Effect of storage conditions on the stability and quality of cosmetic grade mineral oil
Release Time : 2024-12-10
Cosmetic grade mineral oil is widely used in the cosmetics industry, and its storage conditions have a crucial impact on stability and quality.
First, temperature is one of the key factors. Excessively high temperatures will accelerate the movement of cosmetic grade mineral oil molecules, making them more likely to undergo oxidation reactions with oxygen in the air. This may cause the cosmetic grade mineral oil to darken in color, produce odor, or even form rancid substances, reducing its quality. For example, when exposed to high temperatures for a long time, the oxidation rate of cosmetic grade mineral oil will be significantly accelerated, and the originally clear and transparent cosmetic grade mineral oil may gradually become turbid, affecting its effectiveness and safety in cosmetics. Low-temperature environments may increase the viscosity of cosmetic grade mineral oil and worsen its fluidity. If the temperature is too low, solidification may occur, requiring additional processing steps to restore its fluidity during use, causing inconvenience to production and application.
Humidity also affects cosmetic grade mineral oil. A high-humidity environment may cause cosmetic grade mineral oil to absorb moisture, and the mixing of moisture may cause microbial growth. The growth and reproduction of microorganisms in cosmetic grade mineral oil will decompose some of its components, destroy the stability of its chemical structure, cause the cosmetic grade mineral oil to deteriorate, produce bad odor and appearance changes, and may also affect the use of cosmetic grade mineral oil. Cosmetics pose a threat to the skin health of consumers.
Lighting conditions cannot be ignored either. Especially ultraviolet irradiation will stimulate the activity of cosmetic grade mineral oil molecules and promote photochemical reactions. Photochemical reactions may change the molecular chain structure of cosmetic grade mineral oil, causing changes in its physical and chemical properties, such as reducing its lubricity and stability, affecting its effectiveness in cosmetics, such as cosmetic grade mineral oil used in some sunscreen products. oil, if improperly stored and exposed to light, may reduce the sunscreen effect of the product and cause potential irritation to the skin.
The material and tightness of the storage container are crucial. If the container material is incompatible with cosmetic grade mineral oil, a chemical reaction may occur, causing the cosmetic grade mineral oil to be contaminated or deteriorated. For example, some plastic containers may release small molecules that dissolve into cosmetic grade mineral oil. Poor sealing will allow air, moisture and impurities to enter the container more easily, accelerating the oxidation and deterioration process of cosmetic grade mineral oil.
Other chemicals in the storage environment may also have an impact on cosmetic grade mineral oil. For example, if there are highly volatile organic solvents or acid-base substances in the storage area, they may chemically react with cosmetic grade mineral oil and change its properties and quality.
Finally, the storage time of cosmetic grade mineral oil also needs to be considered. Even under ideal storage conditions, the quality of cosmetic grade mineral oil will gradually deteriorate over time. Therefore, the first-in-first-out principle should be followed and the storage period should be reasonably controlled to ensure the stability and quality of cosmetic grade mineral oil during use.
