羊毛脂的成分：羊毛脂主要來源于綿羊毛，當綿羊在生長過程中，皮脂腺會分泌出一種油脂，用于保護羊毛免受外界環(huán)境的侵害，如雨水、灰塵和微生物的侵蝕，這種油脂便是羊毛脂。在羊毛加工過程中，經(jīng)過洗毛、提取、精制等一系列復(fù)雜工藝，羊毛脂從羊毛中分離出來，成為一種淡黃色至棕黃色的黏稠半固體，具有特殊的氣味。?

Ingredients of lanolin: lanolin mainly comes from sheep wool. During the growth process of sheep, sebaceous glands secrete a type of oil to protect wool from external environmental damage, such as rain, dust, and microbial erosion. This oil is called lanolin. In the process of wool processing, after a series of complex processes such as washing, extraction, and refining, lanolin is separated from wool and becomes a viscous semi-solid ranging from light yellow to brownish yellow, with a special odor. ?

羊毛脂的化學(xué)成分極為復(fù)雜，主要由多種高級脂肪酸與高級脂肪醇所形成的酯類混合物組成，此外還含有游離脂肪酸、甾醇、三萜烯醇及脂肪烴等成分。這些成分相互協(xié)作，賦予了羊毛脂卓越的性能。例如，其中的酯類成分使其具有良好的親膚性和粘附性，能夠在皮膚表面形成一層保護膜；甾醇等物質(zhì)則具有一定的抗炎和抗氧化作用，有助于維護皮膚健康

The chemical composition of lanolin is extremely complex, mainly composed of a mixture of esters formed by various higher fatty acids and higher fatty alcohols, as well as free fatty acids, sterols, triterpenoids, and fatty hydrocarbons. These components work together to endow lanolin with outstanding performance. For example, the ester components in it give it good skin affinity and adhesion, and can form a protective film on the skin surface; Sterols and other substances have certain anti-inflammatory and antioxidant effects, which help maintain skin health

一、良好的親膚性與保濕性?

1、 Good skin friendly and moisturizing properties

羊毛脂與人體皮膚的脂質(zhì)成分相似，因此具有出色的親膚性，能夠迅速被皮膚吸收，且不會引起過敏等不良反應(yīng)。它能夠在皮膚表面形成一層透氣的保護膜，有效阻止水分的蒸發(fā)，從而起到強大的保濕作用。這種保濕效果持久而溫和，對于干燥、缺水的皮膚，羊毛脂能夠深層滋潤，緩解皮膚干燥、起皮等問題，使皮膚保持柔軟、光滑和彈性。?

Lanolin is similar in lipid composition to human skin, therefore it has excellent skin affinity, can be quickly absorbed by the skin, and does not cause adverse reactions such as allergies. It can form a breathable protective film on the surface of the skin, effectively preventing the evaporation of moisture and thus playing a powerful moisturizing role. This moisturizing effect is long-lasting and gentle. For dry and dehydrated skin, lanolin can deeply moisturize and relieve problems such as dryness and peeling, keeping the skin soft, smooth, and elastic.

二、優(yōu)異的粘附性與乳化性?

2、 Excellent adhesion and emulsifying properties

羊毛脂的粘附性使其能夠牢固地附著在各種物質(zhì)表面，無論是皮膚、織物還是金屬等。在化妝品和醫(yī)藥制劑中，這種特性使其成為理想的基質(zhì)材料，能夠幫助其他成分更好地附著和發(fā)揮作用。同時，羊毛脂具有良好的乳化性能，可以將水和油兩種不相溶的物質(zhì)均勻混合，形成穩(wěn)定的乳狀液。這一特性在化妝品的生產(chǎn)中尤為重要，許多乳液、面霜等產(chǎn)品都依賴羊毛脂的乳化作用，以實現(xiàn)良好的質(zhì)地和使用效果。?

The adhesiveness of lanolin enables it to firmly adhere to various material surfaces, whether they are skin, fabric, or metal. In cosmetics and pharmaceutical preparations, this characteristic makes it an ideal matrix material that can help other ingredients adhere and function better. Meanwhile, lanolin has excellent emulsifying properties and can evenly mix two immiscible substances, water and oil, to form a stable emulsion. This characteristic is particularly important in the production of cosmetics. Many lotion, face cream and other products rely on the emulsification of lanolin to achieve good texture and use effect. ?

三、化學(xué)穩(wěn)定性與抗氧化性?

3、 Chemical stability and antioxidant activity

羊毛脂具有較高的化學(xué)穩(wěn)定性，在常溫下不易發(fā)生氧化、分解等化學(xué)反應(yīng)，能夠長期保持其性能穩(wěn)定。其內(nèi)部含有的抗氧化成分，如甾醇等，能夠有效抵御自由基的侵害，防止自身氧化變質(zhì)，同時也有助于保護與之混合的其他成分，延長產(chǎn)品的保質(zhì)期。這使得羊毛脂在儲存和使用過程中更加可靠，減少了因成分變質(zhì)而導(dǎo)致的產(chǎn)品質(zhì)量問題。

Lanolin has high chemical stability and is not prone to chemical reactions such as oxidation and decomposition at room temperature, which can maintain its stable performance for a long time. The antioxidant components contained inside, such as sterols, can effectively resist the invasion of free radicals, prevent self oxidation and deterioration, and also help protect other ingredients mixed with it, extending the shelf life of the product. This makes lanolin more reliable during storage and use, reducing product quality issues caused by component deterioration.
