The purpose of non-scented perfume is to provide an alternative to scented perfumes for those who are sensitive to fragrances or those who simply prefer no scent. Non-scented perfumes are formulated to have no smell but can contain ingredients that have a smell that has been neutralized by other components. It is important to note that “non-scented” does not necessarily mean “fragrance-free”, as some products labelled as non-scented may still contain masking fragrances or fragrance chemicals used to neutralize unpleasant odours from other ingredients. Fragrance-free products, on the other hand, do not contain any ingredients added solely to impart an aroma, although they may still have a scent from ingredients that serve other purposes, such as essential oils added for their moisturizing properties.

'Unscented' products are formulated to have no smell, but may contain ingredients with scents that have been neutralised
The term "non-scented perfume" is somewhat of a misnomer, as perfumes are typically defined by their scent. However, "non-scented" or unscented products are formulated to have no smell, or at least no noticeable scent. This means that they do not have an obvious aroma and are generally considered to have a neutral scent, neither pleasant nor unpleasant.
Unscented products are designed to have no smell, but they may still contain ingredients with scents. These scents are often neutralised or masked by other components. For example, an unscented product might contain lavender, but a chemical is added to mask the smell of lavender, so the product can be labelled as "unscented". This is distinct from fragrance-free products, which cannot contain any ingredients added to impart a smell, although they may still have a scent from naturally fragrant ingredients.
The distinction between "unscented" and "fragrance-free" is important, as some people may have allergies or sensitivities to certain fragrances. Common fragrance ingredients that can cause irritation include natural fragrances like chloroatranol and atranol (found in oakmoss and tree-moss fragrances), geraniol (an essential oil), and cinnamaldehyde (found in cinnamon trees). Synthetic fragrances can also cause issues, with some people finding natural citrus scents derived from essential oils irritating, for example.
Unscented products may contain masking fragrances or chemicals that neutralise the smell of other ingredients, such as fatty acids, fatty oils, and surfactants. Common masking agents include benzyl alcohol, benzoate, citronellol, limonene (citrus), lanolin, and essential oils (vanilla, peppermint, citrus). These ingredients serve to neutralise or cover up the scent of other ingredients, allowing the product to be labelled as "unscented".
In summary, "unscented products" are formulated to have no noticeable smell, but they may still contain ingredients with scents that have been neutralised or masked by other components. This is different from "fragrance-free" products, which cannot contain any added fragrances, although they may still have a scent from naturally fragrant ingredients.

'Fragrance-free' products do not contain ingredients added to impart a smell, but may contain ingredients with a scent
The purpose of non-scented perfume, or fragrance-free products, is to avoid the addition of scented compounds that may cause allergies or skin irritation. However, it is important to note that "fragrance-free" does not necessarily mean that the product is completely devoid of any scent.
Fragrance-free products do not contain ingredients added solely to impart a smell. However, they may still contain ingredients with inherent scents, such as natural oils or other compounds, that serve a functional purpose in the product's formulation. For example, a cream containing scented lavender oil as an emollient could still be labelled as fragrance-free because the oil is included for its moisturising properties rather than its scent.
On the other hand, "unscented" products are formulated to have no noticeable scent, neither pleasant nor unpleasant. These products often contain masking agents or neutralizers to eliminate or reduce the intensity of the inherent scents of other ingredients. For instance, an unscented antiperspirant deodorant might include fragrance chemicals to neutralize the odour of its active ingredients, resulting in a neutral or mild scent.
The distinction between fragrance-free and unscented products is important, especially for individuals with sensitive skin or allergies. While fragrance-free products avoid the use of added perfumes or scents, they may still contain naturally scented ingredients. Unscented products, on the other hand, aim to eliminate all noticeable scents, even if some fragrant compounds are present.
It is worth noting that the terminology surrounding fragrance-free and unscented products can be confusing and is not always used consistently by manufacturers. In some cases, products labelled as fragrance-free may still contain fragrance chemicals, as highlighted by a study that found 45% of best-selling moisturizers labelled "fragrance-free" contained such chemicals. Therefore, it is important for consumers, especially those with sensitivities or allergies, to carefully review ingredient lists and look for certification badges, such as the EPA's Safer Choice Fragrance-Free label, to make informed choices.

