Embodiment 1

[0084] Example 1: Ultrasonic bleaching of EDDS formulations

[0085] The above bleaching composition was formulated with a chelating agent comprising 2.0% by weight of the trisodium salt of EDDS. Using the method described above, the bleaching composition was applied to three selected hair switches for five repeated cycles.

Embodiment 2

[0086] Example 2: Ultrasonic Control Bleach Formulation

[0087] The above bleaching composition is prepared by replacing the chelating agent with equivalent weight percent of deionized water. This composition was applied to three additional virgin hair switches for five cycles.

Embodiment 3

[0088] Example 3: Traditional Bleached EDDS Formulation

[0089] The above bleaching composition was formulated with a chelating agent comprising 2.0% by weight of EDDS trisodium salt. Three hair switches were treated and individually wrapped in plastic film and heated at 30°C for 30 minutes. Each switch was then removed from the oven, the film removed, and rinsed with water for one minute. Next, each switch was shampooed and rinsed as described above, but without the use of sonication. This process is applied to each hair switch for five cycles.

Abstract

The invention is the use of a chelating agent with an ultrasonic device for the treatment of hair and other fibers. The treatment device includes an ultrasound generator, a comb device responsive to the generated ultrasonic waves, a reflector for reflecting the incident ultrasonic waves disposed on the distal end of the comb device, and a chelating agent preferably disposed within the treatment device. The treatment device efficaciously dispenses the chelating agent and ultrasonically treats the fiber.

Description

field of invention [0001] The present invention is in the field of treatment of keratinous fibers using ultrasonic devices and chelating agents. Background of the invention [0002] Bleaching and dyeing keratinous fibers such as hair has become increasingly popular. This technique allows one to change the natural color of a fiber into a potentially trendier color, or to hide imperfections present in natural fibers. However, these methods are slow, laborious, inefficient, ineffective topically, and use chemical agents that damage the treated fibers. [0003] In these methods, the desired color is produced by chemically treating a naturally occurring fiber pigment called melanin. As hair grows, melanin is formed in the hair bulb at the root of the hair and deposited into the center of the hair shaft. The hair shaft comprises dead cells that differentiate into a mixture of different forms of the hair protein, keratin, and has two main regions, the epidermal region (outer) an...
