The photoinitiator EHA (isooctyl p-dimethylaminobenzoate, trade name ESCALOL507) is a good UV absorber in the UVB region, and its maximum UV absorption peak is 311nm (ethanol solution). As an anti-ultraviolet active ingredient, it is widely used in sunscreen cosmetics abroad, and the dosage is very large. The US FDA lists sunscreens containing this product ingredient as the first cosmetic recommended by Chemicalbook. At present, with the continuous and rapid development of my country's sunscreen product market year by year, it is necessary to import isooctyl p-dimethylaminobenzoate (photoinitiator EHA) raw materials from abroad every year as an anti-aging agent for industrial products. Therefore, it is of great practical significance to carry out research on the synthesis process of isooctyl p-dimethylaminobenzoate (photoinitiator EHA), and it is also helpful to realize the localization of the product.

3-O-ethyl ascorbic acid is a new generation of Vitamin C derivative that provides superb whitening effects, also serves as a potent anti-aging active that boosts collagen synthesis and protects skin from DNA damage. It exhibits strong inhibition effect on melanogenesis, reduces dark spots and age spots, fights photoaging by interfering with inflammatory cytokines, such as IL-6, and reverse ROS production to achieve free radical scavenging purpose. 3-O-ethyl ascorbic acid is effectively a newer form of Vitamin C that offers a better overall performance. It is water soluble with excellent heat and photostability profile. Best of all, it is highly stable and easy to formulate.

Ribose is a sugar molecule that occurs naturally in the body and is made from blood glucose. It is a key component of adenosine triphosphate (ATP)-a molecule involved in storing and releasing energy, muscle contraction, and nerve impulse propagation-and ribonucleic acid (RNA), a molecule involved in protein synthesis and other cell activities. Also known as D-ribose, it is sold as sports nutrition powder supplement to reduce fatigue and improve athletic performance. The synthetic form of this supplement is called N-ribose. For d ribose powder bulk from Gihi Chemicals. Ribose shows some promise as a treatment for people with energy deficits, such as chronic fatigue syndrome and fibromyalgia, and is popular among athletes looking to increase energy, boost stamina, and enhance athletic performance.

Fucoidans belong to a class of complex sugar molecules known as a polysaccharides. All fucoidans share the same backbone structure, but vary greatly in their molecular composition, and different types show different kinds of biological activities. Fucoidans are found primarily in brown seaweed, but both the level and composition of the fucoidan depends on the exact species of seaweed and the harvest conditions. Preclinical studies in animal models suggest some fucoidans may protect against inflammation and oxidative stress. Fucoidan consumption is generally regarded as safe.
