Antioxidants
BHT, also known as butylated hydroxytoluene, is a synthetic antioxidant widely used in the cosmetics industry. Its chemical structure is benzene-based, and it acts as a protective agent against fat oxidation, helping to maintain the freshness and effectiveness of products for longer. BHT is often found in lotions, creams, and other skin care products because it not only protects formulas from aging, but can also help prevent skin damage from free radicals. Although it is a synthetic ingredient, its benefits for the skin and product longevity are well known. Thus, BHT is a valuable component that ensures our favorite cosmetic products remain effective and safe to use.
Purpose and Benefits
BHT also has the ability to stabilize cosmetic formulas, keeping their composition unchanged even under challenging environmental conditions. This is especially important in products that are regularly exposed to oxygen or light, as these factors can promote the breakdown of ingredients. This property makes BHT an indispensable component in both skin care and hair care products, where stability directly affects product effectiveness. One of the subtle but significant advantages of this ingredient is its ability to protect active ingredients from degradation. Some vitamins or plant extracts used in cosmetics are sensitive to oxidation, so they can quickly lose their beneficial properties. BHT acts as a shield, helping to maintain the strength and performance of these ingredients, so that the skin or hair can benefit from the product’s maximum potential. An equally important aspect is that the use of BHT reduces the need for preservatives in formulas. Preservatives are often necessary to ensure that products are safe for longer periods, but their excess can pose a risk of sensitivity. BHT, as an antioxidant, not only extends the shelf life of the product, but also allows maintaining a balanced composition without causing additional stress to the skin or hair.
Security Information
This ingredient, although widely used in cosmetics, raises some discussion regarding its safety. Studies show that BHT can cause skin irritation or allergic reactions in some individuals, especially those prone to sensitivity to chemicals. For this reason, it is advisable to perform a patch test before using products containing BHT. The European Union and the US Food and Drug Administration (FDA) recognize BHT as safe for use, but recommend adhering to certain doses and not using it in large quantities to avoid potential adverse reactions. As with any other cosmetic ingredient, consumers are advised to carefully monitor their skin’s reactions and consult a specialist if they have any doubts.
Sustainability and Extraction
The production and use of this ingredient raise various environmental and ethical concerns. While BHT is often obtained synthetically, the chemicals required for its production can have a negative impact on ecosystems. Synthetic processes often require high energy consumption, which contributes to greenhouse gas emissions. Furthermore, the raw materials used are often derived from petroleum products, which raises concerns about resource depletion and pollution. From a social perspective, BHT production can affect local communities where industrial activities take place, raising occupational safety and health issues. Therefore, while BHT can be an effective ingredient, the aspects of its production and use encourage the search for more sustainable and ethical alternatives.
Products
Lotions, creams, and serums are the most common products where BHT can be found. This ingredient is extremely popular in skincare products, such as Innisfree moisturizers or Etude House eye serums. It can also be found in hair care products, such as shampoos and conditioners, where it helps protect the ingredients from oxidation. In addition, BHT is often found in decorative cosmetics, including lipsticks and foundations, giving them longevity. Missha and The Face Shop brands also use this ingredient in their popular products to ensure that their formulas remain stable and effective for a long time.
