PLURAFAC LF 300 is a low-foaming nonionic surfactant based on fatty alcohol alkoxylates.
PLURAFAC LF 300 is designed for formulations where effective wetting, controlled foam, and good cleaning performance are required.
Because of its low-foam character, PLURAFAC LF 300 is especially suitable for automatic dishwashing, rinse-aid systems, hard-surface cleaners, industrial cleaning, and institutional cleaning products.

PLURAFAC LF 300 is supplied as a liquid and is valued for helping formulations spread quickly over surfaces while supporting efficient rinsing and drying performance.
PLURAFAC LF 300 among low-foaming nonionic surfactants, with a cloud point of 22 °C and viscosity of about 75 mPa·s.

PLURAFAC LF 300 is a low foaming nonionic surfactant.
PLURAFAC LF 300 consists of alkoxylated, predominantly unbranched fatty alcohols, and contains higher alkene oxides alongside ethylene oxide.
PLURAFAC LF 300 has a viscosity of approximately 75 mPa·s at 23°C.

PLURAFAC LF 303 stands out especially for its excellent foam-inhibiting action over a wide temperature range and, in view of its superior environmental properties, offers an ideal alternative to the anti-foaming surfactants currently available on the market.

Appli­ca­tions of PLURAFAC LF 300:
PLURAFAC LF 300 is used in automatic dishwashing formulations, rinse aids, and machine-cleaning products where low foam is required.
PLURAFAC LF 300 is suitable for hard-surface cleaners, industrial cleaners, institutional cleaning products, and food-service hygiene formulations.

PLURAFAC LF 300 can also be used in alkaline cleaning systems to improve wetting, surface coverage, rinsing, and drying performance.
Because it is a low-foaming nonionic surfactant, PLURAFAC LF 300 is useful in spray-cleaning, bottle-washing, and food-industry cleaning applications where excessive foam can reduce process efficiency.

The PLURAFAC LF types are com­pat­ible with other non­ionic sur­fac­tants such as our Luten­sol® A, AO, AT, F, GD, ON, XA, XL, XP and TO types and our Plu­ronic® PE and RPE types.
PLURAFAC LF 300 can also be used in com­bi­na­tion with anionic (Luten­sit® A types) and cat­ionic sur­fac­tants (Lutensit TC-KLC types).

They do not react with cal­cium, mag­ne­sium or any of the other cat­ions in hard water, nor with sol­u­ble alkali salts, anionic poly­mers such as car­boxyme­thyl cel­lu­lose, or poly­car­box­y­lates such as our Sok­a­lan® CP, HP, PM and PA types.
PLURAFAC LF 300s in the range that ter­mi­nate in a hydroxyl group are resist­ant to for­mal­de­hyde, chlo­rine com­pounds, phos­phates, sil­i­cates, soda ash, hydrochloric acid, phos­phoric acid, cit­ric acid and most other acids and alka­lis.

This also applies to PLURAFAC LF 1430.
Those that ter­mi­nate in an alkyl group are resist­ant to strong alka­lis such as the alka­lis used in deter­gents for bot­tle-wash­ing machines.

The hydroxyl-ter­mi­nated PLURAFAC LF types can grad­u­ally turn yel­low over pro­longed peri­ods at ele­vated tem­per­a­tures in mod­er­ately alka­line for­mu­lations, but this has no effect on their deter­gency or foam­ing char­ac­ter­is­tics.
Yel­low­ing can often be avoided in pow­der dish­washer deter­gents, etc., by spray­ing the sur­fac­tants onto the phos­phates or carbonates before add­ing the other ingre­dients such as sodium met­a­sil­i­cate, sodium hydrox­ide and a sol­u­ble dich­lo­rois­oc­yan­u­rate.

