Sodium Phosphate salts are safe food-grade ingredients used in skin care products for pH adjustment, preservation, penetration enhancement, and emulsion stabilization.
Inorganic compounds
You may have heard of mineral sunscreens, sulfur for acne treatment, or miraculous clay face masks. These skin care products are based on inorganic compounds and minerals. Some inorganic compounds cannot penetrate dermal layers, yet do an excellent job on the skin's surface. E.g. main ingredients of mineral sunscreens are Zinc Oxide and Titanium Oxide.
Others are well absorbed and influence aspects of the skin from within: interaction with skin antioxidant enzymes, influence on collagen production, and antibacterial activity turn minerals into strong advocates of the firm and flourishing skin.
Sodium sulfite is a sodium salt of sulfurous acid, an inorganic compound used in skin and hair care formulas for balancing pH and as a preservative, reducing agent, and antioxidant.
Sulfur is a yellow crystalline inorganic elemental mineral used in skin and hair care applications for centuries. It is a time-honored ingredient valued for its exfoliating, antimicrobial, and sebum regulating properties.
Sulfur Plus is a complex based on sulfur that is solved in ethoxydiglycol. Sulfur is a known keratolytic, sebum regulator, and antiseptic used since ancient times.
Zinc Oxide acts as a photocatalyst absorbing and scattering UVA & UVB and converts UVR to heat and light that has a rejuvenating effect on skin connective tissue.
Zinc Sulfate (ZnSO4) is a great source of Zinc2+ ions that have an important role in the metabolism of epidermal proteins and the generation of natural moisturizing factors. It is also a potent sunscreen reflecting UV rays from the surface of the skin.
