FAQ (Frequently Asked Questions)
1. What is NanoEmo PEG-400?
NanoEmo PEG-400 is an advanced, nano-emulsified form of traditional Polyethylene Glycol 400 (PEG-400). Engineered with the aid of Sodium Alginate as a stabilizing and emulsifying agent, this new format improves solubility, skin absorption, and delivery of active ingredients in cosmetic and skincare products.
2. What is the role of Sodium Alginate in NanoEmo PEG-400?
Sodium Alginate acts as a natural stabilizer and rheology modifier. In NanoEmo PEG-400, it facilitates the formation of stable nanoemulsions, ensuring uniform particle dispersion, enhanced bioavailability, and improved skin feel. It also contributes to the product's eco-friendly and clean-label appeal.
3. How does NanoEmo PEG-400 differ from conventional PEG-400?
Compared to standard PEG-400, NanoEmo PEG-400:
Has reduced particle size for better skin penetration
Improves delivery of actives into deeper skin layers
Enhances the stability of emulsions and suspensions
Offers a smoother, more luxurious texture
Performs effectively at lower concentrations
4. Why was PEG-400 reformulated into NanoEmo PEG-400?
The reformulation aligns with trends toward high-performance, science-backed skincare solutions. NanoEmo PEG-400 offers advanced functionality in line with clean beauty expectations and allows formulators to reduce the quantity of synthetic emulsifiers while improving efficacy and user experience.
5. What are the benefits of using NanoEmo PEG-400 in personal care products?
Enhanced penetration of active ingredients
Improved solubility for hydrophilic and lipophilic compounds
Stable nanoemulsion base for a wide range of formulations
Lightweight, non-greasy feel on the skin
Clean-label formulation support via natural stabilizers
6. In what types of personal care products can NanoEmo PEG-400 be used?
NanoEmo PEG-400 is ideal for:
Serums and facial oils
Lotions and creams
Hair conditioners and treatments
Body mists and sprays
Makeup bases and primers
Sun care and after-sun products
7. What is the CAS number and INCI name of PEG-400?
CAS Number: 25322-68-3
INCI Name: PEG-400 (Polyethylene Glycol 400)
Note: NanoEmo PEG-400 may carry additional technical descriptors, but it retains the same INCI classification under most cosmetic regulatory frameworks.
8. Is NanoEmo PEG-400 safe for topical use?
Yes, NanoEmo PEG-400 is safe for use in cosmetic and personal care formulations. It maintains the low-irritation, non-toxic profile of conventional PEG-400, and the addition of Sodium Alginate enhances its biocompatibility and eco-safety.
9. Is NanoEmo PEG-400 compatible with other skincare ingredients?
Absolutely. NanoEmo PEG-400 is highly compatible with a variety of ingredients including botanical extracts, vitamins (e.g., Vitamin C and E), essential oils, hyaluronic acid, and sunscreens. Its nano-format enhances synergistic effects when used with actives.
10. How do I incorporate NanoEmo PEG-400 into my formulations?
NanoEmo PEG-400 is typically added during the aqueous or emulsification phase. It is recommended to stir gently at controlled temperatures to preserve nanoemulsion integrity. Dosage can range from 1% to 5%, depending on the formulation type and desired function.