All of the hydroxyl-ter­mi­nated PLURAFAC LF types are resist­ant to acids, but PLURAFAC LF 220, LF 221 and LF 711 are the most suit­able prod­ucts for use in strongly acidic solu­tions.
Foam­ing Non­ionic sur­fac­tants are renowned for their high deter­gency, wet­ting power and soil-dis­pers­ing capac­ity, but the dis­tin­guish­ing fea­ture of the PLURAFAC LF types is that they form very lit­tle foam.

Some of them can even be employed to inhibit foam for­ma­tion.
Foam­ing can often be a prob­lem in clean­ing pro­cesses that involve inten­sive mechan­i­cal action.

PLURAFAC LF 300 is dif­fi­cult to pre­dict the foam­ing beha­vi­our of sur­factants in advance with stan­dard test meth­ods because of the influ­ence of the type of soil, the type of machin­ery, dif­fer­ent tem­per­a­ture set­tings and the effects of the other ingre­dients in the for­mu­la­tion, etc.
The results obtained by the beater method described in EN 12728, Part 1, or the Ross-Miles method described in DIN 53902, Part 2, and ASTM D 1175-53, have to be sub­stan­tiated with meth­ods that cor­re­spond more closely to real con­di­tions.

One method of test­ing foam for­ma­tion which closely cor­re­sponds to the con­di­tions encoun­tered in prac­tice is to meas­ure the level of foam pro­duced in a dish­washer.
The rotat­ing spray arm is slowed down by foam, and the higher the rate of rev­o­lu­tion, the less foam is present.

Mix­tures of 5 parts of PLURAFAC LF and 95 parts of builder con­sist­ing of 50 % sodium met­a­sil­i­cate, 45 % pen­ta­so­dium tri­phos­phate and 5 % soda ash were tested at a con­cen­tra­tion of 20 g/l.
Foam­ing was encour­aged by add­ing 10 cm3 of egg.

Areas of Appli­ca­tion:
The PLURAFAC LF types are very low-foam­ing non­ionic sur­fac­tants.
PLURAFAC LF 300 is used in deter­gents and clean­ers in which foam­ing has to be kept to a min­i­mum.

PLURAFAC LF 300 can be used in pow­der, paste and liq­uid prod­ucts.
The most impor­tant prod­ucts in this cat­e­gory are deter­gents and rinse aids for domes­tic and com­mer­cial dish­wash­ers, deter­gents for bot­tle-wash­ing machines, and clean­ers for brew­er­ies and dair­ies.

Some of the PLURAFAC LF types can also be used as anti­foams and sur­fac­tants in laun­dry deter­gents.
The PLURAFAC LF types also have appli­ca­tions in clean­ers and degreas­ers for the metal indus­try, in cos­met­ics, and in the oil indus­try.

Benefits of PLURAFAC LF 300:

Low-foam surfactant:
PLURAFAC LF 303 and PLURAFAC LF 305 represent ‘s new generation of low-foam surfactants having excellent application properties and exhibiting a high degree of environmental friendliness.

Favorable environmental profile – numerous application possibilities:
When PLURAFAC LF 300 comes to dishwashers, the main demand made of the anti-foaming and wetting surfactants used is optimal foam suppression during the cleaning process and streak-free, clear rinsing that makes the articles shine spotlessly.
Other required properties are their simple incorporation into formulations as well as a favorable environmental profile characterized by easy biodegradability and low aquatic toxicity.

PLURAFAC LF 303 and PLURAFAC LF 305 are particularly good at meeting all of these requirements.

Chem­i­cal Nature of PLURAFAC LF 300:
The PLURAFAC LF types are low-foam­ing non­ionic sur­fac­tants.
They con­sist of alkox­y­lated, pre­dom­i­nantly ­unbranched fatty alco­hols, and they con­tain higher alkene oxides along­side eth­y­lene oxide.

The fatty alco­hol chains of PLURAFAC LF 131, LF 132, LF 231, LF 431 and LF 1530 ter­mi­nate in an alkyl group.
PLURAFAC LF 731, 7319 and PLURAFAC LF 1430 are spe­cial alkox­y­late.

Solubility of PLURAFAC LF 300:
