Ethanol 70% is a widely used alcohol that serves multiple purposes in cosmetics and personal care products.
It is often used as a solvent for other ingredients, in preservation systems to enhance antimicrobial activity, and as a quick-drying base in sanitising gels and toners.
At this concentration, ethanol is ideal for creating formulations that require both effective disinfection and skin-friendly comfort, especially in hand sanitizers and facial toners.
FEATURES
- Antimicrobial properties – effective at killing bacteria and viruses, often used in sanitizing products.
- Solvent – dissolves various actives, extracts, and fragrance oils.
- Quick-drying – evaporates quickly, leaving no residue on skin.
- Versatile – used in a wide range of cosmetic and personal care products.
BEST FOR
- Hand sanitizers
- Facial toners
- Solvent-based formulations
- Disinfectant sprays
- Deodorant sprays
- Hair care (as a solvent for extracts)
FORMULATION GUIDELINES
| INCI | Ethanol |
|---|---|
| Type | Solvent and preservative (antimicrobial) |
| Solubility | Soluble in water and most alcohol-based systems |
| Use Rate | 5–70% typical, depending on intended use. 60–70% for effective sanitizing; 10–30% for use in toners or as a solubilizing agent. |
| pH Compatibility | Works well in formulations with a pH range of 4.0–7.0. |
| Temperature Tolerance | Stable under normal processing conditions. Avoid excessive heat or prolonged exposure to high temperatures during formulation. |
| Pro Tip | Use ethanol 70% as a base for sanitizing or deodorising sprays. In toners, combine with other soothing or hydrating ingredients to balance its drying effect. Ensure good ventilation during formulation, as ethanol evaporates quickly and should be mixed in well-ventilated areas. |
| Appearance | Clear, colourless liquid |
| Stability Notes | Stable at room temperature. Avoid exposure to heat and air, as prolonged exposure to oxygen and light can reduce its efficacy. |
| Storage | Keep sealed, cool, and dry. Store away from heat sources and open flames. |
