Salicylate Part 2 - Salicylate in Everyday Products

Salicylic Acid is sometimes labeled as beta hydroxy acid (BHA). It can be obtained from the bark of willow trees.

In 1989, Salicylic Acid was also isolated from the perennial herb Meadowsweet by German researchers.

There are some researchers who believe that salicylate is an essential micronutrient in the human diet. They call it the 'Vitamin S'.

Salicylic Acid is a monohydroxybenzoic acid. It is a type of phenolic acid and a beta hydroxy acid. Phenolic acid is a class of compounds grouped together due to their similar chemical structure. In the world of cosmetics and beauty products, salicylic acid is labelled as beta hydroxy acid.

2. C12-15 Alkyl Salicylate
3. Capryolyl Salicylic Acid
4. Hexyldecyl Salicylate
5. Isocetyl Salicylate
6. Isodecyl Salicylate
7. Ethylhexyl Salicylate
8. Methyl Salicylate
9. Myristyl Salicylate
10. Tridecyl Salicylate

Salicylic Acid, its salts and esters have many functions and these ingredients may be used in moisturizers, skin cleansing products, shampoo, skin care, hair care, suntan and sunscreen products, mouthwashes and dentifrices.

Here are some of the uses of Salicylic Acid, its salts and esters.

6. TEA-Salicylate & Ethylhexyl Salicylate
This is used as a sunscreen agent (absorbs, reflect or scatter UV rays) and an ultraviolet light absorber (protects cosmetic products from deterioration).

7. Butyloctyl Salicylate, C12-15 Alkyl Salicylate, Capryolyl Salicylic Acid, Hexyldecyl Salicylate, Isocetyl Salicylate, Isodecyl Salicylate & Tridecyl Salicylate
These are used as skin conditioning agents. They either act as lubricants on the skin surface which cause the skin to look smooth and soft. They also can help the skin stay hydrated by drawing moisture from the surrounding air. They also enhance the appearance of dry or damaged skin by reducing flaking and restoring suppleness.

Many months ago, a lady wrote to me to share with me about her daughter who is also salicylate sensitive. And she is a chemist! Here is the link to her blog. Hopefully her blog can shed more light on salicylate sensitivity!

S is for Salicylate!
