D1681-92(1997) Standard Test Method for Synthetic Anionic Active Ingredient in Detergents by Cationic Titration ... (387 words)
	1.1 Direct titration of an anionic surfactant with a standardized cationic reagent is a simple and convenient method for the quantitative determination of the content of active ingredient.
	The relationship between anionic and cationic agents is not always stoichiometric, and for maximum accuracy the anionic type of interest should first be characterized and then used to standardize the cationic reagent.
	The anionic surfactants characterized in accordance with Sections 16 to 22 should be the sodium salt and not amine, ammonium, or potassium salts.

CiteULike: Effect of anionic polymers on the release of propranolol hydrochloride from matrix tablets (371 words)
	Anionic polymers, namely Eudragit S, Eudragit L 100-55, and sodium carboxymethylcellulose, were incorporated into hydroxypropylmethylcellulose (HPMC K100M) to modify the drug release from HPMC matrices.
	The effects of changing the ratio of HPMC to anionic polymers were examined in water and in media with different pH.
	The drug release was controlled with the type of anionic polymer and the interaction between propranolol hydrochloride and anionic polymers.
