Behenyl Alcohol
Description
Behenyl Alcohol is a saturated fatty alcohol of plant origin, used in cosmetics as a consistency agent, co-emulsifier, and opacifier. It distinguishes itself from other fatty alcohols (such as Cetyl or Cetearyl alcohol) through its specific sensory profile featuring a matte, non-greasy finish.
It imparts a sophisticated texture to cosmetic products and acts as a protective and moisturizing agent, making it an optimal ingredient in modern O/W (oil-in-water) formulations and for structuring stick-type products.
Ingredients: Behenyl Alcohol
Characteristics
- Solubility: Soluble in oils and lipids when heated; insoluble in water.
- Indicative Dosage: 1% - 10%
- Appearance: Cream-white granules or flakes, specific fine scent.
- Quality: 100% natural origin, derived from rapeseed, approved for organic cosmetics, biodegradable.
Main Properties
- Superior Consistency Factor: Increases the viscosity and stability of emulsions more effectively than shorter-chain alcohols, preventing phase separation at higher temperatures.
- Structuring and Viscosity Agent: Provides consistency to creams and lotions without making them heavy or sticky.
- Emulsion Stabilizer: Helps maintain the mixture between the water and oil phases, preventing ingredient separation over time.
- Velvety Sensation - Dry-Touch: Offers a matte finish and a non-greasy texture, being superior to cetyl or cetearyl alcohol regarding the final skin feel.
- Protective Barrier: Forms a fine, occlusive layer that prevents transepidermal water loss (TEWL), making it ideal for sensitive or dry skin.
- Plant Origin: Biodegradable product, approved by COSMOS standards for natural cosmetics.
Usage Recommendations
Behenyl Alcohol is extremely versatile and can be integrated into numerous personal care recipes.
- Face and Body Care: Face creams, hand and body lotions, eye contours, body butters, stick deodorants, and balms.
-
Hair Care: Conditioners and hair masks; provides manageability and reduces static/frizz effect.
-
Makeup Products: Lipsticks, creamy foundations, or concealer sticks.
-
Sun Protection: Sunscreens; increases the water resistance of SPF products and improves the dispersion of solar filters.
Formulation Guide
Recommended dosage: 1-5% for emulsions; 3-10% for dense creams and body butters; 10% or slightly more for stick-type products.
Incorporation method: Added to the oil phase of the preparation. It requires heating, as it has a melting point of approximately 65°C.
Compatibility: Stable across a wide pH range and can be combined with other emulsifiers or fatty alcohols to achieve customized textures.
Frequently Asked Questions (FAQ)
What is the difference compared to Cetyl alcohol or Cetearyl alcohol?
Behenyl Alcohol has a longer carbon chain (C22), which gives it a higher melting point and a less unctuous, drier, and more matte texture.
At what temperature should it be heated?
Since it has a melting point of around 65°C, the oil phase in which it is introduced should be heated up to 70°C, provided the formula does not contain ingredients requiring higher temperatures.
Is it a standalone emulsifier?
No, it is a co-emulsifier and consistency agent. It must be used together with a primary emulsifier to form a stable emulsion.
Safety in Use
The product is intended for cosmetic use. It is considered a safe, non-irritating, and non-sensitizing ingredient.
There are no special usage restrictions in cosmetic products. It is biodegradable and not ecotoxic.
Storage: Store in a cool, dry place, away from moisture and heat sources. Close the container tightly after use.
