Skin Care Products Using Sodium Hydroxide: Safety Concerns and Potential Adverse Reactions
Sodium hydroxide, a white solid compound with a pH of 14, is a versatile substance found in various skincare and household products. This alkaline substance is used in the production of soap, hair dye, nail polish, face wash, body cream, and nail polish remover, in addition to soap and makeup.
While sodium hydroxide plays a crucial role in the formation and lathering of soap, it can be potentially dangerous if ingested or comes into contact with sensitive areas like the eyes or skin. If ingested, sodium hydroxide can cause lung inflammation, throat swelling, intense abdominal pain, severe change in blood pH, and difficulty breathing. In high concentrations, it can cause chemical burns, hives, and holes in the skin, and may lead to vision loss if it gets in your eyes.
However, in skincare products, the amounts of sodium hydroxide used are generally considered safe. It is often used as a pH adjuster or cleansing agent, helping to establish and maintain the pH of a product. This is important, as the skin's typical pH range is between 4 and 7. Sodium hydroxide also helps stabilize and maintain a skincare product's pH.
Despite its widespread use, it's crucial to exercise caution when using products containing sodium hydroxide, especially for those with sensitive skin or skin conditions like eczema, psoriasis, cystic acne, or rosacea. It's advisable to consult a dermatologist before making any major changes to your skincare routine.
A patch test should be performed before using sodium hydroxide products to check for any adverse reactions. Common skin symptoms caused by sodium hydroxide include rash, hives, itching, redness or discoloration, irritation, flaking skin, and increased sensitivity.
Pure sodium hydroxide can damage your skin, so it's important to use gloves when handling concentrated amounts used in oven and drain cleaners. Sodium hydroxide is also used in cleaning products like oven cleaners, drain cleaners, detergents, paper, and aluminum.
In the realm of skincare, sodium hydroxide can be found in makeup, cleansers, soaps, and facial and body care products. While specific brands like Dermasence, NUXE, La mer, PHYRIS, Eau Thermale Avène, and others produce creams and cleansers containing sodium hydroxide, the exact presence of this ingredient in their products was not explicitly detailed in the available search results.
In conclusion, while sodium hydroxide is a common ingredient in various skincare and household products, it's essential to use these products responsibly and with caution. Always consult a dermatologist, perform a patch test, and use protective measures when handling concentrated amounts.
