Glycerin soap is distinct because of its high glycerin content, which is a natural byproduct of the soap-making process called saponification. When fats or oils are combined with a strong alkali (like lye) and water, the chemical reaction produces soap and glycerin.
There are a few ways "glycerin soap" can be made:
* Natural Glycerin Retention: All natural, handmade soaps (made via cold or hot process) will naturally contain glycerin. In commercial soap production, glycerin is often separated and sold for other products (like lotions) because of its value. So, a "glycerin soap" might simply be one where the natural glycerin is retained.
* Translucent/Clear Glycerin Soap: What many people commonly refer to as glycerin soap is often the translucent variety. This type of soap is made by continuously heating a soap mixture (from oils, water, and lye) with added alcohol and sugar. The alcohol prevents crystallization, and the added glycerin balances the drying effect of the alcohol, resulting in a clear, jelly-like consistency.
* Melt and Pour Bases: Many "melt and pour" soap bases, popular for DIY soap crafting, are essentially pre-made glycerin soap. They contain a higher amount of added glycerin to allow them to be easily melted and re-solidified.
What is Glycerin Soap Good For?
Glycerin soap is highly valued for its skin-friendly properties, primarily due to glycerin being a humectant. This means it attracts and holds moisture from the air, drawing it into the skin. This makes glycerin soap particularly beneficial for:
* Moisturizing Skin: It helps to keep skin hydrated and prevents dryness, making it excellent for those with dry, sensitive, or easily irritated skin.
* Gentle Cleansing: Unlike some harsher soaps that strip the skin of its natural oils, glycerin soap cleanses gently while helping to lock in moisture.
* Sensitive Skin: It's often recommended for sensitive skin because pure glycerin soap is typically free of alcohol, fragrances, and other harsh chemicals that can cause irritation.
* Skin Conditions: Its moisturizing and soothing properties can be beneficial for people with conditions like eczema, psoriasis, acne, and rosacea, as it can help reduce inflammation and prevent further drying.
* Anti-aging: By keeping skin hydrated and plump, glycerin can help reduce the appearance of fine lines and wrinkles.
* All Skin Types: Despite being highly moisturizing, it's generally non-greasy, making it suitable for oily and combination skin types as well.
