1, 2 – Hexanediol synthesised through the catalytic reaction 1-hexene in the presence of hydrogen peroxide as an oxidizing agent.
1, 2 – Hexanediol is generally considered as safe when used in low concentration in the cosmetic products as it can cause irritation to eyes when used in higher concentration.
1, 2 – Hexanediol is a synthetic chemical which is synthesised through industrial processes. It is also used as a synthetic alternative to paraben which is used in cosmetic products.Â
1,2-Hexanediol is good for the skin and is widely used in cosmetic and personal care products as a preservative, moisturising agent, and as an emollient, helping to inhibit the growth of microorganisms, extending the shelf-life of the product, and retaining the moisture of the skin.
