Common Harmful Chemicals in Hair Root Powder & Touch Up
Chemical Name
Why it’s harmful
Talc, a naturally occurring mineral, is commonly used in cosmetics and personal care products for its moisture-absorbing, smoothing, and anti-caking properties. It is also utilized in food products and animal feed. However, some talc may be contaminated with asbestos fibers, which are linked to cancer. This contamination occurs due to the proximity of talc deposits to asbestos mining sites. Health concerns associated with talc include irritation, cancer risks, and potential organ system toxicity.
Octamethylcyclotetrasiloxane is a versatile chemical used in extreme temperature silicone oils, foam suppression in lubricating oils, and in various industries like electronics, construction, cosmetics, and more. It is flammable and very toxic to aquatic life, potentially causing long-lasting harm. Additionally, it is classified as toxic for reproduction category 3, but it is not currently regulated in cosmetics and has not been evaluated by the Scientific Committee on Cosmetology.
Silica, also known as silicon dioxide with the formula SiO2, occurs in many forms that have the same chemical composition but differ in atomic arrangements. These forms are categorized into two groups: crystalline silica (c-silica) and amorphous silica (a-silica). The difference lies in their structure; c-silica has repeating patterns of silicon and oxygen, while a-silica structures are more random. All silica forms are odorless solids that form non-explosive dust when suspended in the air. Additionally, silica can react with other metallic elements and oxides to form silicates.
The study on 1,576 U.S. workers exposed to TiO2 for over a year from 1956 to 1985 showed no increase in lung cancer or chronic respiratory disease, and no cases of pulmonary fibrosis. Cases of pulmonary fibrosis related to TiO2 exposure have been reported, possibly due to silica contamination. There are no listed effects for short-term or long-term exposure. Although NIOSH recognises ultrafine TiO2 as a potential occupational carcinogen, data is insufficient to classify fine TiO2 similarly. Epidemiological studies do not provide clear evidence of lung cancer risks from TiO2 dust exposure.
