Uvinul A Plus CAS 302776-68-7

1. Sunscreen products
The mechanism of action of chemical sunscreen agents
Diethylaminobenzoic acid hexyl ester is an efficient chemical sunscren agent, which works by absorbing the UVA band energy (320-400nm) in ultraviolet light and converting it into harmless heat energy to reduce the damage of ultraviolet light to the skin. In the UVA band, it has the highest absorption rate for ultraviolet light with a wavelength of 354 nanometers, and can provide high absorption effect for UVA1 (340-400nm band). UVA can penetrate the dermis layer of the skin,causing problems such as skin aging, wrinkles, and pigmentation, while the application of DHHB can effectively resist the invasion of UVA and protect skin health.

(1) Synergistic effect with other sunscreen agents
It is often used in combination with UVB sunscren to increase the SPF value of the product, which helps with UVB protection. For example, in sunscren formulations, combining DHHB with physical sunscrens such as zinc oxide and titanium dioxide, or other chemical sunscrens such as ethylhexyl triazine ketone, can achieve more comprehensive UV protection. Physical sunscren works by reflecting and scattering ultraviolet rays, while DHHB absorbs ultraviolet rays. The combination of the two can cover a wider range of ultraviolet wavelengths, providing more reliable protection for the skin.

(2) Product type and usage scenario

DHHB is widely used in various sunscren products, such as sunscreen, sunscren lotion, sunscren spray, etc. For daily commuters, sunscreen products containing DHHB can provide basic UV protection and reduce skin damage caused by daily UV exposure. For outdoor activity enthusiasts, such as hiking, swimming, seaside vacations, etc., high magnification sunscren products containing DHHB can better resist strong ultraviolet radiation and protect the skin from sunburn and tanning.

(3) Concentration and safety of use
In cosmetics, the maximum usage of DHHB is generally 10%. When the concentration is below 5%, it does not cause significant irritation to the skin of most people, but it is recommended for sensitive skin to undergo a behind the ear test first. It has excellent compatibility and photostability compared to other sunscrens and beauty ingredients, with good photostability. It is not as easily decomposed as avobenzone and can maintain its sunscren efficacy for a long time.

2. Baby sun exposure skincare products
Characteristics of Infant Skin and Sunscreen Needs
Baby's skin is very delicate, with a thin stratum corneum and weak resistance to ultraviolet radiation. Long term exposure to sunlight can easily damage a baby's skin, causing problems such as sunburn, redness, swelling, and blistering, and may even increase the risk of developing skin cancer in the future. Therefore, providing specialized sun care products for infants is very important.

The application advantages of Uvinul A Plus in infant products:
DHHB has good safety and photostability, making it suitable for addition to infant sun care products. Its gentle formula can reduce irritation to the baby's skin while effectively absorbing ultraviolet radiation, providing reliable protection for the baby's skin. For example, some baby sunscrens, lotions, and other products contain DHHB, which can protect the baby's skin from UV damage when they go out.

(1) Architectural Coatings
The photo aging problem and protection requirements of architectural coatings
Architectural coatings are exposed to outdoor environments for a long time and are susceptible to factors such as ultraviolet radiation, wind and rain, temperature changes, etc., which can cause light aging phenomena such as fading, powdering, and cracking, affecting the appearance and service life of buildings. In order to improve the weather resistance and decorative properties of building coatings, it is necessary to add additives with ultraviolet absorption function.

(2) Application effect of DHHB in architectural coatings
Adding DHHB to architectural coatings can effectively absorb UVA band energy in ultraviolet radiation, reducing the damage of ultraviolet radiation to pigments and resins in coatings. It can maintain the color brightness and glossiness of the coating, extending the service life of the coating. For example, adding DHHB to exterior wall coatings can maintain a good appearance of buildings during long-term use, reducing maintenance and repainting costs.

(3) Application cases of different types of architectural coatings
DHHB is suitable for various types of architectural coatings, such as latex paint, real stone paint, textured paint, etc. Adding DHHB to latex paint can improve its weather resistance and color retention, making the wall color long-lasting and bright. Adding DHHB to real stone paint and textured coatings can enhance the durability of the coatings and prevent cracking and peeling caused by ultraviolet radiation.

(1) Performance requirements for automotive coatings and the importance of UV protection
Automotive coatings need to have good appearance, glossiness, weather resistance, and corrosion resistance. Ultraviolet radiation is one of the main factors causing the aging of automotive coatings. Long term exposure to sunlight can easily lead to problems such as fading, loss of gloss, and peeling of the car paint surface, affecting the beauty and value of the car. Therefore, improving the UV protection capability of automotive coatings is crucial.

(2) The role and application of DHHB in automotive coatings

DHHB can be added as a UV absorber to automotive coatings, absorbing UV energy and protecting pigments and resins in the coatings. It can be evenly mixed with other coating components to form a coating with UV protection function. DHHB can be added to both the original car paint and car repair paint to improve the weather resistance and gloss retention of the coating, keeping the car paint surface bright and new for a long time.

(3) The impact and development trend on the automotive coatings industry
With the continuous improvement of consumers' requirements for the appearance quality of cars, the demand for ultraviolet absorbers in the automotive coatings industry is also increasing. The application of DHHB can improve the performance and quality of automotive coatings, meeting the market's demand for high-quality automotive coatings. In the future, with the development of the automotive industry and the increasing demand for environmental protection, the research and development of more efficient and environmentally friendly automotive coatings containing DHHB will become the industry's development trend.

1. Optical filter
(1) The role and application fields of optical filters
Optical filter is an optical component that can selectively transmit or reflect light of specific wavelengths, widely used in fields such as photography, videography, display technology, laser technology, etc. In photography and videography, filters can adjust the color, intensity, and contrast of light, improving the shooting effect; In display technology, filters can improve the color saturation and contrast of displays; In laser technology, filters can be used to select lasers of specific wavelengths.

(2) The application principle and advantages of DHHB in optical filters
DHHB has the characteristic of absorbing ultraviolet rays in the UVA band, which can be applied to optical filters and made into ultraviolet filters.
