Carbomer 940

INCI Name: Carbomer
Molecular Formula: (C₃H₄O₂)n
Alternative Names: Carboxyvinyl polymer, Acrylic acid polymer
Country of Origin: China

Description:

Carbomer 940 is a white, fluffy powder used to thicken, gel, or stabilize cosmetic and personal care products. It is a high-efficiency polymer that can create clear gels and give a smooth texture to creams and lotions. When neutralized, it forms a gel-like consistency that can hold and suspend ingredients. Carbomer 940 is widely used in skincare, haircare, and pharmaceutical products due to its versatility and safety.

Benefits and Uses:

• Thickens products – helps turn liquids into gels or creams.
• Stabilizes formulas – keeps ingredients mixed and prevents separation.
• Creates clear gels – ideal for transparent skincare products like hand sanitizers and facial gels.
• Improves texture – makes creams and lotions feel smooth and easy to apply.
• Suspends ingredients – holds particles, oils, or actives evenly in the formula.
• Works in many products – used in gels, creams, lotions, shampoos, and serums.

Carbomer 940 is popular in cosmetic formulations because it can make thick, stable, and pleasant-feeling products even at low usage levels. It does not need heat to work, which helps in making products with heat-sensitive ingredients. When combined with neutralizers like Triethanolamine (TEA) or Sodium Hydroxide, it swells in water to form smooth gels. This makes it especially useful in leave-on skincare products, hair styling gels, and pharmaceutical gels. Its versatility and ability to give a luxurious feel have made it a common choice for both commercial and handmade beauty products.

Concentration and Solubility:

• Recommended use level: 0.1% to 1% depending on desired thickness.
• Soluble in water; requires neutralization to form a gel.

How to Use:

• Mix slowly into water to prevent lumps.
• Neutralize with TEA or other alkalis to achieve desired gel texture.
