  • Patent number: 11111339
    Abstract: The present invention relates to a crosslinked polyacrylate salt, which has been neutralized by two types of amines: (1) amine groups attached to the polymer backbone of an aminosilicone and (2) water soluble organic amines. The compositions of the present invention can readily swell in water, displaying enhanced thickening, emulsifying, dispersing and producing film with water resistance compared to acrylate based thickener alone. The compositions can be used to formulate a wide variety of ingredients, such as, for example, fatty substances, humectants, solid particles, silicones, organic or inorganic sunscreens, without the need of further neutralizing agents, dispersants or emulsifiers.
