IOTA 345 is a premium, volatile silicone fluid blend specifically formulated for advanced cosmetic and personal care applications. Its INCI designation is Cyclopentasiloxane and Cyclohexasiloxane, combining the desirable properties of both cyclic silicones (D5 and D6) into a single, high-performance ingredient.

Description & Key Characteristics:
This colorless, transparent fluid offers a unique sensory profile and functional benefits. It is characterized by its bright appearance, exceptionally smooth texture, and complete non-greasy feel. A key technical advantage of IOTA 345 is its lower volatility compared to standard cyclopentasiloxane (D5), resulting in enhanced performance. Crucially, this lower volatility translates to no unpleasant cold sensation upon skin application and ensures it does not leave long-lasting residues on skin or hair, due to its lower vapor heat.

Technical Specifications:

• Appearance: Colorless transparent fluid

• Refractive Index (25°C): 1.3900 - 1.4050

• Specific Gravity (25°C): 0.950 - 0.970

• Viscosity (cSt, 25°C): 3.0 - 8.0

Distinctive Features:

1. Excellent Emulsification: Readily forms stable emulsions.

2. Broad Compatibility: Demonstrates outstanding compatibility with a vast range of cosmetic oils, esters, mineral oils, isopropanol, and higher viscosity silicones, enabling versatile formulation.

3. Clean Evaporation: Volatilizes effectively without lingering on skin or hair.

Consumer Benefits:

1. Superior Sensory Experience: Delivers a light, non-oily feel with absolutely no cold touch upon application.

2. Enhanced Feel: Imparts an exceptionally smooth, silky, and luxurious texture to both skin and hair.

3. Volatile Carrier: Acts as an elegant, temporary carrier that evaporates cleanly.

Primary Applications:
IOTA 345 is ideally suited for a wide spectrum of products seeking superior spreadability, a refined silky finish, and residue-free volatility. Key applications include:

• Skin care creams, lotions, and serums

• Hair care conditioners, serums, and styling products

• Massage creams and oils

• Antiperspirants and deodorants

• Color cosmetics (foundations, primers)

Usage Guidelines:
IOTA 345 can be used effectively as the sole volatile silicone or blended with other cosmetic fluids (e.g., mineral oils, isopropanol, vegetable/nutritional oils) to create stable solutions. It is also excellent for diluting high-viscosity silicone oils to improve spreadability and reduce tackiness. The recommended usage level typically ranges from 1% to 20%, depending on the desired sensory properties and formulation requirements. Its compatibility and ease of use make it a valuable and versatile ingredient for sophisticated cosmetic chemists.
