Fantasy: Petroleum jelly (Vaseline) used in hair and skin solutions is a perilous chemical byproduct of petroleum or gasoline.
Simple fact: Refined USP Petroleum jelly is not the same as the “Petrolatum” defined by the Chemical Abstract System (CAS) definition found in the EPA Harmful Substances Handle Act (TSCA) Inventory. This CAS number (8009-03-8) applies to an unrefined, large, waxy petrolatum materials. In actuality, United States Pharmacopeia (USP) white petroleum jelly is not a byproduct but is a refined and purified product or service of weighty waxes and paraffinic oils. USP White Petroleum Jelly surpasses the safety requirements set by the Food and drug administration for use in food stuff and cosmetics goods as nicely as for both of those the European Union (EU) and Japanese Pharmacopeia Chemical Codes.
Fantasy: Vaseline or mineral oil when used to the skin generates an impassible barrier plugging hair and pores and skin pores (comedogenic).
Reality: There are no credible scientific reports that establish that Vaseline or mineral oil is in simple fact comedogenic (block skin pores). In reality, the expression comedogenic was formulated by the Food and drug administration to only classify substances that caused zits by blocking facial pores and skin pores. Later, health and fitness and dietary advocates attempted to lengthen this definition to include merchandise applied for the hair and body. Nonetheless, the expression “comedogenic” was never intended to be employed outside of the initial scope as defined by the Food and drug administration. Recently, new scientific scientific studies have resolved the discussion. Complex papers released in the Journal of Beauty Dermatology (May well 24, 2005) and the Journal of the Society of Cosmetic Chemists (1996, vol. 47, pp. 41-48) demonstrated that white USP mineral oil (FG) and white USP Vaseline do not block pores and skin pores.
PJ and mineral are categorized as “occlusive” moisturizers. In principle, occlusives lower water loss from the skin by making a hydrophobic barrier when utilized over the skin. Occlusive moisturizers diffuse into the intercellular lipid domains and herein lay their success. Posted reports present that whilst Vaseline exhibits what seems to be occlusive attributes when utilized to the pores and skin it neither types nor functions as an impermeable barrier but rather permeates slowly but surely all through the SC interstices, enabling for usual pores and skin restoration.
In layman’s phrase Vaseline PJ does not clog pores and skin pores but slowly diffuses in the course of the pores and skin lipid layer and even helps the body in skin restore.
Myth: PJ is reasonably priced lousy moisturizer.
Fact: True, White USP PJ is an low-cost item but on the opposite it is still the most charge-efficient moisturizer employed now in the cosmetic marketplace. Petroleum jelly at minimum concentrations lessens transepidermal h2o reduction (TEWL) by more than 98% and is adopted by lanolin, mineral oil, and the silicones, which are helpful in the variety from 20%-30%. Other substances such as beeswax, stearic acid, shea butter, jojoba oil, coconut oil, and sunflower seed oil TEWL values are under 20 %.
