| Catalog Number | CI-SC-0757 |
| Product Name | Aqua |
| CAS | 7732-18-5 |
| Description | Aqua is a term that refers to water, often used in the context of aquatic environments, ecosystems and organisms. Aqua is probably one of the most important ingredient used in cosmetic products. It is an odorless, tasteless, inorganic, transparent, and nearly colorless substance that occurs naturally on the Earth's surface. If the list of ingredients shows Aqua on the top - it almost definitely means that Aqua ingredient is present in more quantity than any other ingredient in the product. Based on the category, Water makes up almost 60-85% of the product. It may even go up to 95% in rinse-off products like shower gels and shampoos. However, some products like bar soaps and some makeup only contain traces of the ingredient Aqua. |
| Appearance | clear, colorless liquid |
| Application | Aqua is used as a solvent in various industrial processes such as in the production of dyes, pharmaceuticals, and cosmetics. |
Aqua, frequently listed as Aqua, Eau, or simply Water, is a fundamental component in the composition of most personal care products. While it may initially appear as a straightforward solvent for other ingredients, Aqua's essential role is highlighted by its influence on the sensory attributes, texture, and visual appeal of these formulations, as well as its purity, origin, and quality. Various types of water are utilized, chosen based on specific purity and origin criteria. Commonly used forms include purified, softened, and pH-balanced spring or mineral water, which contain trace mineral ions beneficial to the metabolic functions of skin, hair, and other tissues. In certain products, mineral water enriched with microelements like Zinc, Copper, Magnesium, and Iron ions is selected to enhance cell activity, strengthen natural defenses, and improve hydration. Distilled water, known as Aqua Destillata, is employed in formulations where higher purity is required, minimizing microbes and potentially reducing the need for preservatives. The most refined form is deionized water, which is preferred where the exclusion of ions or precise pH balance is critical, ensuring the stability and longevity of emulsions and suspensions through stable electrostatic interactions.
What role does Aqua play in personal care products?
Aqua, or water, serves as a fundamental ingredient in personal care products, acting as a solvent for other components. Its purity, origin, and quality significantly influence the product's sensory profile, texture, and appearance.
Are there different types of water used in personal care formulas, and how are they selected?
Yes, several types of water are utilized, selected based on their purity and origin. Commonly used types include purified, softened, and balanced spring or glacial water, which contain minerals beneficial for skin and hair. Mineral water, rich in elements such as Zinc, Copper, Magnesium, and Iron, is selected for its ability to enhance cellular activities and hydration. For formulations requiring higher purity, distilled water (Aqua Destillata) and deionized water are used to ensure minimal ion content and prevent microbial presence.
Why is distilled water used in some personal care formulations?
Distilled water is employed for its high purity level, which requires fewer preservatives and functional ingredients. It ensures formulations free from microbes and contains a lesser quantity of ions, ideal for products demanding controlled ionic environments.
What advantages does deionized water provide in cosmetic products?
Deionized water offers the highest purification, making it suitable for compositions requiring minimal ion content or specific pH balance. It supports stable emulsions and suspensions by reducing electrostatic repulsion, thereby extending product longevity and effectiveness.
How do mineral ions in water benefit personal care products?
Mineral ions present in certain types of water, such as Zinc, Copper, Magnesium, and Iron, contribute to enhanced dermal cell activity, improved natural defense mechanisms, and superior hydration. These microelements play vital roles in metabolic processes of the skin, hair, and other tissues, making them valuable inclusions in personal care formulations.
