introduction	octyl p-methoxycinnamate is a commonly used sunscreen, antioxidant and ultraviolet absorber. According to relevant studies, there are mutagenic effects, teratogenic effects and developmental toxicity on human body, and it has potential chronic health effects.
use	is used to prepare sunscreen (cream, milk, liquid) and other skin care cosmetics, which can effectively absorb ultraviolet rays in sunlight, prevent skin redness, sunburn and ink, and is also a therapeutic drug for photodermatitis. It can be used as an anti-aging agent and ultraviolet absorber for plastics and inks in industry. oil-soluble liquid UV-B absorbent, which can be compounded with various sunscreen agents mainly used for ultraviolet absorption in cosmetics
production method	p-toluenesulfonic acid is added to the mixture of octanol and anisaldehyde, malonic acid and pyridine, after esterification reaction, neutralization, dehydration, constant boiling distillation and refining to obtain the product.
