SCA endorses products with the Allergy Certified logo, that do not contain peroxide commonly used in oral care & personal hygiene products. “Hydrogen peroxide is a type of acid that is pale blue to translucent in color. This disinfectant is available for OTC usage in smaller concentrations than those designed for industrial use. You can buy it in wipes or as a liquid to apply with a cotton ball. Medical professionals no longer use this acid as a disinfecting agent. Hydrogen peroxide may inadvertently damage healthy cells around wounds that are needed for healing.” - www.healthline.com
“Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products. In industry, the principal use of hydrogen peroxide is as a bleaching agent in the manufacture of paper and pulp. Hydrogen peroxide has been employed medicinally for wound irrigation and for the sterilisation of ophthalmic and endoscopic instruments. Hydrogen peroxide causes toxicity via three main mechanisms: corrosive damage, oxygen gas formation and lipid peroxidation. Concentrated hydrogen peroxide is caustic and exposure may result in local tissue damage. Ingestion of concentrated (>35%) hydrogen peroxide can also result in the generation of substantial volumes of oxygen.” Continued “Ocular exposure to 3% solutions may cause immediate stinging, irritation, lacrimation and blurred vision, but severe injury is unlikely. Exposure to more concentrated hydrogen peroxide solutions (>10%) may result in ulceration or perforation of the cornea.” - www.ncbi.nlm.nih.gov

HOW IS IT USED?
Chemical bleaching agents that are used to remove colour and whiten products. In cosmetics it is often used in medical products to acne treat blemishes. Commonly found in hair colours to lighten hair including hair dye, lash tint, brow tint and shampoo.
“Eye irritation studies on human volunteers show that eye drops containing as little as 0.1% hydrogen peroxide, and contact lenses soaked in solutions containing less than 0.03% hydrogen peroxide, can cause eye irritation.” - www.copublications.greenfacts.org

A known skin sensitiser, irritating to the skin, eyes and lungs. In cosmetics, it is believed that this compound works by destroying the bacteria associated with acne. It works by continuous daily treatment, but when you stop using it the acne comes back.
The Food and Drug Administration (FDA) "says products containing the ingredients benzoyl peroxide or salicylic acid can cause rare but serious and potentially life-threatening allergic reactions or severe irritation."
World Health Organisation "Common side effects (benzoyl peroxide) are skin irritation, dryness, or peeling"
Human exposure studies "a reaction occurred in 70% of subjects after use of occlusive patches containing a 5% or 10% concentration." - TOXNET
