A hair-treating composition containing a diester or polyester of a naphthalene dicarboxylic acid having compound formula (I) or (II), or mixtures; for imparting gloss and / or hair color stabilization:wherein each R1, same or different, is an alkyl group having 1 to 22 carbon atoms, a diol having the structure HO-R2-OH, or a polyglycol having the structure HO-R3-(-O-R2-)m-OH, wherein R2 and R3, same or different, are each an alkylene group, sight chain or branched, having 1 to 6 carbon atoms, and wherein m and n are each 1 to about 100, or a mixture thereof. These diesters and polyesters of formula (I) or (II) are quite effective in stabilizing the dibenzoylmethane derivative UV-A filter compounds making them more effective, and effective for longer periods of time.

This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, the mixture may be pyrolyzed at high temperatures (e.g., between 500° C. and 1000° C.). The pyrolysis may be conducted for an amount of time at least partially sufficient for production of discrete, identifiable biofuel compounds. Some embodiments involve heating the mixture of catalyst and hydrocarbonaceous material at high rates (e.g., from about 50° C. per second to about 1000° C. per second). The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used; optionally, the catalysts used herein may have high silica to alumina molar ratios. In some instances, the composition fed to the pyrolysis reactor may have a relatively high catalyst to hydrocarbonaceous material mass ratio (e.g., from about 5:1 to about 20:1).

The invention discloses a powdery attapulgite foaming agent. The technical scheme has the following key points: the powdery attapulgite foaming agent is composed of active attapulgite clay, sodium percarbonate, sodium pyrophosphate, lauryl sodium sulfate, sodium polyacrylate and poly-naphthalene formaldehyde sodium sulfonate. The finished product of the powdery attapulgite foaming agent is prepared by stirring, grinding and packaging the ingredients. The powdery attapulgite foaming agent has the advantages that the foaming agent is high in foaming capacity, more in bubbling times and large in unit volume foam production quality, and enables the outer films of foams to have good toughness so as to guarantee the foams not to be easily broken; the foams are good in stability, can exist for a long time without being defoamed, and are fine and smooth; holes generated in a medium are even in sizes; the water secretion quantity is low; and the used medium is good in compatibility, etc. The products produced by the powdery attapulgite foaming agent not only can effectively control the noise pollution, but also have the functions of heat preservation and air purification; and the powdery attapulgite foaming agent is suitable for producing light weight boards, light weight walls and noise reduction products.

A low-foaming cleaning solution and dry particulate formulation which can be diluted with water, deionized water, or mixtures thereof, to form the cleaning solution. The cleaning solution has an alkaline pH, which is preferably from about 8 to about 11.5 and consists essentially of at least one low foaming surfactant in a concentration of from about 0.005% to about 40% w / w of the total solution, at least one active oxygen releasing compound in an amount effective to produce a hydrogen peroxide concentration of from about 0.005% to about 50% w / w of the total solution, at least one builder in a concentration of from about 0.001% to about 50% w / w of the total solution, and at least one diluent selected from the group consisting of water, deionized water, and mixtures thereof. The at least one surfactant is selected from the group consisting of C3-C8 alkane sulfonates, C3-C8 alkyl sulfates, C1-C7 alkyl naphthalene sulfonates, polyoxyethylene / polyoxypropylene block copolymers having a polyoxypropylene molecular weight of from about 1500 to about 8500, of which less than about 30% of the total molecular weight is due to the polyoxyethylene portion, and mixtures thereof. The at least one active oxygen releasing compound is selected from the group consisting of hydrogen peroxide, at least one source of hydrogen peroxide, and mixtures thereof.
