Panthenol, also known as pro-vitamin B5, is well absorbed when applied topically to the skin and is rapidly oxidized enzymatically in the body to pantothenic acid (vitamin B5). Vitamin B5 is a component of coenzyme A, which is involved in various physiological processes such as intracellular lipid synthesis in the epidermis.(1-2) Panthenol penetrates the skin better than vitamin B5 and is very well tolerated.(1-3) Panthenol has a skin-caring and moisturizing effect and strengthens the skin's barrier function.(2-5) In dry skin, it compensates for the reduced hydration by increasing the water content and positively influencing the molecular mobility of the lipid lamellae and proteins of the stratum corneum and thus also reducing transepidermal water loss.(4-5) Panthenol can support wound healing in burns, burns, corneal lesions and allergic dermatitis in all three phases of wound healing and has a protective effect against skin irritation.(5-6)

Pentylene glycol is a chemical compound that is frequently used in cosmetic products. Due to its versatile functions, it is a valuable ingredient in the cosmetics industry. It can act as a humectant, solvent and skin and hair care product. In addition, pentylene glycol contributes to the improved stability of cosmetic products(1).

Phenoxyethanol is a preservative that has been used as a preservative in cosmetic products for decades. Phenoxyethanol has a broad spectrum of antimicrobial activity and is effective against various gram-negative and gram-positive bacteria as well as yeasts, with only a weak inhibitory effect on the resident skin flora.(1) According to the European Scientific Committee on Consumer Safety, phenoxyethanol is safe for all consumers (including children of all ages) when used as a preservative in cosmetic products up to a maximum concentration of 1%. It can be considered as one of the best tolerated preservatives in cosmetic products(1).

Phenylbenzimidazole Sulfonic Acid (PBSA) is a water-soluble, chemical UV filter with an absorption range between 280 and 320 nm. As a UVB absorber, PBSA specifically protects the skin from sun-related damage such as sunburn. It can be ideally combined with other UV filters(1).

Phenylpropanol is an organic compound that belongs to the group of aromatic alcohols and has a reliable antimicrobial effect.(1) In addition, phenylpropanol is a non-sensitizing substance that masks unpleasant raw material odors.(2)

Phytosphingosines belong to the sphingolipids, which occur naturally in the stratum corneum both in free form and as part of the main fraction of ceramides. Phytosphingosines are known to strengthen the skin barrier. In addition, phytosphingosines have a moisturizing effect by influencing the filaggrin signaling pathway and promote the formation of natural moisturizing factors.(1) Furthermore, phytosphingosines show excellent clinical results in acne skin care based on both anti-inflammatory and antimicrobial activity.(2-3)

Polyamide-8 is an oil-structuring polymer used in sun care and make-up products. It stabilizes pigment dispersions, improves durability and ensures a pleasant skin feel. Due to its film-forming properties, Polyamide-8 contributes to wear resistance and thus improves the abrasion resistance of the product(1).

Polyglycerin-3 is polymerized glycerin, which is used in cosmetic products to moisturize the skin. Due to its large molecular size, it penetrates the skin comparatively slowly and thus ensures long-lasting moisturization. It also forms a protective barrier, binds water and traps it in the upper layers of the skin. It is recommended for use in cosmetic products and was classified as safe in a safety assessment for cosmetic ingredients(1).
