Dangerous cosmetics: deodorants

Assumptions: in the 60s as a result of experiments conducted on rabbits, the researchers concluded that aluminum, which is part of the antiperspirant causes damage to the nerve cells. After analyzing the effects of aluminum on the nerve cells, they hypothesized that aluminum getting into the human body can be one of the reasons for the emergence and development of Alzheimer's disease. Also, there were many rumors that antiperspirants can cause breast cancer Breast Cancer: Myths and Facts Since they clog the sweat glands and block toxins from the body. In 2004, we published the results of studies of parabens, which are widely used in cosmetics as a preservative. It was found that certain parabens are linked to breast cancer and the reason for it may be tools such as deodorants or antiperspirants, which are usually applied in the armpit area.

Facts: Although the results of individual studies, one hundred percent proof that aluminum is implicated in the emergence or worsening of Alzheimer's disease, to date there. The theory of the accumulation of toxins due to falling aluminum body is not confirmed.

Sweating is one of the tools for monitoring the temperature of our body. The human body gets rid of toxins, through the allocation of urine and excrement, and metabolic processes in the liver. The problem of investigating the influence of the parabens is that they can mimic the body's estrogen hormone, and breast tissue cells, including cancer, under the influence of estrogen tend to multiply. However, it should be understood that parabens have extremely weak estrogenic nature, and in the quantities in which they are contained in cosmetics, pose no threat to human health. Accordingly, the parabens, which are part of shampoos, moisturizers and cleansers, perfectly safe.

Analysis of the results of recent studies have shown that in fact the use of antiperspirants is not related to an increase in the risk of breast cancer. To date, the vast majority of deodorants and antiperspirants generally contain parabens, their presence can be detected in a roll-on deodorant, water-based, but not in the spray or solid antiperspirant.

Perfumery

Assumptions: widely used in industry, including cosmetics, phthalates are often added to perfumes to increase their shelf life and use. Some studies have shown that exposure to phthalates (or salts of phthalic acid esters) causes male reproductive disorders and animal males. Experts examined 379 men suffering from infertility, and based on the information came to the conclusion that they are all in varying degrees of contact with phthalates, which led to a decrease in sperm quality.

The perfumes allocate another component to the unreliable reputation - a synthetic musk fragrances, in the chemical sense is slightly alkaline compounds that includes a part of many flavors. Some types of components have been found in breast milk and human adipose tissue, indicating that the ability of these elements to penetrate the skin. Animal experiments have revealed the ability of some types of musk ingredients in a certain way affect the endocrine and nervous systems, and people provoke dermatitis, and increased sensitivity to sunlight.

Facts: Experts say that diethyl phthalate (DEP), which is widely used in perfumery, is not at risk and the development of human reproductive function. In experiments with rats malicious component acts dibutyl phthalate, and in the case of people who have studied mainly intermediate products dibutyl phthalate metabolism. It was carried out serious and scrupulous tests, which resulted in the diethyl phthalate was found completely harmless components. Most components of musk fragrances have also been found to be safe for human health. However, manufacturers of perfumes on the advice and insistence of experts to limit the content of their products musk notes.

Nail polishes

Assumptions: Based on the results of studies in Europe have decided to ban the use of dibutyl phthalate, which is widely used in nail polishes to provide flexibility and durability of the lacquer coating. Despite the fact that the absence of compelling evidence that dibutyl phthalate is really harmful to the human body, of the precautionary principle in Europe, decided to go on an extreme measure. Formaldehyde and toluene, which are part of the nail polish, most countries are not perceived as truly dangerous substances, to date, they are included in the list of substances approved by the relevant authorities to oversee the quality and technical standards of cosmetic products. However, the high concentration of these substances, such as factories, where people are in contact with them every day, increases the risk of cancer and disorders of the respiratory system.

Facts: prolonged debate on the safety of these substances has forced many cosmetic companies to remove dibutyl phthalate (DBP), toluene and formaldehyde formulations of nail polish. Experts believe that using a varnish containing the above components significantly increases the risk of contact dermatitis. Toluene and formaldehyde in raw form can cause skin irritation, so try to avoid contact has not yet dried nail polish skin. These components, in the quantities in which they are found in nail polishes, do not pose a threat to human respiratory function and can not be considered as factors causing cancer.

In the case of dibutyl phthalate experts estimate that even if you do every day will use five vials of lacquer, each particle of this substance will get into your body, even with this seemingly enormous concentration, you are unlikely to reach that dose, that caused disturbances in experimental rodents. The surface of the nail is quite dense, dermatologists believe that this density is sufficient to prevent harmful substances penetrate the tissue, skin or blood.

In the world every day spend a lot of research and experimentation, they are mainly carried out on animals, so to argue the extent to which a given element will affect the person is extremely difficult. For example, when studying the effects of phthalates on the quality of sperm, sperm samples were taken only from infertile men, the impact of these substances on the reproductive function of healthy men study and analysis is subjected. Scientists pushing hypotheses and assumptions understand that this is just a theory, requiring truly compelling and unambiguous evidence. Science does not stand still, so we hope that in the future we will not have to worry about the dangers that lurk in all our usual cosmetics.
