Xi'an Sonwu Biotech Co., Ltd. is one of the most professional manufacturers and suppliers of avobenzone powder in China. We warmly welcome yuo to wholesale bulk avobenzone powder for sale here from our factory. Quality products and reasonable price are available.
What Is Pure Avobenzone
Avobenzone powder is a benzophenone UV absorber and an essential organic synthesis intermediate, which can block UVA in the whole band (320-400nm). It is an efficient broad-spectrum oil-soluble UVA filter. Combined with other UVB sunscreens, it can provide full UVA and UVB protection to prevent photo-induced skin diseases. There are many kinds of ultraviolet absorbers, among which benzophenone ultraviolet absorbers are widely used, and this kind of absorber has great practical research value. Avobenzone is one of the few organic sunscreens that can absorb UVA1, and UVA1 has the largest span of ultraviolet rays. It is also the band region that most ultraviolet absorbers cannot prevent: 340-400 nanometers. It can provide substantial protection in the UVA1 range, combined with other UVB absorbers, and the whole formula can provide broad-spectrum UVA/UVB protection. Xi'an Sonwnu provides bulk Avobenzone, and if you want to buy them, you can contact Xi'an Sonwnu without hesitation.

What Are Ultraviolet Rays
According to different biological effects, ultraviolet rays are divided into four bands according to wavelength:
The classification of ultraviolet rays includes UVA, UVB, UVC, and UVD. Among them, UVC has been absorbed and scattered by the ozone layer in the atmosphere because of its short wavelength, so it cannot reach the ground. The wavelength of UVB ranks among the three. The wavelength can only get to the skin's epidermis, while UVA with a longer wavelength will penetrate deep into the skin, damage the dermis layer of the skin, and cause skin aging.
1. UVA band, wavelength 320-400nm, also known as long-wave dark spot effect ultraviolet rays. It can penetrate the most transparent glass and plastic. In addition, UVA can directly reach the skin's dermis, destroy elastic fibers and collagen fibers, and make our skin tan. The 360nm wavelength UVA ultraviolet light conforms to the phototaxis response curve of insects and can be used to make insect trap lamps. The 300-400nm wavelength UVA ultraviolet rays can pass through the unique colored glass lamp tube that completely cuts off visible light and only radiate near-ultraviolet light centered at 365nm, which can be used in ore identification, stage decoration, currency inspection, and other places.
2. UVB band, wavelength 275 ~ 320nm, also known as medium-wave erythema effect ultraviolet light. Medium penetrating power, its shorter wavelength part will be absorbed by transparent glass, the ozone layer will absorb most of the medium-wave ultraviolet rays contained in sunlight, and less than 2% can reach the earth's surface, especially in summer and afternoon. UVB ultraviolet rays have an erythema effect on the human body. They can promote mineral metabolism in the body and the formation of vitamin D, but long-term or excessive exposure will cause the skin to tan and cause redness, swelling, and peeling. Ultraviolet health care lamps and plant growth lamps are made of special transparent purple glass (which does not pass through light below 254nm) and phosphors with a peak near 300nm.
3. UVC band, wavelength 200 ~ 275nm, also known as short-wave sterilization ultraviolet light. It has the weakest penetrating ability and cannot penetrate most transparent glass and plastics. The ozone layer almost entirely absorbs the short-wave ultraviolet rays contained in sunlight. Short-wave ultraviolet rays are very harmful to the human body. Short-term exposure can burn the skin, and long-term or high-intensity exposure can also cause skin cancer. The ultraviolet germicidal lamp emits UVC short-wave ultraviolet rays.
4. UVD band, wavelength 100 ~ 200nm, also known as vacuum ultraviolet.
What Is UVA
The UVA band is part of the division of ultraviolet wavelengths, with a wavelength of 320-420nm, also known as long-wave dark spot effect ultraviolet rays. It is a terrible sun killer. With its relatively long wavelength and strong penetrating ability, it can penetrate the surface layer of the skin and penetrate deep into the tissues below the dermis. It can destroy collagen, elastic fiber tissue, and other delicate structures inside the skin, resulting in wrinkles and Fine lines that make the skin sag and age. This is called photoaging in medicine.
In the energy distribution of ultraviolet rays in sunlight, UVA is 15 times that of UVB, which is the leading cause of skin tanning. It can reduce the hyaluronic acid content bound to water in the skin, dry the skin, accelerate the formation of melanin, and darken the complexion. It is also a significant cause of skin diseases.
The European and American systems use PPD to refer to the multiples of prolonging the skin's tanning time by UVA to represent long-term tanning. After 2 hours of UVA exposure, the skin continues to be tanned. The protection factor is most in line with the actual prevention of dark spots. PPD can best reflect the long-term tanning effect of sunscreen products on UVA. The Japanese system uses PA to reflect the impact of UVA tanning, and the number of plus signs expresses it:
PA+ = PPD 2-4
PA++ = PPD 4-8
PA+++ = PPD>8
What Is The Molecular Formula Of Avobenzone
At present, the methods for synthesizing avobenzone mainly contain the following:
①Condensation-addition elimination of hydration method, that is, p-methoxyacetophenone and p-tert-butylbenzaldehyde undergo condensation, bromine addition, elimination of alkyne, and hydration to obtain the product with a yield of 58%. This method has a long route and low cost. High, low output;
②Claisen ester condensation method, that is, the reaction of p-methoxy Chemicalbook acetophenone and methyl p-test-butyl benzoate, the yield is 63.6%, the method is low in cost and easy to operate, but the product is low;
③ Aldehyde and ketone condensation methods, that is, p-methoxyacetophenone and p-tert-butylbenzaldehyde, are condensed into alcohol and oxidized, with an output of 34.6%. This method is easy to operate, high in cost, and low in profit.
What Is Avobenzone Used For In Skin Care
Avobenzone powder is an oil-soluble sunscreen. It is classified as a "chemical" sunscreen because it absorbs a wider wavelength of UV rays, converting them into less harmful infrared radiation (heat energy). It is marketed as a "broad-spectrum" sunscreen because it resists the full range of UVA rays. It is one of the sunscreens with a wide range of UV protection, so it is widely used in sunscreen products. It is used in cosmetics to prevent other ingredients from deteriorating in the sun.
Avobenzone provides broadband protection against UVA rays. They are safe without irritating the skin. To date, no adverse effects on skin cells have been demonstrated. They function effectively in sunscreens. Since photostability is not very high, it can be stabilized by other UV filters.
Side Effects
Avobenzone appears to be nontoxic and nonirritating to the skin. However, because it is often used with photo stabilizers, there is a risk of skin irritation and low toxicity. Some studies show that the body can absorb it, so it is not recommended for children and pregnant women. Some skin experts believe it is as harmful as PABA. Some studies have shown that this ingredient behaves like the hormone estrogen; however, the Scientific Committee on Cosmetics and Non-Food Products (SCCNFP) Products ) negates the latter claim.
Both the Food and Drug Administration (FDA, Food and Drug Administration) and the Cosmetics Directive of the European Union (the Cosmetics Directive of the European Union) consider this ingredient to be safe and have approved its safe use concentrations of 3% and 5%, respectively.
