Adjusting Your Makeup Remover Formula for a Non-Sticky Feel

It sounds like you're looking to achieve a lighter, smoother feel with your makeup remover formula, similar to Bioderma Sensibio H2O. The sticky residue you're experiencing is a common issue with water-based formulas containing humectants like Glycerin, although at 1% in your formula, Glycerin is less likely to be the sole cause. The overall balance of ingredients contributes to the final skin feel.

Comparing your formula to the Bioderma Sensibio H2O ingredient list provides some clues for modification. The Bioderma product contains several ingredients not present in your current mix that can improve the skin feel:

• Propylene Glycol or Butylene Glycol: These are solvents and humectants that can help reduce stickiness and improve the glide and feel of the product on the skin. Butylene Glycol is often considered milder.
• Mannitol, Xylitol, Rhamnose, Fructooligosaccharides: These sugar alcohols and saccharides can contribute to a smooth, conditioned feel on the skin, counteracting tackiness.
• Cetrimonium Bromide: Primarily a hair conditioner, it can also impart softness to the skin and has preservative properties.
• Disodium EDTA: A chelating agent used for stability.

To modify your formula to reduce stickiness and achieve a cleaner, smoother feel, consider adding ingredients from the Bioderma list known for improving skin feel:

1. Add a Glycol: Incorporate 2-5% of Butylene Glycol or Propylene Glycol. Butylene Glycol (Product ID 320) is a good option. Pentylene Glycol (Product ID 2132) is another alternative solvent with moisturizing benefits.
2. Add a Sugar Alcohol or Saccharide: Include 1-3% of an ingredient like Mannitol (Product ID 1400), Rhamnose (Product ID 770), or Fructooligosaccharide (Product ID 7755). These can enhance the smooth, non-sticky finish.
3. Consider Disodium EDTA: Adding 0.1-0.2% Disodium EDTA (Product ID 184) can help with formula stability, as seen in the Bioderma list.

Here is a potential adjusted formula structure:

• Water: 80-83%
• MakeUp-Wash (PEG-6 Caprylic/Capric Glycerides) (Product ID 373): 10%
• Cucumber Extract (Product ID 219): 2%
• Glycerin (Product ID 143): 1% (or slightly less, e.g., 0.5%)
• Phenoxyethanol SA (Preservative) (Product ID 928): 1%
• Butylene Glycol (Product ID 320) or Propylene Glycol (Product ID 138) or Pentylene Glycol (Product ID 2132): 3-5%
• Mannitol (Product ID 1400) or Rhamnose (Product ID 770) or Fructooligosaccharide (Product ID 7755): 1-3%
• Disodium EDTA (Product ID 184): 0.1-0.2% (Optional)

Experiment with these additions in small test batches, adjusting the percentages within the suggested ranges until you achieve the desired clean and smooth feel on your skin.
