group consisting of
(i) 0-5.0 weight % (for example, 0.05-5.0 weight % and more particularly 0.2-0.5 weight %) of one or more quaternary ammonium salts of formula:
wherein R

is a lower alkyl having 1-4 carbons; R
10
and R
11
may be the same or different and are each selected from the group of higher alkyls having 10-40 carbons; R

is a salt forming anion selected from the group consisting of a halide (for example, chloride and bromide), lower (C1-C3) alkylsulfates (for example, methosulfate and ethosulfate), lower (C1-C3) carboxylic acid radicals (for example, acetate) and citrate; and
(ii) 0.0-2.0 weight % (for example, 0.05-0.4 weight %) of one or more water soluble cationic cellulosic polymers selected from the group consisting of hydroxy alkyl celluloses, alkyl hydroxy alkyl celluloses, galactomannan gums;
(f) 0-5 weight % (for example, 0.25-5.0 weight % and more particularly 0.25-4 weight %) of a silicone selected from the group consisting of water insoluble organosilicone compounds selected from the group consisting of:
(i) dimethicones, dimethicone derivatives and mixtures of the foregoing having a viscosity in the range of 5-100,000 centipoise (cps), particularly 30-70,000 cps and even more particularly 60,000 cps; for example organosilicone compounds of

Note, that although other surface active compounds with fiber conditioning properties may also be employed, at least in part. Thus, imidazolinium salts and betaines, and such cationic and amphoteric materials as are described in U.S. Pat. No. 4,000,077 may be substituted for at least some of the quaternary ammonium salt, as may be complexes of cationic and anionic surfactants such as have been described in U.S. Pat. Nos. 4,786,422; 4,888,119; and 4,929,367, which are incorporated by reference herein as to the description of these materials.
DETAILED DESCRIPTION OF THE INVENTION
For the anionic materials (also referred to herein as anionic surfactants or anionic detergents), examples include higher (C8-18) alkyl sulfates, higher paraffin sulfonates, higher olefin sulfonates, higher fatty acid monoglyceride sulfates, higher fatty alcohol lower alkoxy (and polyoxy) sulfates, linear higher alkyl benzene sulfonates, and dialkyl sulfosuccinates. The most preferred of these anionic detergents for the examples of shampoos described herein are the higher alkyl sulfates of 10 to 16 carbon atoms and the higher alkyl lower alkoxy sulfates of 10 to 18 carbon atoms (preferably with the higher alkyl thereof being lauryl and with 2 or 3 ethoxy groups per mole). However, such alkyls may be of 10 to 16 carbon atoms and the alkoxy content may be of 1 to 20 per mole, such as 2 to 6 ethoxy
