Function and Safety of Stabilizing Ingredients
Question
What are the functions of Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate and Benzotriazolyl Dodecyl p-Cresol in cosmetic formulations? Do these ingredients provide any benefits to the skin? Are they safe for the skin, and can they cause allergic reactions?
Answer
Based on the information available, ingredients like Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (often found in products like Protec OX) and Benzotriazolyl Dodecyl p-Cresol (often found in products like Protec UV) are primarily used as stabilizers in cosmetic formulations.
Their main function is to protect the formula itself, for example, by acting as antioxidants or UV absorbers to prevent degradation of other ingredients. They do not typically provide direct benefits to the skin.
Regarding safety, when used within recommended concentrations, these ingredients are generally considered safe for the skin based on safety assessments. However, as with any cosmetic ingredient, individual allergic reactions are possible, which are specific to each person and not necessarily related to general irritation or toxicity.
