If a formulation requires incorporating small amounts of water into a hydrocarbon base, which type of base is appropriate?

• A. Absorption bases
• B. Hydrocarbon bases
• C. Water-soluble bases
• D. Gelling bases

Answer: (A)

Absorption bases are designed to take up water while still behaving like an oil-based base. When you need to incorporate small amounts of water into a hydrocarbon base, these bases form a water-in-oil emulsion, allowing water-containing ingredients to be blended without separating. Pure hydrocarbon bases won’t accommodate water, and water-soluble bases aren’t hydrocarbon, so they don’t keep the base oil phase intact. Gelling bases don’t inherently enable water uptake in the same way. So the base that best fits the requirement is an absorption base because it combines an oil-based texture with the ability to absorb and hold water.