Fragrances can cause skin reactions like contact dermatitis, redness, itching, inflammation, and hives
Fragrances can cause skin reactions such as contact dermatitis, redness, itching, inflammation, and hives. Contact allergies to fragrances often cause dermatitis of the hands, face, and neck, as well as patches of skin where perfumes are commonly applied, such as behind the ears, the upper chest, elbow flexures, and wrists. The severity of dermatitis can range from mild to severe with dissemination.
Skin patch testing is typically used to determine whether a substance is causing allergic skin inflammation (allergic contact dermatitis). During this test, patches containing allergens are placed on the skin of the arm or back, and the skin is exposed to extracts of substances that can cause contact dermatitis for 48 hours. Skin responses are evaluated after 48 hours and again between 72 and 96 hours for delayed hypersensitivity reactions.
Fragrance allergies are a chronic condition that affects up to 4.5% of the general adult population and involves abnormal immune reactions to ordinarily harmless substances in fragranced products. These allergies typically occur when fragrance components called allergens come into contact with the skin, triggering the immune system to produce protective proteins called antibodies, resulting in an inflammatory response and allergy symptoms.
While true allergies involve the immune system, some people may experience irritation from exposure to certain substances without provoking an immune response. Intolerance to fragrances typically occurs in reaction to strong fragrances or large quantities, whereas allergies can be triggered by trace amounts.
To avoid skin reactions, individuals with sensitive skin or a desire to avoid perfumes should look for products labeled "fragrance-free." However, it is important to note that even products labeled as fragrance-free may still contain fragrance chemicals or compounds with a scent added for a purpose other than imparting a fragrance. On the other hand, unscented products are formulated to have no smell but can contain ingredients with neutralized scents or masking fragrances to eliminate undesirable odors from other ingredients.

Fragrances can be added to products to serve purposes other than scent, such as moisturising
The purpose of non-scented perfume is often misunderstood. While it is marketed as "unscented", it does not necessarily mean that the product is free of fragrance chemicals. Instead, it means that the product has a neutral scent, neither noticeably pleasant nor unpleasant. These products often contain chemicals that eliminate or mask undesirable scents of other ingredients used in the production process.
"Fragrance-free" products, on the other hand, are defined by the FDA as those that do not contain any ingredients added to impart a smell. However, this does not mean that the product won't have a smell. Fragrance additives can be included in a "fragrance-free" product if they serve a purpose other than giving the product a scent, such as moisturising. For example, rose oil may be included for its moisturising properties, despite its natural scent.
It is important to understand the difference between these terms, especially for those with sensitive skin or allergies. While unscented products may seem like a safer choice, they may still contain masking fragrances that can cause skin reactions or irritate those with fragrance sensitivities. Therefore, if one has sensitive skin or wants to avoid perfumes, it is recommended to look for products labelled "fragrance-free".
However, it is worth noting that even products labelled "fragrance-free" may still contain fragrance compounds. This is because shampoos, lotions, and moisturisers are treated as cosmetics rather than medicines, resulting in less strict regulations. Additionally, some companies use the term "fragrance-free" loosely, adding fragrance chemicals to their products despite the label.
In conclusion, fragrances can indeed be added to products to serve purposes other than scent, such as moisturising. However, it is important to be aware of the potential presence of fragrances in both "unscented" and "fragrance-free" products, especially for those with skin sensitivities or allergies.

Fragrances can be derived from natural or synthetic sources
The purpose of non-scented perfume is to provide a fragrance-free option for individuals with sensitive skin or those who want to avoid perfumes. These products are labelled "fragrance-free" and do not contain any ingredients added to impart a smell. However, they may still have a scent from other ingredients present in the product.
Synthetic fragrances, on the other hand, are developed in laboratories to replicate natural accords without causing harm to the environment. They offer longer-lasting scents with increased vitality due to the use of fixatives. Synthetics provide perfumers with more control over the scent's performance and allow for the protection and repopulation of natural sources. However, some people may prefer natural fragrances despite their limitations due to personal preferences or concerns about the use of chemicals.
The choice between natural and synthetic fragrances depends on individual needs and preferences. Natural fragrances are often sought after for their unique, evolving scents and potential health benefits, while synthetic fragrances offer consistency, longevity, and environmental advantages.
It's worth noting that the distinction between natural and synthetic fragrances is not always clear-cut, as some fragrances combine both elements. Additionally, the skill and intentions of the perfumer play a significant role in the final scent, regardless of the source of the fragrances.
