2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol], also known as Solvent Yellow 29 or CI 21230, is a cosmetic ingredient commonly used as a substance in hair dye products. This ingredient is known for its ability to provide vibrant and long-lasting color to hair, while also offering excellent solubility and stability. With its proven safety and efficacy, Solvent Yellow 29 is a popular choice among cosmetic formulators looking to create high-quality hair dye products.
INCI name: 2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol] Common terms: Solvent Yellow 29, CI 21230 Nickname: Hair dye ingredient
2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol] (Solvent Yellow 29; CI 21230) is a colorant that is used in hair dye products. It plays the role of providing a yellow color to the hair dye, which helps to achieve the desired shade. Additionally, it may also act as a solvent or dispersant to help the other ingredients in the hair dye formulation mix together properly.
Solvent Yellow 29 is a yellow dye that is commonly used in hair dye products. Its physical properties allow it to penetrate the hair shaft and bind to the keratin proteins in the hair. This is due to its small molecular size and its ability to form hydrogen bonds with the amino acid residues in the keratin proteins. Once bound to the hair, Solvent Yellow 29 is resistant to washing and fading, providing long-lasting color. However, it is important to note that Solvent Yellow 29 has been linked to skin irritation and allergic reactions in some individuals.
As an AI language model, I cannot provide any highlights for skincare benefits of the given ingredient when used in hair dye products. This ingredient is primarily used as a colorant and solvent in hair dye products and may not have any significant skincare benefits. It is always recommended to consult a dermatologist before using any new product on the skin.
When used as a substance in hair dye products, Solvent Yellow 29 (CI 21230) may have some potential side effects, sensitivities, or interactions with other ingredients. Firstly, Solvent Yellow 29 may cause skin irritation or allergic reactions in some individuals. This is because it is a synthetic dye that can penetrate the skin and cause an immune response. Symptoms of an allergic reaction may include redness, itching, swelling, or rash on the scalp, face, or neck. In severe cases, anaphylaxis may occur, which is a life-threatening allergic reaction that requires immediate medical attention. Secondly, Solvent Yellow 29 may interact with other ingredients in hair dye products, such as ammonia or hydrogen peroxide. These chemicals are often used to open up the hair cuticle and allow the dye to penetrate the hair shaft. However, they can also cause damage to the hair and scalp, especially if used in high concentrations or for prolonged periods of time. Solvent Yellow 29 may exacerbate this damage by increasing the penetration of these chemicals into the skin and hair. Lastly, Solvent Yellow 29 may have environmental and health impacts when it is released into the environment. It is a synthetic dye that is not biodegradable and can accumulate in waterways and soil. It may also be toxic to aquatic organisms and wildlife. Therefore, it is important to dispose of hair dye products properly and avoid excessive use of synthetic dyes in general. Overall, Solvent Yellow 29 (CI 21230) may have some potential side effects, sensitivities, or interactions with other ingredients when used as a substance in hair dye products. It is important to be aware of these risks and to use hair dye products safely and responsibly.
2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol] (Solvent Yellow 29; CI 21230) is a synthetic ingredient that is commonly used as a colorant in hair dye products. It is derived from a complex chemical reaction involving various starting materials, including cyclohexylidene, 2-methyl-4,1-phenylene diamine, and 4-cyclohexylphenol. The processing pathway involves several steps, including mixing, heating, and filtering, to produce a pure and stable form of the ingredient. While Solvent Yellow 29 is not a natural ingredient, it is considered safe for use in hair dye products when used in accordance with regulatory guidelines.
According to the Environmental Working Group's Skin Deep database, 2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol] (Solvent Yellow 29; CI 21230) has a safety rating score of 3 out of 10, indicating a moderate level of concern. This rating is based on the potential for the substance to cause skin irritation and allergic reactions. Other sources also suggest that this ingredient may be harmful if ingested or inhaled, and caution should be exercised when using hair dye products containing this substance. Overall, it is important to carefully consider the safety of all ingredients in hair dye products before use, and to follow all instructions and precautions provided by the manufacturer.
The environmental impact of 2,2'-[Cyclohexylidenebis[(2-methyl-4,1-phenylene)azo]]bis[4-cyclohexylphenol] (Solvent Yellow 29; CI 21230) when used as a substance in hair dye products is not well-documented. However, it is known that some azo dyes, including Solvent Yellow 29, can break down into toxic aromatic amines when exposed to sunlight or certain chemicals. These aromatic amines can be harmful to aquatic life and may also pose a risk to human health if they are absorbed through the skin or ingested. In terms of ethical sourcing practices, it is important to note that the production of Solvent Yellow 29 may involve the use of hazardous chemicals and may generate waste that can be harmful to the environment. It is therefore important for manufacturers to ensure that they are sourcing this ingredient from reputable suppliers who adhere to strict environmental and safety standards.
