Natural rubber latex contains antigenic proteins that may cause allergic reactions in people who are sensitive to latex. Allergic reactions to latex can appear as skin irritations or rashes, respiratory problems, and even anaphylactic shock (a severe allergic reaction in which blood pressure drops suddenly and the airways narrow, making breathing difficult).

Fragrance allergens: Following extensive research, the European Commission has listed 26 fragrance ingredients as allergens. Among these, the most frequently reported fragrance allergens are Amyl cinnamal, Amylcinnamyl alcohol, Benzyl alcohol, Benzyl salicylate, Cinnamyl alcohol, Cinnamaldehyde, Citral, Coumarin, Eugenol, Geraniol, Hydroxycitronellal, Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC) (also known as Lyral), Isoeugenol.

Tips to prevent allergic reactions from use of cosmetics

To prevent allergic reactions, first you need to know what you are sensitive to or allergic to. Always reading the product ingredient panel and avoiding ingredients you know or think you are allergic to. Always check the ingredient list before you buy any cosmetic products to find possible allergens. You may find terms like hypoallergenic, fragrance-free or for sensitive skin on some products, but that doesn't mean allergen-free. It is always better to check the specific ingredients present in the product, if identified.

Also, you should read the label on products and follow instructions as directed by the manufacturer before applying. It is a good idea to test a small amount of product first to ensure that you're not allergic or sensitive to the ingredients in the product.
