Patent number: 11679070Abstract: The present disclosure relates to methods for treating hair with lactones. The lactones form a covalent thio-ester bond with free thiols groups on chemically treated hair, and thereby impart a “repairing” or “conditioning” effect to the hair, for example, by making the hair more hydrophobic. Typically, after hair has been treated with a composition comprising one or more reducing agents that reduce disulfide bonds of hair to free thiols, a composition comprising one or more lactones is applied to the hair and the one or more lactones react with the free thiols to form a covalent thio-ester bond. Treatment with the lactones prevents reversion of the repaired bonds to their free thiol state after a single application.Type: GrantFiled: May 12, 2016Date of Patent: June 20, 2023Assignee: L'OREALInventors: Andrea Elsen, Charles Shaw, Nghi Van Nguyen, Jim Singer

Patent number: 6860273Abstract: A zone or plug of porous adsorbent material, primarily activated carbon, is placed in the tobacco rod of a cigarette a short distance from the lighting end thereof. The amount of activated carbon is sufficient for effective removal of volatile smoke constituents while allowing the cigarette to burn continuously. The activated carbon traps volatile smoke constituents in close proximity to the burning coal in the first puffs of the cigarette. As the cigarette continues to burn, the burning coal consumes the activated carbon. The adsorbed smoke constituents are effectively removed without releasing them back into the mainstream smoke. Following the consumption of the activated carbon in the tobacco rod, the cigarette is unchanged from a cigarette of conventional design.Type: GrantFiled: October 25, 2002Date of Patent: March 1, 2005Assignee: Philip Morris IncorporatedInventor: Charles E. Thomas, Jr.

Publication number: 20040016436Abstract: A surface-modified adsorbent and a process for making a surface-modified adsorbent are provided. The process involves providing an adsorbent and a non-volatile organic compound to a vessel, adjusting the temperature and/or pressure to provide supercritical conditions for a supercritical fluid, and introducing the supercritical fluid into the vessel. The supercritical fluid dissolves the non-volatile organic compound, and impregnates the adsorbent with the non-volatile organic compound. The surface-modified adsorbent can be used, for example, in cut filler compositions, cigarette filters, and smoking articles. Methods for making cigarette filters, cigarettes and for smoking a cigarette comprising the surface-modified adsorbent are also provided. The surface-modified adsorbents can be used to remove one or more selected components from mainstream smoke, without removing other components, such as those that contribute to flavor.Type: ApplicationFiled: July 26, 2002Publication date: January 29, 2004Inventor: Charles Thomas

Publication number: 20030098030Abstract: A cigarette filter that includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter consists of a fibrous filter plug located at the mouth-end of the cigarette, a section containing a selective adsorbent material, and a section containing a general adsorbent material. The selective adsorbent material, such as a phenol-formaldehyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups, removes specific smoke constituents from the tobacco smoke. The general adsorbent material, such as activated charcoal, is preferably capable of adsorbing a range of chemical compounds without a high degree of specificity. Structurally, the fibrous filter plug, the selective adsorbent section, and the general adsorbent section are co-axially aligned in tandem.Type: ApplicationFiled: June 24, 2002Publication date: May 29, 2003Applicant: Brown & Williamson Tobacco CorporationInventors: James N.

Publication number: 20020166563Abstract: A cigarette comprises a tobacco rod and a multi-component filter comprising a bed of adsorbent and a flavor-releasing filter segment located downstream of the bed of adsorbent. In the preferred embodiment, the adsorbent is also flavor-bearing and comprises high surface area, activated carbon. As mainstream smoke is drawn through the upstream portion of the filter, gas phase smoke constituents are removed and flavor is released from the adsorbent bed. Thereafter additional flavor is released into the mainstream smoke as it passes through the flavor-releasing filter segment. Ventilation is provided to limit the amount of tobacco being combusted during each puff and is arranged at a location spaced downstream from the adsorbent bed to lower mainstream smoke velocity through the adsorbent bed.Type: ApplicationFiled: February 22, 2002Publication date: November 14, 2002Inventors: Richard Jupe, Ronald William Dwyer, Don Earl Laslie, Arlington L.

Patent number: 6006757Abstract: A cigarette holder completely encloses the lit end of a cigarette providing purification for both sidestream smoke and mainstream smoke. It has two concentric tubes with the lit cigarette placed in the inner tube and purifying agent placed in the volume between the inner tube and the outer tube. A chimney effect is produced wherein air flows through an air port past the lit cigarette to keep it burning. The sidestream smoke passes through the purifying agent and is discharged into the environment. The filter tip of the lit cigarette extends through a mouthpiece and the smoker exhales smoke through openings in the same mouthpiece. The mainstream smoke passes through the same purifying agent, in a direction opposite to the flow of the sidestream smoke, and is then discharged into the environment.Type: GrantFiled: May 14, 1998Date of Patent: December 28, 1999Inventor: Edward Lichtenberg
