Patent number: 10450536Abstract: The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ?3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.Type: GrantFiled: January 9, 2019Date of Patent: October 22, 2019Assignee: The Clorox CompanyInventors: Evan Rumberger, Marisa Macnaughtan, William L.

Patent number: 10098503Abstract: A combustible charcoal igniting device may include first elongate grid members generally parallel to one another when the device is in an uncollapsed configuration and second elongate grid members generally parallel to one another and transverse relative to the first elongate grid members when the device is in the uncollapsed configuration. The first and second elongate grid members define chimney cells on or above which charcoal briquets may be placed for ignition. The elongate grid members may comprise a combustible material that can be ignited and that will continue to bum, igniting charcoal briquets placed on the chimney cells. The first elongate grid members may include creases that align with one another, so that the device is collapsible from opposed sides towards a crease line defined by the creases to reduce the length of the device when in a collapsed configuration.Type: GrantFiled: June 7, 2017Date of Patent: October 16, 2018Assignee: The Clorox CompanyInventors: Richard J.
