The invention relates to concentrated liquid cleansing compositions in lamellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. The use of a specific ratio of synthetic anionic surfactant(s) and co-surfactant(s) to fatty acid(s) in a structured liquid product was found to improve lather production by moderating or eliminating the increase in viscosity upon dilution. In a further embodiment, specific small hydrophobic molecules were found to improve freeze/thaw stability and thereby cause the inventive composition to maintain noticeable moisturization signals.

The invention provides a lithium ion battery anode material adopting an in-situ developed heterogeneous core-shell structure and a preparation method of the material. The lithium ion battery anode material is a composite with a lithium-rich lamellar phase material as a core layer and a heterogeneous spinel phase generated on the surface of the core layer in an in-situ manner. The lithium ion battery anode material is prepared in the steps as follows the lithium-rich lamellar phase material containing Ni, Mn and M is prepared from carbonate or hydroxides with a coprecipitation method and then dispersed in a mixed salt solution of Ni, Mn and M, the amount-of-substance ratio of Ni to Mn to M in the solution is the same with that in the lithium-rich lamellar phase material, the coprecipitation reaction is performed again, and the mixed metal carbonate (or metal hydroxide) coated lithium-rich lamellar phase material is obtained, the lithium-rich lamellar phase material is sintered at the high temperature in the absence of a Li source, and the lithium ion battery anode material adopting the in-situ developed heterogeneous core-shell structure can be obtained. The lithium ion battery anode material adopting the in-situ developed heterogeneous core-shell structure has the advantages as follows the shell layer coats the core layer in a uniform, complete and thickness-controllable manner, no obvious phase boundaries exist between the core layer and the shell layer, and the electrochemical performance of the material is improved.

Unsaturated fatty alcohol alkoxylates, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol alkoxylate is made by reducing a metathesis-derived monounsaturated alkyl ester, followed by alkoxylation of the resulting monounsaturated alcohol. Microscopy reveals that the monounsaturated alkoxylates have isotropic and lamellar phases over a wider range of actives levels compared with their saturated analogs. This attribute expands formulating latitude for many end-use applications. The unsaturated fatty alcohol alkoxylates are valuable in, for example, agricultural solvents, nonionic emulsifiers for agricultural compositions, hard surface cleaners, laundry detergents, specialty foams, additives or surfactants for paints or coatings, and surfactant compositions for enhanced oil recovery.
