Abstract: Compositions, such as lens precursor compositions, and methods for producing lens precursor compositions have been invented. The present methods include forming a premix composition, which can include one or more monomeric components, forming a macromer composition, which includes one or more silicon containing macromers, forming a premix/initiator composition, which can include a photoinitiator, and contacting the premix/initiator composition with the macromer composition to form a polymerizable monomer-containing composition useful in the production of producing silicone hydrogel contact lenses.

Abstract: The present invention relate to a sanitary tampon comprising a compact applicator and a tampon (3) of compressed absorbent material stored within the applicator, the applicator having an inner tube (1) and an outer tube (2) slidably disposed over the inner tube (1). The outer tube (2) has a distal discharge end (4) for insertion into the body of the user. The tampon (3) is solid and substantially cylindrical in shape and is constructed such that at least a part of the body (11) of the tampon (3) adjacent the proximal end (13) sits at an angle to the longitudinal axis of the applicator so that when the inner tube (1) is withdrawn past the proximal end (13) of the tampon (3) to prime the applicator for use, the proximal end (13) of the tampon will urge itself against the inner surface of the outer tube (2) and when the inner tube (1) is pushed back into the outer tube (2) to expel the tampon, the tampon is hindered from re-entering the distal end (6) of the inner tube (1).

Abstract: Derivatives of p-menthane are disclosed having the property of stimulating the cold receptors of the nervous system of the human body to produce a cold sensation and are used for this purpose in a variety of edible and topical preparations.

Abstract: According to the invention physiological cooling activity is imparted to tobacco and tobacco-containing manufactures, e.g. pipe tobacco and cigarettes by incorporating therein certain cold receptor stimulating derivatives of p-menthane, viz: p-menthane-3-carboxylic acid, its salts and certain esters thereof, and p-menthane-3-carboxamide.

Abstract: Compounds are disclosed having a physiological cooling action on the skin. The compositions contain, as the effective ingredient, certain esters of p-menthane 3-carboxylic acid.
