摘要:
Disclosed are methods for detecting demineralization of a surface of a tooth, comprising a) contacting the tooth of a subject with an orally acceptable, binding composition comprising a binding agent that binds to a demineralized surface of the tooth; b) removing unbound binding compound; c) contacting the tooth with an orally acceptable, detector composition comprising a probe compound that reacts with the binding agent to form a visually detectable reaction product; and d) detecting formation of the reaction product as an indication of the presence or extent of surface demineralization of the tooth. Systems, kits, and compositions for practicing the methods are also provided.
摘要:
A method of measuring the relative rates of release of a target metal ion from two or more samples includes: (i) providing at least two aliquots of a solution including an indicator, the indicator having a colour; (ii) dispersing a sample into each aliquot; and (iii) during step (ii), monitoring the colour of the indicator in situ to determine the rates of release of the target metal ions from the samples relative to one another. Each sample comprises at least one source of the target metal ion. The indicator comprises zincon. The samples are oral care compositions selected from a toothpaste, a tooth gel, and a tooth powder. The target metal ion is selected from the stannous and zinc (II).
摘要:
The present invention relates to oral compositions for identifying plaque comprising a dental disclosing agent composition for revealing the presence of dental plaque in a person's mouth including natural colorants derived from purple carrot.
摘要:
A composition for protecting from ultraviolet radiation is disclosed. The composition comprises a filter and an effectiveness indicator responsive to the reduction of effectiveness protection.
摘要:
A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.
摘要:
A material encapsulation and release system having a first zone (1) containing a first amount of material (2) bound by a first capsule wall (3) and, if desired, a second zone (4) containing a second amount of material (5) bound by a second capsule wall (6), each capsule wall responsive to similar or dissimilar activation means (7) to release the first amount of material (2) in the first zone (1) and the second amount of material (5) in the second zone (4).
摘要:
The invention provides an orally acceptable plaque indicator gel comprising a dye in sufficient concentration to visibly stain plaque upon application, optionally for use in combination with an orally acceptable plaque removal gel comprising an antiplaque agent in sufficient concentration to remove plaque and or kill bacteria upon application, in each case the gel having a specific viscosity permitting efficient application using a pen dispenser, as well as reduced dye or antiplaque agent concentration, together with methods of using the same.
摘要:
A skin care composition with indicating function including a skin care component, a pH indicator and a buffer solution is provided. The skin care composition has a pH value less than or equal to 8. A method of using the skin care composition includes the following. The skin care composition is applied on a skin surface. After the skin care composition is applied on the skin surface for a period of time, the color of the skin care composition changes. When the color of the skin care composition changes, the skin care composition is removed from the skin surface.
摘要:
A composition comprising at least one indicator, at least one light stabilizer, and at least one antioxidant. The composition is useful as a cleanser that provides a usage timer based on color change to indicate to a user that sufficient time has elapsed for cleansing.
摘要:
A composition of matter includes a cationic dye and a solvent, wherein the composition does not have particles that are greater than 25 microns in diameter. The disclosure also describes a method for producing a composition of matter. An ink jet cartridge includes the composition of matter. A device includes a substrate having an image printed thereon with the composition of matter. A method includes using an inkjet printer to print a graphic on a first major surface of a substrate; moistening a user's skin surface; contacting the first major surface of the substrate to the user's moistened skin surface; and removing the substrate from the user's skin surface, thereby leaving a mirror image of the printed graphic on the user's skin surface. Moreover, an art kit includes a first substrate having a graphic printed thereon and a second substrate having a mirror image of the graphic printed thereon.
