How to Use AccessSIL A-1709 in Your Formulations

Understanding AccessSIL A-1709

AccessSIL A-1709 is a specialized hair conditioning ingredient that belongs to the amodimethicone family. Think of it as a smart conditioner: while regular conditioners coat the entire hair fiber, this ingredient carries a slight positive charge and is drawn to the negatively charged, damaged areas of the hair shaft. The result is targeted conditioning exactly where it is needed most, without heavy buildup on healthier areas.

For the chemistry-minded: Bis-Aminopropyl Dimethicone is an amine-functionalized silicone. At typical hair-care pH, the amino groups are protonated (cationic), allowing strong ionic interaction with anionic sites on damaged cuticles. This high molecular weight polymer then forms a durable, smooth film on the hair surface, providing long-lasting conditioning, protection, and premium sensory benefits.

Expect significantly improved wet and dry combing, a luxurious soft and silky feel, and superior frizz control—all hallmarks of high-performance, salon-quality formulations.

Formulation Tips

Recommended usage is 0.5% to 5%. Use 0.5–1.5% for lightweight leave-ins or fine hair, 1–3% for daily conditioners, and up to 5% for deep-repair masks and intensive treatments.

Add AccessSIL A-1709 during the cool-down phase (below 40°C / 104°F), after your emulsion has formed. Avoid adding it to hot oil or water phases to prevent destabilizing the emulsion. Stir gently until fully and uniformly dispersed.

It pairs exceptionally well with fatty alcohols (e.g., Cetyl or Cetearyl Alcohol) and cationic conditioning agents (e.g., Behentrimonium Chloride) to build rich, robust conditioners. It is stable across typical hair-care pH (4–7) and is compatible with most common hair-care actives and extracts.

Key Formulation Benefits:

Superior Detangling & Combability: Provides exceptional slip on wet and dry hair, lowering combing force and reducing breakage.
Targeted Damage Repair: Deposits preferentially on damaged areas to smooth lifted cuticles and restore a healthy, hydrophobic feel without over-coating.
Exceptional Softness & Silky Feel: Delivers a luxurious, long-lasting softness and non-greasy, salon-like finish.
Effective Frizz Control: Forms a lightweight protective film that helps resist humidity, tame flyaways, and maintain a polished look.
Color & Heat Protection: Helps protect color vibrancy and provides a barrier against thermal styling stress.
Easy to Formulate: Simple cool-down addition enables quick sensory upgrades in conditioners, masks, and leave-ins.

Use 1–3% for daily conditioners. For a light leave-in spray or fine hair, 0.5–1.5% works well. For intensive masks and deep repair, go up to 5%.

Bis-Aminopropyl Dimethicone provides “smart” conditioning—depositing more on damaged areas and less on healthy regions—delivering excellent performance with reduced risk of heavy buildup.

Add during the cool-down phase, after your emulsion has formed and the batch is below 40°C (104°F). Stir gently until uniformly mixed.

Yes. For curls, it offers great slip and frizz control. For fine hair, keep usage lower (around 0.5–1.5%) to maintain lightness while adding softness and manageability.

No. It is not water-soluble, which enables a persistent conditioning film on hair. It still formulates easily into water-based conditioners and is removed by standard shampoos with mild surfactants.
