Processing Methods & Reference Formulations
A. Cosmetic moisturizers
When adding Propylene Glycol in cosmetic creams, incorporate it into the water phase to ensure even distribution and prevent separation. Use at 3–10% concentration as a humectant and solvent to improve skin hydration and product texture. Add it after heating to preserve its stability. Mix thoroughly to achieve a smooth, consistent formulation.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water | 65% |
| Propylene Glycol | 5% |
| Cetearyl Alcohol | 4% |
| Glyceryl Stearate | 3% |
| Mineral Oil | 8% |
| Stearic Acid | 3% |
| Dimethicone | 2% |
| Preservative (e.g., Phenoxyethanol) | 0.8% |
| Fragrance | 0.2% |
| Xanthan Gum | 0.5% |
| Glycerin | 8.5% |
B. Hair shampoo
Use Propylene Glycol in the aqueous phase to improve scalp hydration and enhance the solubility of active ingredients in shampoos.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Laureth Sulfate | 8-12% |
| Cocamidopropyl Betaine | 4-8% |
| Propylene Glycol | 1-8% |
| Glycerin | 2-4% |
| Water | 50-60% |
| Preservatives, Fragrance/Essential Oil, Other actives |
C. Face Washes
When adding Propylene Glycol in face wash formulations, include it in the water phase for uniform mixing and to enhance solubility of actives. Use at 1–8% to boost hydration and improve skin feel without stickiness. Add after surfactants to maintain clarity and prevent foaming issues. Mix gently to preserve product stability and texture.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Deionized Water | 50% |
| Glycerin | 15% |
| Propylene Glycol | 15% |
| Polysorbate 20 | 15% |
| PEG-150 (Polyethylene Glycol 6000) | 2% |
| Sucrose Cocoate | 0.7% |
| Sorbitol | 0.7% |
| Sodium Stearoyl Lactylate | 0.5% |
| Sodium Citrate | 0.5% |
D. Makeup foundation lotion
In foundation lotion formulation, add Propylene Glycol to the water phase early on to act as a humectant and solvent. Ensure it is fully dissolved before emulsification to enhance texture, pigment dispersion, and skin feel.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Stearic acid | 2% |
| Cetyl alcohol | 4% |
| Paraffin liquid | 20% |
| Dimethicone | 5% |
