The present invention relates generally to detergent compositions and, more specifically, to detergent compositions containing a branched surfactant.

The present disclosure relates to a polymerizable surfactant with reducibility and a preparation method thereof. The acid anhydride is reacted with a long-chain fatty alcohol to obtain an intermediate of an anhydride monoester, and then the obtained intermediate is reacted with the hydrochloride of dimethylaminohalogenated alkane, and a polymerizable surfactant with reducibility is obtained by post-processing. The polymerizable surfactant can not only play a role as a reactive emulsifier and copolymerize with monomers to obtain a soap-free emulsion, but also form a redox initiation system with peroxide, and conduct redox emulsion polymerization at room temperature. The soap-free emulsion synthesized by the polymerizable surfactant synthesized can greatly reduce the energy consumption in production, and can carry out one-step emulsion polymerization at normal temperature or low temperature to obtain an environment-friendly emulsion with a branched structure, thereby obtaining coatings with excellent water resistance, weather resistance, and impact resistance.

The present invention relates to variants of a parent lipase which has lipase activity and comprise one or more substitutions corresponding to G23S, D27N, A40I, F51I,L, E56R, D57N, V60E,K, K98I, N101D, R118F, G163S, T231R, N233R, Y220F, T244E, and P256T using SEQ ID NO: 2 for numbering. The present invention also relates to compositions or microcapsule compositions comprising a lipase variant of the invention and to liquid products comprising a microcapsule composition of the invention as well as the use of said microcapsule composition for stabilizing lipase variants of the invention.

A cleansing composition comprising an aqueous solution of an anionic polymer, a nonionic polymer and a system of surfactants. Solutions as described herein comprise two distinct aqueous phases having different compositions and density. Further methods of use are also disclosed.

A cleaning composition includes at least two anionic surfactants, an ionic agent, a nonionic surfactant and a fragrance. The at least two anionic surfactants include a linear alkylbenzene sulfonate (LAS) and a sodium lauryl ether sulfate (SLES). The LAS and the SLES are present in the cleaning composition in a total amount combined of about 1%-2% by weight. A weight ratio of LAS:SLES is about 3:1 to about 1:1 or about 6:1 to about 4:1. The ionic agent is present in the cleaning composition in an amount of about 0.01% to about 1% by weight. The nonionic surfactant is present in the cleaning composition in an amount of at least about 0.45% by weight.

The need for a light duty maintenance cleaning spray for hard surfaces, which result in less over-spray during application, especially when using spray applicators which provide large coverage angles, and provides more uniform coverage, especially on inclined surfaces, is met when the spray composition is formulated with low surfactant levels and thickener, and is applied as spray droplets having the desired particle size.

Disclosed are staged emulsion polymers comprising a crosslinked first stage polymer and a subsequently polymerized linear or slightly crosslinked second stage polymer segment. The staged emulsion polymers possess a dual activation mechanism and provide desirable rheological, clarity, and aesthetic properties in aqueous and aqueous surfactant containing compositions.
