Provençal ( / ˌ p r ɒ v ɒ̃ ˈ s ɑː l / , also UK : /- s æ l / , US : / ˌ p r oʊ -, - v ən -/ ; Occitan : provençau or prouvençau [pʀuvenˈsaw] ) is a variety of Occitan , spoken by people in Provence and parts of Drôme and Gard . The term Provençal used to refer to the entire Occitan language, but more recently it has referred only to the variety of Occitan spoken in Provence. However, it can still be found being used to refer to Occitan as a whole, e.g. Merriam-Webster states that it can be used to refer to general Occitan, though this is going out of use.

295-576: A part of the Ardèche , is not exactly a subdialect of Provençal, but rather a closely related Occitan dialect, also known as Vivaro-Alpine . So is the dialect spoken in the upper valleys of Piedmont , Italy ( Val Maira , Val Varaita , Val Stura di Demonte , Entracque , Limone Piemonte , Vinadio , Sestriere ). Some people view Gavòt as a variety of Provençal since a part of the Gavot area (near Digne and Sisteron) belongs to historical Provence. When written in

354-429: A perfume. Also, food flavourings, which have developed since the 1970s, account for over half of production output today. This represents almost half of the production of French perfumes and aromas and around 7-8% of total global activity. However, during the 1960s and 1970s large international groups gradually bought up local family factories (Chiris, Givaudan-Roure and Lautier, for example). Soon after their production

413-602: A program to certify functional claims based on third-party testing. Shampoos made for treating medical conditions such as dandruff or itchy scalp are regulated as OTC drugs in the US marketplace.

Thereafter, the product spread through the Royal Court and high society, and this made

531-511: A thick, viscous liquid. Other essential ingredients include salt ( sodium chloride ), which is used to adjust the viscosity, a preservative and fragrance . Other ingredients are generally included in shampoo formulations to maximize the following qualities: Many shampoos are pearlescent .

Glycol distearate

590-441: A type of moisturizing shampoo. Shampoo for infants and young children is formulated so that it is less irritating and usually less prone to produce a stinging or burning sensation if it were to get into the eyes.

These contain fungicides such as ketoconazole , zinc pyrithione and selenium disulfide , which reduce loose dander by killing fungi like Malassezia furfur . Coal tar and salicylate derivatives are often used as well. Alternatives to medicated shampoos are available for people who wish to avoid synthetic fungicides. Such shampoos often use tea tree oil , essential oils or herbal extracts.

1770-950: The better baby shampoos. Sulfate-free shampoos are composed of natural ingredients and free from both sodium lauryl sulfate and sodium laureth sulfate . These shampoos use alternative surfactants to cleanse the hair. Shampoo intended for animals may contain insecticides or other medications for treatment of skin conditions or parasite infestations such as fleas or mange . These must never be used on humans. While some human shampoos may be harmful when used on animals, any human haircare products that contain active ingredients or drugs (such as zinc in anti-dandruff shampoos) are potentially toxic when ingested by animals. Special care must be taken not to use those products on pets. Cats are at particular risk due to their instinctive method of grooming their fur with their tongues. Shampoos that are especially designed to be used on pets , commonly dogs and cats , are normally intended to do more than just clean

1947-474: The classical norm (" nòrma classica "), definite articles are masculine lo [lu], feminine la [la], and plural lei/leis [lej/lejz = li/liz]. Nouns and adjectives usually drop the Latin masculine endings, but -e [e] remains; the feminine ending is -a [ɔ]. Nouns inflect for number, all adjectives ending in vowels ( -e or -a ) become -ei/-eis [ej/ejz = i/iz] in some syntactic positions, and most plural adjectives take -s . Pronunciation remains

2006-537: The controversy over the use of shampoo ingredients to mitigate eye sting produced by other ingredients, or the use of the products so formulated. The considerations in 3 and 4 frequently result in a much greater multiplicity of surfactants being used in individual baby shampoos than in other shampoos, and the detergency or foaming of such products may be compromised thereby. The monoanionic sulfonated surfactants and viscosity-increasing or foam stabilizing alkanolamides seen so frequently in other shampoos are much less common in

2773-1020: The pet if it is misused. Generally, insecticidal pet shampoos contain pyrethrin , pyrethroids (such as permethrin and which may not be used on cats) and carbaryl . These ingredients are mostly found in shampoos that are meant to fight against parasite infestations. Antifungal shampoos are used on pets with yeast or ringworm infections. These might contain ingredients such as miconazole , chlorhexidine , providone iodine , ketoconazole or selenium sulfide (which cannot be used on cats). Bacterial infections in pets are sometimes treated with antibacterial shampoos. They commonly contain benzoyl peroxide , chlorhexidine , povidone iodine, triclosan , ethyl lactate , or sulfur.

In 2007, all the ISO 639-3 codes for Occitan dialects, including [prv] for Provençal, were retired and merged into [oci] Occitan. The old codes ([prv], [auv], [gsc], [lms], [lnc]) are no longer in active use, but still have the meaning assigned to them when they were established in the Standard. Some groups have called for Provençal's recognition as

3422-488: Was often relocated overseas. Just 30 years ago most companies were focused on the production of raw materials. However, an overwhelming majority of the modern fragrances contain synthetic chemicals in part or in whole. Grasse perfume companies have therefore adapted by turning to aromatic synthesis and especially to food flavourings and successfully ended a long stagnation. The Grasse perfume industry cannot compete against large chemical multinationals, but it benefits greatly from

3481-411: Was unhealthy not to shampoo several times a week. This mindset is reinforced by the greasy feeling of the scalp after a day or two of not shampooing. Using shampoo every day removes sebum , the oil produced by the scalp. This causes the sebaceous glands to produce oil at a higher rate, to compensate for what is lost during shampooing. According to Michelle Hanjani, a dermatologist at Columbia University,
