Understanding "Aloe Vera Leaf Juice" and 10:1 Concentration in Cosmetics
Question
When cosmetic ingredient lists mention "Aloe Vera leaf juice", does it always refer to freshly squeezed juice?
If processed forms like powder or concentrated extracts such as `Aloe Vera Extract (extraction ratio 10:1 FullAssay™)` are used, why are they still referred to as "Juice", and what does the 10:1 ratio signify in this context?
Answer
Understanding "Aloe Vera Leaf Juice" in Cosmetics
When cosmetic ingredient lists mention "Aloe Vera leaf juice," it often refers to Aloe Vera that has been processed to remove water, rather than freshly squeezed liquid directly from the leaf.
This processing typically involves methods like freeze-drying or spray-drying the fresh Aloe Vera juice. These methods result in a concentrated powder or solid form. When this dried material is rehydrated by adding water back, it effectively becomes Aloe Vera juice again.
Products such as the Aloe Vera Extract (extraction ratio 10:1 FullAssay™) are examples of such processed forms. They are concentrated extracts that, when used in formulations, contribute the beneficial properties of Aloe Vera juice.
Using processed and rehydrated forms offers advantages in terms of stability, preservation of active compounds, and ease of formulation compared to using raw, fresh juice directly from the plant.
Therefore, while not the raw liquid, the term "Juice" accurately reflects the composition of the ingredient after rehydration, providing the same beneficial properties derived from the Aloe Vera leaf.
