Btms-50 (Cosmetic)   

BTMS-50 (Cosmetic Grade) is a key ingredient in many hair and skin care formulations.

🔹 BTMS-50

• Full name: Behentrimonium Methosulfate (and) Cetyl Alcohol (and) Butylene Glycol.
• Type: A cationic (positively charged) emulsifier and conditioning agent.
• Comes as white to off-white waxy flakes or pellets.
• Widely used in conditioners, creams, lotions, and detanglers.
• The “50” refers to the concentration of active conditioning agent (50%).

🔹 Key Properties

• Emulsifier → blends oil and water into smooth creams/lotions.
• Conditioning agent → makes hair soft, silky, and manageable.
• Detangling effect → reduces frizz and improves comb-through.
• Lightweight → doesn’t leave heavy residue on hair or skin.
• Moisturizing → improves hydration without greasiness.

🔹 Cosmetic & Personal Care Uses

1. Hair Care

• Conditioners (rinse-off & leave-in).
• Hair masks & treatments → restores softness and shine.
• Detanglers & anti-frizz sprays.
• Suitable for all hair types, especially dry, curly, or damaged hair.

2. Skin Care

• Lotions & creams → give a silky, powdery finish.
• Body butters & moisturizers → improves spreadability.
• Facial creams → gentle enough for sensitive skin.

🔹 Typical Usage Rates

• Lotions & creams → 1–6%

👉 Always melted into the heated oil phase of a formulation.

🔹 Safety & Benefits

• Stable across a wide pH range (4–7).

🔹 BTMS-50 vs. BTMS-25
