Maltodextrin is an organic sugar derived from corn, rice, or potato. It is a multipurpose ingredient. It is a skin softener, absorbent, and film-forming agent. But mostly it’s used because of its viscosity-controlling effect. It makes the product feel even. It is ruled safe by CIR for use in cosmetics.

Phenoxyethanol
Roles: Fragrance, Preservative
Antiseptic
Phenoxyethanol is one of the most popular preservatives. It kills bacteria and makes the product live longer. Manufacturers like this ingredient because it can dissolve in any liquid, even in oils.
Another purpose of this component is the fixation of aromas in perfumery. Phenoxyethanol is also used as a strong antiseptic and a good antibacterial agent. It is widely used in dermatological cosmetics alongside natural antiseptics such as chamomile, sage, and calendula.
Lecithin is a great emulsifier. It also has slight antioxidant activity, but it’s not enough if you are looking for a strong and effective anti-oxidant. Our skin cells contain Lecithin and that’s why this component will hardly cause any problems or negative reactions. It soaks in pretty fast and it’s accepted by skin cells very well.

Carbomer
Roles: Emulsion stabilizer, Gel forming, Viscosity controlling
Moisturizing
Carbomer is used for formulation purposes. It helps to control the viscosity and flow of a product. It’s considered safe but only if it’s well purified. Poorly purified carbomers may contain benzol which may lead to irritation.
Sodium Hyaluronate is an amazing component! It plays very important role in skin hydration process. It helps to maintain water balance and lower water loss. Scientists have found a direct dependence between the level of Sodium Hyaluronate in cells and skin aging. That's why this component is so much important. It must be in your routine if you want to have a healthy and fresh looking skin.
Some people think that Sodium Hyaluronate and Hyaluronic acid are different names of the same component, but it is not entirely correct. Hyaluronic acid is a different chemical but with similar effects. Actually, Sodium Hyaluronate is used in cosmetics much more often because it’s more stable and has much better resistance to oxidation.
Sodium Hydroxide is used mostly for formulation purposes. It helps to hold the pH level of a product. It also works as a chemical exfoliator that removes dead cells. Usually concentration of this component is low in skin care products and it’s used mostly for adjusting pH.

Tocopheryl Acetate is a form of Vitamine E. It’s used as an alternative to Tocopherol because it is more stable in the formulation. It has all the positive effects of Tocopherol plus better stability. It’s a brilliant component. It conditions and nourishes the skin helping it to resist aging. It also helps to protect the skin from the sun. High concentrations of Tocopheryl Acetate can lead to irritation and allergic reactions.

Potassium Phosphate
Roles: Buffering
Potassium Phosphate is an inorganic salt commonly used in cosmetics and skincare formulations. While it’s not a “hero ingredient” like niacinamide or ceramides, it plays important supporting roles that help a product stay stable, comfortable on the skin, and effective.
Potassium Phosphate (often listed as Dipotassium Phosphate or Monopotassium Phosphate depending on its form) is a buffering and chelating agent. In skincare chemistry, it helps regulate and maintain a product's pH balance — a crucial factor for both stability and skin compatibility. It helps to achieve PH balance by preventing the formula from becoming too acidic or too alkaline over time.
Main Functions:
pH Buffering Agent - Its primary purpose is to stabilize pH. Many active ingredients — such as niacinamide, ceramides, or hyaluronic acid — perform best within a particular pH range. Potassium Phosphate ensures they stay effective throughout the product’s shelf life.
Stabilizer for Emulsions - In creams and lotions, it helps maintain the stability of emulsions (the blend of water and oils), preventing unwanted separation.
Enhances Product Comfort - A stable pH often means better skin tolerance. By keeping the formula balanced, Potassium Phosphate indirectly helps reduce the risk of stinging, redness, and irritation, especially in sensitive skin.
Supports Ingredient Performance - Some actives can lose potency if the formula drifts out of range. Potassium Phosphate keeps the environment optimal, protecting their performance.

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.
