Question
I have questions regarding cosmetic ingredients:
1. Could you please provide information on the safety and properties of Caprylhydroxamic Acid and explain why it is not available for sale compared to Mild Preserved Eco?
2. What is the difference between Ethyl Alcohol 99.9% and 95%, and which is more suitable for cosmetic formulations, particularly concerning odor, especially when used at high concentrations?
3. (Referring to the staff's correction) The staff mentioned the INCI names `Propanediol`, `Ethylhexylglycerin`, and `Caprylyl Glycol`. Could you clarify the context or function of this ingredient blend?
Answer
Based on the forum discussion:
- Caprylhydroxamic Acid: The staff confirmed that Caprylhydroxamic Acid is highly safe. However, the company does not plan to sell it as its properties are not significantly different from Mild Preserved Eco.
- Ethyl Alcohol 99.9%: The choice between 99.9% and 95% Ethyl Alcohol depends on the application. Higher purity alcohol (99.9%) is recommended for cosmetic formulations, especially when used at higher concentrations, because it has a much milder odor compared to 95% alcohol. Using 95% alcohol in formulas with high percentages can lead to significant odor problems.
