D&C Yellow No. 11 Oil Soluble is a variant of the D&C Yellow No. 11 dye, designed to be soluble in oils, rather than in water. This makes it suitable for use in oil-based formulations like lipsticks, lip glosses, and other products that require an oil-soluble colorant.
Description:
- D&C Yellow No. 11 Oil Soluble is a yellow colorant derived from synthetic sources, typically coal tar.
- It is used to impart a yellow or golden color to products that are oil-based.
- This form is specifically designed to be soluble in oils and fats, unlike the water-soluble form of D&C Yellow No. 11, which is used in aqueous formulations.
- CAS Number: 630-10-7 (the same as D&C Yellow No. 11)
- Color Index Number (CI): 47000.
Appearance:
- Typically appears as a fine powder or granular form, which is mixed into oil-based formulations to create vibrant yellow shades.
Usage Rate:
The usage rate for D&C Yellow No. 11 Oil Soluble is generally lower compared to water-soluble versions because oil-based formulations are more concentrated in terms of color stability and intensity.
-
Typical Usage Rate: Generally, the usage rate for D&C Yellow No. 11 Oil Soluble is 0.01% to 0.5% depending on the product and desired intensity of color.
- In Lip Products (like lipsticks, glosses): The colorant concentration is often between 0.05% to 0.2%.
- In Other Oil-based Cosmetics (e.g., body oils, lotions): Concentrations can range from 0.01% to 0.5%, depending on the formulation.
Applications:
-
Cosmetics:
- Lipsticks and Lip Glosses: The oil-soluble nature allows for a vibrant yellow or golden hue in these formulations.
- Eyeshadow: Sometimes used in oil-based eyeshadows or eyeliners.
- Face Powders: Can be added to oil-based foundations or face powders for color effects.
-
Pharmaceuticals:
- Used to color ointments, creams, or capsules that are oil-based.
-
Personal Care Products:
- Body Oils, Shampoos, or Conditioners: Often added to create visually appealing products.
Safety and Regulation:
- D&C Yellow No. 11 Oil Soluble is FDA-approved for use in cosmetics and pharmaceuticals but is not approved for use in food products.
- The usage of this dye is tightly regulated in cosmetic formulations, and the FDA recommends concentrations typically not exceeding 0.5% in finished products.
Considerations:
- Since it is oil-soluble, it is primarily used in products where the base is oil, wax, or fat, and would not dissolve well in water-based formulations.
- Like all synthetic colorants, it is recommended to follow the guidelines set forth by regulatory bodies like the FDA for safe usage.
In summary, D&C Yellow No. 11 Oil Soluble is a yellow dye designed for use in oil-based cosmetic and pharmaceutical products, with typical usage rates ranging from 0.01% to 0.5%, depending on the desired shade intensity and product type.
