Abstract: Method of evaluating a product by applying a substance to the surface of an artificial substrate to form a substance-coated surface and performing an analysis of the substance-coated surface. The surface of the substrate may have one or more of the following properties: a total surface energy of from about 15 mJ/m2 to about 50 mJ/m2, a polar component of the total surface energy of from about 0 mJ/m2 to about 15 mJ/m2, and a zeta-potential at a pH of about 5.0 of from about ?30 mV to about 30 mV.

Abstract: In one embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of providing a nonwoven mimic and performing an act on the mimic as may be performed on keratinous tissue. The nonwoven mimic has a surface energy representative of keratinous tissue. In another embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of: providing a mimic comprising from about 60% or greater rayon, from about 40% or less polyester, and a surface energy representative of keratinous tissue; and performing an act on the mimic as may be performed on keratinous tissue. The mimic is preferably a nonwoven mimic.

Abstract: Method of product evaluation comprising the steps of applying at least one substance to a surface of an artificial substrate to form a substance-coated surface, wherein the substrate surface demonstrates at least one physical property selected from the group consisting of a total surface energy of from about 15 mJ/m2 to about 50 mJ/m2, a polar component of the total surface energy of from about 0 mJ/m2 to about 15 mJ/m2, a zeta-potential at a pH of about 5.0 of from about ?30 mV to about 30 mV, and combinations thereof, and performing at least one analysis of the substance-coated surface.

Abstract: A process for preparing liquid personal cleansing compositions which provides enhanced perfume deposition on the skin and which provides increased on-skin fragrance longevity. The liquid personal cleansing compositions contain from about 0.01% to about 5% of a cationic polymer; from about 1% to about 80% of an anionic surfactant; from about 0.01% to about 5% of a volatile perfume; and water. The ratio of the cationic polymer to the anionic surfactant ranges from about 1:100 to about 1:2. The process involves first forming a premix comprising the cationic polymer, the volatile perfume and water, and then adding the premix to a personal cleansing base composition which comprises anionic surfactant and water.

Abstract: Disclosed are liquid personal cleansing compositions comprising a specific surfactant component comprising an ethoxylated alkyl sulfate surfactant having from about 1 to about 8 moles of ethoxylation and an amphoteric surfactant, a select soluble cellulosic cationic organic polymer, and a volatile perfume.

Abstract: Liquid personal cleansing compositions which provide enhanced perfume deposition on the skin and which provide increased on-skin fragrance longevity. The liquid personal cleansing compositions contain from about 0.5% to about 5% of a cationic material, from about 1% to about 80% of an anionic surfactant, from about 0.01 to about 5% of a volatile perfume, and water. The ratio of cationic polymer to the anionic surfactant ranges from about 1:15 to about 1:5.

Abstract: Personal cleansing bar compositions which contain a fragrance-releasing complex and a bar carrier. The fragrance-releasing complex contains a hydrophilic inorganic porous fragrance carrier and a fragrance impregnated within the fragrance carrier. The ratio of the fragrance:fragrance carrier ranges from about 5:1 to about 1:10.

Abstract: Fabric conditioning articles comprising a receptacle releasably containing a pH control agent or electrolyte, and fabric conditioning particles which have a coating of an agent which is insolubilized/made indispersible by the pH control agent or electrolyte. The pH control agent or electrolyte in such articles being separated from the fabric conditioning particles. Methods of using the articles are also provided.

Abstract: Fabric conditioning articles comprising a receptacle releasably containing an agent for making an inner receptacle water insoluble/indispersible which is normally water soluble/dispersible, the inner receptacle containing a fabric conditioning composition. Methods of using the conditioning articles are also provided.
