It delivers remarkable whitening, spot-fading and depigmenting effects in cosmetic and cosmeceutical formulations. Featuring high efficacy and favorable safety profile, 4\u2011butylresorcinol stands out among whitening actives and serves as an ideal option for skincare users<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Composition Information<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Component Type<\/th><th>INCI<\/th><th>CAS<\/th><th>EC<\/th><\/tr><\/thead><tbody><tr><td>Components<\/td><td>4-BUTYLRESORCINOL<\/td><td>18979-61-8<\/td><td><\/td><\/tr><tr><td>Components<\/td><td>LECITHIN<\/td><td>8002-43-5 \/ 8030-76-0 (soybean)<\/td><td>232-307-2 \/ 310-129-7<\/td><\/tr><tr><td>Components<\/td><td>GLYCERIN<\/td><td>56-81-5<\/td><td>200-289-5 <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Mechanism of Action<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">1. Pre-pigment-synthesis stage: Interfere with the synthesis and glycosylation of tyrosinase and reduce its uptake by melanosomes.<br>2. Pigment-synthesis stage: Act as a competitive inhibitor of tyrosinase and TRP\u20111 to reduce the production of pigment-related by-products.<br>3. Post-pigment-synthesis stage: Promote tyrosinase degradation and inhibit melanosome transport to keratinocytes.<br>4. Functional system: The nanomicelle colloid structure improves active ingredient penetration and prolongs the duration of skin-brightening effect.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Experimental Data<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">1. Comparative tyrosinase inhibition test: 10% butylresorcinol encapsulate shows 2.5\u00d7 the potency of hydroquinone, 74\u00d7 of kojic acid and 140\u00d7 of arbutin in inhibiting human tyrosinase.<br>2. Pigment reversibility test: The brightening effect is dose-dependent. Skin tone gradually reverts after discontinuation without damaging melanocyte viability.<br>3. Human keratinocyte inhibition test: 10% butylresorcinol encapsulate exhibits lower suppression on human keratinocyte survival compared with hydroquinone.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nano-micelle self-assembled colloidal delivery system; features solubilization capability, structural stability, low toxicity and small particle size; lower molecular weight enables faster penetration; structurally similar to human liposomes<\/p>\n","protected":false},"featured_media":421,"menu_order":0,"template":"","meta":[],"product_cat":[95],"product_tag":[],"class_list":["post-168","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-meibai-danban-en"],"_links":{"self":[{"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/product\/168","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/media\/421"}],"wp:attachment":[{"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/media?parent=168"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=168"},{"taxonomy":"product_tag","embeddable":true,"href":"http:\/\/duanmu.9ykeji.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=168"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
