Description

Composition for eliminating peculiar smell and application thereof Technical Field The invention relates to the technical field of peculiar smell eliminating products, in particular to a composition for eliminating peculiar smell and application thereof. Background Scalp or body odor is a long-felt problem in daily life. Such as malodour generated by reaction of chemicals with hair proteins during hair waving and dyeing, wherein mercapto compounds are the main source of malodour, and these compounds react with keratin in the hair in alkaline conditions, giving rise to a sulphur-like pungent odour. Also, metabolic substances secreted by sweat glands of scalp or body such as urea, amino acids, etc., volatile substances such as ammonia and propionic acid which generate ammonia odor under the decomposition action of bacteria such as staphylococcus, staphylococcus aureus, etc., and in addition, ammonia components can damage the acid-base balance of skin to further aggravate the generation of odor. In addition, different peculiar smells are mutually overlapped and can promote each other, so that vicious circle is formed. The existing products on the market are mostly added with essence substances, so that the effect of covering peculiar smell is realized only from the physical aspect, and the effect is limited. Esters found in nature are mostly ethanol esters of linear carboxylic acids, which are important fragrance ingredients, many of which lower fatty acid esters impart the top note fragrance of fragrances. Besides straight-chain esters, some branched esters and unsaturated esters are also important fragrance materials, and have wide application value in the fields of cosmetics, daily necessities and the like. The Chinese patent application CN110179705A discloses a sterilizing and deodorizing perfume which consists of essence, isopropyl myristate, benzoin, oak extract and the like, and can kill bacteria, so that the generation of secondary odor caused by bacterial decomposition is improved, the fragrance of esters can be emitted, and the problem that the traditional perfume only covers bad odors such as odor, smell and the like is solved. However, thiol compounds and ammonia substances generated by direct metabolism of skin cannot be removed, and the deodorizing effect of multiple integration cannot be realized. Therefore, intensive researches on deodorizing ingredients are still needed at present, and the comprehensive deodorizing effect is realized through the composition, namely, the physical taste masking is realized, and meanwhile, the purpose of fundamentally preventing or removing metabolites generated by skin metabolism and peculiar smell substances generated by the metabolites under the action of bacterial decomposition is considered.
