Abstract:
An absorbent article has a skincare composition applied on at least a portion thereof so as to be transferable to the skin of the wearer. The composition is solid at 21° C. and includes at least three constituents, being chosen according to their melting behavior, and characterized, in particular, by the presence of a crystallization accelerator.
Abstract:
Hygiene products such as diapers, tampons, pantyliners and the like are produced using body-compatible substances in the form of nanoparticles having surfaces that have been chemically and/or physically modified. The substances may be oxides, oxide hydrates, hydroxides, halogenides, phosphates, sulfides, nitrides or carbides of aluminum, silicon, alkali metals, alkaline earth metals, or secondary group elements. The surface modification may be carried out using organic compounds such as carboxylic acids, carboxylic acid derivatives, amino acids, hydroxycarboxylic acids, sugar acids, polyglycolic acids, ether carboxylic acids, alkyl halides, or silanes.
Abstract:

Abstract:
A polyolefin-containing material including an internal additive, where the internal additive is a triglyceride according to the structure (T): CH2(OR1)—CH(OR2)—CH2(OR3) (T) where R1, R2 and R3 are, independently of one another, saturated, mono- or poly-olefinically unsaturated acyl groups containing 8 to 24 carbon atoms, the chain lengths of the acyl groups are the same or different, and the polyolefin-containing material exhibits improved softness is provided. A process for the softening finishing of articles including polyolefins is also provided and includes adding a triglyceride to polymer granules including a polyolefin present in an amount of from about 0.1% to about 40% by weight, based on the weight of the granules, and subjecting to further processing to form a fiber or film.
