Abstract: Applicators, container assemblies, kits, and methods for delivery of controlled, defined doses of cosmetic compositions to an individual's skin, hair, or other body part. An applicator includes a head that is slidably affixed to a shaft. The shaft includes a piston that is slidably positioned within the head. The head also includes a bias member that biases the head toward a distal position relative to the piston. As the bias member is overcome, the head slides down the shaft and the piston enters the head toward a deeper position within the head to displace and discharge the cosmetic from the interior of the head through an aperture of the head and onto the portion of the body of the individual. The applicator can be used for delivery of defined dosages of a variety of cosmetic compositions, including compositions with a relatively higher viscosity.

Abstract: The present invention relates to a method for selective disclosure of confidential data of a first user to a second user of a blockchain (450). The first user is equipped with a deterministic hierarchical key portfolio (410) and selects a leaf of the tree of the portfolio as an emitter account. A secret key is derived from the chain code of this emitter account and the data to be disclosed are encrypted using this secret key. The first user transmits, by means of a first transaction, the data encrypted in this manner to a smart contract (430) which stores them in the blockchain. It transmits by means of a second transaction an access credit to the smart contract which stores it in connection with the pair formed by the emitter account of the first user and the receiver account of the second user. The second user transmits a third transaction to the smart contract from its receiver account (420).
