Decyl Glucoside
Roles: Cleansing, Emulsion stabilizer, Surfactant
Cleansing
Decyl glucoside is a surfactant. It provides degreasing and wetting effects. It removes dirt and sebum gently. It doesn’t irritate the skin but at the same time, it’s an effective cleanser. It’s considered to be the safest among all the other surfactants.
Glycerin is one of the most outstanding and helpful skincare components. It's used in many skincare products because it works and provides notable results. It's one of the best moisturizers. Molecules of Glycerin can absorb water and deliver it into deep layers of the skin making it hydrated.
Benzyl Alcohol doesn’t belong to harmful alcohols and it will not dry your skin. It’s a stabilizing agent that prevents ingredients oxidization. Having this component in formulation the product will keep efficiency for a longer time. Benzyl Alcohol has a slight almond odor and is used as a fragrance ingredient very often.
Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.
It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.

Antiseptic
Sodium Benzoate doesn’t have any great skincare effects and is used for formulation purposes. It’s a corrosion inhibitor, fragrance ingredient, and preservative. It is not a broad-spectrum preservative and it’s used with other preservatives for good efficiency. It’s safe, but people with eczema or a history of skin allergies should use this component with attention.
Potassium Sorbate is a preservative that increases the shelf life of the product. It’s a great alternative to parabens. That's why manufacturers like to use this component. It is safe in concentration of up to 10% but it is used in cosmetics in amounts of 1% or even lower.

Fragrances
Fragrance is a mix of chemical ingredients (usually 20-30 chemicals but up to 200 sometimes) that help the product to smell better. It can hide many bad things. Synthetic fragrances may contain many different chemicals, but manufacturers don’t want to reveal each of them for some reason and hide them behind the word "Fragrance".
