Benzyl alcohol is the broad-range partner and is especially associated with Gram-negative bacteria. Benzoic acid and sorbic acid are organic acids used to support protection against bacteria and moulds\/yeasts.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003epH matters.\u003c\/strong\u003e Organic acid preservatives work best when your product is acidic enough to keep them in their active (undissociated) form. Microcare SBB performs best at a final pH of 4.5 – 5.0 and can still be used up to pH 6. Test your finished product with a pH meter or strips and adjust if needed.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eUsing it.\u003c\/strong\u003e The supplier recommends 0.5 – 1.1% in both leave-on and rinse-off products. Microcare SBB has limited solubility in water, so incorporation matters. Add it early in your process, with warming to around 40°C and thorough mixing until the blend is fully dispersed. In emulsions, it is typically added with the heated phases. Avoid prolonged heating, as some of the blend can be lost through evaporation. Always check your finished product for clarity and separation and use preservative challenge testing to confirm it suits your formula.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEvery formula is different, so we recommend preservative challenge testing on your finished product.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSuitable for a range of water-containing products, including:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eShampoos\u003c\/li\u003e\n\u003cli\u003eHair conditioners\u003c\/li\u003e\n\u003cli\u003eStyling gels\u003c\/li\u003e\n\u003cli\u003eLiquid soaps\u003c\/li\u003e\n\u003cli\u003eBath gels\u003c\/li\u003e\n\u003cli\u003eMoisturising creams\u003c\/li\u003e\n\u003cli\u003eBody creams and milks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003eThis product is intended for external use only\u003c\/em\u003e\u003c\/p\u003e","brand":"purenaturenz","offers":[{"title":"50gm","offer_id":46309253480492,"sku":"PR111406","price":10.0,"currency_code":"NZD","in_stock":true},{"title":"100gm","offer_id":46309253513260,"sku":"PR111405","price":15.0,"currency_code":"NZD","in_stock":true},{"title":"250gm","offer_id":46309253546028,"sku":"PR111404","price":27.5,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2971\/2126\/products\/purenaturenz-preservatives-microcaresbb.jpg?v=1790813889","url":"https:\/\/www.purenature.co.nz\/products\/microcare-sbb","provider":"PureNature NZ","version":"1.0","type":"link"}
