Abstract: Methods of cleansing skin comprise the steps of contacting the skin with a cleansing compositions comprising a fatty ester in combination with a lipid, and either rinsing the composition from the skin with water or wiping the composition from the skin with a dry or damp substrate. The cleansing compositions can comprise at least 8%, by weight of the composition, of fatty ester and/or further comprise a nonionic surfactant and less than about 50%, by weight of the composition, of an alcohol solvent such as ethanol, isopropanol, or mixtures thereof. The methods and compositions provide skin cleansing and hydration benefits.

Abstract: A rinsable personal care composition comprises (a) 0 to 75 weight percent of a surfactant; (b) 0.01 to 99 weight percent of a skin benefit agent comprising a high modulus lipid and an ester; and (c) 0 to 99 weight percent water.

Abstract: A disposable nonwoven mitt is adapted to be retained on a user's finger(s) during use. The disposable nonwoven mitt can be associated with a personal care composition. The disposable, nonwoven mitts can be useful for cleansing and/or treating the skin, hair or other similar keratin-containing surfaces. These mitts can be used by the consumer by either wetting a substantially dry mitt with water and then rubbing the mitt against the skin, hair or other similar keratin-containing surfaces, or taking a wet, disposable, nonwoven mitt and rubbing against the skin, hair or other similar keratin-containing surfaces or taking a moist, disposable, nonwoven mitt and rubbing against the skin, hair or other similar keratin-containing surfaces.

Abstract: A portable, sequential air sampler having an easily transportable housing containing therein a plurality of interrelated components which allow the air sampler to operate by either battery or "line" power as well as maintain the flow rate through the sampling media substantially constant. The components include a vacuum pump and rotary valve which are capable of sequentially drawing air through the sampling media. In addition, a flow rate control system is operably connected to the vacuum pump in order to maintain the substantially constant flow rate through the sampling media. The air sampler can vary initiation of the sampling operation from 1-999 minutes while varying the sequence of sampling from 1-99 minutes, and, yet, maintai substantially constant air flow throughout the air sampling procedure.

Abstract: The liquid nitrogen level in a flask is controlled by the degree of immersion of two sensing coils of copper wire in the liquid nitrogen activating a solid state switching circuit which controls a liquid nitrogen inlet flow valve. Manual override and sensor fault indication is provided.
