Aqua/Water/Eau is simply the term used for water in cosmetic formulations. It's primarily used as a solvent in cosmetics, meaning it's used to dissolve many of the other ingredients that make up a product. When you see Aqua/Water/Eau listed in the ingredients of a product, it's typically referring to purified water - free of toxins, pollutants and microbes.

Most cosmetics contain a large amount of water (often 70-80% of the total), making it the most commonly used ingredient in such products. The water used in cosmetics can be of different types, such as distilled water, mineral water, or thermal water, which all offer various properties and benefits.

Here are some of the key functions of water in cosmetic products:

Solvent: As mentioned, water acts as a solvent for many ingredients, helping to dissolve them and make a homogeneous solution.
Humectant: Water also acts as a humectant, meaning it helps to retain or preserve moisture. This is why it's often used in products like moisturizers, lotions, and creams.
Diluent: Water is used as a diluent to reduce the concentration of other ingredients. This is particularly useful when dealing with potent substances that might cause irritation or other issues if used undiluted.
Carrier: Water can act as a carrier, helping to spread other ingredients across the skin.
Rehydration: Water can also rehydrate dry or dehydrated skin and hair, providing a feeling of freshness and comfort.

Salicylic Acid is a beta hydroxy acid (BHA) derived from willow bark, and it is commonly used in cosmetic formulations for its exfoliating and anti-inflammatory properties. It works by dissolving the bonds between dead skin cells, promoting cell turnover and revealing fresher, smoother skin. Salicylic Acid is particularly effective in treating acne-prone and oily skin, as it penetrates deep into the pores to unclog them and reduce sebum production. Additionally, it can help to reduce the appearance of fine lines, wrinkles, and uneven skin tone. In cosmetic formulations, Salicylic Acid is often found in cleansers, toners, spot treatments, and peels.

Sodium Hydroxide, also known as lye or caustic soda, is an inorganic compound with the chemical formula NaOH. It is a strong alkaline substance that is commonly used in cosmetic formulations for various purposes.In cosmetics, Sodium Hydroxide serves primarily as a pH adjuster and buffering agent. It helps to maintain the stability and effectiveness of a product by controlling its acidity or alkalinity. This is important because the pH level of a product can affect its performance, safety, and skin compatibility.Some common use cases of Sodium Hydroxide in cosmetic formulations include:1. Soap making: Sodium Hydroxide is a key ingredient in the traditional process of saponification, where it reacts with oils or fats to create soap. This reaction produces glycerol and a sodium salt of the fatty acid, which forms the soap.2. Hair relaxers: Sodium Hydroxide is used in hair relaxer formulations to break the disulfide bonds in the hair's keratin structure, allowing the hair to be straightened.3. Exfoliants: In some cosmetic formulations, Sodium Hydroxide is used in low concentrations to create a mild exfoliating effect on the skin, helping to remove dead skin cells and promote a smoother complexion.4. Emulsifiers: Sodium Hydroxide can be used to neutralize fatty acids, creating emulsifying agents that help to stabilize oil-in-water or water-in-oil emulsions in cosmetic products.It is important to note that Sodium Hydroxide should be used with caution in cosmetic formulations, as it can be highly caustic and irritating to the skin and eyes at high concentrations. Formulators must ensure that the final product has a safe and appropriate pH level for its intended use.
