  • Polyacrylamide: 9003-05-8
  • C13-14 Isoparaffin: 64742-46-7
  • Laureth-7: 3055-99-0
• Molecular Formula: Not applicable (Complex mixture of polymer, hydrocarbon solvent, and non-ionic surfactant)
• Specification:
  • Active Matter: ~30% (Polymer content)
  • pH (as is): 6.0 – 8.0
  • Viscosity: High viscosity gel
  • Solubility: Dispersible in water; forms stable emulsions with oil phases

• Ingredient Information: A pre-neutralized polyacrylamide copolymer dispersed in mineral oil (C13-14 Isoparaffin) and stabilized with Laureth-7. It functions as a non-ionic emulsifying thickener that allows for the creation of oil-in-water (O/W) emulsions without the need for additional emulsifiers or neutralizing agents.

Product Uses

Product Description:
Sepigel 305 is a revolutionary "3-in-1" ingredient that combines emulsification, thickening, and stabilization in a single step. Its primary advantage is the ability to formulate stable oil-in-water emulsions via a cold process, significantly reducing energy consumption and production time. It delivers a rich, creamy texture with excellent sensory properties, leaving the skin soft and non-sticky. The ingredient is highly robust across a wide pH range (3.0–12.0) and tolerates high levels of electrolytes and active ingredients, making it a favorite for modern, efficient cosmetic manufacturing.

Applications:
Sepigel 305 is widely used in various personal care products, including:

• Body Lotions & Creams: Daily moisturizers requiring quick absorption and non-greasy finish.
• Facial Care: Day/night creams, anti-aging serums, and sensitive skin formulations.
• Sun Care: Sunscreens and after-sun lotions due to its stability with UV filters.
• Baby Care: Gentle baby lotions and creams owing to its mild, non-ionic nature.
• Hair Care: Leave-in conditioners and styling creams.

Formulation Suggestions:
Recommended Usage: Typically used at 1.0% to 3.0% of the total formulation weight. For light lotions, 1.0–1.5% is sufficient; for richer creams, 2.0–3.0% is recommended.

Method of Addition:

• Cold Process: Add Sepigel 305 directly to the aqueous phase under moderate agitation. Once dispersed, slowly add the oil phase while mixing. Homogenize if necessary to achieve desired particle size and texture.
• Hot Process (Optional): Can also be added to the water phase at elevated temperatures (up to 70°C), but cold processing is preferred to maximize efficiency.
• Mixing: Avoid high-shear mixing for extended periods after emulsion formation to prevent viscosity breakdown.

Compatibility & Synergy:

• pH Tolerance: Stable in a broad pH range (3.0–12.0). No neutralization is required.
• Electrolytes: Highly tolerant to salts and ionic active ingredients, unlike traditional carbomers.
• Actives: Compatible with most cosmetic actives, including vitamins, extracts, and UV filters.
• Preservatives: Compatible with standard preservative systems. Note that high concentrations of certain alcohols may affect viscosity.
• Synergy: Can be combined with other thickeners (e.g., Xanthan Gum) for modified rheology, though often used alone for simplicity.
