Addressing Oiliness in Your Night Cream Formula

Regarding your night cream formula containing 70% Fractionated Coconut Oil (Caprylic/Capric Triglyceride) and 30% other non-oil ingredients, it's understandable to be concerned about the texture.

Fractionated Coconut Oil (Caprylic/Capric Triglyceride) is widely known as a lightweight, non-greasy emollient that absorbs relatively quickly and leaves a smooth, silky feel without significant stickiness. Products like Fractionated Coconut Oil and Caprylic/Capric Triglyceride (e.q. Myritol 318) are examples of this ingredient.

However, using any oil or emollient at a concentration of 70% is very high for a typical cream formulation, especially if the remaining 30% are non-oil components (like water, thickeners, etc.). While Caprylic/Capric Triglyceride is light compared to many other oils, a 70% concentration will likely result in a product that feels quite rich and potentially oily or heavy on the skin, depending on your personal preference and skin type.

• Will it be too oily? At 70%, it is highly likely to feel oily or very rich for most people, even though the oil itself is lightweight. The perception of oiliness is subjective.
• Will it dry quickly? Caprylic/Capric Triglyceride absorbs well, but at such a high percentage, the overall absorption speed of the formula might be slower than a cream with a lower oil phase, as there is a large amount of emollient to be absorbed or remain on the skin surface.
• How to make it less oily/sticky? The most effective way to reduce the oily and potentially sticky feel is to decrease the percentage of Fractionated Coconut Oil (Caprylic/Capric Triglyceride) in your formula. You could replace some of the oil phase with other ingredients that modify the texture, such as:
  • Reducing the total oil phase and increasing the non-oil phase (if it's an emulsion).
  • Incorporating ingredients that provide a drier feel or matte finish, such as certain types of esters, silicones (if desired), or powders (like starches or silica) that can help absorb excess oiliness.

Ultimately, the best approach is to experiment by reducing the percentage of Caprylic/Capric Triglyceride gradually and testing the feel until you achieve the desired texture. The interaction with the other 30% of ingredients also plays a significant role in the final feel.
