Benzophenone 4
Benzophenone is an organic compound with the chemical formula (C₆H₅)₂CO. It is a pale yellow solid that belongs to the class of aromatic ketones. Benzophenone is widely used as a building block in the synthesis of various organic compounds and also finds applications as a photoinitiator, UV absorber, and fragrance ingredient in the manufacturing of cosmetics, plastics, adhesives, and coatings. It exhibits ultraviolet (UV) light-absorbing properties, making it useful in sunscreens and other products designed to protect against harmful UV radiation.
Bernoulli Tube Apparatus
The Bernoulli tube apparatus, also known as a Venturi tube apparatus, is a scientific device used to demonstrate the principles of fluid dynamics, particularly the Bernoulli's principle. It consists of a specially shaped tube with a constricted region, often referred to as a Venturi section. When fluid (liquid or gas) flows through the tube, the constricted section leads to changes in pressure and velocity according to Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases and vice versa. This apparatus is commonly used in educational settings to visually illustrate how the flow of a fluid can affect its pressure, helping to explain various phenomena like lift in aircraft wings, fluid flow through pipes, and more.
Beta Arbutin
Beta arbutin, also known as β-arbutin, is a naturally occurring compound derived from plants, primarily bearberry plants. It is a glycosylated form of hydroquinone and is widely used in the skincare and cosmetic industry for its skin brightening and lightening properties.
Beta arbutin works by inhibiting the enzyme tyrosinase, which is involved in the production of melanin, the pigment responsible for skin color. By reducing the activity of tyrosinase, beta arbutin helps to diminish the formation of melanin, thereby reducing the appearance of dark spots, hyperpigmentation, and uneven skin tone.
What sets beta arbutin apart from regular arbutin is that it has a higher stability and is considered to be a safer alternative due to its reduced potential to convert into hydroquinone. Hydroquinone, although effective in lightening the skin, has been associated with potential side effects such as skin irritation and long-term skin damage.
Overall, beta arbutin is widely valued in the skincare industry for its skin brightening and lightening effects, making it a popular ingredient in various skincare products targeting hyperpigmentation and uneven skin tone.
