Formulation Compatibility
Compatible with:
- Most natural and synthetic oils (jojoba, squalane, caprylic/capric triglycerides, etc.)
- Silicones (cyclomethicone, dimethicone)
- Non‑ionic emulsifiers (glyceryl stearate, ceteareth‑20, polysorbates)
- Common preservatives (phenoxyethanol, ethylhexylglycerin, potassium sorbate)
- UV filters (zinc oxide, titanium dioxide, avobenzone, octinoxate, octocrylene)
Avoid or test carefully:
- Strong alkaline conditions (pH > 8.0)
- Direct contact with metal ions (iron, copper) – may catalyze oxidation and cause discoloration
- High concentrations of strong pro‑oxidants (unlikely in typical cosmetics)
Sample Formulation: Simplified O/W Sunscreen Lotion (SPF ~15–20)
This is a basic emulsion to demonstrate incorporation. For commercial SPF products, combine with other filters.
| Phase | Ingredient | % w/w |
|---|---|---|
| A (Oil) | Feruloyl Soy Glycerides | 4.0 |
| A | Octinoxate (ethylhexyl methoxycinnamate) | 2.0 |
| A | Avobenzone (butyl methoxydibenzoylmethane) | 2.0 |
| A | C12-15 Alkyl Benzoate | 5.0 |
| A | Glyceryl Stearate + PEG-100 Stearate | 4.0 |
| A | Cetearyl Alcohol | 1.0 |
| B (Water) | Deionized Water | to 100 |
| B | Glycerin | 3.0 |
| B | Xanthan Gum | 0.2 |
| B | Disodium EDTA | 0.1 |
| C | Preservative (e.g., phenoxyethanol) | q.s. |
Procedure:
- Heat Phase A to 70–75°C with stirring until uniform.
- Heat Phase B to 70–75°C, ensuring xanthan gum is fully hydrated.
- Add Phase B to Phase A with homogenization (3000–5000 rpm for 2–3 minutes).
- Cool to 40°C with gentle stirring.
- Add preservative (Phase C) and mix until uniform.
- Adjust pH to 5.5–6.0 if needed.
Frequently Asked Questions (FAQ)
Q1: Can Feruloyl Soy Glycerides be used in cold‑process formulations?
Yes, as long as the oil phase is liquid at room temperature. Add to the oil phase before emulsification.
Q2: Will it cause yellowing in the final product?
Unlike free ferulic acid, Feruloyl Soy Glycerides does not readily turn yellow under normal storage or UV exposure, provided the formulation is protected from metal ion contamination.
Q3: Can it replace octinoxate entirely?
Not entirely, but it can partially replace octinoxate (e.g., replace 1–2% of octinoxate) while maintaining or even improving photostability.
Q4: Is it suitable for natural/clean beauty claims?
Yes. It is plant‑derived (soybean oil), produced via enzymatic green chemistry, and carries USDA BioPreferred certification.
Q5: What documentation do you provide?
Each shipment includes COA, MSDS, TDS, allergen and GMO statements, preservative efficacy test reports, and stability data upon request.
Conclusion
Feruloyl Soy Glycerides is a versatile, clean, and high‑performance active that simplifies formulation while delivering multi‑functional benefits – UV enhancement, antioxidant defense, anti‑photoaging, and protection of other sensitive actives.
