Body Oil Formulation: Emollient Classification and Structural Frameworks

Question

How should Emollients be classified into 5 types specifically for a Body Oil that is fast-absorbing yet moisturizing? Additionally, regarding the formulation of 5 main Body Oil categories: Perfume Body Oil: Focused on long-lasting fragrance. Glow and Dew Body Oil: Focused on a dewy, healthy-looking glow. Dry Touch Body Oil: Focused on fast absorption without stickiness. Nighttime Body Oil: Focused on deep nourishment during sleep. Sunscreen Body Oil: For daytime use in conjunction with primary sunscreens. Please provide a structural framework based on these 6 core components: Main Oil Texture Modifiers (Oils or Esters) Natural Oils Active Ingredients (e.g., incorporating BHT and Ascorbyl Palmitate from the previous discussion) Fragrance and related substances Preservatives/Antioxidants How should the framework for each group be defined to ensure suitability for its specific purpose?

To create a body oil that is both fast-absorbing and deeply moisturizing, selecting the right combination of emollients is key. Here is the breakdown of the 5 types of emollients and the structural framework for the 5 body oil categories you mentioned.

1. 5 Types of Emollients for Fast-Absorbing & Moisturizing Body Oil

In the context of body oils, emollients can be categorized by their "weight" and functional role:

Ultra-Light/Dry Esters (The "Fast-Absorber"): These provide a "silicone-like" feel without using silicone. They disappear into the skin almost instantly, leaving a matte or satin finish.
- Example: LipidSoft™ Dry II or LipidSoft™ Lite.
Polar Esters (The "Solubilizer"): These are essential for dissolving fragrances, UV filters, and active ingredients like Vitamin C Ester (Ascorbyl Palmitate). They help the oil spread evenly.
- Example: LipidSoft™ C1215.
High-Gloss/Medium Esters (The "Dewy-Maker"): These provide the visual "glow" and a lingering sense of moisture without the heavy, sticky feeling of traditional oils.
- Example: LipidSoft™ Moist.
Natural Triglycerides (The "Nourisher"): These are natural oils that mimic skin lipids. They provide long-term barrier repair but can be greasy if used alone.
- Example: Fractionated Coconut Oil or Argan Oil.
Structured/Fixing Esters (The "Longevity-Booster"): These have higher viscosity or specific structures that help "fix" the fragrance to the skin or create a water-resistant film.
- Example: LipidSoft™ Fix.

2. Structural Framework for 5 Body Oil Groups

Here is how to balance the 6 components for each specific formula type:

Component	1. Perfume Body Oil	2. Glow & Dew	3. Dry Touch	4. Nighttime	5. Sunscreen
1. Main Oil (Base)	LipidSoft™ C1215 (High solubility)	LipidSoft™ Moist (High gloss)	LipidSoft™ Dry II (Ultra dry)	Fractionated Coconut Oil	LipidSoft™ C1215 (UV solvent)
2. Texture Modifier	LipidSoft™ Lite	LipidSoft™ C1215	LipidSoft™ Lite	LipidSoft™ Moist	LipidSoft™ Dry II
3. Natural Oil	Minimal (1-2%) to avoid rancidity	Moderate (5-10%) for richness	Very Low (1-2%)	High (20-40%) for deep repair	Low (2-5%)
4. Active Ingredients	Antioxidants (BHT/Vitamin E)	Mica/Shimmer + Vitamin E	Vitamin E	Vitamin C Ester, Vitamin A	OMC (UV Filter)
5. Fragrance & Fixatives	High (5-10%) + LipidSoft™ Fix	Moderate (1-2%)	Moderate (1-2%)	Relaxing Essential Oils	Moderate (1%)
6. Preservative/AOX	Oil-soluble + BHT	Oil-soluble + Vitamin E	Oil-soluble	Oil-soluble + Vitamin E	Oil-soluble

Formulation Tips:

For Perfume Oil: Use LipidSoft™ C1215 as the primary base because it can hold a high percentage of fragrance without separating and helps the scent last longer.
For Glow Oil: LipidSoft™ Moist is superior for creating a "healthy skin" shine that looks expensive and not just "oily."
For Nighttime Oil: This is where you should incorporate your Vitamin C Ester (Ascorbyl Palmitate). Use a small amount of a polar ester (like C1215) to help dissolve it before mixing it into the natural oil base.
Antioxidants: Always include Vitamin E (Tocopheryl Acetate) and BHT in every formula to prevent the natural oils and fragrances from oxidizing (turning rancid).
