Question
What is the suitable pH range for cosmetic products when using aluminum packaging? Why is it important to stay within this range?
Answer
Subject: Aluminum Packaging Compatibility
Based on the information provided, the suitability of aluminum packaging for cosmetic products is primarily determined by the product's pH.
- Products with pH outside the 4-9 range are generally not suitable for aluminum packaging.
- This includes highly acidic products (pH below 4) and highly alkaline products (pH above 9).
- Such extreme pH levels can react with the aluminum, potentially leading to corrosion of the packaging and affecting the stability or quality of the cosmetic product itself.
While I cannot use the available tools to provide a specific list of cosmetic types or ingredients that fall outside this pH range, examples of products that might have pH levels unsuitable for aluminum include strong chemical peels (acidic) or certain hair treatments (alkaline).
It is always recommended to test the compatibility of the specific product formulation with the packaging material.
