Glycerin is a naturally occurring non-toxic alcohol that can be derived both from plants as well as animal fat. Glycerin used in The Proper Soap Company soaps is always plant based and is a by-product of soap production process called saponification. Saponification is the process during which fat or oil are transformed into soap and alcohol.
Glycerin has moisturising properties and it’s been used as soap ingredient for centuries. It can lock moisture on skin, as well as absorb moisture from the atmosphere. Due to those properties, you might find that our soaps sometimes form a layer of moisture before use. This is the effect of glycerin and it is completely normal.
All our soaps are based on vegetable glycerin.

Limonene is a naturally occurring compound that is present in citrus fruits. It is chemically classified as cyclic monoterpene and it comes in a form of clear liquid. It is most commonly used in perfumes and soap, but also other personal care products. Through oxidation it can degrade to products that were found to be irritants and sensitizers. Hence for those with sensitive skin, it is recommended to avoid products with Limonene in them or seek advice from a medical professional first.
Limonene is present in most of our soap bars.
Linalool is a terpene alcohol that occurs naturally in plants and is present in many essential oils such as orange, lavender, rose, rosewood, and coriander. Due to its pleasant floral smell it is used as fragrance ingredients in cosmetic products. According to online sources, Linalool is used in 60 - 80% of products such as soaps and shampoos.

Sodium Palm Kernelate
Sodium Palm Kernelate is a sodium salt of acid that is derived from palm kernel oil. It is a very efficient cleansing agent but it is also used as surfactant, emulsifier as well as agent increasing viscosity. It is obtained during the process of combining palm kernel oil with hydroxide. Palm kernel oil is obtained from the same plant as palm oil but instead of the palm fruit it is derived from the seed of the Elaeis Guineensis plant - the same plant from which palm oil is derived. Our soaps contain only RSPO (Roundtable For Sustainable Palm Oil) certified palm oil and palm oil derivatives.
Sodium Palmate is sodium salt of fatty acids derived from Elaeis guineensis - the same plant that provides palm oil. It is created during the saponification process where the fatty acids contained in palm oil react with hydroxide. In soaps it is used as surfactant and emulsifying agent.

It is a surfactant that thanks to its anionic composition acts as a cleansing agent making it easier to wash dirt from skin and hair. It is also a foaming agent. Contrary to what it may seem, Disodium Lauryl Sulfosuccinate is not a sulfate but its milder non-irritant alternative.

SLES is derived from SLS to form a milder alternative that is usually well tolerated on sensitive skin.
Sodium Stearate is a non-toxic sodium salt of stearic acid which is a naturally occurring fatty acid. Sodium Stearate is plant based and can be derived from coconut oil or palm oil. It is a surfactant that acts as a cleansing and emulsifying agent. It has the ability to create thickness for various cosmetic products.
Titanium Dioxide is a naturally occurring oxide of titanium. In its pure form, it is a white powder that has been widely used in a variety of products such as cosmetics, toothpaste, soap, as well as food colorants. It is mainly used as a pigment to achieve white colour of products. Titanium Dioxide has long been a subject of safety debate due to concerns raised over its carcinogenic effect. There has however, not been any conclusive studies confirming this, and the risk has only been identified concerning products that are aerosolised (airborne) and where inhalation is a concern. Titanium Dioxide used in our soaps has low skin penetration and there is no risk of inhalation. In addition, according to opinion published by European Commission Scientific Committee, Titanium Dioxide has a low to zero risk of skin irritation, eye irritation, and a weak to non-skin sensitisers.
