摘要:
Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, and oral cavity surfaces. Peptide-based body surface coloring reagents, preferably tooth coloring reagents, are formed by coupling a tooth binding peptide to a pigment binding peptide, either directly or through a spacer. The peptide-based body coloring reagents may be used in conjunction with pigments to color body surfaces.

Methods are provided for enhancing the longevity of the binding of various benefit agents to hair and skin. Applications of traditional and non-traditional colorants and conditioners to hair and skin are amended with compositions of hair or skin-binding peptides respectively. The presence of the hair or skin-binding peptide compositions act to increase the longevity of the applied colorant or conditioner on the hair or skin.
摘要:
Peptides having affinity for a body surface are provided. The peptides comprise a body surface-binding peptide block and at least one charged, terminal peptide block. These peptides have enhanced affinity for body surfaces and deposit more rapidly onto body surfaces than peptides lacking the charged terminal groups. The peptides are used to deliver and/or to seal benefit agents to body surfaces, thereby providing enhanced durability.
摘要:
Peptide-based antiacne reagents, formed by coupling a skin-binding peptide with an antiacne agent, are described. The skin-binding peptide portion of the peptide-based antiacne reagent binds strongly to the skin, thus keeping the antiacne agent coupled to the skin for a long lasting effect. Skin care compositions comprising the peptide-based antiacne reagents are also provided as well as a method of treating or preventing skin acne.
摘要:
Peptides have been identified that bind with high affinity to common ink pigments and to various print media, including paper and fabrics. These peptides were used to prepare diblock and triblock dispersants for coating applications, including ink jet printing, and diblock polymers for treating paper and fabrics. The diblock dispersants consist of a pigment-binding peptide coupled to a hydrophilic linker, a pigment-binding peptide coupled to a print medium-binding peptide or a print medium-binding peptide coupled to a hydrophobic linker. The diblock polymers consist of a print medium-binding peptide coupled to a hydrophilic linker or a benefit agent. The triblock dispersants consist of a pigment-binding peptide coupled to a hydrophilic linker, which is coupled to a print medium-binding peptide.
摘要:
A process for enzymatic preparation of a highly linear poly(α 1, 3 glucan) from sucrose is disclosed. The glucosyltransferase enzyme (gtfJ) from Streptococcus salivarius is used to convert sucrose to a highly linear poly(α 1, 3 glucan) in high titers. Hydrolyzed poly(α 1, 3 glucan) is used as the primer for the gtfJ enzyme reaction resulting in the formation of highly linear poly(α 1, 3 glucan).
摘要:
Peptide-based coloring reagents are described in which a body surface-binding peptide is covalently attached to a pigment, the surface of which is coated with a layer containing at least 3 atom percent of silicon. The peptide-based coloring reagents are useful for coloring body surfaces such as hair, skin, nails, and teeth.
