Patent CA-2352827-A1 (CA)
Inventor: FU DIANKUI
IPC: C09K8/86
Filed: 1999-11-30
Abstract: L'invention concerne des liquides comprenant seulement des anions et des cations (<= fluides ioniques >=) utilisés en tant que nouveaux composants de fluides (et techniques faisant appel à ces fluides) pour la stimulation de puits d'hydrocarbures. Ces fluides sont utiles en particulier pour l'acidification matricielle. La formation des liquides ioniques de l'invention est hautement exothermique. Ainsi, par exemple, on peut utiliser la chaleur dégagée pour faire fondre le fluide de forage exempt d'eau dans la zone située à proximité du puits de la formation. De plus, la mise en réaction des liquides ioniques avec de l'eau permet de produire de l'acide. On peut utiliser cet acide, par exemple, pour stimuler une formation, au moyen de techniques d'acidification matricielle conventionnelles ou d'acidification avec fracturation. En outre, certains types préférés des liquides ioniques de l'invention sont des solvants hautement stables, qui peuvent être utilisés en tant que fluides porteurs destinés à des super acides réactifs (par exemple, SbF¿5? + HF), dans le cadre d'une acidification matricielle.

Title: Formulation and method for smoothing and waving multi-textured hair
Inventor: HARRIS PAMELA
IPC: A45D7/04
Filed: 2000-05-05
Abstract: The present invention provides a process by which smoothness, body and a permanent wave pattern can be imparted to multi-textured hair of all types, from hair having an excessively thightly curled appearance, such as Negroid hair, to hair having a straight appearance, such as Caucasian hair, with substantially less damage to the hair. The process of the present invention uniquely combines the use of two hair structure altering chemicals -- an alkaline hydroxide (such as sodium hydroxide) and a thioglycolate reducing agent (preferably ammonium thioglycolate) -- to harmoniously bring about a desired wave pattern in the hair. Using the Wave Balance Scale (a hair reference scale) of the present invention, a sodium hydroxide formulation is chosen based on the type and natural curl level of the hair. The sodium hydroxide formulation is applied to the hair for a time sufficient to relax the natural curl in the hair by breaking some of the sulfide bonds in the hair. Then, after rinsing but prior to any neutralization, the ammonium thioglycolate formulation is applied to the hair and the hair is placed on curling rods for a time sufficient to rearrange the wave pattern of the relaxed hair. The hair is then rinsed and neutralized, while still rodded, for a time sufficient to lock in the new wave pattern by reforming the sulfide bond linkages. After neutralization, the hair can be shampooed, conditioned and styled either curly or straight as desired by the patron.
