Description

Hair cosmetic composition for electromagnetic wave blocking

The present invention relates to a hair cosmetic composition having a function of blocking electromagnetic waves by using a conductive polymer doped with a dopant. Here the hair cosmetic composition includes products such as shampoo, conditioner, gel, mousse, spray.

The use of electricity, such as electrical equipment or electronic products, inevitably generates electromagnetic waves. In recent years, due to the breakthrough in the field of telecommunications, the use of electric and electronic devices has been rapidly spreading, and the harmfulness of electromagnetic waves has emerged.

Electromagnetic waves are a kind of electromagnetic energy with a wide frequency range ranging from 0 직류 direct current to 10 ²² 감 gamma rays according to frequency, and proceed at a speed of 300,000 km / sec, such as the speed of light. Energy is high.

Electromagnetic waves are composed of electric and magnetic fields, each of which oscillates at right angles to the direction of wave propagation, and the electric and magnetic fields are at right angles to each other.

Electromagnetic waves have a variety of types and shapes depending on the intensity, waveform, etc. as well as frequency. The classification according to the frequency of electromagnetic waves is shown in Table 1.

Light rays are also classified as infrared rays, visible rays, ultraviolet rays, etc. Among them, ultraviolet rays have the shortest wavelength, the strongest energy, and are known to cause skin cancer. DC to ultraviolet rays are called non-electron waves, and X-rays and gamma rays with shorter wavelengths than ultraviolet rays are called ionizing radiation. This ionizing radiation has a very strong energy that can penetrate the human body and cause abnormalities in cellular molecules, leading to abnormalities in genetic factors.

Sources of electromagnetic waves in everyday life include microwave ovens, electric heaters, TV and computer monitors, mobile phones, hair dryers and subways.

Computers have been the target of research on damage caused by electromagnetic waves, and they have been named VDT syndrome, along with research reports that cause vision loss, headache, and muscle aches.

Computer monitors have thousands of volts of high-voltage generators that emit light by colliding accelerated electrons on fluorescently treated screens, producing electromagnetic waves that range from 50 to 90 Hz.

Since the mobile phone uses a microwave of 800 ~ 900MHz, the electromagnetic wave transmitted from the antenna is reported to affect the human body by raising the temperature of the cell to the brain.

Microwave ovens use microwaves in the 2450MHz frequency range to heat food molecules by adding microwaves to food to heat water molecules contained in the food.

As a result of studies on the biological effects of electromagnetic waves generated from electronic devices and electronic products that are commonly used in daily life, electromagnetic waves are reported to be harmful to humans.

All the functions of the human body are controlled by electrical signals. When the human body is exposed to strong electromagnetic waves, it affects the voltage between the cell membranes and changes the movement between the cell membranes such as Na + and K + ions, which affects various hormone secretions. It has been reported to cause changes in human brain activity, heart rate and immune system.

Microwaves also increase the temperature of human tissues, affecting cells such as brain tumor induction, brain cell DHA tissue damage, blood and lymph cancer induction, reproductive organs, and leukocytes.

In order to block electromagnetic waves that are known to be harmful to the human body, fabrics and clothes for electromagnetic wave blocking applications have appeared. Japanese Patent Application Laid-Open No. 01-221549 (Toray, Sep. 5, 1989) relates to electromagnetic wave shielding fabrics and clothes. The fabrics of polyester are treated with alkali and then coated with metal to provide antistatic and electromagnetic wave blocking functions. Given.

British Patent No. 2234857 (published Courtulds PLC, Feb. 13, 1991) relates to fabrics composed of polymers containing activated carbon to reduce the reflection of microwaves, textiles treated with organic solutions such as hydrocarbons, halogenated hydrocarbons. will be.

U.S. Patent No. 5,115,140, published May 19, 1992, discloses a human barrier composition of Electromagnetic Interference (EMR) / Radio Frequency Interference (RFR) / Microwaves (MWR) by coating a copper base. It is about.

Electromagnetic waves have been shown to have a fatal effect on the brain, such as inducing brain tumors and damaging the DHA tissues of brain cells. Upon application, the inventors found that the electromagnetic wave shielding effect was excellent and completed the present invention.

In the present invention, when the content of the conductive polymer is less than 1% by weight, the electromagnetic wave blocking effect is insignificant, and when the content of the conductive polymer is greater than 10% by weight, the content of the conductive polymer is 1 to 10% by weight.

To block electromagnetic waves, simultaneous blocking of electric and magnetic fields is required. The electric field can be blocked by a conductor, and the magnetic field can be blocked by using a metal having a high conductivity (easiness of magnetic field transmission).

The unit of conductivity is generally expressed in S / cm, and divided into insulators, semiconductors, and conductors by this conductivity. Insulator when conductivity is 10 ^-18 S / cm to 10 ^-7 S / cm, semiconductor when semiconductor is 10 ^-7 S / cm to 10 ^-3 S / cm, semiconductor, 10 ^-3 S / cm to 106 S / cm or more Cases are classified as conductors (see Introduction to Physical Polymer Scicnce, LH Sperling, Second Edition, p 567).

Most polymers are insulators, and polyethylene, polyvinyl chloride, and the like are generally used as insulating materials for electric wires.

Polyparaphenylene, polyphenylene sulfide, polythiophene, polypyrrole, polyphenylquinoline, polyaniline, polyselenophene, polystyrene and the like are insulators as conjugated polymers but exhibit electrical conductivity by treatment of dopants.

The dopant used to increase the electrical conductivity at this time is a material that is easy to provide or accept electrons, for example, iodine, bromine, arsenic fluoride (A _S F ₅ ), lithium, potassium, aluminum chloride (AlCl ₃ ) Antimony fluoride (SbF ₅ ) may be used. The electrical conductivity of the doped conductive polymer is shown in Table 2 (see Polymer Chemistry, Malcolm P. Stevens, Second Edition, p 136).
