Can excipients alter the colour or smell of a cosmetic product?

Can excipients interact with each other?
Yes, certain excipients can interact with each other, thereby affecting the stability or effectiveness of the product.
Can we be sensitive to excipients without being sensitive to active ingredients?
Yes, it is possible to react to an excipient while perfectly tolerating the active ingredients of a product.
