A new method and a system for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The device includes a dispensing unit for the composition, a distal end of which is adapted to apply the composition onto teeth or gums. The device further includes an electrode system having first and second electrodes, the first electrode adapted to be held against the composition at a location at or near teeth or gums, and the second electrode adapted to be held against the composition at a location away from teeth or gums. The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the first and second electrodes.

Disclosed is an encapsulated composition comprising at least one perfume and/or cosmetic ingredient that is entrapped in a matrix. The matrix comprises a starch and a hemicellulose.

The present invention refers to the oral and dental health care field since it refers to a modified and improved dental floss material aimed at preventing the onset and progression of dental caries and periodontal disease.

The invention relates to a new process for the manufacturing of chitin derivatives, in particular of nanofibrillary chitin, sustainable from the industrial implementation point of view and suitable to produce chitin derivatives having improved properties. The invention further relates to chitin derivatives obtainable with such method. The invention further relates to the uses of such derivatives which comprise for example the formulation of pastes and aqueous gels useful for the topic applications on skin, the manufacturing of materials of biomedical interest, as well as the deposition of chitin nanofibrils on coating surfaces or the incorporation of the same inside articles such as, for example, hygiene sanitary products.

A composite particle includes a core particle having a pore and fine fibers inseparably bonded to a surface of the core particle. The fine fibers are at least either cellulose nanofibers or chitin nanofibers.

A compound composition with anti-oxidation and anti-aging effects and preparation method and application thereof we disclosed. 5-8 kinds of traditional Chinese medicine extracts from separate extraction of Panax ginseng C. A. Meyer, Poria, Rehmannia glutinosa, Cistanche deserticola Ma, Salviae Miltiorrhizae, Codonopsis Radix, Persicae Semen and Ophiopogon japonicus (Linn.f.) Ker-Gawl. are compounded with chitooligosaccharide to prepare the compound composition with anti-oxidation and anti-aging effects. The compound composition has no toxic side effects, is easy to be absorbed, and can be used for delaying aging, repairing DNA damage and anti-oxidation damage, and can also reduce the risk of geriatric diseases. Moreover, the compound composition can be used as a raw material of dietary supplement or health food to improve telomerase content and delay aging. Therefore, the compound composition is suitable for promotion and application.

Disclosed are microcapsule compositions and their preparation methods. The microcapsule composition has a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material selected from the group consisting of a fragrance, cosmetic active, malodor counteractant, and combinations thereof. The microcapsule wall is formed of a polymeric network comprising of at least three moieties: (i) a first moiety derived from a chitosan, (ii) a second moiety derived from a polyisocyanate, and (iii) a third moiety derived from a polyphenol. Also disclosed are consumer products contain such a microcapsule composition.

Disclosed are microcapsules each having a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material and the microcapsule wall contains hydroxyethyl cellulose moieties. Also disclosed are preparation method and consumer products containing the microcapsules.

A biodegradable single-phase cohesive hydrogel includes a homogenous mixture of 2 to 5 identical or different polymers interpenetrating each other in a single phase, wherein the polymers are independently crosslinked prior to interpenetration by mixing, and the crosslinked polymers are insoluble in water and miscible with each other.

Disclosed is a consumer product comprising a plurality of microcapsules dispersed in a dispersing medium. The microcapsules comprise a core and a shell around the core. The core comprises at least one functional material. The shells of the microcapsules are coated with chitosan. The dispersing medium comprises additional free chitosan. Disclosed is also a method for making such a consumer product, a method for enhancing the deposition and rinse resistance of a plurality of microcapsules dispersed in a dispersing medium and a use of chitosan for enhancing the deposition and rinse resistance of a plurality of microcapsules dispersed in a dispersing medium.
