Does the short shelf life of an oil affect the product's shelf life?
คำถาม
Does the naturally short shelf life of an ingredient like Grape Seed Oil, which tends to go rancid and develop an unpleasant odor as it ages, impact the overall practical shelf life and usability of the finished cosmetic product, even if other ingredients remain stable and effective?
คำตอบ
Subject: Does the short shelf life of an oil affect the product's shelf life?
Based on the information provided:
Generally, if one ingredient in a formulation degrades but other ingredients remain effective, the entire product is not necessarily considered expired, and the formula may still retain some efficacy.
However, in the case of natural oils like Grape Seed Oil, as they age, they tend to become rancid and develop an unpleasant odor. While other components of the product might still be active, this rancidity can make the overall product feel unsuitable or undesirable for use.
Therefore, while the oil's short shelf life might not technically expire every component in the formula, its degradation (rancidity and odor) can significantly impact the perceived quality and usability of the final product, effectively limiting its practical shelf life.
