Credibility and Properties of RonaCare® AP as an Antioxidant (vs. Vitamin E)

Dear C7, Thank you for sharing the information you remember about RonaCare® AP (Bis-Ethylhexyl Hydroxydimethoxy Benzylmalonate) and your question about the credibility of the research from Merck. Based on the information you provided and the expert comments, here is a summary and answer to your question: 1. Credibility of Merck: Merck is a reputable company in the chemical and pharmaceutical industry. Research from the manufacturer often highlights the key properties of their products. However, research conducted by the manufacturer itself may aim to showcase the potential of the substance in aspects the company wants to present. This does not mean the information is incorrect, but independent research from other sources would further enhance credibility. 2. Mentioned Properties: * Antioxidant Properties: It is plausible that RonaCare® AP has comparable efficacy to natural Vitamin E and high stability. However, the effectiveness of antioxidants is often application-specific. Merck's research may show good results under their test conditions, but real-world application in cosmetic products on the skin requires considering additional factors like skin absorption and safety, where Vitamin E is widely accepted due to its long history of use. * Stability and Efficacy under UV Light: The substance having high stability and potentially increased efficacy under UV light is interesting. However, sufficient testing data is needed to confirm the claimed 24-hour efficacy under real-use conditions. * Sun Protection and Protection from UVA Damage: Antioxidants can indeed help protect the skin from UV damage, including UVA. Vitamin E also has this property. However, the best method for sun protection is using UV blockers to prevent UV rays from hitting the skin directly, which is more effective than using antioxidants to repair damage after sun exposure. * Stabilizing Avobenzone and OMC: It is possible that RonaCare® AP helps stabilize sunscreens like Avobenzone and OMC. Since Avobenzone is easily degraded by light, using antioxidants or stabilizers is common in sunscreen formulas containing Avobenzone. However, the primary way to stabilize Avobenzone is to prevent UVB rays from degrading it in the first place, which is more important than using an antioxidant after light exposure. Other substances like CoQ10 have also been tested and shown to extend the life of Avobenzone better than Vitamin E. 3. Conclusion on Credibility: The information you remember from Merck's research is theoretically plausible and consistent with the properties some antioxidants possess. However, as it is research from the manufacturer and there are limited publications about this specific substance as mentioned by you and the expert, further studies and testing in various applications, including independent research, are needed to confirm its overall effectiveness and suitability for widespread use in cosmetic products. In summary, information from Merck is credible as a manufacturer, but the claimed properties require further confirmation from testing in diverse applications and independent research to provide a clear picture of its effectiveness and suitability for use. Based on our search in the system, we found information about some of the substances you mentioned, which might be useful: * Avobenzone (Product ID 267) * Octyl Methoxycinnamate (OMC) (Product ID 523) * Vitamin E (Tocopheryl Acetate) (Product ID 65) * Coenzyme Q10 (CoQ10) (Product ID 483) For RonaCare® AP or Bis-Ethylhexyl Hydroxydimethoxy Benzylmalonate, a preliminary search in our system did not find direct product information at this time. I hope this information is helpful. If you have any further questions, feel free to ask.
