Kerastase Laque Couture Medium Hold - Ingredient Explanation
Alcohol Denat
1. Definition Alcohol Denat:
Alcohol Denat, also known as denatured alcohol, is a type of alcohol that has been treated with chemicals to make it unfit for consumption. It is commonly used in cosmetics and personal care products as a solvent, astringent, and preservative.2. Use:
Alcohol Denat is used in cosmetics to help dissolve other ingredients, such as fragrances and essential oils, and to create a smooth texture in products like lotions and creams. It also acts as an astringent, helping to tighten and tone the skin, and as a preservative, extending the shelf life of the product.3. Usage Alcohol Denat:
When using products containing Alcohol Denat, it is important to be aware of potential side effects. Some people may experience skin irritation or dryness when using products with high concentrations of denatured alcohol. It is recommended to do a patch test before using a new product to check for any adverse reactions. Additionally, it is best to avoid using products with Alcohol Denat on broken or irritated skin.4.

Hydrofluorocarbon 152a
1. Definition Hydrofluorocarbon 152a:
Hydrofluorocarbon 152a, also known as HFC-152a, is a colorless, odorless gas commonly used as a propellant in aerosol products. It is a type of hydrofluorocarbon that does not deplete the ozone layer, making it a more environmentally friendly alternative to chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).2. Use:
Hydrofluorocarbon 152a is primarily used as a propellant in aerosol products such as hairsprays, deodorants, and air fresheners. It helps to create a fine mist or spray that allows these products to be easily dispensed from their containers. Additionally, HFC-152a is also used in certain cosmetic formulations to provide a cooling or tingling sensation on the skin.3. Usage Hydrofluorocarbon 152a:
When using products containing Hydrofluorocarbon 152a, it is important to follow the instructions provided on the packaging. Avoid spraying the product near open flames or sources of heat, as HFC-152a is flammable. Do not puncture or incinerate aerosol containers, as this can release the gas in a dangerous manner. It is also recommended to use these products in a well-ventilated area to prevent inhalation of the gas.4. References:

Butane
1. Definition Butane:
Butane is a highly flammable, colorless gas that is commonly used as a propellant in aerosol products, including cosmetics. It is a hydrocarbon with the chemical formula C4H10.2. Use:
Butane is used in cosmetics to create the pressure necessary to propel products out of aerosol containers, such as hairsprays, deodorants, and shaving creams. It helps to deliver the product in a fine mist or foam form, making it easier to apply evenly.3. Usage Butane:
When using cosmetics containing butane, it is important to follow the instructions on the product label carefully. It is recommended to use these products in a well-ventilated area, away from sources of heat or flame. Avoid inhaling the gas directly and do not puncture or incinerate the aerosol container. In case of skin irritation or respiratory problems, discontinue use and seek medical attention.4. References:

Va Crotonates/ Vinyl Neodecanoate Copolymer
1. Definition Va Crotonates/ Vinyl Neodecanoate Copolymer:
Va Crotonates/ Vinyl Neodecanoate Copolymer is a copolymer formed by the polymerization of vinyl acetate and neodecanoic acid. It is commonly used in cosmetics as a film-forming agent and binder.2. Use:
Va Crotonates/ Vinyl Neodecanoate Copolymer is used in cosmetics to improve the texture and consistency of products. It helps to create a smooth and even application, as well as providing long-lasting wear. This copolymer is often found in products such as foundations, mascaras, and lipsticks.3. Usage Va Crotonates/ Vinyl Neodecanoate Copolymer:
When using products containing Va Crotonates/ Vinyl Neodecanoate Copolymer, it is important to follow the instructions provided by the manufacturer. Avoid getting the product in contact with the eyes, and discontinue use if any irritation or adverse reactions occur. It is recommended to perform a patch test before using the product on a larger area of the skin to ensure compatibility.4. References:
