Rose & Geranium Natural Facial Toner

Citric acid is a naturally occurring alpha-hydroxy acid (AHA) found in citrus fruits and widely used in skincare formulations. This versatile ingredient serves multiple purposes in dermatological products, primarily as a pH adjuster and mild exfoliant. Its ability to lower the pH of formulations helps stabilize other active ingredients and enhance product efficacy.

As an exfoliant, citric acid gently removes dead skin cells, promoting cell turnover and improving skin texture. This action can help reduce the appearance of fine lines, uneven skin tone, and mild hyperpigmentation. Additionally, citric acid possesses antioxidant properties, offering some protection against free radical damage.

In skincare, citric acid is typically used in concentrations ranging from 0.5% to 2%, depending on the product's intended purpose. It's often found in cleansers, toners, serums, and chemical peels. While generally well-tolerated, individuals with sensitive skin should introduce citric acid-containing products gradually to assess tolerance.

Beyond its exfoliating and antioxidant benefits, citric acid can enhance the skin's moisture retention capabilities and aid in the absorption of other active ingredients. Its multifunctional nature makes it a valuable component in various skincare formulations targeting diverse skin concerns.

Polysorbate 20 is a versatile and widely used emulsifier in skincare and cosmetic formulations. This non-ionic surfactant is derived from sorbitol and ethylene oxide, resulting in a clear, viscous liquid at room temperature. Its primary function is to stabilize oil-in-water emulsions, allowing for the seamless blending of water-soluble and oil-soluble ingredients in a single product.

In skincare applications, Polysorbate 20 serves multiple purposes. It acts as a solubilizer, helping to dissolve fragrances and essential oils into water-based formulations. This property makes it invaluable in creating homogeneous and stable products. Additionally, it functions as a mild cleansing agent and can enhance the spreadability of creams and lotions.

The ingredient's low potential for skin irritation makes it suitable for a wide range of skin types, including sensitive skin. Polysorbate 20 also exhibits some moisturizing properties, contributing to the overall efficacy of skincare formulations. Its ability to improve the texture and feel of products on the skin further enhances its appeal in cosmetic formulations.

Regulatory bodies, including the FDA and EU Cosmetics Regulation, have deemed Polysorbate 20 safe for use in personal care products at current concentration levels.

Potassium sorbate is a widely used preservative in skincare and cosmetic formulations, recognized for its effectiveness against yeasts and molds. This white, crystalline powder is the potassium salt of sorbic acid, a naturally occurring compound found in some berries. In skincare products, potassium sorbate functions primarily to extend shelf life and maintain product integrity by inhibiting microbial growth.

With a pH range of 4.5-6.5, potassium sorbate is particularly suitable for slightly acidic formulations. It exhibits broad-spectrum antimicrobial activity, especially against fungi, while being less effective against bacteria. This preservative is often used in conjunction with other antimicrobial agents to provide comprehensive protection against various microorganisms.

Potassium sorbate is generally considered safe for use in cosmetics and is approved by regulatory bodies worldwide. It is non-irritating and non-sensitizing for most individuals, making it suitable for a wide range of skin types. The ingredient is water-soluble and typically used at concentrations of 0.1-0.5% in skincare formulations. Its efficacy can be influenced by factors such as pH, water activity, and the presence of other ingredients in the product.
