Improving Texture and Absorption of Oil Blend Formulation
คำถาม
I have an oil blend formulation and want to improve its texture and absorption, as it feels oily and doesn't absorb well. The base formula is:
- Shea butter 60%
- Jojoba 10%
- Sweet almond 10%
- Evening primrose 10%
- Rose hip oil 8%
- Silicone Gel Base (Ultra Clear) 2%
I tried adding Water-Capsule™ and Silicone Gel (Ultra Clear, Super Silky) but the product still feels oily and doesn't absorb well. How can I modify the formula to achieve a better texture and absorption?
คำตอบ
Understanding Your Oil Blend Formulation
Your current formula, consisting of 100% oils and butters (Shea butter, Jojoba, Sweet almond, Evening primrose, Rose hip oil), is very liquid and feels oily on the skin because it lacks ingredients that help it absorb or change its texture.
Why Pure Oils Feel Oily and Don't Absorb Well
The outermost layer of our skin is naturally water-based. Oils, being hydrophobic (water-repelling), do not easily penetrate this layer on their own. When you apply a pure oil blend, it tends to sit on the surface, creating a greasy feel and slow absorption.
Why Adding Water-Capsule™ or Silicone Gel Didn't Work
You attempted to improve the texture by adding Water-Capsule™ and Silicone Gel (Ultra Clear, Super Silky). However, these ingredients are used in specific ways to create different formula structures:
- Water-Capsule™: This is a Water-in-Oil (W/O) emulsifier. It's designed to create emulsions where tiny water droplets are dispersed within an oil phase. This requires a significant amount of water in the formula (often the majority) and a limited oil phase (Water-Capsule™ works best with 5-20% oil). Simply adding 2% to a 100% oil blend won't create the necessary emulsion structure.
- Silicone Gel (Ultra Clear, Super Silky): This product is primarily used to improve spreadability and provide a smooth, silky feel. While it can be mixed with oils and silicones, it is not an emulsifier that can bind oil with water. Adding a small percentage to your oil blend won't fundamentally change its oily nature or improve absorption into the water-based skin surface.
How to Improve Texture and Absorption
To make your product less oily and absorb better, you need to change the fundamental structure of the formula. This typically involves creating an emulsion (like a cream or lotion) or an oil gel, which requires adding an emulsifier and often a water phase.
The staff's suggestions point to the correct approach:
- Create an Oil Gel: Use a suitable gelling agent or emulsifier (like certain Sucrose esters, e.g., Sucrose Cream Maker™) that can thicken the oil phase and potentially incorporate a small amount of water.
- Create a Cream (Oil-in-Water): Use an O/W emulsifier to disperse the oil phase within a continuous water phase. This results in a non-greasy, easily absorbed texture but requires a significant amount of water (more than oil).
- Create a Water-in-Oil Cream: Use a W/O emulsifier (like Water-Capsule™ or SiliSolve Plus™) to disperse water within the oil phase. While the external phase is oil, these can be formulated for good absorption and skin feel, but they still require a water phase and the oil phase needs to be within the emulsifier's capacity (e.g., max 20% oil for Water-Capsule™).
Conclusion
To achieve the desired texture and absorption, you cannot simply add a small amount of an ingredient to your existing 100% oil blend. You need to reformulate the product by incorporating an appropriate emulsifier and a water phase to create a stable emulsion or an oil gel structure. Products like Water-Capsule™, SiliSolve Plus™, or Sucrose esters (such as Sucrose Cream Maker™, Sucrose Stearate, or Sucrose Palmitate) are examples of ingredients used to create these different formula types, but they require a complete formulation approach, not just simple addition to pure oil.
