BIS-DIGLYCERYL POLYACYLADIPATE-2 NEW

BIS-DIGLYCERYL POLYACYLADIPATE-2 is a complex, synthetic polymer (a polyester) widely used in the cosmetics and personal care industry. Its primary function is as a film-forming agent and emollient. It is particularly valued as a modern, innovative ingredient that provides a superior sensory experience, often serving as a plant-derived alternative to silicones and other synthetic film-formers.

Chemical Composition and Production

The name describes its structure and production:

• Diglyceryl: Refers to a subunit derived from glycerin (a sugar alcohol).

  Polyacyladipate: Indicates it is a polymer made from adipic acid (a dicarboxylic acid) and fatty acids ("acyl" refers to the fatty acid chains).

  Bis-: Implies a linking or bridging structure between two of these polymer chains.

In simpler terms, it is created by reacting biological-derived materials like glycerin and fatty acids (often from plant sources like rapeseed or castor oil) with adipic acid to form a large, flexible polyester molecule. This synthesis results in an ingredient that is often touted as being over 50% natural-origin.

Key Functions and Benefits

1. Film Formation:
This is its most critical property. It forms a very thin, flexible, continuous, and breathable film on the skin or hair. This film acts as a barrier that:

• Reduces Transepidermal Water Loss (TEWL): It effectively locks in moisture, making it an excellent hydrating agent.

  Provides Water Resistance: It enhances the durability and water resistance of products like sunscreens and long-wear makeup.

2. Emolliency:
It imparts an exceptionally smooth, silky, and luxurious feel to formulations. It fills in the micro-irregularities on the skin's surface, creating a velvety-smooth canvas.

3. Sensory Modifier:
It is renowned for its unique sensory properties. It delivers:

• Non-Greasy, Non-Occlusive Feel: It spreads easily and absorbs quickly without a heavy or sticky residue.

  "Soft Focus" Effect: The film can help to optically blur the appearance of fine lines and pores, similar to silicones.

  Significant Slip: It provides excellent lubricity, making products easy to blend.

4. Alternative to Silicones:
For brands marketing "clean" or "natural" beauty products, it is a popular alternative to dimethicone and other silicones, as it can mimic their desirable sensory benefits while being derived from biological sources.

Common Applications

You will find this ingredient in a wide range of high-performance cosmetics, including:

• Moisturizers & Creams: For long-lasting hydration and a smooth finish.

  Sunscreens: To improve water resistance and spreadability.

  Foundations & Primers: To create a pore-blurring, smooth base that improves makeup longevity.

  BB/CC Creams: For a blend of skincare and makeup benefits.

  Hair Care Products: In conditioners and serums to provide shine and reduce frizz without buildup.

Safety and Considerations

• Safety Profile: It is generally considered safe for topical use in cosmetics. It has a low potential for irritation and is non-comedogenic (does not clog pores).

  Regulation: It is approved for use in cosmetics and listed in the International Nomenclature of Cosmetic Ingredients (INCI).

In summary, BIS-DIGLYCERYL POLYACYLADIPATE-2 is a versatile, high-performance cosmetic polymer that effectively binds moisture to the skin, provides a luxurious sensory feel, and enhances the durability of formulations, making it a staple in modern skincare and makeup.
