If you are studying whether the same type of salt is safe, then you have come to the right place. In this article, we will answer: What is homosalate? Is homsalate safe for humans? Is homosalate Reef Safe?

Physical sunscreen typically uses one or two active ingredients.


Chemical sunscreen requires the use of 3-4 or more active chemical ingredients to a) cover the entire UV spectrum and/or b) compensate for the deterioration of the ingredients.


If you are studying whether the same type of salt is safe, then you have come to the right place. In this article, we will answer:

What is homosalate?
Is homsalate safe for humans?
Is homosalate Reef Safe?

Let's get started.

What is Homeosalate?


Homosalate is an oil soluble chemical sunscreen ingredient used to absorb UVB rays (which can cause sunburn in the upper layer of the skin). Ironically, it is a weak UV filter (with an SPF value of 4 at a concentration of 10%) and is not light resistant (which means it decomposes in sunlight). It is a derivative of salicylic acid. Salicylic acid is used to remove the outer layer of the skin and treat warts and acne.


Since the same hydrochloride only covers the UVB spectrum, it is usually used in combination with avobenzone (a chemical UVA filter) to obtain broad-spectrum coverage.


Due to the fact that most of the ingredients in chemical sunscreens work by being absorbed by the skin, they do not adhere to the skin like zinc oxide.


On the label, isomorphic salicylates may also be listed as isomorphic salicylic acid, or HMS.

Is homsalate safe for humans?


Research has shown that it is a weak hormone disruptor, and sunlight can degrade this chemical into potential harmful byproducts.


This study also links homologous salts with hormonal disorders, which may also promote the absorption of pesticides (if you use sunscreen and pesticide products, or use pesticides in gardening). Once through the skin, these chemicals usually enter your bloodstream.


Some laboratory studies (in vitro) have shown that homologous salts may also have some estrogenic activity.


In 2019, a study published by FDA showed that oxybenzone, octanoate, octanoate, oxonene, homosalate and avobenzone would be absorbed by the human body after one use. The US Food and Drug Administration also found that after a few weeks of use, the ingredients of sunscreen can be detected in the skin and blood.


All waxy sunscreen and skincare products do not contain high salt levels.


The study found that the growth and reproduction of human breast cancer cells exposed to high salt is 3.5 times higher than that under normal conditions. The estrogenic activity of this chemical has also been observed in human placental tissue, which has raised concerns that pregnant women may be exposed to this chemical.


Although there is extensive research on the toxicity and effects of homosalate on the human body, homosalate is recognized worldwide. The maximum usage approved by the US Food and Drug Administration can reach 15%.


We recommend that children, adults, and pregnant women avoid using this chemical in sunscreen and any skincare products.

Is homosalate Reef Safe?


The same salt has always existed in the environment and is not easily decomposed. UV filters, such as high salinity, can enter coastal waters directly through swimmers' bodies and/or indirectly from sewage treatment plants. Many of these chemicals have been found in marine organisms, including fish and corals, as well as in seabed sediments.


The impact of oxybenzophenone on coral has been widely studied, but unfortunately, there is not enough data to determine the safety of the same hydrochloride on coral reefs. However, simply because there is not a large amount of scientific evidence to suggest that salts are harmful to coral reef environments does not mean that they can be safely used. Further research is needed to better understand which components are safe and pose a threat to marine ecosystems. At the same time, we recommend avoiding the use of homosalate salts.


The term 'coral reef safety' is not regulated by the US Food and Drug Administration, and its use is increasing, largely due to the sunscreen industry's desire to attract ecologically conscious consumers.
