Processing Methods & Reference Formulations
A. Cosmetic cream
Dissolve allantoin in the water phase and heat to ensure complete solubility. Avoid adding during the cool-down phase, as it has limited solubility in cold water and may recrystallize.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water (Aqua) | 70% |
| Glycerin | 5% |
| Cetearyl Alcohol | 4% |
| Caprylic/Capric Triglyceride | 6% |
| Isopropyl Myristate | 3% |
| Stearic Acid | 2% |
| Triethanolamine (TEA) | 0.8% |
| Benzalkonium Chloride (50% sol.) | 0.2% |
| Allantoin | 0.5% |
| Panthenol (Pro-Vitamin B5) | 1% |
| Tocopheryl Acetate (Vitamin E) | 0.5% |
| Dimethicone | 2% |
| Fragrance | 0.5% |
| Phenoxyethanol & Ethylhexylglycerin | 1% |
| Citric Acid (10% solution) | 0.4% |
B. Hair shampoo
Add allantoin to the heated water phase to ensure proper dissolution, as it has low solubility in cold water. Mix well to avoid grittiness or sediment in the final shampoo.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Primary surfactants | 8-12% |
| Secondary surfactants | 2-5% |
| Butters | 20-40% |
| Allantoin | 0.1–1% |
| Water | 40-50% |
| Other UV Filters, Antioxidants, Humectants, Fragrance/flavor etc. |
C. Facial Cleansers
When formulating facial cleansers, dissolve Allantoin (typically 0.1–0.5%) in the water phase by heating to ensure full solubility. Avoid overheating, as Allantoin can degrade at high temperatures. Stir gently to maintain clarity in clear formulations.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Deionized Water | 70% |
| EDTA-2Na | 0.10% |
| Sodium Cocoamphoacetate | 10% |
| Cocamidopropyl Betaine | 8% |
| Glycerine | 5% |
| Lauryl Glucoside | 4% |
| Panthenol | 1% |
| Allantoin | 0.3% |
D. Sunscreen cream
When adding allantoin to sunscreen, dissolve it in the water phase at 0.05–0.5% concentration and heat gently to ensure full solubilization. Maintain final pH between 5.0–7.0 for stability and compatibility with UV filters. Stir thoroughly to ensure uniform dispersion.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Homosalate | 6-10% |
| Ethylhexyl Methoxycinnamate | 5-9% |
| Ethylhexyl Salicylate | 2-6% |
| 4-Methylbenzylidene Camphor | 2-5% |
| Titanium Dioxide | 2-6% |
| Polydimethylsiloxane | 3-8% |
| Propylene Glycol | 3-6% |
| Allantoin | 0.05% to 0.3% |
| Plant extracts (e.g., safflower extract) | 0.3-0.6% |
| Emulsifiers and thickeners |
