A personal care 100% plant derived, biodegradable solid granules that sustain beneficial essential oils, and or plant/herbal extracts and emulsify in water to create an emulsified therapeutic solution is disclosed. This invention improves over existing liquids in that its solid granule form is completely plant derived and biodegradable and can sustain essential oils and antioxidants without the requirement of chemical preservatives, and can be packaged in eco-friendly water soluble film and compostable paper. It improves over existing solid forms in that it is a 100% water soluble granule that emulsifies easily in water to form an easy to use liquid product.

The present subject matter relates to light-activatable polymeric nanoparticles (NPs) for the transportation and release of an active substance, methods for obtain said particles and their uses. A light-activatable nanoparticle for the transportation and release of an active substance, comprising a polycation preferably a polimer polycation, a polyanion and a light-sensitive photochrome attached to the polycation or the polyanion, wherein said photochrome is hydrophobic and suitable to photo-cleave when activated by an irradiation source, generating a negative charge and releasing the active substance. Light-activatable. The disclosure subject matter shows that NPs are a highly efficient drug delivery system to primary leukemic cells based on opto-nanomedicine system. Therefore, the present disclosure is useful for remote control in the release of biomolecules with spatio-temporal resolution with applications in the areas of general therapeutic and regenerative medicine applications.

The invention relates to nano-sized complexes formed by associating amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant. The amphiphilic polymer surfactants can form nano-sized assemblies in aqueous solution, serving as a nano dispersant preventing ACP and/or ACFP from aggregation, and as a nano carrier associating or attaching ACP and/or ACFP, stabilizing ACP and/or ACFP against the conversion to a crystalline form as well, thus maintaining calcium and phosphate/and fluoride ions in a bioavailable state for dental re-mineralization and prevention of dental caries, dental calculus and dental hyper-sensitivity. A method for the nano-sized complex preparation and compositions comprising the nano-sized complexes are also provided.

An aqueous oral care fluoride treatment composition, a method of providing fluoride to a patients tooth surface, and a method of reducing the incidence of dental caries, wherein the composition includes: 0.5 wt-% to 4.8 wt-% of a water-soluble cationic N-containing polymer; a pharmaceutically acceptable buffer; 1.0 wt-% to 2.5 wt-% of sodium fluoride; and at least 60 wt-% water; wherein the weight percentages are based on the total weight of the aqueous composition.

Disclosed are compositions including dihydroxyalkyl substituted polygalactomannan, and the optional further substitution of such with cationic and/or hydrophobic moieties. Method of making such compositions is also disclosed as well as the use of such compositions in industrial applications, fabric laundering, and personal and household care.

The present invention provides a composition containing component (A): a compound represented by the formula (1)

##STR00001##

wherein each symbol is as described in the DESCRIPTION, or a salt thereof and component (B): a cationic surfactant, which is superior in the usability during rinsing, which makes the hair surface after treatment smooth and free of dry feeling, provides a uniform touch feeling from the root of the hair to the tip thereof, and can be utilized as an aqueous cosmetic.

Disclosed are compositions for treating and conditioning keratinous substrates, comprising a cationic agent comprising quaternary ammonium compounds; a modified starch; silane compounds, a cationic vinylpyrrolidone polymer and water. Also disclosed are methods treating and conditioning keratinous substrates using the composition.

The present disclosure relates to methods for inhibiting color fading in hair and for improving the color durability and stability of artificial color of hair. The methods entail forming a layer-by-layer (LbL) film on hair, and optionally forming a cationic surface layer on the LbL film. The LbL film is formed by applying a cationic silane layer on the hair and subsequently applying an anionic polymer layer on the cationic silane. Multiple cationic silane layers and anionic polymer layers can sequentially be added as desired. Finally, the LbL film may comprise a cationic surface layer.
