What is BHT and why is it used in hair products?

When it comes to beauty products, we often find ourselves using items that we don't fully understand. One such ingredient that is commonly found in hair products is BHT. But what is BHT, and why is it used in hair products?

Defining BHT.

BHT stands for Butylated hydroxytoluene, a synthetic antioxidant that is used to preserve the shelf life of beauty products. It is a white, crystalline powder that is odorless and tasteless.

BHT is commonly found in hair products such as shampoos, conditioners, and hair sprays to extend their shelf life.

Functions of BHT in Hair Products.

There are several functions of BHT in hair products. Its primary function is to prevent the oil in hair products from going rancid. When hair products are opened, they can come into contact with air and light, which can cause the oils in the products to break down, leading to a rancid smell, and a change in texture.

In addition to preserving the shelf life of hair products, BHT also helps maintain their color, texture, and fragrance. It also promotes a uniform distribution of the ingredients in the product, ensuring that it is consistent throughout.

Although BHT is primarily used for its preservation properties, it also has some skincare benefits. When used in hair products, it can help protect the scalp from damage caused by UV light.

Safety of BHT.

There is a lot of debate over the safety of BHT, especially when used in high concentrations. Studies have shown that BHT can lead to DNA damage, liver damage, and cancer. These studies were conducted on rats and mice, and it is unclear whether the same effects would be seen in humans.

Furthermore, the European Union has classified BHT as a skin irritant and banned it in cosmetics that are left on the skin for an extended period. In the United States, the Food and Drug Administration (FDA) has deemed BHT to be safe for use in amounts up to 0.2% of the weight of the finished product.

However, some beauty brands have chosen to use alternatives to BHT in their hair products to cater to customers who may be concerned about the safety of BHT.

Conclusion.

In conclusion, BHT is a synthetic antioxidant that is commonly used in hair products to preserve their shelf life. Its primary function is to prevent the oil in hair products from going rancid, but it also has some skincare benefits.

Although there is some controversy surrounding the safety of BHT, it is generally considered to be safe in low concentrations. However, it is up to each individual to determine whether they want to use products that contain BHT or not.

If you have any concerns about the safety of BHT or any other ingredients in hair products, you can always contact the manufacturer or reach out to a dermatologist for advice.
