This invention relates to cationically derivatized polycalactomannans obtained from Cassia tora and Cassia obtusifolia and to their use in personal care, household care and institutional care compositions. The cationically derivatized galactomannan polymers can be employed as thickeners, stabilizers, emulsifiers, spreading aids and carriers for enhancing the efficacy, deposition and delivery of chemically and physiologically active ingredients. In addition, these polymers are useful for improving the psychosensory and aesthetic properties of cosmetic formulations, in which they are included.

Patterned self-warming wipe substrates
US Patent 7924142
Publication date: April 12, 2011
Assignee: Kimberly-Clark Worldwide Inc.

This patent relates to wiping substrates such as wet wipes and dry wipes that include a thermal grill utilized to deliver a warming sensation. In one aspect, disposed on at least one structural layer of the wipe substrate is a thermal grill that includes an alternating pattern of thermally active areas and secondary areas that provide a feeling of warmth to a user. The thermally active portions of the wipe include a temperature change substance that, when in liquid communication with an activation agent, is adapted to provide a temperature change of at least 5°C from the temperature of the secondary portion. By providing a thermal grill with thermally active portions, the entire wipe gives the user a warming sensation.

Transdermal therapeutic system
WIPO Patent Application WO/2011/042913
Publication date: April 14, 2011
Inventor(s): Venkata Yedida and Jagannath Surya

According to the inventors of this patent, it has been a long felt need to develop transdermal systems, particularly in patch form, that are economical, practical and patient-friendly to use that do not create cosmetic problems such as low adhesiveness, low tack, viscosity, drug reactivity with the skin, uneven drug delivery, etc. The present invention is said to not only overcome such disadvantages, but also is reportedly easier to manufacture and use.
